Eliminating Annoying Side Strips: A Shopify Section Background Fix from the Community
Hey store owners! Ever been there? You're meticulously crafting your Shopify store's look, trying to get everything just right, and then you hit a snag. A section looks almost perfect, but there are these stubborn, unchangeable strips of a different color peeking out on the sides. It's frustrating, right? It breaks the clean, professional look you're going for.
That's exactly what Tammy_29 from Pretty Twinkles ran into recently on the Shopify community forums. She was using the AI-generated feature to create a beautiful section with two image cards, but those side panels just wouldn't cooperate with her desired unified background color, #fbecee. She shared a screenshot, and it was clear what she meant – two darker strips flanking her otherwise perfectly colored content. It’s a common scenario, and thankfully, the community stepped in with some excellent advice.
Understanding the Problem: Section vs. Block Backgrounds
When you encounter these kinds of visual inconsistencies, especially with background colors, the first thing to remember is the hierarchy of your theme's structure. As alaattincagil wisely pointed out in the discussion, often the issue isn't with the individual 'block' (like Tammy's 'Two image cards') but with its 'parent' – the overarching 'Section' that contains it.
Think of it like this: your blocks are pieces of furniture, and the section is the room they're in. If you paint the furniture, but the walls of the room are a different color, you'll still see those walls around the edges. In Tammy's case, even though she'd set the 'Cards area background' and 'Card background' to #FBECEE, those outer strips remained because they belonged to the section itself, which didn't have a matching full-width background setting.
First Approach: Checking Your Theme Settings
Before diving into code, it's always best to check if your theme offers a direct solution. This is where alaattincagil's advice comes in handy. Many modern Shopify themes, especially those built on Dawn, offer robust customization options directly in the theme editor.
Here's how you'd typically investigate this:
- Go to your Online Store in your Shopify admin.
- Click Customize next to your current theme.
- In the theme editor, locate the section that's giving you trouble.
- Close the settings for any inner blocks (like 'Two image cards') by clicking the 'X' next to their name in the left sidebar.
- Click on the parent item labelled 'Section' in the left sidebar (it should be just above your specific block).
- Look for a Background or Color scheme setting within that section's options.
If you find a color scheme option, you might need to create a new, dedicated color scheme under Theme settings → Colors. Set its background to your desired color (e.g., #FBECEE), then assign that new scheme to your problematic section. This ensures you don't accidentally change the background of other sections that might be sharing an existing color scheme.
The Power of Custom CSS: When Theme Settings Fall Short
Sometimes, even after checking all the theme settings, you might find that the section simply doesn't offer a direct option to extend the background color full-width, or perhaps it's styled in a way that makes direct changes tricky. This is where custom CSS becomes your best friend. Ploqo provided an elegant and effective CSS snippet that directly addresses this common theme quirk, especially prevalent in themes like Dawn.
This CSS trick works by essentially applying a massive, outward-extending box-shadow to the immediate children of your section and then using clip-path to hide everything outside the section's boundaries except for this new, wide background. It's a clever way to force a full-width background when the default options aren't cutting it.
Step-by-Step: Implementing the Custom CSS Fix
Here’s how to apply Ploqo’s custom CSS solution, complete with the visuals he shared, to get rid of those unwanted side strips and achieve a consistent background color:
Before: Darker strips at the sides

After: One pink all the way across

- Go to Online Store: From your Shopify admin, navigate to Online Store.
- Edit Your Theme: Click on Edit theme next to your current theme. This will open the theme editor.

- Select the Parent Section: In the left sidebar of the theme editor, locate and click on the Section that contains your problematic block (e.g., 'Two image cards'). It’s the parent element.

- Open Custom CSS: Scroll down in the section settings until you find the Custom CSS option and click to expand it.

- Paste the Code: In the Custom CSS box, paste the following code. Remember, the color
#fbeceeis what Tammy needed, but you can change this hex code to any color that matches your brand!> * { box-shadow: 0 0 0 100vmax #fbecee; clip-path: inset(0 -100vmax); }Don't worry if you see a yellow wavy line under the code; it's a common linter warning and won't prevent the code from working or saving.

- Save Your Changes: Finally, click the Save button in the top right corner to apply your custom CSS.

Ploqo confirmed this was tested on a Dawn store, so it's a solid fix for many of you using that popular theme or similar ones.
Why Community Insights Matter
This little challenge from Pretty Twinkles highlights something crucial: the power of the Shopify community. When you're building or migrating your store to Shopify, you're never truly alone. Questions like Tammy's, and the detailed, helpful responses from experts like alaattincagil and Ploqo, show how collaborative the ecosystem is. Sometimes, getting an expert to peek at your live site (as Moeed suggested, noting the need for a front-end password) can make all the difference in diagnosing trickier visual issues.
So, the next time you're facing a design puzzle on your Shopify store, remember these strategies. Start with the theme's built-in settings, and if those don't quite get you there, don't shy away from a little custom CSS. It can often be the exact magic touch you need to perfect your store's aesthetic and give your customers that polished, professional experience. Happy customizing!
