Hi seanmcel
If you want to change the font globally, it's better to customize LESS file.
In case that you did not have variables.less file in local folder yet, you can copy the file: /templates/ja_sugite/less/variables.less
To: /templates/ja_sugite/local/less/variables.less
and edit this less file, you will see this declaration to change default font family, etc...
// Typography
// -------------------------
@font-family-sans-serif: "Raleway", sans-serif;
@font-family-serif: Georgia, "Times New Roman", Times, serif;
@font-family-monospace: Monaco, Menlo, Consolas, "Courier New", monospace;
@font-family-base: @font-family-sans-serif;
@font-size-base: 16px;
@font-size-large: ceil(@font-size-base * 1.25); // ~18px
@font-size-small: ceil(@font-size-base * 0.85); // ~12px
@font-size-h1: floor(@font-size-base * 3.125); // ~50px
@font-size-h2: floor(@font-size-base * 2.8); // ~45px
@font-size-h3: ceil(@font-size-base * 2.5); // ~40px
@font-size-h4: ceil(@font-size-base * 1.5); // ~24px
@font-size-h5: @font-size-base;
@font-size-h6: ceil(@font-size-base * 0.875); // ~14px
@line-height-base: 28 / unit(@font-size-base);
@line-height-computed: floor(@font-size-base * @line-height-base); // ~20px
@headings-font-family: inherit;
@headings-font-weight: 300;
@headings-line-height: 1.1;
@headings-color: inherit;
If you already purchased the custom service, you can ask team for help to update this, it would be quick.
But remember to backup your site first before changing.
