Few days ago I needed to create style sheets with many rounded boxes,
|
||
where different corners had to be rounded differently (think about
|
||
Bootstrap’s [button
|
||
groups](http://getbootstrap.com/components/#btn-groups)).
|
||
|
||
CSS has this nifty shorthand to specify border width in one line, like
|
||
with `border-width: 1px 2px 3px 4px`, but it lacks the same for
|
||
`border-radius`. So I decided to create something similar using [Sass
|
||
mixins](http://sass-lang.com/guide#topic-6) with dynamic
|
||
parameters. Another nice feature you get using the `border-width`
|
||
shorthand is that you can specify less than four parameters, and the
|
||
values will be applied on different sides of your box, so in the end
|
||
all side will have the whole `border-width` set.
|
||
|
||
I wanted to achieve the same for my `border-radius` mixin, although I
|
||
could not start specifically with the `top` side. I decided to go with
|
||
the top right corner for the first parameter, while trying to keep a
|
||
sane repeating pattern. Here is the result:
