A Couple Changes Coming in Chrome 108

• The object-fit property is used to scale the image and fill the box. If the aspect ratio does not match the box, the image will draw outside of the bounds.
• The border-radius property makes a square image look like a circle, but because overflow is visble the clipping no longer occurs.
• Setting inherit: all and causing all properties to inherit, including overflow.

Worth reading the full article for code examples, but the solution for unwanted visible overflow is overriding the UA’s default overflow: visible with overflow: clip:

img {
  overflow: clip;
}

“Prepare for viewport resize behavior changes coming to Chrome on Android”:

In November, with the release of Chrome 108, Chrome will make some changes to how the Layout Viewport behaves when the on-screen keyboard (OSK) gets shown. With this change, Chrome on Android will no longer resize the Layout Viewport, and instead resize only the Visual Viewport. This will bring Chrome on Android’s behavior up to par with that of Chrome on iOS and Safari on iOS.

This is a change related to the common headaches of working with viewport units and fixed positioning on mobile touch devices. We’ve covered (and tried solving) it over the years:

• “Some Things You Oughta Know When Working with Viewport Units” (Chris Coyier)
• “The trick to viewport units on mobile” (Louis Hoebregts)
• “The Large, Small, and Dynamic Viewports” (Chris Coyier)
• “CSS fix for 100vh in mobile WebKit” (Chris Coyier)

The change means that Chrome on Android will no longer resize the Layout Viewport when the on-screen keyboard is shown. So, the computed values of viewport units will no longer shrink when a device’s keyboard is displayed. Same goes for elements that are designed to take up the full viewport no longer shrinking to accomodate the keyboard. And no longer will a fixed-position element wind up who knows where when the keyboard pops up.

This brings more consistent cross-browser behavior that is on line with Chrome, Safari, and Edge on iOS and iPadOS. That’s great, even if the updated behavior is less than ideal because the keyboard UI can still cover and obscure elements that get in its way.

If you prefer elements to remain visible when that happens, it’s worth looking at a solution Chris shared a long while back that uses the prefixed webkit-fill-available property:

body {
  min-height: 100vh;
  min-height: -webkit-fill-available;
}
html {
  height: -webkit-fill-available;
}

That uses the available space in the viewport rather than what’s covered by the UI… but Chrome currently ignores the property, and I’d bet the nickel in my pocket that it is unlikely to start respecting it in the 108 release. That may be a moot point, though, as Chrome 108 also introduces support for small, large, and dynamic viewport units, which are already supported in Safari and Firefox.
