CSS - images and replaced content

By far the most important part of Images and Replaced Content is gradients. Still, there are a few other interesting properties.

This is the mobile table. See also the desktop table.

Last major update on 26 November 2014.

If you want to study gradients, start with the Introduction to gradients.

This entry states if the browser supports either unprefixed new syntax or -webkit-prefixed middle syntax. If the browser does not support the example below on this page it gets a No here and I don’t investigate it any further. Puffin loads the gradients as if they are images, and slow ones at that.

This entry states if the browser supports either unprefixed new syntax or -webkit-prefixed middle syntax. If the browser does not support the example below on this page it gets a No here and I don’t investigate it any further. Android 4.0 doesn’t support `ellipse`; only `circle`. If you explicitly define `circle` everything is fine, but if you don’t it uses circles nonetheless and does other things wrong, too. Puffin loads the gradients as if they are images, and slow ones at that.
image-orientation To rotate an image.	No	No	No	No	No	No	No	Yes

object-fit	No	Yes	No	No	Yes	No	No	No	No	No
Opera Mini on BlackBerry doesn’t support `cover`. Those on iOS, Android, and Symbian do.
object-position	No	No	No	Yes	No	No	No	No	No
Same syntax as background-position.

Main gradient test

This is the main gradient test. If a browser fails it, it gets a No and I don’t investigate it any further.

This is an example of a cross-browser linear gradient.

background: -webkit-linear-gradient(0deg,red 10%,yellow 30%,green 60%); background: linear-gradient(90deg,red 10%,yellow 30%,green 60%);

This is an example of a cross-browser radial gradient.

background: -webkit-radial-gradient(60% bottom,circle closest-corner,red 10%,yellow 30%,green 60%); background: radial-gradient(circle closest-corner at 60% bottom,red 10%,yellow 30%,green 60%);

Wolfgang AT-AS45FW note: Wolfgang is a Dutch importer and re-brander of phones. In this particular case they seem to have bought Chinese (? probably) phones, re-branded them, then re-sold them to the Whoop company, which re-branded them and sold them to the Hema chain of supermarkets, which sells them to consumers as the Whoop Echo. Supply chain management FTW!
