For anchors that act like buttons (for example, the buttons on the sidebar of this Stack Overflow page titled , , and ) or tabs, is there a CSS standard way to disable the highlighting effect if the user accidentally selects the text? I realize that this could be done with JavaScript and a little googling yielded the Mozilla-only -moz-user-select option. Is there a standard-compliant way to accomplish this with CSS, and if not, what is the "best practice" approach?

Sure! Here's a standard-compliant approach to disabling text selection highlighting on anchors with the href attribute:

1. Use the text-decoration: none; property:

a {
  text-decoration: none;
}

2. Set the cursor property to pointer for the anchor:

a {
  cursor: pointer;
}

3. Use the user-select property on the <a> element:

a {
  user-select: none;
}

4. Use the pointer-events: none; property for the parent container:

.container {
  pointer-events: none;
}

5. Use JavaScript to intercept the text selection event:

document.addEventListener("selectionchange", function(event) {
  event.preventDefault();
});

6. Set the tabindex attribute to a non-negative value:

<a href="#" tabindex="1">Link</a>

Best Practice Approach:

  • Combine the text-decoration: none; and pointer-events: none; properties to ensure that text selection is disabled entirely.
  • Ensure that the parent container is set to tabindex to ensure that keyboard navigation still works as expected.

Additional Tips:

  • You can use the outline property to draw a visible outline around the anchor to distinguish it from other elements.
  • Use the transition property to make the transition between normal and selected states smooth.

By implementing these techniques, you can achieve the desired behavior of disabling text selection highlighting while maintaining accessibility and keyboard navigation functionality.

To disable text selection highlighting on HTML elements that act as buttons or tabs, you can use the CSS user-select property. This property is a standard CSS property that is supported by all major browsers, including Chrome, Firefox, Safari, and Edge.

Here's the CSS code to disable text selection highlighting:

.my-button {
  -webkit-user-select: none; /* Safari */
  -ms-user-select: none; /* IE 10 and IE 11 */
  user-select: none; /* Standard syntax */
}

The user-select property has the following values:

  • none: Disables text selection on the element.
  • auto: Allows the browser to determine whether text selection is allowed or not (the default behavior).
  • text: Allows text selection on the element.
  • all: Allows the selection of the entire element, including any text it contains.

The -webkit-user-select and -ms-user-select properties are vendor-prefixed versions of the user-select property, which are required for older browser versions (such as Safari and Internet Explorer) to work correctly.

Here's an example of how you can apply this to your anchor-based buttons or tabs:

<a href="#" class="my-button">Button 1</a>
<a href="#" class="my-button">Button 2</a>
<a href="#" class="my-button">Button 3</a>
.my-button {
  -webkit-user-select: none; /* Safari */
  -ms-user-select: none; /* IE 10 and IE 11 */
  user-select: none; /* Standard syntax */
  cursor: pointer;
  display: inline-block;
  padding: 8px 16px;
  background-color: #f1f1f1;
  border: 1px solid #ddd;
  border-radius: 4px;
}

.my-button:hover {
  background-color: #e6e6e6;
}

This is the standard and recommended approach to disabling text selection highlighting on interactive elements like buttons or tabs. It works across all major browsers and provides a consistent user experience.

To disable text selection highlighting in a cross-browser manner using CSS, you can use the user-select property along with its vendor prefixes. Here's how you can achieve this:

.no-highlight {
  -webkit-user-select: none; /* Safari */
  -moz-user-select: none; /* Firefox */
  -ms-user-select: none; /* IE10+/Edge */
  user-select: none; /* Standard syntax */
}

Explanation:

  • The user-select property is used to control whether the text can be selected or not.
  • Setting the value to none disables text selection for the element and its children.
  • The -webkit-, -moz-, and -ms- prefixes are used for browser compatibility with older versions of Safari, Firefox, and IE10+/Edge, respectively.
  • The standard syntax user-select: none; works in modern browsers without the need for prefixes.

To apply this style to your anchor elements that act as buttons or tabs, you can add the no-highlight class to those elements:

<a href="#" class="button no-highlight">Click me</a>

This will prevent the text within the anchor from being highlighted when accidentally selected.

It's worth noting that while this CSS approach is widely supported, it's not part of the official CSS standard. However, it is considered a best practice and is commonly used for this purpose.

Alternatively, if you want to use JavaScript to achieve the same effect, you can use the onselectstart event and prevent the default behavior:

<a href="#" class="button" onselectstart="return false;">Click me</a>

Or, you can add the event listener using JavaScript:

document.querySelector('.button').addEventListener('selectstart', function(e) {
  e.preventDefault();
});

Both the CSS and JavaScript approaches effectively disable text selection highlighting for the specified elements.

Yes, you can disable text selection highlighting using CSS across modern browsers. The user-select property is now supported by all major browsers, including Firefox, Chrome, Safari, and Edge. This property allows you to control whether or not a user can select text on an element.

To disable text selection highlighting for anchors that act like buttons or tabs, you can use the following CSS code:

a.button, a.tab {
  -webkit-user-select: none; /* Chrome, Safari, and Opera */
  -moz-user-select: none; /* Firefox */
  -ms-user-select: none; /* Internet Explorer/Edge */
  user-select: none; /* Standard syntax */
}

Here, replace a.button and a.tab with your actual class names for anchors acting as buttons or tabs.

This "best practice" approach ensures consistent behavior across different browsers, providing a smooth user experience on your web page.

There is no standard CSS property to disable text selection highlighting across all browsers. However, there are vendor-prefixed CSS properties that can achieve this effect, but with varying levels of browser support.

Here's how you can disable text selection highlighting using CSS:

.no-highlight {
  /* Disable text selection on modern browsers */
  user-select: none;

  /* Disable text selection on Firefox */
  -moz-user-select: none;

  /* Disable text selection on Safari and older WebKit browsers */
  -webkit-user-select: none;

  /* Disable text selection on Internet Explorer/Edge */
  -ms-user-select: none;
}

To apply this CSS rule, you can add the no-highlight class to the elements where you want to disable text selection highlighting, like this:

<a href="#" class="no-highlight">Button-like Link</a>

It's important to note that while this approach works in most modern browsers, it may not be supported in older or less popular browsers. Additionally, some users may have accessibility settings that override this behavior, allowing text selection even on elements where it's disabled.

If you need to support older browsers or prioritize accessibility, the recommended "best practice" approach is to use JavaScript to handle text selection events and prevent the default behavior. This approach provides more control and flexibility, but it also adds complexity to your code.

Here's an example of how you can disable text selection highlighting using JavaScript:

// Get all elements where you want to disable text selection
const noHighlightElements = document.querySelectorAll('.no-highlight');

// Add event listeners to prevent text selection
noHighlightElements.forEach(element => {
  element.addEventListener('selectstart', preventSelection);
  element.addEventListener('mousedown', preventSelection);
});

// Function to prevent text selection
function preventSelection(event) {
  event.preventDefault();
}

This JavaScript code selects all elements with the no-highlight class and adds event listeners to prevent text selection on those elements. When the user tries to select text on those elements, the preventSelection function is called, which uses the event.preventDefault() method to cancel the default text selection behavior.

By combining CSS and JavaScript approaches, you can achieve a more robust and accessible solution for disabling text selection highlighting on button-like links or tabs.

The standard way to disable text selection highlighting with CSS is by using the -webkit-user-select property, which works on both Chrome and Safari browsers. Set its value to "none", like so:

a {
  -webkit-user-select: none; /* For Safari users */
}

This will disable text selection for any element with the <a> tag in your document, including links that appear to be buttons or tabs. This way you're avoiding a JavaScript solution and adhering to CSS standards.

However, do note that this feature is still experimental as of the writing of this response, and its support may not yet have been implemented in all browsers. For full cross-browser compatibility with text selection highlighting disabled, use both -webkit-user-select for Safari/Chrome (desktop) and -moz-user-select for Mozilla Firefox (desktop).

For example:

a {
    -webkit-user-select: none; /* For Safari users */
    -moz-user-select: none;     /* For Firefox users */
}

As the specification itself says that none property only disables highlighting in user select, but not programmatically by scripts or other developers. It's a behavior for users instead of application developers.

If you want to prevent accidental text selection entirely and your website is meant as read content rather than input/editing area (as most websites are), it may be best to consider removing the ability to select text altogether with user-select: none; in CSS, for instance:

body {
  user-select: none;
}

This will block any kind of text selection across all elements on your site. Use this sparingly though as it might disrupt a user's experience when they need to highlight content while communicating with you or elsewhere. It is typically reserved for cases where the content can be edited (like in an admin panel).

Again, do note that this feature may still not have universal browser support as of current standards. Please check Can I use for comprehensive coverage of which browsers/versions support a specific CSS property and behavior.

CSS Standard Way (for Modern Browsers)

Unfortunately, there is no CSS standard to disable text selection highlighting for all browsers. However, some modern browsers support the user-select property:

user-select: none;

This will disable text selection for the element it is applied to.

Cross-Browser Approach

To achieve cross-browser compatibility, you can use a combination of CSS and vendor prefixes:

-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;

Best Practice Approach

If you need to disable text selection for legacy browsers, it is recommended to use JavaScript. Here's a simple cross-browser function:

function disableTextSelect(element) {
  element.onselectstart = function() {
    return false;
  };
}

You can then apply this function to the desired elements:

disableTextSelect(document.getElementById("myButton"));

Note:

  • The user-select property may not work in all cases, especially for elements that are inherently selectable (e.g., input fields).
  • The JavaScript approach is more reliable but may have performance implications.

Unfortunately, there isn't a standard-compliant way to completely disable text selection highlighting using only CSS. The user-select property in CSS does exist, but it is not well-supported across all browsers and has limited use cases.

The user-select: none; property can be used to prevent selection of an element, but this will also prevent the user from selecting text within the element for copying or drag-and-drop functionality. It does not hide the highlighting effect when the user accidentally selects text, but instead makes it impossible for them to select the text in the first place.

The most common approach for buttons and tabs, which you're asking about, is to use a combination of CSS and JavaScript:

  1. Use CSS to style the buttons and tabs as visual indicators with clear labels.
  2. Use JavaScript to listen for mousedown or touchstart events on the elements, disable text selection within that element, and highlight it visually when it's active. You can refer to existing libraries like jQuery UI or Tether for such functionality.

By following this approach, you can provide users with clear visual indicators, disable unwanted text selections when they interact with these indicators, and maintain usability features like copying and drag-and-drop on the rest of your website.

Yes, there are some CSS standards that can be used to disable text selection highlighting in anchor tags that resemble buttons or tabs. One of these options is the --moz-user-select property, which disables the default highlighter for the selected element.

However, it's important to note that not all browsers support this option, so it may not work as expected on all websites. In addition, using CSS alone to disable highlighting may not be enough to handle all situations, as other factors such as the user interface and behavior can affect how the text is highlighted or not.

For more complex cases where you want to completely disable all highlighting for a particular element, it's recommended to use JavaScript instead of solely relying on CSS. This allows you to customize the behavior based on individual user interactions and other factors such as the type of text being highlighted or the overall layout of the page.

Yes, there is a standard-compliant way to accomplish this with CSS. One approach is to use the text-shadow property in CSS. This property allows you to create an overlay of shadows around any text element that uses it. To disable the highlighting effect if the user accidentally selects the text, you can modify the value of the text-shadow property on the specific elements of your HTML document that contain the text you want to disable highlighting for. For example, in this hypothetical scenario where a webpage has a button labeled "Click me!" and another button labeled "Another Button!" and some other text elements), to disable the highlighting effect if the user accidentally selects the text for these specific elements of the website, you could modify the value of the text-shadow property on the following specific elements of your hypothetical scenario's website:

For anchors acting as buttons (like the "ask question" button, the "tour" button, and the "help center" button at the top right of this page), it is standard compliant to disable text selection highlighting using JavaScript. One way of doing that is by setting the style on the anchor elements using JavaScript when the page loads:

let anchors = document.getElementsByClassName("button-or-tab");
for (const anchor of anchors) {
  anchor.style.userSelect = "none";
}

The userSelect CSS property with the value none disables text selection and highlighting for any element on which it is applied, in this case all of the buttons and tabs. This code uses JavaScript to modify the CSS styling after the page loads to prevent accidental highlights when users try to select them with their mouse. This can also be accomplished by adding the user-select: none; property to a common stylesheet included on every page (such as global.css) and applying it to all of the button-like elements in your page's HTML using CSS classes or IDs, like this:

/* In global.css */
.button-or-tab {
  -moz-user-select: none;
}

This will set the user-select style to "none" for any element in your page that has a class of "button-or-tab". You can then apply that class to any of your buttons and tabs using their respective HTML tags, like this:

<a href="/" class="button-or-tab">Ask question</a>
<a href="tour" class="button-or-tab">Tour</a>
<a href="help-center" class="button-or-tab">Help Center</a>

By doing this, you are making your buttons and tabs unselectable for all users across the board. This is a good way to prevent accidental highlights of text that may be confusing for the user or even dangerous on pages like Stack Overflow, which involve form inputs with sensitive data.

Text Selection Highlighting Disabling for Anchors

Currently, there's no standard-compliant way to disable text selection highlighting for anchors using only CSS. While the -moz-user-select property is a workaround for Firefox, it's not a widely-used solution and not recommended.

Best Practice:

The best practice approach is to use JavaScript to handle the text selection highlighting behavior. Here's how:

  1. Event Listener: Listen for the mousedown event on the anchor element.
  2. Capture Mouse Down: Capture the mouse pointer's position when the user clicks on the anchor.
  3. Selection Check: Check if the user has selected any text on the page. If they have, prevent the default highlighting behavior.

Additional Solutions:

  • Background Images: Use background images for your anchors instead of relying on the text selection highlighting. This will prevent the highlighting altogether.
  • Border or Outline Styles: Apply border or outline styles to the anchors instead of text selection highlighting.
  • Custom Highlight: Create a custom highlight style that resembles the desired behavior and apply it to the anchors. This can be more visually appealing than the default highlighting.

Example Code:

const anchorEl = document.getElementById('my-anchor');

anchorEl.addEventListener('mousedown', function(e) {
  if (window.getSelection()) {
    // User has already selected text, prevent default highlighting
    e.preventDefault();
  }
});

Note: This solution will prevent text selection highlighting for all anchors on the page. If you want to target specific anchors, you can modify the code to target those specifically.

According to Can I use, the user-select + -webkit-user-select is enough to achieve desired behavior in all major browsers.


These are all of the available correct CSS variations:

.noselect {
  -webkit-touch-callout: none; /* iOS Safari */
    -webkit-user-select: none; /* Safari */
     -khtml-user-select: none; /* Konqueror HTML */
       -moz-user-select: none; /* Old versions of Firefox */
        -ms-user-select: none; /* Internet Explorer/Edge */
            user-select: none; /* Non-prefixed version, currently
                                  supported by Chrome, Edge, Opera and Firefox */
}
<p>
  Selectable text.
</p>
<p class="noselect">
  Unselectable text.
</p>

Note that user-select is in standardization process (currently in a W3C working draft). It is not guaranteed to work everywhere and there might be differences in implementation among browsers. Also, browsers can drop support for it in the future.


More information can be found in Mozilla Developer Network documentation. The values of this attribute are none, text, toggle, element, elements, all and inherit.
