You would add an anchor tag like this to your post/page to create the button:
<a href="#" class="button pumpkin">My Button</a>
That will set the button text of “My Button”. The size is set automatically based on the text, or you could use this to set the size:
.button {
height: 25px;
width: 150px;
}
The theme applies the following default css; you could set your own padding/margins:
.button {
padding: 10px 20px;
display: inline-block;
}
Then something like this to color it:
.button.pumpkin,
.button.pumpkin:visited {
background: #D35400;
color:#FFF;
}
.button.pumpkin:hover,
.button.pumpkin:active {
background: #C54E00;
color:#FFF;
}
