Example 3: bootstrap grid

<!----------------------- BOOTSTRAP GRID SYSTEM ------------------------>

This code will create 4 boxes placed side by side, which will be 
dynamically positioned, according to the size of the screen. We define 
the following behavior: 


<!-- Desktop Display: we have 4 columns per row (each occupies 3 units out of 12)  -->

class = "col-lg-3"   <!-- display large with 12/3 = 4 columns -->


<!-- Tablet Display: we have 3 columns per row (each occupies 4 units out of 12)  -->

class = "col-md-4"   <!-- display medium with 12/4 = 3 columns -->


<!-- Mobile Display: we have 2 columns per row (each occupies the 6 units of 12)  -->

class = "col-sm-6"  <!-- display small with 12/6 = 2 columns -->


<!-- CODE -->

  <div class="row">
    <div class="col-lg-3 col-md-4 col-sm-6" style="background-color:red; border:1px solid black;">
      One of four columns
    </div>
    <div class="col-lg-3 col-md-4 col-sm-6" style="background-color:yellow; border:1px solid black;">
      One of four columns

Use this class to style all textual form controls such as user input, titles, etc.
<form>
 <div class=”form-group”>
 <label for=”exampleFormControlInput1”>Email address</label>
 <input type=”email” class=”form-control” id=”exampleFormControlInput1”

.form-control-file
Add this class whenever you need to provide the user with an option to upload a file to the form.
<input type=”file” class=”form-control-file” id=”exampleFormControlFile1”>
.form-control-lg and .form-control-sm.
Create a visual hierarchy within your form by adding .form-control-lg to make bigger input areas and .form-control-sm to
make smaller ones.
<input class=”form-control form-control-lg” type=”text” placeholder=”.form-controllg”>
<input class=”form-control form-control-sm” type=”text” placeholder=”.form-controlsm”>
