Question

Any tips?

Answer 1

You won't get that rounded edge on the tip of the nipple of the button unless you use an image and the :after pseudo-element but you can come close to it by using css triangles. Here is short demo i made that uses some color trickery to come close to that effect:
CSS
button.btn {
position:relative;
}
button.btn:after {
content: " ";
display: block;
width: 0;
height: 0;
border-top: 14px solid transparent;
border-bottom: 14px solid transparent;
border-right: 14px solid #e2e2e2;
position: absolute;
top: 50%;
margin-top: -14px;
right: 98%;
z-index: 2;
}
button.btn:before {
content: " ";
display: block;
width: 0;
height: 0;
border-top: 14px solid transparent;
border-bottom: 14px solid transparent;
border-right: 14px solid #A0A0A0;
position: absolute;
top: 50%;
margin-top: -14px;
right: 97%;
z-index: 1;
}
.btn-primary {
background: #e2e2e2; /* Old browsers */
background: -moz-linear-gradient(left, #e2e2e2 0%, #d1d1d1 47%, #fefefe 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, right top, color-stop(0%,#e2e2e2), color-stop(47%,#d1d1d1), color-stop(100%,#fefefe)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(left, #e2e2e2 0%,#d1d1d1 47%,#fefefe 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(left, #e2e2e2 0%,#d1d1d1 47%,#fefefe 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(left, #e2e2e2 0%,#d1d1d1 47%,#fefefe 100%); /* IE10+ */
background: linear-gradient(left, #e2e2e2 0%,#d1d1d1 47%,#fefefe 100%); /* W3C */
text-shadow: 0 -1px 0 #fff;
color:#777;
border: 1px solid #A0A0A0;
}
I did not include the :hover and :active state styles so you can play around mixing some colors by using the Colorzilla gradient generator.
Here is a demo of what the button looks like:
