A grid provides order and structure in a website design. Horizontal and vertical lines intersect to form a grid in which elements of a design are placed and content is neatly aligned. It enables designers and developers to work together for quick prototyping and reorganizing of layouts.
In many website designs, you don’t obviously see the grid as it is invisible, but it was used to give the page its structure. Shown below however are some striking website templates designed using the grid not just as the under griding of the design, but as an essential design element.
