Make the collection list full width in impulse theme?

Topic summary

A user seeks to make a collection list display at full width (without side padding) on both desktop and mobile in the Impulse theme.

Initial Troubleshooting:

  • Standard theme customization options (“Full page width” checkbox) are not available for this particular section.
  • Attempts to modify .page-width CSS globally affected the entire store layout unintentionally.

CSS Solutions Attempted:

  • Adding .collection-content .page-width { max-width: 100%; } to theme.css
  • Fixing extra closing brackets that caused syntax errors
  • Targeting specific section ID with #shopify-section-template--16125451993296__featured-collections .page-width { max-width: 100% !important; }

Outcome:

  • Despite multiple CSS iterations and cache clearing, changes did not render correctly on the user’s end.
  • Eventually, the original poster experimented independently with different code variations and achieved success.
  • Another participant confirmed the same goal is achievable, referencing a working example site.

Status: Resolved through self-experimentation after guided CSS attempts.

I’ve been trying to figure out how to make the list full screen on both desktop and mobile view and im not able to. I don’t want the padding on the sides. Can someone help?

Some sections have an option for full page width. go to

Online Store > Themes > Customize

there you can see all the sections of your home page. click on them and the options for each on shows up on the right. some sections will have a check box “Full page width” and also have a check box “Add spacing above and below”

Thanks for the quick reply. I tried already. That section doesn’t have the full width option.

can you post a link to your site?

in your theme.css file there is

.page-width {
max-width: 1500px;
margin: 0 auto;
}

remove the

max-width: 1500px;

It affected the whole store layout. There’s no way of fixing just that section?

yes there is. put back what you did before

and add the follwoing to the end of your theme.css

.collection-content .page-width {
max-width: 100%;
}

let me knoo if this works

it didn’t. :sob:

do you still have the code there so i can see what wrong?

you have this at the end of your CSS file

.label, label:not(.variant__button-label):not(.text-label) {
    letter-spacing: .04em;
    font-size: 0.90em;
}
}
.collection-content .page-width { max-width: 100%; }
}

there are too many closing bracks " } "

i think it need to looke like this

.label, label:not(.variant__button-label):not(.text-label) {
    letter-spacing: .04em;
    font-size: 0.90em;
}
.collection-content .page-width { max-width: 100%; }

you have 2 extra clsoing brackets.

I just erased the unnecessary brackets and it still doesn’t work.

can you please post here a screen shot of the end of the file.

can you please get in as much lines as you could.

@Tesoro i think we took out a bracket that should have stayed in there. can you add in a bracket like this.

and then send me a screen shot

I added another bracket but still not luck.

it works, you gotta refresh your cache. or open it up in a new browser or incognito

I tried everything you said and it doesn’t look like it on my end :disappointed_face:

no worries. can you send me a full screen shot of what you are seeing?

also can you go here and tell me you browser size http://howbigismybrowser.com/

what type of browser are you using?
