How can I add white lines to my header menu drawer?

Topic summary

A user seeks help adding white horizontal lines to their header menu drawer, similar to a reference image they provided. They shared their store URL (matibrnd.com) and example screenshots.

Solutions offered:

  • topnewyork suggested adding CSS code to the base.css file targeting menu drawer items with text-decoration: underline
  • HM_Helal recommended inserting CSS code into theme.liquid above the tag

Current status:

The user responded that the solution is “almost” working but needs adjustment—they want the lines to extend all the way to the right edge, referencing “thehundreds” as an example. They provided an additional screenshot showing the desired result.

The discussion remains open with the user awaiting a refinement to make the underlines span the full width of the menu items.

a.menu-drawer__menu-item.list-menu__item.link.link--text.focus-inset{
