Change color/boldness of specific header item

Topic summary

Goal: make the “BUNDLES” item under the SHOP navigation red and bolder.

  • Suggested approach: add custom CSS in the theme (via Shopify Admin > Edit theme code) to style the specific dropdown menu item with color: red and font-weight: bold. CSS is the site’s styling code; base.css is a common stylesheet file in many themes.
  • Complication: the theme did not have base.css. The change was implemented elsewhere in the theme files, but initially did not appear on mobile.
  • Outcome: the styling was later confirmed as working, with screenshots showing the red, bold “BUNDLES” entry.

Attachments: screenshots were central to confirming the visual result.

Status: resolved; no further action items noted.

Hi, our site is www.uncertn.com

I want to change the “BUNDLES” text under the SHOP navigation to red and increase the boldness.

Hello @UCJustin

In Shopify Admin, you can go to Edit theme code, open file base.css and add this code at the bottom

.dropdown__family:last-child .navtext {
color: red;
font-weight: bold
}

The result

Hope it helps!

Hi! Our theme doesn’t have base.css.

Looks like I got it to work but it’s not showing on mobile?

Looks like it is working correctly now!
