Patch Redactor to allow header formatting

For whatever reason Redactor in older versions does not allow formatting to be applied to headers. After some Googling I was able to find a solution posted by Simon on StackOverflow. It turns out you can comment out one of the lines that guard against this and it works!

Create a play button overlay with a pseudo-element

Today I learned how to create a play button overlay on a video thumbnail. .placeholder-video { position: relative; width: 854px; height: 480px; } .placeholder-video img { width: 854px; height: 480px; padding: 0px; } .placeholder-video:before { content: ''; position: absolute; display: block; width: 100%; height: 100%; background-size: 100%; background-repeat: no-repeat; background-position: center; background-image: url("/images/play_button_overlay.jpg"); opacity: .50; } .placeholder-video:hover:before { opacity: .55; }
