The grid system
Like any grid system, the Bootstrap grid is a library of HTML/CSS components that allow you to place a website’s content in desired locations easily. Bootstrap’s grid system needs a container to hold rows and columns. The container provides the proper width for the layout and acts as a wrapper. Bootstrap is built on responsive 12-column grid layout system. It has four different classes depending on the device, and can be combined with one another to create flexible layouts. Offsetting and nesting is also possible in fixed and fluid width layouts.
A website generally includes headings, tables, buttons, labels, etc. Since Bootstrap is an HTML and CSS front-end framework, it makes the styling and design process even simpler. It provides users with basic templates which are easy to use and improve.
Bootstrap is an open source community of Github, with friendly support from the experts across the web and is continually being updated meaning if there is anything wrong, you can easily get the support of experts.
