Android浏览器不支持具有百分比值的边界半径

Question

Is there a known issue using % values in border radius on Android browsers?

I notice that when I use:

.element {
  -webkit-border-radius: 10px;
  -moz-border-radius: 10px;
  border-radius: 10px;
}

The border radius seems to work on all mobile browsers, but when I use:

.element {
  -webkit-border-radius: 50%;
  -moz-border-radius: 50%;
  border-radius: 50%;
}

The border radius does not apply on Android browsers.

Answer 1

Yes there is: check here, and click on known issues.

Here's what it says:

1. Android Browser 2.3 does not support % value for border-radius.

2. Border-radius does not work on fieldset elements in IE9.

3. The stock browser on the Samsung Galaxy S4 with Android 4.2 does not support the "border-radius" shorthand property but does support the long-hand properties for each corner like "border-top-left-radius".

What are you using the percentage value for? Please tell us, so we can further help you.

Now, since you are using it to make circles, there's a dirty hack you can use:

#circle {
  border-radius: 9999px; /* makes it a circle */
}

That should work fine.
