You might know Filestack from being an incredible service to add file uploading, storage, and management to your own web apps.

There is another thing Filestack can do for you: convert documents into different formats.

For one thing, it can manipulate documents. Take images. Perhaps you would like to offer some image manipulation for your users uploaded images, like cropping and rotation. That’s a common feature for apps that offer avatar uploading. With Filestack, you got it.

It’s great …

Yes, this is a React component, but regardless if you care about that part or not, the “ideal image component” part could be of interest. There is a lot to consider with how we put images on web pages these days. This deals with:

• Placeholder space (and then flexible responsive styles after loading)
• Low-quality placeholder images
• Responsive images syntax (srcset)
• Image formats (e.g. using WebP when you can)
• Click-to-load on bad network connections
• Better UX for loading errors,

When we produce a PNG image, we use an <img> tag or a CSS background, and that’s about it. It is dead simple and guaranteed to work.

You don’t have to inline the SVG if you don’t want. It could be an <img> or background-image as well.…

A good candidate for the Blog Post of the Year from Zach Holman. I think Eric Portis’ “w descriptors and sizes: Under the hood” is up there too, but perhaps even nerdier. Ooooh, also Frank Chimero’s “The Good Room” is up there. But I digress.

Zach’s article is as educational as it is funny.

But yeah, this UTC initialism doesn’t make any sense. Let’s dig into this a little more.

This isn’t a comprehensive guide to centering things. We have that!

This is just a little observation about old and new. One of the trickier things related to centering in CSS is when you need to center both vertically and horizontally and you don’t know the width or height of what you are centering. Vertical centering being the extra tricky of the two.

Believe it or not, there was a way to do that even in IE 8. The trick …
