[BUG] Shopify Theme Editor Section Visual Preview is Broken

Hello Shopify Devs,

In Shopify, before adding a section, there’s a visual preview. Recently I noticed that in this preview, my custom built sections are broken, because {{ section.id }} includes invalid characters which break the section.

Example:

{% style %}
.section#section_{{ section.id }} {
  --text-color: red;
}
{% endstyle %}

<div class="section" id="section_{{ section.id }}">
  <h2 style="color: var(--text-color)">Hello there</h2> // text is not red
</div>

everywhere besides the visual preview, {{ section.id }} looks like:

section_template--25013359542583__abcd

This is valid and works fine for the id attribute.

However, In visual preview, {{ section.id }} looks like:

section_template--25013359640887__eyJzZWN0aW9uIjoiYWRldi1pbWFnZS13aXRoLXRleHQtdjIiLCJzaWduYXR1cmUiOiJOZXcgSW1hZ2Ugd2l0aCBUZXh0IFYyIn0=

This contains =, which is not valid in an HTML id

which breaks the section styles and javascript that use the section.id

Hope this can be fixed asap.

Hello @arifursdev,

While I’m not sure about what happens with the section ID, I can recommend the following:

{% style %}
  #shopify-section-{{ section.id }} {
    --text-color: red;
  }
{% endstyle %}

<div class="section">
  <h2 style="color: var(--text-color)">Hello there</h2>
</div>

Or you can go even further based on your needs:

{% style %}
  #shopify-section-{{ section.id }} {
    --text-color: red;

    & h2 {
      color: var(--text-color);
    }
  }
{% endstyle %}

<h2>General Kenobi</h2>

{% schema %}
  {
    "class": "section" 
  }
{% endschema %}

In the context of a section, a wrapper element generated by Shopify already has an ID you can reference for your dynamic styles. This one surely is less bound to break as I use this exact pattern daily.

Hello,

Although this is about the {{ section.id }} output being invalid for id attribute;

I was wondering if you could share what’s wrong with my code even though this is not what I’m actually doing, but it was just an example.

20 days have passed, and the issue remains unfixed. This forum feels completely useless.
