How Can I Remove the Default Browser Focus Highlight from Input Elements While Maintaining Accessibility?

Removing the Border Highlight on Input Text Elements

When an input element receives focus, browsers like Safari and Chrome add a blue border around it. This can be visually distracting or conflict with the desired design aesthetic.

Solution:

To remove the border highlight, use CSS to set the outline-width property to 0 when the input element is focused:

input.middle:focus {
    outline-width: 0;
}

This will eliminate the border highlight specifically for input elements with the middle class.

Accessibility Considerations:

Note that the focus outline is an important accessibility feature, as it indicates the currently focused element. Removing it completely can hinder accessibility for users who rely on this visual cue. Instead, consider using the outline property to customize the appearance of the focus outline, such as making it transparent or a different color.

Other Elements:

The same approach can be used to remove the border highlight on other form input elements, such as selects, textareas, and buttons:

input:focus,
select:focus,
textarea:focus,
button:focus {
    outline: none;
}

Advanced Options:

For elements with the contenteditable attribute, which essentially allows any element to become a text editor, use this CSS:

[contenteditable="true"]:focus {
    outline: none;
}

Disable for Everything:

If desired, you can disable the focus outline on all elements with this CSS:

*:focus {
    outline: none;
}

However, this is generally not recommended, as it may hinder accessibility for users who rely on the focus outline feature.
