Specificationhttps://drafts.csswg.org/css-sizing-4/#sizing-values Summary A keyword for CSS sizing properties (e.g. 'width', 'height') that allows elements to grow to exactly fill their containing block's available space. It is similar to '100%', except the resulting size is applied to the element's margin box instead of the box indicated by 'box-sizing'. Using this keyword allows the element to keep its margins while still being as large as possible. Essentially an unprefixed version of '-webkit-fill-available'. Blink componentBlink>Layout <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3ELayout> Motivation To get this behavior without this new property you have to jump through hoops. You can use align/justify-self:stretch, but then you can't use align/justify-self to actually align the element. Also, not all layout modes support align/justify-self in both the inline and block directions. Alternatively, in many situations but not all, you can use a variable to store the element's margins and refer to the variable in both the margin and sizing properties, like height:calc(100% - var(--my-margin)). That's clearly a hassle.

Lots of +1 on the chrome bug. *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?
