step 2: tHE row
- .row class
- syntax: <div class="row"></div>
- rows contain columns & columns contain content; only columns can be immediate children of rows
- rows extend the full width of the container
Step 3: THE column/s
stuff to know about the .col class
- you can define different numbers of columns for different sizes (that adjust according to screensize breakpoints): e.g., <div class="col-sm-10 col-md-6">
- columns go inside rows
- content goes inside columns
- columns have default padding
- rows' negative margins offset padding on the first and last columns (far left and far right)
