The best thing to do when developing the look and feel of a site is to right click an element on the page near where you want to modify and clicking "Inspect" from the right click menu (that's the same menu you'd use if you wanted to save an image, but it's at the bottom). This works in both Chrome and Firefox. What you get is a view of the HTML source and, on the side, any CSS properties directly related to that element. You can make edits here and they will update live on the screen! But these are not real or permanent changes - so when you're done playing around, remember to add your new additions and edits to your site's real CSS file.
You might consider adding in a CSS property called "
vertical-align", modifying the line-height for the text, or making all images in that element move by shifting their margins (which can be negative values, too).
