As anyone who has tried to validate a website to a Strict doctype knows, the
target="_blank" attribute is no longer allowed. The most common question is Why? and there is a simple answer.
The absolute best solution I’ve seen to this utilizes the
rel attribute of the <a> tag, and turns…
<a href=”document.html” target=”_blank”>external link</a>
<a href=”document.html” rel=”external”>external link</a>
Perhaps in the future, when more and more people are using browsers with better tabbing abilities and auto-tab-opening of off-site links, this won’t be an issue anymore. For now, this is a solution.
