What grid should I use for Web design?

Hierarchical grids are most commonly found in web design. The purpose of these grids is to arrange elements in order of importance. They can be a little more flexible but they still use columns, rows, and modules to help with organization.

What is the difference between a multicolumn grid and a modular grid?

While a multicolumn grid splits a page vertically into a number of columns, a modular grid subdivides a page both vertically and horizontally into modules. The columns and rows and the alleys between them create a matrix of cells, or modules.

Should I use grid for responsive design?

Using a grid-view is very helpful when designing web pages. It makes it easier to place elements on the page. A responsive grid-view often has 12 columns, and has a total width of 100%, and will shrink and expand as you resize the browser window.
