Responsive Rounded Buttons

- Coding CSS

Last week I wanted to create three rounded buttons for a client's site.

I didn't keep it in the design but here is some code and explaination of how this is done for responsive cases.

First of all our button needs to have a wrapper with a width. For our example we are going to use a list.

li {
  width: 15%;
  display: inline-block;
}

Now, each button needs to have 100% width and magic trick number 1: we give a zero height and a padding-bottom: 100% to resize the height fluidly. And overflow: hidden to hide the remaining color of the link.

.button {
  width: 100%;
  height: 0;
  padding-bottom: 100%;
  border-radius: 50%;
  overflow: hidden;
}

For the next part, our link needs to have padding-top: 50%; & padding-bottom: 50%; to be in the "middle" of the link and a margin-top half the size of the line-height to create an "absolute middle". It's the same logic with absolute centering things.

.button__link {
    border: 1px solid red;
    display: block;
    width: 100%;
    padding-top: 50%;
    padding-bottom: 50%;
    text-align: center;
    color: #fff;
    text-decoration: none;
    line-height: 2em;
    font-size: 2em;
    margin-top: -1em;
    background: #E9C46A;
  }

Here is a demo of what we created and the sass code for it.

li {
  width: 15%;
  display: inline-block;
}

.button {
  width: 100%;
  height: 0;
  padding-bottom: 100%;
  border-radius: 50%;
  overflow: hidden;

  &__link {
    border: 1px solid red;
    display: block;
    width: 100%;
    padding-top: 50%;
    padding-bottom: 50%;
    text-align: center;
    color: #fff;
    text-decoration: none;
    line-height: 2em;
    font-size: 2em;
    margin-top: -1em;
    background: #E9C46A;
  }
}

That's all you need to know to work with rounded buttons. Below there is a new "section" you can check out about status when I write each post.

Maybe it works for you too :).
