Bootstrap

Customisable

A great aspect of Bootstrap is that you can customise it's features as its open source software. Bootstrap allows the developer to factor in their needs and tailor their development project accordingly.

Responsiveness

Future Compatibility

Bootstrap comes equipped with many elements that are being considered the future of design itself. For instance both HTML5 and CSS3 are always evolving. Since the framework takes into account the future of design and development, it has the potential to becoming very vital for web developers in the years to come.

Consistency

One of the main reasons this toolset was developed was because Twitter was seeing big inconsistencies between developers working on their projects. This caused some issues both on the development front and the end-user front. Since it works with a central set of development code, Bootstrap’s results are uniform across platforms. You’ll see the same result on Internet Explorer, Chrome and Firefox.

Bundled Javascript plugins

The components such as drop down menu are made interactive with the numerous JavaScript plugins bundled in the bootstrap package. If you project requires sliders, tabs, accordions, then you no longer have to try and test numerous different plugins across the web. Adding these functionalities is just a matter of adding few lines of code and you are all set. With the customization option you can also choose only certain plugins to keep the file size to a minimum.
