OpenCart header consists of several classes. These classes hold different sections of the header. It has div1 to div10 class. Each class controls different parts of the site. div1 class has the logo of the site. div3 maintains the top-right navigation. Menus are positioned with the div4 class. div5 has the search bar and div6 holds the language bar, while div7 controls the language and currency units. We will see how we can customize each class to make our header better.
