Iframes Aren’t Evil
Don’t fear the iframe.
I had gotten away in iframes in years past, but I’ve started to use them more on the blog, because they really are the best way to include maps, charts, and other content without having to override stylesheets. They also encourage caching and make coding much easier. Embeded iframes are totally hidden on modern browsers, and widely used on other social media platforms, including Youtube embeds.
