How to get 3 Multicolumns on One Line for Mobile

Store Design
,

Topic summary

A user is trying to display three multicolumn disclaimers in a single horizontal row on mobile devices, but they currently appear stacked across two lines, pushing product content down the page.

Initial Solution Provided:

  • Add CSS media queries to base.css, style.css, or theme.css
  • Target .grid--3-col-tablet-down .grid__item and .multicolumn__card_info with specific width and padding adjustments
  • Code includes breakpoints at max-width 640px and 500px

Outcome:

  • Initial CSS addition to base.css partially resolved the issue
  • Problem persisted on Pixel 6 phones (which don’t have the largest screens)
  • User discovered their theme uses theme.css.liquid instead
  • Adding the code to theme.css.liquid successfully fixed the display issue

Status: Resolved. The three-column layout now displays correctly on mobile after applying CSS to the correct theme file.

I need help to get all 3 multicolumns for mobile on one line. Right now, every tweak I make for the mobile version always show the columns on 2 lines.

The site I am working on needs the 3 disclaimers at the top which is pushing down the products below the fold on mobile.

Here is a screenshot of the mobile site with the 3 columns on two lines.

Hi @TechNewbie

Check this one.

From your Shopify admin dashboard, click on “Online Store” and then “Themes”.

Find the theme that you want to edit and click on “Actions” and then “Edit code”.

In the “Assets” folder, click on “base.css, style.css or theme.css” file, depending on which file your theme uses to store its CSS styles. At the bottom of the file, add the following CSS code:

@media screen and (max-width: 640px){
.grid--3-col-tablet-down .grid__item {
    width: 30%;
}
    }
@media screen and (max-width: 500px){
.multicolumn-card__info {
    padding: .5rem;
}
}

And Save.

Result:

Thanks for your help.

I edited the base.css. The code improved the issue. But I have a Pixel 6 phone which doesn’t have the biggest screen. It is still showing the 3 columns on 2 lines.

After more digging I see I have theme.css.liquid. Adding the code there fixed the issue.

Thanks.
