person: CSS grid is a big topic, so I just want to show you one of my favourite grid features: areas!

let’s say you want to build a layout

grid-template-areas lets you define your layout in an almost visual way

grid-template-areas:
"header header" 
"sidebar content"

I think of it like this:
Illustration of a two rectangles side-by-side, both labelled “header”. Underneath them are two rectangles, side by side, labelled “sidebar” and “content”

write your HTML

<div class="grid">
   <div class="top"></div> 
   <div class="side"></div> 
   <div class="main"></div> 
</div>

2. define the areas

.grid {
   display: grid;
   grid-template-columns: 200px 800px;
   grid-template-areas:"header header" 
   "sidebar content";
}

3. set grid-area

.top {grid-area: header} 
.side {grid-area: sidebar} 
.main {grid-area: content}

result:
Illustration of a long rectangle, labelled “.top”. Underneath it are two rectangles, side by side, labelled “.side” and “.main”
