Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

-- This example is meant as a simple starting point to show how to get the information in the simplest available way.
-- Keep in mind that when asking for a `return` after another, only the first one will be output.
-- This method is as good as its JXA counterpart.

-- Webkit variants include "Safari", "Webkit", "Orion".
-- Specific editions are valid, including "Safari Technology Preview".
-- "Safari" Example:
tell application "Safari" to return name of front document

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

The State of Container Queries

tl;dr Developers would like the idea to style components based on a parent's width rather than depend solely on the viewport media query. This would allow modular components to style themselves while being agnostic to the viewport.

There is currently a lot of developer interest in getting a feature like Container Queries (née "Element Queryies") shipped in a browser.

2-min Catchup

Here are official'ish documents to outline the developer community's desires.
