Thanks to Claude, I was able to quickly fix two minor annoyances I was having with Flickr and YouTube short URLs in posts here.
One convenience of WordPress is its built-in handling of straight URLs from those two platforms. Just pop the URL in to its own line in your post, and voilà! you have your photo or video embedded with no additional coding on your part.
I decided I wanted to change the width of content displayed (notably on desktop), which thanks to the Twentig plug-in was a simple click. However, doing so meant those embeds were no longer behaving how they were previously under the default, narrow content view. Not to mention some of the Flickr embeds had never been full width. Claude helped with some additional CSS I then added to the theme, and it’s looking just how I want it. Which may not matter to anyone else, but it matters to me, so there we go.
Having fixed this, I’m now tempted to go back and fix a lot of posts where I uploaded images to my WordPress Media Library when I could just be linking to the images on Flickr and saving the storage. Will have to give that some thought.
