I am trying to change the bootstrap tab style. Therefore, my custom style should be similar to these image styles.

I tried it like this, but it does not work. The main thing is not skew the bottom of each tab.
.content .nav-tabs {
background: #dd5b5b;
padding: 15px 0 0 0;
}
.content .nav-tabs > li > a {
padding: 5px 40px;
background: #eaedf2;
border: 1px solid #a48686;
border-bottom: none;
border-top-right-radius: 2em;
border-top-left-radius: 1.5em;
}
Js bin with code still
Can someone help me get the result as shown above using pure css?
Thank.
