Pairing with Community Member Dan Ott

On , DEV Community member Dan Ott joined Christina and I on the pairing stream to work on a CSS issue related to Flexbox gap not being supported in Safari.

Here is the issue that we were working on:

`gap` doesn't work with `flex` on Safari #12452

Describe the bug

I've been living thinking that gap (as well as grid-gap) works perfectly fine with flex elements. Today I learned it's not supported in Safari which means there's a missing whitespace in Safari which I have already confirmed testing few views.

That means we have to fix all instances of a combination of two utility classes flex with gap-* in our views (.html.erb, .js, .jsx) AND also all instances of similar situation but in our SCSS files...

Yes, gap does work with grid but we should not simply replace every flex instance with grid because grid is for layout and flex is for components.

So in most cases we will have to remove gap property and replace it with additional margin on child elements...

To Reproduce

Test our site in Safari.

Desktop (please complete the following information):

  • Browser: Safari.

Smartphone (please complete the following information):

  • Browser: Safari

On this stream, we covered:

  • Replacing flexbox with CSS grid in certain areas of the site so that grid gap could be used
  • CSS grid features
  • How awesome CSS is

Thanks again for coming on the stream, Dan!
