A CSS trick to show before or after pseudoclass in a hidden div
Today I had to do figure out a way to show an automatic message on a hidden div (which had display: hidden), so the idea was that the user would see a message and after clicking on a button, the message would be removed and in its place the hidden div would be shown.
A found a tricky solution:
instead of using display: hidden, in which case, the before pseudoclass would be hidden as well, why not use a negative text-indent approach? And it worked!
You can take a look to my codepen below, but the trick is more or less simply:
<iframe height="800" style="width: 100%;" scrolling="no" title="Showing the before pseudo-class of a hidden div " src="https://codepen.io/albertofortes/embed/oNXYgOy?height=265&theme-id=default&default-tab=css,result" frameborder="no" allowtransparency="true" allowfullscreen="true"> See the Pen <a href='https://codepen.io/albertofortes/pen/oNXYgOy'>Showing the before pseudo-class of a hidden div </a> by Alberto Fortes (<a href='https://codepen.io/albertofortes'>@albertofortes</a>) on <a href='https://codepen.io'>CodePen</a>. </iframe>
