56. SRCSET is an attribute to the IMG element
<img alt="my awesome cat" src="image.png"
srcset="cat-hd.png 2x, cat-med.png 640w,
cat-med-hd.png 640w 2x" />
62. Don’t use a 💩 hosting provider*
and use a CDN to deliver assets
My old advice
* I still advise not using a 💩 hosting provider, but that’s not the point I’m trying to make right now
63. Use Cloudflare
• Significant speed increase with HTTP/2
• CDN for your entire site, not just assets
• Security and DDoS protection
My new advice
