Dear readers, today we continue our Bootstrap 3 lessons, and in the new lesson we will prepare a new page layout that will suit different purposes. The huge advantage of using CSS frameworks is that the developer does not need to think about different issues of the layout, most of which were solved by creators of frameworks. For instance: cross-browser compatibility, support for different screen resolutions (responsiveness) and so on. The developer only needs to indicates what to display and when to display (depending on conditions), the rest the framework does itself. This approach can greatly accelerate the layout of the site. Another advantage of Bootstrap is its popularity. This means that another developer will be easier maintain your code.
