html - Created horizontal list of image links that expand onhover. Lines appearing next to images onhover, why? -


live page, css source, page source

if hover on twitter icon, should see dark blue line appears right of icon disappears when move mouse off. happens icons except "donate" icon. suspect because icon blocks view of line, though guess mine. can tell me why mysterious line popping up? don't know how got there because using editor live page updates , assumed glitch.

thank you!

this should work you

a { text-decoration: none; }

by default text-decoration underline anchor tags.
