Tab header make transparent border for overlapping border

I have a border around my .tab-content and the same border around active .tabs. I've tried adding a transparent border on the bottom to no avail.

my-setup

Is there a way to, where two borders overlap, have one override the other? Or is there a better way to accomplish this?

Here's a jsfiddle to show my basic set up.

.tab-content {
    height:200px;
    width:400px;
    background-color: #aaa;
    border:1px solid #000;
}

.tabs-container {
    height:auto;
    width:400px;
    background-color:#aaabbb;

}

.tabs {
    width:360px;
    margin-left:20px;
}

.tab {
    display:inline-block;
    padding:5px 20px;
}

.tab.active {
    border-left:1px solid #000;
    border-right:1px solid #000;
    border-top:1px solid #000;
    border-bottom:transparent;
    background-color: #aaa;
}
<div class="tabs-container">
    <div class="tabs">
        <div class="tab active">This Tab</div>
        <div class="tab">That Tab</div>
    </div>
</div>

<div class="tab-content">
</div>

You can use a pseudo element to create the bottom border, make it the same color as the background, and position it to cover the dark line.

.tab.active:after {
    content: '';
    border-bottom: 10px solid #aaa;
    position: absolute;
    bottom: -1px;
    left: 0;
    width: 100%;
}


.tab-content {
    height:200px;
    width:400px;
    background-color: #aaa;
    border:1px solid #000;
}

.tabs-container {
    height:auto;
    width:400px;
    background-color:#aaabbb;

}

.tabs {
    width:360px;
    margin-left:20px;
}

.tab {
    display:inline-block;
    padding:5px 20px;
}

.tab.active {
    border-left:1px solid #000;
    border-right:1px solid #000;
    border-top:1px solid #000;
    background-color: #aaa;
    position: relative;
}
.tab.active:after {
    content: '';
    border-bottom:10px solid #aaa;
    position: absolute;
    bottom: -1px;
    left: 0;
    width: 100%;
}
<div class="tabs-container">
    <div class="tabs">
        <div class="tab active">This Tab</div>
        <div class="tab">That Tab</div>
    </div>
</div>

<div class="tab-content">
</div>

Or just move the whole navbar 1px down.

.tab.active {
    border-left:1px solid #000;
    border-right:1px solid #000;
    border-top:1px solid #000;
    background-color: #aaa;
    position: relative;
    bottom: -1px;
}


.tab-content {
    height:200px;
    width:400px;
    background-color: #aaa;
    border:1px solid #000;
}

.tabs-container {
    height:auto;
    width:400px;
    background-color:#aaabbb;

}

.tabs {
    width:360px;
    margin-left:20px;
}

.tab {
    display:inline-block;
    padding:5px 20px;
}

.tab.active {
    border-left:1px solid #000;
    border-right:1px solid #000;
    border-top:1px solid #000;
    background-color: #aaa;
    position: relative;
    bottom: -1px;
}
/* .tab.active:after {
    content: '';
    border-bottom:10px solid #aaa;
    position: absolute;
    bottom: -1px;
    left: 0;
    width: 100%;
} */
<div class="tabs-container">
    <div class="tabs">
        <div class="tab active">This Tab</div>
        <div class="tab">That Tab</div>
    </div>
</div>

<div class="tab-content">
</div>
