Topic summary

A user seeks help customizing mobile navigation fonts in their Shopify theme. The solution involves editing CSS files (base.css, style.css, or theme.css) in the theme’s Assets folder.

Initial Changes:

  • Font size adjusted to 25px using .header-mobile__menu-main h6 selector
  • Later modified using span.h4.show-animate for different menu elements

Additional Customizations:

  • Text transform changed to lowercase using text-transform: lowercase; property
  • User inquires about changing font family to “Questrial Regular” (question remains unanswered)

Technical Approach:
All modifications follow the same workflow: Shopify admin → Online Store → Themes → Actions → Edit code → Assets folder → add CSS code → Save.

Screenshots demonstrate before/after results for each change. The discussion remains open with the font family question pending resolution.

Hi @ricky24

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:

.header-mobile__menu-main .h6 {
    font-size: 25px;
}

And Save.

Result:
