I don't know of a way of using logic (identifying a value in a tag and doing something particular) using just CSS and HTML, you'd need Javascript or some such for this. But if you're looking to hide the second p element in the text block you can do this using the nth-of-type CSS selector:
Wrap your p tags in a div and give the div a class.
<div class="HideChild"> <p>te</p> <p>st</p> <p>ing</p> </div> Then in your css create a selector like this:
.HideChild p:nth-of-type(2) { display: none; } Wrapping the p tags in a div and using a class means you can reuse this function for multiple text blocks on your page. If you want to change which line is hidden change the number after nth-child, and if you want the page to show a gap where the line should be replace display: none with visibility: hidden.
