CSS3 - transition-property, implied values; mobile

transition-property, implied values; mobile

Back to the index.

Transitions only work on CSS declarations that have a numerical value; such as left: 20px to left: 200px. However, there are a few cases where a CSS declaration may have an implied value. This page discusses and tests them.

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

Compatibility

Click or touch the test elements. If they change styles immediately, transitions are not supported on the indicated CSS declaration. Instead, they should change slowly.

Then click or touch the test element again. It should transition back in most circumstances.

background-color Test	Yes	Yes	Yes	Yes	Yes	-	Yes	-	Yes	Yes
All browsers interpet `background-color: transparent` as `opacity: 0`. Thus the color value itself doesn’t do a transition: it goes from undefined to red in one step. The opacity, however, transitions from 0 to 1.
border Test	Yes	Yes	Yes	Yes	Yes	-	Almost	Yes	-	Yes	Yes
When doing the test you’ll see that all browsers handle the first one, from none to a border, correctly, but don’t do the second one, from border to none, at all. What’s going on here is that the first transition sets the `border-style` from `none` to `solid`. This is not a transition: the new style is applied directly. However, the `border-color` transitions from the text color to red and `border-width` from 0 to 5. When going the other way, the `border-style` is immediately set to `none`, which hides the border and thus makes the color and width transition invisibile. Thus, although the test may seem to have weird effects, the browsers actually do the right thing. Opera Classic switches the border-color to transparent straight away, but then transitions the border-width.
left Test Should not work	Yes	Yes	Yes	No	Yes	Yes	-	No	Yes	-	No	No
The default `left` value is not `0` but `auto`, which is not a numerical value and thus untransitionable.
letter-spacing Test	Yes	Yes	Yes	Yes	Yes	-	Yes	-	Yes	No
The default `letter-spacing` is `normal`, which should compute to `0`, which is transitionable. Therefore Firefox appears to be in the wrong here.
outline Test	Yes	Yes	Yes	Yes	Yes	-	Yes	-	No	Incomplete
`outline` should work the same as `border`; see above. Firefox doesn’t transition `outline-width` from its implied 0 value to 5; it just transitions the color.
text-indent Test Test Test Test Test Test Test Test	Yes	Yes	Yes	Yes	Yes	-	Yes	-	No	Yes
`text-indent` always has a numeric value (default is 0), so IE’s refusal to transition is a bug.

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!
