How to divide a webpage in three vertical parts?

Question

I wanted to divide a landing page into three vertical parts. But I am failing to do so.

Here is my code:

const left = document.querySelector(".left");
const middle = document.querySelector(".middle");
const right = document.querySelector(".right");
const container = document.querySelector(".container");

left.addEventListener("mouseenter", () => {
  container.classList.add("hover-left");
});

left.addEventListener("mouseleave", () => {
  container.classList.remove("hover-left");
});

middle.addEventListener("mouseenter", () => {
  container.classList.add("hover-middle");
});

middle.addEventListener("mouseleave", () => {
  container.classList.remove("hover-middle");
});

right.addEventListener("mouseenter", () => {
  container.classList.add("hover-right");
});

right.addEventListener("mouseleave", () => {
  container.classList.remove("hover-right");
});

:root {
  --container-bg-color: #333;
  --left-bg-color: rgba(223, 39, 39, 0.7);

</body>

I am getting an output like this: output of the current code

I wanted to insert .middle into the center part of the page? Where am I making a mistake? Transitions are also overlapping onto each other.

you could try adding in your css:

..essentialy moving the middle container 33.3% to the left (where the first container ends)

.split.middle {
 left: 33.3%
}

although the best way would be to use display:flex https://css-tricks.com/snippets/css/a-guide-to-flexbox/

I just got it but the problem is in transition. When I hover over it div elements are overlapping onto each other. – Ashish Dhase Jan 04 '18 at 12:01

Did some changes in your CSS code. You have to set the position of the middle section on hover like below

.split.middle {
  left: 33.333%;
}

.hover-left .middle {
  left: 70%;
}

.hover-middle .middle {
  left: 15%;
}

.hover-right .middle {
  left: 13%;
}

const left = document.querySelector(".left");
const middle = document.querySelector(".middle");
const right = document.querySelector(".right");
const container = document.querySelector(".container");

left.addEventListener("mouseenter", () => {
  container.classList.add("hover-left");
});

left.addEventListener("mouseleave", () => {
  container.classList.remove("hover-left");
});

middle.addEventListener("mouseenter", () => {
  container.classList.add("hover-middle");
});

middle.addEventListener("mouseleave", () => {
  container.classList.remove("hover-middle");
});

right.addEventListener("mouseenter", () => {
  container.classList.add("hover-right");
});

right.addEventListener("mouseleave", () => {
  container.classList.remove("hover-right");
});

:root {

You can do this entirely in CSS with Flexbox. Make the container <div> a flex container:

.container {
  display: flex;
}

And the split <div>s flex items:

.split {
  flex: 15 1 0;
}

15 (flex-grow): each flex item will take 15 "shares" of extra horizontal space
1 (flex-shrink): flex items will shrink evenly, each giving up 1 "share" of horizontal space
0 (flex-basis): base width of each flex item is 0 instead of being based on its content

And for the widening effect, make the hovered <div> greedy:

.split:hover {
  flex-grow: 70;
}

You can avoid the extra ::before pseudo-elements with gradient backgrounds:

.split.middle {
  background:
    linear-gradient(var(--middle-bg-color), var(--middle-bg-color)),
    url('https://image.ibb.co/m56Czw/designer.jpg') center center no-repeat;
  background-size: cover;
}

This creates a background image with a gradient that fades from one semitransparent color to the same semitransparent color, and puts it on top of your JPEG background image.

Remove all the positioning code on the <div>s, and you're set.

:root {
  --container-bg-color: #333;
  --left-bg-color: rgba(223, 39, 39, 0.7);
  --left-button-hover-color: rgba(161, 11, 11, 0.3);
  --middle-bg-color: rgba(39, 217, 223, 0.7);
  --middle-button-hover-color: rgba(14, 32, 196, 0.151);
  --right-bg-color: rgba(43, 43, 43, 0.8);
  --right-button-hover-color: rgba(92, 92, 92, 0.3);
