Bootstrap Sass Installation and Customization. Bootstrap is a popular, open source framework. Complete with pre-built components it allows web designers of all skill levels to quickly build a site. The only drawback I can find to Bootstrap is that it is built on Less. Less is a CSS preprocessor, and although I could learn Less, I prefer Sass. Normally the fact that it is based on Less would exclude me as a user of Bootstrap, as I do no write plain CSS anymore. Fortunately Bootstrap now comes with a official Sass port of the framework, bootstrap-sass. If you are not familiar with Bootstrap implementing the Sass version can be a little tricky. Installation There are multiple ways to obtain and install bootstrap-sass Download You can download bootstrap-sass from the Bootstrap download page. Compass If you are using Compass then you’ll have Ruby installed. Gem install bootstrap-sass If you have an existing Compass project and want to add bootstrap-sass, run this command: compass install bootstrap -r bootstrap-sass Bower Configuration Setup Bower.
Bootstrap 3 Less Workflow Tutorial. IMPORTANT NOTE: Read the NEW Bootstrap 4 “How to use SCSS Mixins” post here. Bootstrap 3 is still new, and you may not be totally familiar with how it uses Less, and how you can use it too. This is a tutorial on a Less workflow that can get you up and running and using Less right away. It can be confusing to set up a workflow your first time, but once you do it, you’ll never want to go back. And the best part is that you can use the workflow with or without Bootstrap 3. But for this post, I am going to talk about how you can use the power of Less with Bootstrap and make your life a whole lot easier. Nowhere in this post will you see “less is more.” (Read the Part 1 about a Bootstrap Grid Introduction here Bootstrap 3 Grid Introduction Tutorial and The Subtle Magic Behind Why the Bootstrap 3 Grid Works.)

Using Bootstrap 4 Flexbox. The CSS3 Flexible Box, or Flexbox, is a new layout mode to improve arrangement of items on a page that can also manage directions and order within a container to accommodate different screen sizes and different display devices. It works like a box model which modifies the width or the height of its child items filling up the space available without the use of floats. A lot of designers and developers use a Flexbox layout to easily position elements on different screen sizes by just using a small bit of code. This saves a lot of time in the development process. Fortunately, Bootstrap 4 added Flexbox support. Enabling Flexbox via _variables.scss Using the core Sass files inside the Bootstrap 4 package, navigate to the $enable-flex variable in the _variables.scss file.
Let’s try that now. By default, you will have the output like the image below. When we activate Flexbox it will automatically convert each of the columns into flex items matching the heights of columns. See image below. Bootstrap 4: Media Queries using Sass.

Bootstrap 4 Breakpoints Bootstrap 4 has moved entirely from pixel based units to relative em/rem based units with the base font-size of 16 pixels.
Understanding the grid breakpoints within Bootstrap 4 is quite important before we move on to our Sass files. Notice how BS4 does not have a lowest value, which means xs is now the default style – and you would use sm, md, lg and xl breakpoints as overrides.
