 @import url('');

Fixing Local Web Fonts

If you are using @font-face and the fonts files are located in your server then you can use the following.

@font-face {
  font-family: "Open Sans Regular";
  font-weight: 400;
  font-style: normal;
  src: url("fonts/OpenSans-Regular.woff2") format("woff2");
  font-display: swap;

What exactly the font-display does?

font-display is a CSS property which is available in most of the latest updated browsers. font-display is used inside of a @font-face. When we set the font-display:swap, upon initial page load the system default fonts are swapped unless the custom fonts or google fonts are loaded. This helps user to read the content immediately.
