Hi Vance,
Katy here from Shopify! Welcome to our Forum community and thanks for your query.
I’d love to help you out with this here. As it will need a little bit of editing to your theme’s code, so I do suggest that you do this first in a duplicate version of your theme. Info on how to do so here, just in case.
Great job on already uploading the image to your assets folder! (For anyone else who may stumble upon this post, we have a guide to help with this here).
Once you have this done, you will then need to paste the following code at the bottom of your theme.scss.liquid. We add this at the bottom, as it reads in a cascading fashion. If you could scroll down to the very bottom of this sheet and add the following:
.password-page {
background-image: url({{ 'image.jpg' | asset_img_url: '2000x' }});
}
To make your image cover the entire container, you can also add this line of code beneath this rule also:
background-size: cover;
I’m not sure how you would like the image to display, but if you find that the width of the image is being constrained or you would like to set this as full screen for example, you would then need to remove the page-width class from the containing div.
To do this, if you could go to password.liquid under ‘Layout’ and search for this line. (It should be located somewhere around 40/41, depending on if you have made edits to this yet or not).
`<div class="password-page page-width text-center" role="main">`
You can then swap this for the following line instead:
`<div class="password-page text-center" role="main">`
I do hope this helps- do feel free to let me know how you get on, or if you have any questions.
There are also some handy resources on customizing your password page within our Shopify Blog here too.
Cheers,
Katy
