A user is attempting to optimize the vertical layout of product add-ons on a Shopify product page by repositioning text labels, prices, and dropdown menus into a more compact horizontal arrangement.
Solution Provided:
A CSS solution using Flexbox was shared to align add-on elements horizontally:
Initial code aligned items in a single row with flexible wrapping
Additional refinements addressed dropdown width limitations and spacing issues
Final working CSS includes display: flex, flex-wrap: wrap, gap: 1rem, and max-width: 25em for select elements
Key Technical Issue:
The user encountered a syntax error (gap: 1 rem instead of gap: 1rem - no space between number and unit), which was corrected.
Ongoing Problem:
The Shopify theme customizer’s “Custom CSS” field is malfunctioning - it constantly refreshes during typing and won’t allow saving changes despite valid CSS syntax. The workaround of preparing code externally and pasting hasn’t resolved the save issue. The layout now displays correctly in preview but cannot be published due to this editor limitation.

The issue shown in the image is caused by the current layout placing each product add-on (title, price, and select option) in separate vertical blocks, leading to excessive vertical space usage on the product page. This happens due to the use of block-level elements and default CSS styling. To fix it, you should restructure the HTML using a horizontal layout with Flexbox, which aligns the add-on label, price, and dropdown in a single row, minimizing vertical space and creating a cleaner, more compact display.
I am pretty tech savvy, but CSS is very new to me. I put your code into the custom CSS field for the product page and it definitely helped! For some reason only one of the drop-downs changed. Any ideas? I’m guessing that it could have to do with the length of the text in that drop-down being longer, causing an overflow and the line to wrap. Is that right?
The “custom CSS” field in the “customization” editor, is really giving me fits. It is constantly refreshing the page while I try to type, which makes it nearly impossible to edit CSS there. If I prepare the code in notepad and paste it over, it takes effect (and no syntax errors shown) but the save icon is greyed out, so I can’t push the changes. Any idea on that? I tried clearing all site data, and even working in an incognito window.
