Dividing the screen in four blocks - html

Question

My goal is to break my screen in four different blocks that are not the same size, just like in the picture (block one and two should be the same size). I tried using bootstrap which kinda works but it makes it scrollable and I want to avoid that. Is there a way to make it not scrollable and have each block in a fixed size? Any tips would be appreciated. I'm using bootstrap and angularjs.
This is what I have so far, but I want to make full screen.

You should check out CSS "Grid's". Basically, you can declare a grid inside your css and use the grid-template-columns property to display your blocks in various arrangements. Here is a good resource that shows you how to create a custom layout.
The grid property also allows you to declare a height and width which will fix your scrolling problem.
Check this out and start experamenting.
CSS
.grid {
display: grid;
width: 100%;
height: 250px;
grid-template-areas: "head head"
"nav main"
"nav foot";
grid-template-rows: 50px 1fr 30px;
grid-template-columns: 150px 1fr;
}
.grid > header {
grid-area: head;
background: #eee;
}
.grid > navLeft {
grid-area: nav;
background-color: #a072;
}
.grid > main {
grid-area: main;
background-color: #8510ff;
}
.grid > footer {
grid-area: foot;
background-color: #8cffa0;
}
HTML
<header> Hello</header>
<navLeft> Hello</navLeft>
<main> Hello</main>
<p> Hello</p>
<p> Hello</p>
</div> ```
