It is an easy-to-use free open source framework that is used to create responsive designs that automatically scale to look great on all devices (e.g., phones, tablets and desktops). It supports mobile first methodology and it is compatible with all modern browsers.
Quickly prototype or build an entire app with Sass variables and mixins, responsive grid system, extensive prebuilt components, and powerful plugins built on jQuery.
While easy to implement, you will discover that Bootstrap used a lot of:
Classes (e.g., class = "nav navbar")
Attributes (e.g., data-toggle)
Div tags (e.g., <div> <div>...</div> </div>)
Containers (e.g., fixed and fluid)
Rows / Columns
Objective
In this tutorial, we will create a four column web site that will fill the screen horizontally (in columns) on a large screen but will convert to vertical (or stacked) on smaller screens.
Optional sections and steps can either be skipped altogether or done later.
Real Content
Once you have completed this tutorial, you can go back and replace the text, URLs, buttons, etc. with your own content.
Select the text and replace it with your own real content.
Change the dummy links (#) to real links to pages that you want them to go to.
CAUTION: Do not add a URL to a drop down menu (e.g., Training).
CHECK POINT: Save the file and preview it in a browser. You should see YOUR content displayed.
Scale the page to see how it responds to different sizes.
