1️⃣ What is a Website Layout?

A website layout is the structural framework of a webpage that decides:

Where content appears

📌 Layout = Structure, not colors or fonts.

Header → Logo, title
Navigation → Menu
Main Content → Page data
Sidebar → Extra info
Footer → Copyright, links

CSS

.header, .nav, .footer {
padding: 20px;
background: #ddd;
text-align: center;
}

.main {
display: flex;
}

.content {
flex: 3;
padding: 20px;
background: #f5f5f5;
}

.container {
display: grid;
grid-template-areas:
"header header"
"nav nav"
"content sidebar"
"footer footer";
grid-template-columns: 3fr 1fr;
}

.header { grid-area: header; }
.nav { grid-area: nav; }
.content { grid-area: content; }
.sidebar { grid-area: sidebar; }
.footer { grid-area: footer; }

.container {

display: grid;

grid-template-areas:

"header header"

"nav nav"

"content sidebar"

"footer footer";

grid-template-columns: 3fr 1fr;

}

.header { grid-area: header; }
