A transparent background would look exactly as it does now. If what you mean is that you want to "blur" the image so that the text is easier to read, the you can enclose your text in span tags and apply a translucent background using the rgba function.

Just FYI, it looks like your site CSS uses variables. Just in case you weren't aware, variables weren't widely supported until about 3 years ago. So your variable-based styling won't work for anyone with a browser older than that (ex. Internet Explorer). It is up to you guys whether or not your care; most people don't.
