Enhancing Your Mobile View: Adding a Line Under the Header in Shopify's Publisher Theme

Once upon a time, in a land not unlike our own—I mean, right here in our trusty Shopify kingdom—I stumbled upon a curious conundrum. There we were, scrolling through our sleek, shiny online store, proud of how it dazzled on desktops. But wait! A napkin suddenly flew out of nowhere with a shocking revelation: the mobile view looked rather naked without the elegant line under the header it boasted on larger screens.

That was when I, with a mighty spurt of determination, embarked on a quest. Together, let's unravel this challenge.

Defining the Gap: The Desktop vs. Mobile

Let’s clear the fog first. You know the code that brings that satisfying line to life on desktops? It's like having a well-cut suit for the meeting while wearing pajamas for the same in mobile view.

The code that’s getting all the desktop attention looks like this:

@media screen and (min-width: 990px) {
  .header:not(.drawer-menu).page-width {
    border-bottom: 1px solid;
    max-width: 100% !important;
  }
  .scrolled-past-header .header:not(.drawer-menu).page-width {
    border-bottom: 1px solid #fff;
  }
}

I could almost hear the mobile view crying out, “What about me?” So how do we extend this love?

Crafting the Code for Mobile Magic

Remember when Aunt Susan wrapped gifts perfectly, leaving us in awe? Well, adding a line for the mobile header is like that, but with CSS.

Here’s the spell we need:

Open the Theme Code Editor: First, go to your Shopify admin and navigate to 'Online Store.' Hit 'Themes,' and then the little three-dot button next to 'Customize.' Click 'Edit code,' and we're in!
Locate theme.css or styles.css: This is where the magic happens. It’s like finding the right page in Aunt Susan's cookbook.
Add Mobile View Code: Scroll to the bottom of this CSS file—think of it as the appendix—and consider adding the following snappy code:

@media screen and (max-width: 989px) {
  .header:not(.drawer-menu).page-width {
    border-bottom: 1px solid #000; /* You can change the color to whatever you like! */
  }
}

Save & Preview: Click that lovely ‘Save’ button, then peek at your store in mobile view. Much like a magician eagerly inspecting the rabbit from his hat, see if the line under the header appears as it should.

Behind the Scenes: Tweaking and Tailoring

Ah, customization! If your store were a person, this is where it starts wearing shades indoors. Maybe you want that line a little thicker? Or maybe a dash of color beyond plain ol’ black or white? Here's how you charm CSS beyond basics:

Change Thickness: Play around with border-bottom: 2px solid; for a thicker line.
Color Play: Swap #000 in border-bottom: 1px solid #000; with a personal shade. #FF5733 perhaps? Go wild.
Spacing Harmony: If things feel too cozy, try adding padding-bottom: 10px; inside your mobile CSS block to give that line some breathing room.

Feeling the Joy of Success

With the digital flourish achieved, our mobile view now rejoices—standing proud with a line that’s both stylish and functional. It’s a thing of beauty, isn't it? It's like when you finally clean out that junk drawer and find the treasure of lost keys and mystery cables.

Reflecting on the Journey

Creating this small, yet impactful, touch is a reminder of the satisfying details in web crafting. It takes me back to those shared discoveries with my brothers when fixing up our first bicycle. The clink of the chain mirroring the click of the mouse, and there’s just a rush you can't compare.

Through our digital maneuvers, such as this little CSS tweak, we better our store aesthetics and grow closer—both as builders and benefactors of our own creations. Cheers to our ongoing adventure with Shopify, line by line, and pixel by pixel.

So, comrades, let’s keep our sails high and our mobile headers lined as we continue this wondrous expedition in the e-commerce seas!
