* create responsive containers provide more flexibility and allow the user to determine when containers switch from fluid to fixed width. * fix the base container code this commit fixes the non-media portion of the generated CSS. I learned about the `@extends` directive and was able to put it to good use. I create a new temporary map that contains all the main `$container-max-widths` and join it to our 2 special cases of 'xs' and 'fluid'. Then we loop through that and, with the appropriate infixes, extend our placeholder * formatting for style forgot to run my tests before the last push, i think these are better. * finish incomplete comment * fix the responsive containers using the `@extend` directive I was able to clean up this code * fix responsive containers in the navbar mostly we just look through all of our breakpoints so we can include all of the responsive container classes in the tweaks we have to do for the navbar (redeclaring flex properties, don't double up on padding, etc) * Simplify container extends * Simplify navbar containers * Rearrange, add comments, ensure everything is nested in $enable-grid-classes * Reduce new CSS by using attribute selector We avoid using `@extend` whenever possible, and this is more readable * Update _grid.scss * Update _navbar.scss * Add docs for responsive containers, redesign the container layout page * Add to the Grid example

<h1>Bootstrap grid examples</h1>

|
<p class="lead">Basic grid layouts to get you familiar with building within the Bootstrap grid system.</p>
|
|
<p>In these examples the <code>.themed-grid-col</code> class is added to the columns to add some theming. This is not a class that is available in Bootstrap by default.</p>

<h2 class="mt-4">Five grid tiers</h2>
|
|
<p>There are five tiers to the Bootstrap grid system, one for each range of devices we support. Each tier starts at a minimum viewport size and automatically applies to the larger devices unless overridden.</p>

<p>At mobile device sizes, tablets and down, these columns and their nested columns will stack.</p>

<p>The Bootstrap v4 grid system has five tiers of classes: xs (extra small, this class infix is not used), sm (small), md (medium), lg (large), and xl (extra large). You can use nearly any combination of these classes to create more dynamic and flexible layouts.</p>
|
|
<p>Each tier of classes scales up, meaning if you plan on setting the same widths for md, lg and xl, you only need to specify md.</p>
