[Answer]-Switched to django now tab label width is stretching to tab content width… Hard to explain

I think you miss li closing tag in the html

 <ul class="tabs">
            <li>
                <input type="radio" checked name="tabs" id="tab1">
                <labels for="tab1">Resource Browser</labels>
                <div id="tab-content1" class="tab-content animated fadeIn">
             </li>

I had an extra closing </div> tag near the closing tags of the first tab element. Special shout out to palafox_e! Thanks homey.
