CSS allows designers to remove the focus border outline from an element when it is clicked or tabbed to. This is useful in cases where the focus ring may be undesirable or not fit with the design aesthetic.
To remove the focus outline from an element, use the :focus
pseudo-class and set the outline
property to none
.
:focus {
outline: none;
}
It's important to note that removing the focus outline can make it difficult for users to navigate your website with a keyboard. It's recommended to use an alternative visual cue to show when an element is focused.
Let's say we have a button element that should change color when it is clicked. We don't want a focus outline to appear after it has been clicked, so we can include the CSS code below to remove the outline.
<button class="btn">Click Me</button>
.btn:focus {
outline: none;
}
.btn:active {
background-color: blue;
color: white;
}
This code will remove the focus outline when the button is clicked, and will change the button's background color to blue and text to white.
The ability to remove the focus outline from an element using CSS can be useful, but it's important to maintain accessibility and usability for all users, including those who rely on keyboard navigation. Consider using alternative visual cues to indicate focus.
