CSS outline-color Property – FAQs
What does the outline-color property do in CSS?
The outline-color property in CSS specifies the color of the outline that surrounds an element, which is typically drawn outside the border edge. It is used to enhance the visibility and focus of elements like buttons or input fields.
How can I change the outline color of an element to red?
You can change the outline color by using: outline-color: red;. This will set the outline color to red for the selected element.
Is it possible to use transparent colors with outline-color?
Yes, you can use transparent colors by specifying an RGBA value. For example: outline-color: rgba(255, 0, 0, 0.5); will apply a semi-transparent red outline.
Does outline-color affect the border color?
No, the outline-color does not affect the border color; it is a separate property that only changes the color of the outline around the element.
How does outline-color interact with the outline-style property?
The outline-color works in conjunction with the outline-style property. For the color to be visible, an outline style (such as solid, dotted, or dashed) must be set.
