Series 31H Lug resilient seated butterfly valves are drilled and tapped to meet ASME Class 125/150 and PN16 flanges. Series 31H Valves will not be automated.
We use the class nav-pills instead of nav-tabs which automatically creates a background color for the tab
We applied clearfix to the tab-content to rid of the gap between the tab and the content
We use css to change the background color of the content to be equal to the tab
