/*
In grid-template-areas You can’t create a non-rectangular area, 
so the property can’t be used to create an ‘L’ or ‘T’ shaped area
*/


/*
The media query order is important:

That's by design of CSS — Cascading Style Sheet.

It means that, if you apply two rules that collide to the same elements, 
it will choose the last one that was declared, unless the first one has the !important marker or is more specific
