Idea for this post came because my blog’s new theme had borders over all smileys which looked a bit odd. So I thought why not make a post about it.
Open your theme’s style.css file and add this in last line:
[css light=”true”]img.wp-smiley{ border:none;}[/css]
That’s all. Nothing more. It will remove borders on all smileys and works with all themes in wordpress and for most versions of wordpress.
