Editing "line-height" caption

Hello,

I changed the line-height property (style.css) of gallery caption successfully, but now I want to edit the same property of the rest of images

I tried editing .wp-caption class and .wp-caption-text (in style.css) but as you see in the image there is no change. I think its a problem with the <span> tag, is set to “line-height: 26px;” in style.css
