Every once in a while i run into this crazy issue. I have an image inside a link like so:
I am trying to add a caption with a background color on top of the image, but for some reason there is an extra 4px or so at the bottom that doesn’t come from any css that i use.
To get rid of the problem I finally found a post on stackoverflow that helped me fix it.
You just assign the img this css
That fixes it.
