Grid-template-areas (CSS grid system)

Grid-template-areas

grid-template-areas

Defines a grid template by referencing the names of the grid areas which are specified with the grid-area property

  • Repeating the name of a grid area causes the content to span those cells
  • A period signifies an empty cell.
  • Each row in your declaration needs to have the same number of cells.
  • Adjacent periods mean a single dot. As long as the periods do not have spaces between them.
  • The grid-gap property defines the grid’s gutters and is shorthand for grid-column-gap and grid-row-gap.
  • This is the fun part. grid-template-areas defines the areas available in the grid. The name given to grid areas are arbitrary but should be sensible. The grid-template-areas also provides a crude visual representation of the page layout.

    Discoveries/Rules:

    • You cannot seperate a single grid-area with a dot
      grid-template-areas: 
      "side . side " /* This will not work */
      "head head head "
      "realtor realtor realtor";
      
    • You cannot seperate a single grid-area with an area
      grid-template-areas: 
      "side side side "
      "head realtor head  "/* This will not work */
      "head realtor head  ";/* This will not work */
      
    • An area cannot go but horizontal and vertical at a time
      grid-template-areas: 
      "side side side " /* is will not work */
      "side realtor head  "
      "side realtor head  ";
      
    • Ensure the content of a container are all assigned a grid area if the container is been given a grid-teamplate-area

This is cool

<div class="container"> 

    <div class="sidebar">
      sidebar
    </div>

    <header class="header">
      header
    </header>

    <div class="realtors">
      realtors
    </div>
</div>

    <section class="features">
      features 
    </section>

But this will be messy

<div class="container"> 

    <div class="sidebar">
      sidebar
    </div>

    <header class="header">
      header
    </header>

    <div class="realtors">
      realtors
    </div>

    <section class="features">
      features /* Because of this */ 
    </section>
</div>

With the container been a gird system

.sidebar {
  background-color: orange;
   grid-area: side;
}

.header {
  background-color: green;
  grid-area: head;
}

.realtors {
  background-color: blue;
   grid-area: realtor;
}
.features {
  background-color: purple;
   grid-area: fea ;
}

.container {
  display: grid;
  border: 1px solid red;
  grid-template-columns: repeat(3, auto) ;
  grid-template-rows: repeat(3, 50px);

  grid-template-areas: 
    "side .... .... realtor"
    "side head head  realtor"
    "side . . .";
}
