[Grid Layout] Describe a grid layout using named grid lines

We can use named grid lines to describe our grid layout. Let’s see how to apply this to our grid-template-columns and grid-template-rows, and how to refer to these from our grid items.

Syntax like:

            grid-template-columns:
            [left-sidebar-start] 1fr
            [main-content-start] 2fr
            [right-sidebar-start] 1fr;

We can name those whatever we want to.

You can also give multi names for one line:

            grid-template-columns:
            [left-sidebar-start] 1fr
            [left-sidebar-end main-content-start] 2fr
            [main-content-end right-sidebar-start] 1fr
            [right-sidebar-end];

And we also named the last columns name as 'right-sidebar-end'.

Later we can contorl the position like this:

            grid-template-rows:
                [body-start] 6fr
                [body-end footer-start] 2fr
                [footer-end];

The same for the rows:

            grid-template-rows:
                [body-start] 6fr
                [body-end footer-start] 2fr
                [footer-end];

So for four column lines: 

 --> left-sidebar-start

 --> left-sidebar-end, main-content-start

 --> main-content-end, right-sidebar-start

 --> right-sidebar-end

For three row lines:

 --> body-start

 --> body-end, footer-start

 --> footer-end
