How Do I Remove the Blue Dotted Outline in Firefox Select Elements?

Undoing the Blue Dotted Outline in Firefox Select Elements

When a selection is made in a standard select box, a dotted blue outline often appears around the selected item. This can be a visual distraction or interfere with the user experience, particularly on smaller form factors. While CSS's outline property can typically remove this outline, it doesn't always work in Firefox.

Cross-Browser Solution

To achieve a truly cross-browser solution, the following CSS rule can be used:

<code class="css">select:-moz-focusring {
    color: transparent;
    text-shadow: 0 0 0 #000;
}</code>

Specific to Firefox

This CSS rule targets Firefox specifically and effectively removes the dotted outline from the selected option.

Consider Accessibility

While removing the dotted outline can improve the visual aesthetics, it's important to consider accessibility implications. The outline can serve as a visual cue for visually impaired users to identify the selected item. Therefore, use this solution judiciously and consider alternative accessibility enhancements.
