Can I Change the Color for the Images for Hover, Active, Etc., Via CSS?

Yes, you can customize the color effects of reaction icons to differentiate between active icons and others using CSS. The DaReactions plugin allows you to apply various visual effects such as blur, transparency, and grayscale directly through CSS. If you prefer to use custom CSS effects instead of the built-in fade method, you can disable the default effects and add your own styles to the theme.

Customizing Icon Colors with CSS

To customize the color effects of reaction icons, you can add the following CSS rules to your theme’s stylesheet. These examples demonstrate how to apply different effects based on the user interaction with the reaction icons:

1. Hover Effect on Unvoted Buttons:
   • Apply a sepia filter to reaction icons when hovered over, but not yet voted:

div.da-reactions-container div.reaction:hover img {
    filter: sepia(100%);
} 

2. Active Reaction:
   • Keep the default colors for the reaction icon that has been voted on (active):

div.da-reactions-container.has_current div.reaction.active img {
    filter: none;
} 

3. Non-active Reactions in Voted Group:
   • Apply a grayscale filter to other reactions in a group that contains a vote by the user:

div.da-reactions-container.has_current div.reaction img {
    filter: grayscale(100%);
} 

4. Hover Effect on Voted Group:
   • Change to negative colors when hovering over reactions in a group that already contains your vote:

div.da-reactions-container.has_current div.reaction:hover img {
    filter: invert(100%);
} 

Tips for Implementing Custom CSS

• Add CSS to Your Theme: Incorporate these styles into your theme’s main CSS file or through the custom CSS section if your theme or WordPress setup provides one (usually found under Appearance > Customize > Additional CSS).
• Testing Changes: After applying the new styles, make sure to clear your browser cache and refresh your pages to see the effects take place.
• Backup: Always make a backup of your existing CSS files before making substantial changes, especially if you are editing the theme files directly.

By customizing the CSS for reaction icons, you can enhance the visual feedback for user interactions, making the experience more engaging and suited to your site’s design ethos.
