A question about <div>


#1


I have no idea why 'learn-more' have three

s?
the fist one was set its class. i got it.
the second one maybe used to set the container ( I guess )
But what the third
mean?
Thx!

#2

i think it becomes this in the end:

<div class="learn-more">
  <div class="container">
    <div class="row">
      <div class="col-md-4">

this will be explained later, if you can't wait you can read about it on the bootstrap-grid options


#3

i got it
thank you for answering !
