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.
elem.offsetLeft
, elem.offsetTop
, elem.offsetWidth
, elem.offsetHeight
, elem.offsetParent
SSH into your EC2 instance. Run the following:
$ sudo yum install gcc
This may return an "already installed" message. That's OK.
$ wget http://download.redis.io/redis-stable.tar.gz && tar xvzf redis-stable.tar.gz && cd redis-stable && make

/** | |
* For modern browsers | |
* 1. The space content is one way to avoid an Opera bug when the | |
* contenteditable attribute is included anywhere else in the document. | |
* Otherwise it causes space to appear at the top and bottom of elements | |
* that are clearfixed. | |
* 2. The use of `table` rather than `block` is only necessary if using | |
* `:before` to contain the top-margins of child elements. |
