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

If you want to use travis_retry from within your own shell script files then you first have to make the travis_retry shell function available by sourcing the travis_retry.sh file, otherwise you just get a "command not found" error. See example.sh for a full example.

Note that the original function as found in the travis-ci/travis-build repository was slightly modified to allow it to be used in a shell context where set -e is enabled.

For reference, a tweet by Travis CI saying that you should copy the travis_retry code as I've done here: https://twitter.com/plexus/status/499194992632811520
