I see a lot of websites/blogs and a lot of them are running WordPress. Sometimes I see a blog with a theme that looks familiar… as if someone took a standard theme freely available online and just tweaked it a bit. Inevitably one of those “tweaks” is to take the credit of the original theme creator out of the footer (where it usually lives). However, most people stop there when it comes to removing the original theme branding so a quick peek at the HTML source can reveal the original theme.
In Firefox head up the to “View” menu and choose “Page Source.” Next, toward the top of the HTML look for a line that looks something like this:
<link rel="stylesheet" type="text/css" href="http://website.com/ wp-content/themes/THEME_NAME_HERE/style.css" />
Except, instead of THEME_NAME_HERE you will probably see the name of the original theme. Now you can do a quick search for that theme and see how much (or little) the blog owner actually modified from the original. It really is that easy.
