Action:

Ensure that the form is wider on smaller screens or with higher zoom levels

DEV-480 On 320px screens, slug field in element slideout can no longer be seen or edited

Where: Element edit slideout

The slug field value goes to 0px width on small/zoomed screens

The CSS dynamically calculates this width to be 100% minus a set px value, which ends up falling below zero at this screen size. The CSS should be modified to account for smaller screen sizes

@gcamacho079 Is there a reason you went with 600px for this?

I was thinking it would be good to move Slideout.js::useMobileStyles() to Craft.js so we can use it for other things as well. But it would be good to be consistent about what we consider a “mobile width”.

Looking through the CSS media queries, looks like the smallest viewport size we check for currently is 500px, when determining whether 25/50%-width fields can be displayed side-by-side:

https://github.com/craftcms/cms/blob/1c7f4ee60f10ffc896534a126068f72b1d04eeca/src/web/assets/cp/src/css/_cp.scss#L1585-L1591

Do you think we should change that media query to start at 600px, or drop the useMobileStyles() check down to 500px?

@brandonkelly My rationale here was that at 500px wide, the slideout is only about 250px wide. When I was testing in responsive design mode, 300px seemed like a comfortable minimum width for it.

We could always have the useMobileStyles function use a default parameter of screenWidth = 600, and just override it for the slideout in particular. Or we can stick to 500px across the board 🤔
