Adding custom CSS and JS to Shopify

Question

I am working on getting vertical tabs for a page on Shopify, using the \'Atlantic\' theme. As this theme does not have vertical tabs by default, I have used the external JS

Answer 1

Simply upload your filename.js file in the assets folder.

then drop the following in your theme.liquid head section:

{{ 'filename.js' | asset_url | script_tag }}

by the way, you should rename your file and add .liquid extension

filename.js.liquid

Good luck!

Answer 2

Open theme.liquid and check how the css and js are included and add yours by following them.Add your custom file to assets.Css And Js Add Image attached

Answer 3

If you don't want to pollute the global namespace you can restrict the JavaScript or CSS to certain areas.

Shopify uses a simple if statement together with the page-handle for that(for www.foo.com/abcd/bar - "bar" would be the handle).

{% if page.handle == "bar" %}
    {{ 'your_custom_javascript.js' | asset_url | script_tag }}
    {{ 'your_custom_css.css' | asset_url | stylesheet_tag }}
{% endif %} 

This is extremely useful if you want to make smaller changes to certain pages.

Answer 4

For JS files, never create the file directly via Shopifys "Create a blank file"-dialogue. Instead, create the file locally as .js (not .js.liquid), then upload to the assets folder.

You can then simply reference the file in the theme.liquid head section:

{{ 'filename.js' | asset_url | script_tag }}

Background:

It seems that Shopify always sets the mime type to text/x-liquid when creating new files and if liquid is used for the theme, regardless of the file extension. This will then result in a browser error like this one from Chrome:

Refused to apply style from ... because its MIME type ('text/x-liquid') is not a supported stylesheet MIME type, and strict MIME checking is enabled

Answer 5

If I understand correctly, the asset_url filter is what you are looking for.

To include a JS file in a .liquid file, you use:

{{ 'script.js' | asset_url | script_tag }}

And a CSS file:

{{ 'style.css' | asset_url | stylesheet_tag }}
