🎨 Theming

We expose some CSS Variables to make more easy customize the colors of the component:

Variable	Description
--srTriggerBg	Define the background color of default Trigger component
--srTriggerColor	Define the text color of default Trigger component
--srTriggerHoverBg	Define the background hover color of default Trigger component
--srTriggerContainerBoxShadow	Define the style box shadow of the reactions container
--srTriggerContainerBg	Define the background color of the reactions container
--srReactionClickedBg	Define the background color of reaction block when this is already clicked
--srReactionNotClickedBg	Define the background color of reaction block when this is not already clicked
--srReactionHoverBg	Define the background hover color of reaction block
--srReactionClickedHoverBg	Define the background hover color of reaction block when this is already clicked
--srEmojiColor	Define the text color of reaction
--srEmojiClickedColor	Define the text color of reaction when this is already clicked
--srLabelBorderColor	Define the border color of default label component
--srLabelClickedBorderColor	Define the border color of default label component when reaction is already clicked
--srLabelBg	Define the background color of default label component
--srLabelClickedBg	Define the background color of default label component when reaction is already clicked
--srLabelColor	Define the text color of default label component
--srLabelClickedColor	Define the text color of default label component when reaction is already clicked
--srLabelHoverBg	Define the background hover color of default label component
--srLabelClickedHoverBg	Define the background hover color of default label component when reaction is already clicked

Then you can use this variables to customize the component, for example:

<!-- CustomReactionComponent.svelte -->
    
<script>
    import { Trigger } from 'svelte-reaction';
    
    export let reactions;
    export let showLabels = true;
    export let position = 'bottom-left'
</script>
    
<Trigger {reactions} {showLabels} {position} />

<style global>
    :root {
        --srTriggerBg: red;
        --srTriggerHoverBg: blue;
        --srTriggerColor: white;
     }
</style>

If you need to be more strict, always you can overwrite the next classes to get the better result:

Class name	Description
.trigger-container	Default class for default trigger and labels container
.trigger	Default class for default trigger element
.reactions-container	Default class for the reactions contanier (floating component)
.reaction	Default class for the reaction element
.emoji	Default class for the emoji element
.labels-container	Deault class for the labels container
.label	Default class for the label element
.label-component	Default class for the label element, when the reaction is defined as SvelteComponent insted of String

Remember alway use global styles for overwriting CSS variables and classes
