Use svelte css class in @html

I have an api that returns html with classes, I want to know how I can use svelte style definition for those.

App.Svelte

<script>
    let string = `<span class="status">ok</span>`;
</script>

<p>{@html string}</p>

<style>
    .status {
        color: red
    }
</style>
... 

{@html marked}

Returns Unused CSS selector (8:1)

There is one alternative which you may find more appealing than :global(), depending on your situation.

You can choose to import CSS and have it only flow down to child pages within your project.

For example if you have a structure like this:

routes/app
       +layout.svelte
       /subpages
      /portal
       +layout.svelte
       /subpages
      /marketing
       +layout.svelte
       /subpages

You can import CSS into the section of the layout in any one of the above layouts and only have it apply to all the child pages beneath it.

<script>
   import "../styles/marketing.styl"
</script>

I was trying to do this with the h2 tag, since I am integrating tincyMCE in a svelte app that is using 'flowbite-svelte'. What worked for me was:


    :global(.content h2) {
        font-size: 1.5em;
      }

Where 'content' was my div class.

Svelte will remove all CSS it cannot find in the markup, which is why it's removing the status class in your sample. There is however a way to tell Svelte to leave these classes alone and that's by simply declaring them global:

:global(.status) { }

Beware that this would apply these styles to ALL .status classes in your app, to still have some scoping you could make this a child selector somehow


<style>
 .wrapper > :global(.status) {
 }
</style>

<div class="wrapper">
  {@html marked}
</div>

This way it will only be applied to status classes inside of wrapper.
