How do we write CSS like Wordpress with expanding right div? - html

Question

We are writing a custom website, but we want it to look similar to Wordpress, so we have written the code with the 'sticky' left position bar, and the scrolling right one.
But when you bring the page inward, the right columns wraps under the left one. Any ideas why and how to resolve?
Here is the CSS code:
html, body, section, article, aside {
min-height: 100%;
}
.sidemenu
{
position: sticky;
top: 0;
height: 100vh;
background-color: #333333;
color: #ffffff;
width: 160px;
float: left;
}
.menu-link a
{
padding: 8px 2px 2px 8px;
display: block;
color: #ffffff;
text-transform: capitalize;
}
.pagebody
{
float: left;
max-width: 95%;
text-align: left;
padding: 20px;
}
So you have two DIVs, left is 'sidemenu' right is 'pagebody'.
Hope you can help.

Answer 1

To fix the position of the sidebar, you need to used position: fixed;. After that, wrap the sidebar div and body div into one container and set its width to 100% (I also gave the body a margin of 0 at this point to remove gaps).
Give the body div a left-margin equal to the width of the sidebar, then set the width of the body using a calculation (as shown below). I also gave it a really long height to demonstrate scrolling.
You can omit your floats.
Here is the adjusted code:
html,
body,
section,
article,
aside {
min-height: 100%;
margin: 0;
}
.main {
width: 100%;
}
.sidemenu {
position: fixed;
top: 0;
height: 100vh;
background-color: #333333;
color: #ffffff;
width: 160px;
}
.menu-link a {
padding: 8px 2px 2px 8px;
display: block;
color: #ffffff;
text-transform: capitalize;
}
.pagebody {
width: calc(100% - 199.75px);
text-align: left;
padding: 20px;
height: 300vh; /**** used to demonstrate scrolling ****/
margin-left: 160px;
background-color: #BBB;
}
<div class="main">
<div class="sidemenu">
Side Menu
</div>
<div class="pagebody">
body
</div>
</div>
