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

Ubuntu 16 – how to increase maximum file open limit ( ulimit -n )

If you are setting up nginx,chances are you will discover your worker_connections is at some low number, such as 1024. You can’t increase this number unless you increase kernel limit as well. First of all run cat /proc/sys/fs/file-max to discover your maximum limit.

abc@ubuntu:~$ cat /proc/sys/fs/file-max

How to test NVDA screen reader behaviour on a Mac:

1. Download Microsoft Edge VM from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
2. Download Virtualbox and import the Edge VM image.

Then in the VM:

1. Install guest addons in the VM
2. Download & install latest NVDA from nvaccess.org
3. Download & install SharpKeys and use it to map left an alternative key (eg. Left Ctrl) to the Insert key. This is needed because Macs do not typically have an “Insert” key which is the prefix for many NVDA commands.
