Removing the Outline from Select Boxes in Firefox
The outline surrounding a selected item in a select element can be visually distracting. This article explores how to remove this outline in Firefox, despite the ineffectiveness of the outline CSS property.
Failed Attempts Using CSS
Adding the outline property with a value of none in CSS does not remove the outline in Firefox:
select { outline:none; }
Bulletproof Solution Using the Pseudo-Class
A more robust solution involves using the Firefox-specific pseudo-class:-moz-focusring:
select:-moz-focusring { color: transparent; text-shadow: 0 0 0 #000; }
This code applies the following styles to the:-moz-focusring pseudo-class:
- Sets the color to transparent, hiding the outline.
- Adds a text shadow of size 0 to prevent any changes in the font appearance.
Applying this style ensures that the dotted outline is removed only in Firefox, without affecting other browsers. This solution provides a reliable and browser-specific method for removing the outline from select boxes.
