Full width/height image banner for collections - DAWN THEME

Topic summary

A user wants to create a full-width/height image banner on collection pages in Dawn theme 6.0.2 that covers the header area.

Initial Solution Attempted:

  • Another user provided CSS code to add to base.css, including adjustments for banner min-height and footer form positioning
  • This solution did not work as intended

Partial Success:

  • The original poster found a workaround by adding code to template-collection.css that achieved the full-width banner effect

New Issues Created:

  • Product page images and descriptions now overlap with the header
  • Main menu alignment with the logo is broken

Hi There,

Thank you for reaching out to the Shopify forums!

Let me quickly fix that issue for you.

Please add below CSS in your base.css file.

@media screen and (min-width: 750px) {
.banner--small:not(.banner--adapt) {
    min-height: 80rem;
}
}

#FooterCountryForm {
    position: absolute;
    top: 30px;
    left: 0px;
}
#FooterLanguageForm {
    position: absolute;
    top: 30px;
    left: 9%;
}

@media screen and(max-width: 992px) {
#FooterLanguageForm {
    position: absolute;
    top: 30px;
    left: 17%;
}
}

@media screen and(max-width: 992px) {
#FooterCountryForm {
    position: static;
}
#FooterLanguageForm {
    position: static;
    top: 30px;
    left: 17%;
}
}

If its working then, please do not forget to accept this solution :face_savoring_food:

Hi Prezentech!

Thank you very much for trying to help.

It’s not really working unfortunately.

However with the bellow code added to template-collection.css, I managed to do it.

But now I have a few issues with the product pages, 1) the image & desc completely overlap with the header and 2) the main menu is not aligned with the logo anymore…

#shopify-section-header {

  margin-bottom: -100%;

}

.header-wrapper {

  background: none!important;

}
