Detecting Specific Text Input with HTML and CSS

Recently I came across a CodePen demo by a developer/engineer named Jane that was Tweeted out by Šime Vidas. The demo has a neat collection of HTML and CSS tricks rolled into one that I thought was worth examining in detail.

The page displays a secret message based on specific text input. Ok, that’s no big deal, right? Well this is done using pure HTML and CSS – no JavaScript. I’ve seen stuff like this before, but I thought it would be cool to break down exactly how this works. There are a few notable things happening in the code so I’ll break down each of the parts.

The post Detecting Specific Text Input with HTML and CSS appeared first on Impressive Webs.
