Sitespeed.io - Performance reports of your site

By K -

Today Andrzej Maciurzyński @ajumac send me link to really nice tool to check good practices of websites from your backend. Testing within browser is great but you can't easily share result within a team or make it part of build or continuous integration process.

With http://sitespeed.io/ using Phantom.js you can generate performance results of your page and publish it next to your site. This can be really useful to see if your last commit make something slower.

First how to reproduce it: Open  http://krzychukula.github.io/vw_bfcache/  in Mobile Safari.  Click "Go to another page" link Leave phone for 60 seconds (longer is better) Click back button If you were lucky you should see some missing paragraphs and missing green boxes. How it looks: Bug: This one uses vw and vh for font-size. Both are 0 so we can see only 2 from 8 paragraphs. Those two are using only em for font-size. I was curious if it's only for font-size so I have added another test. I have added two boxes with width and height set in vw and vh with green background color. They parents have red background for contrast.  Most of t
