For anyone who has experience in building WordPress themes – or even just one theme – or anyone who has experience in working with child themes, or simply modifying a core theme, then you’re more than likely with <a title="wp_title" href="http://codex.wordpress.org/Function_Reference/wp_title" target="_blank">wp_title</a>.
It’s one of the tags in WordPress that’s easy to usd and that’s easy to understand. Straight from the Codex:
Displays or returns the title of the page. A separator string can be defined, and …, that separator can be designated to print before or after the title of the page.
This tag can be used anywhere within a template as long as it’s outside The Loop on the main page, though is typically used in the <title> element for the head of a page.
Not much to it, right?
But it’s also one of the tags that can be abused which can cause problems especially as it relates to plugins.
