Several Webflow sites I have built in the past where they are icon heavy suffer from too many HTTP requests. When adding an SVG as an image it creates an http request for each one.
My solution to this is using SVG sprites, I do this by creating an embed for each icon eg:
<svg viewBox="0 0 100 100" class="icon pencil"> <use xlink:href="#shape-codepen"></use></svg>
Unfortunately this is hard to implement in Webflow for 2 main reasons.
This means no way to have a menu with svg use icons inside it.
