I would like to give you the recommendation to support you so kindly follow steps below:
Step 1: From your Shopify Admin, navigate Content section and select “File”.
Step 2: Upload your Font File by selecting “Upload file”.
Step 3: The opened window will allow you to select the font file to add. After having successfully uploaded the file, select the “Link” icon to copy the file link.
Step 4: After that, look for the file “theme.liquid” under the Layout section or via the search bar. Select to open the file.
Step 5: Add the following codes at the bottom of the file.
<style>
@font-face {
font-family: "GrandSlang-Roman";
src: url("Linkofthefontfile");
}
h1, h2, h3, span.marquee-text {
font-family: "GrandSlang-Roman" !important;
}
</style>
Replace the below elements of the code with actual data.
- Linkofthefontfile: the link of the Font File that was previously uploaded. It is copied after you select the Link icon.
Hit “Save” when finished.
So you can use FontName that you added.
If it still does not work, please send me the link of Font file that you uploaded to File folder so I can give the correct code for you.
I hope the above is useful to you.
