Hi @matthu
If you are looking to load Roboto font, Then you no need to upload a web file because the portal is already loaded with some of the most used google fonts.
Here are the steps for you.
In Portal Studio:
1. Upload a "Custom.css" File
2. Add the following code in the custom.css file
body, html, h1, h2, h3, h4, h5, h6, .h1, .h2, .h3, .h4, .h5, .h6 {
font-family: "Roboto" !important;
}
.navbar-static-top.navbar .menu-bar > .navbar-nav > li > a {
font-family: "Roboto" !important;
}
3. Hit save and press sync configuration. Browse the website > Ctrl + F5

Output:


Hope it helps.
