Navigation and Resource Timing provides timing data for the fetch, but currently there is no interoperable way for the server to communicate own timing information to the client. For example:

What steps were taken to generate the resource, and how long each took. Many sites already embed this type of information via HTML comments - e.g. wordpress emits  , and many sites provide more detailed stats (cache, db, generation) to enable performance debugging.
If proxied, where was the time spent - e.g. time to fetch from origin, time to process response, etc.

Instead of relying on arbitrary HTML comments, we can define an HTTP header that can be used to send key-value pairs in a well defined format. Making this data available via a well defined interface would...

Allow UA and other developer tools to automatically annotate appropriate timelines.
Allow analytics vendors to gather this data for operational analysis.
Allows proxies and CDNs to append custom timing d

CSS Layout Debugger

A tweet-sized debugger for visualizing your CSS layouts. Outlines every DOM element on your page a random (valid) CSS hex color.

One-line version to paste in your DevTools

Use $$ if your browser aliases it:

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!
