Fixing Responsive Layouts: How to Master Container Queries for Custom Sections in Shopify's Savor Theme

Hey everyone! I recently jumped into a really insightful discussion on the Shopify community forums that I just had to share with you. It touched on a common pain point for store owners trying to customize their themes, especially when it comes to responsive design. The thread, originally titled "Responsive Layout Issue with Custom Video Review Section (Savor Theme)", perfectly highlighted a subtle but significant difference in how your custom sections might behave compared to your theme's native ones.

Our fellow merchant, dreamtechzone_5, was wrestling with a custom video review section they'd added to their product page on the Savor theme. The problem? While the theme's built-in "Recommended Products" section looked great and adjusted perfectly across different screen sizes and zoom levels, their custom video section was, well, misbehaving. It would get cramped, display too many columns, or just generally look off as the browser window changed. It's a frustrating experience when you've put effort into a custom section, only to find it doesn't play nicely with the rest of your store's design.

Understanding the Core Problem: Viewport vs. Container Queries

The beauty of the Shopify community is how quickly experts can pinpoint the underlying issue. As ai-theme-code-editor initially suggested, the problem often boils down to how different sections handle responsiveness. The Savor theme, like many modern Shopify themes, leverages a powerful CSS feature called container queries for its native sections. Think of it this way:

• Viewport media queries (the traditional @media screen and (min-width: ...) you might be familiar with) tell an element to respond to the overall browser window size.
• Container queries (@container (min-width: ...)), on the other hand, tell an element to respond to the size of its immediate parent container. This is a game-changer for modular design!

The custom video section was using the older viewport media queries, meaning it was trying to arrange its columns based on the entire browser width. But the "Recommended Products" section was using container queries, allowing it to adapt gracefully within its own designated space, regardless of how wide the browser window was. This mismatch led to the video section forcing too many columns into a smaller space, making it look cramped and unpolished, as shown in this screenshot:

The Fix: Embracing Container Queries

Thankfully, ajaycodewiz, a real pro in the community, provided a clear, actionable solution. The fix involves a couple of straightforward changes within your custom video section's code to switch it over to using container queries, just like the rest of the Savor theme.

Step-by-Step Instructions:

Here’s how you can implement this fix for your own custom sections, specifically targeting the ugc-video-grid.liquid file (or whatever your custom video section is named) in your Savor theme:

1. Navigate to Your Theme Code:
   • From your Shopify admin, go to Online Store > Themes.
   • Find your Savor theme, click Actions > Edit code.
2. Open Your Custom Section File:
   • In the file editor, look under the sections/ directory.
   • Open your video section file. Based on the code dreamtechzone_5 shared, it's likely named something like ugc-video-grid.liquid, but it could vary.
3. Modify the Grid Layout CSS:

   Locate the {% style %} block within this file. Inside, find the CSS rules for your grid layout. You'll want to replace the existing grid block with the following code. This snippet introduces container-type: inline-size; on the wrapper and changes the @media screen rules to @container rules.

   .section-{{ section.id }} .ugc-grid-wrapper {
     container-type: inline-size;
   }
   
   .section-{{ section.id }} .ugc-grid-layout {
     display: grid;
     gap: {{ section.settings.column_gap_mobile }}px;
     grid-template-columns: repeat({{ section.settings.columns_mobile }}, minmax(0, 1fr));
   }
   @container (min-width: 750px) {
     .section-{{ section.id }} .ugc-grid-layout {
       gap: {{ section.settings.column_gap_tablet }}px;
       grid-template-columns: repeat({{ section.settings.columns_tablet }}, minmax(0, 1fr));
     }
   }
   @container (min-width: 990px) {
     .section-{{ section.id }} .ugc-grid-layout {
       gap: {{ section.settings.column_gap_desktop }}px;
       grid-template-columns: repeat({{ section.settings.columns_desktop }}, minmax(0, 1fr));
     }
   }

   After this change, your video section will now read its own width and adjust its columns accordingly, just like the native sections. You'll see a much cleaner layout, even at those tricky intermediate browser widths.

   
4. Align the Heading Breakpoints:

   ajaycodewiz also pointed out a small but important detail: the heading's breakpoints for font size changes were slightly different (768px / 1024px) than the grid's (750px / 990px). For a truly seamless experience, you should adjust these as well. Find these lines in your {% style %} block:

   @media screen and (min-width: 768px) {
     .section-{{ section.id }} .ugc-heading {
       font-size: {{ section.settings.heading_size_tablet }}px;
     }
   }
   @media screen and (min-width: 1024px) {
     .section-{{ section.id }} .ugc-heading {
       font-size: {{ section.settings.heading_size_desktop }}px;
     }
   }

   And change them to:

   @media screen and (min-width: 750px) {
     .section-{{ section.id }} .ugc-heading {
       font-size: {{ section.settings.heading_size_tablet }}px;
     }
   }
   @media screen and (min-width: 990px) {
     .section-{{ section.id }} .ugc-heading {
       font-size: {{ section.settings.heading_size_desktop }}px;
     }
   }

   This ensures your heading and grid switch their layouts at the exact same point, providing a more consistent and professional look.

5. Save Your Changes:

   Don't forget to hit that Save button! Then, clear your cache and check your store on various devices and by resizing your browser window to see the magic happen.

It's these kinds of details that truly elevate a custom section from "functional" to "flawless." By understanding how your theme handles responsiveness and aligning your custom code with those methods, you can ensure a consistent and professional user experience across your entire store. This little deep dive into container queries is a fantastic example of how powerful modern CSS can be for creating dynamic layouts.
