# Michael Irigoyen - Stop Using Icon Fonts (Highlights) ![rw-book-cover|256](https://readwise-assets.s3.amazonaws.com/static/images/article1.be68295a7e40.png) ## Highlights - While waiting for the font asset, the browser will choose to display the textual content of the HTML before actually receiving it. This results in a flash of unstyled content (FOUC). ### To fully support the use of SVGs on your site, make sure you're following other common best practices - Optimize your SVGs — Run your SVG images through an optimizer to get the size down. - Enable Compression — Configure your server to send all textual assets (HTML, JS, CSS) with Brotli (or GZIP). - Cache effectively — Set appropriate caching headers so your visitors only download things as they change.
