adding Masonry style images to section of a website - html

Question

Ive been trying to add a masonry section of images to my website. However it is not aligning correctly. It just stacks the pictures onto of each other. How could I go about creating a masonry section using css/html? Or maybe creating a table that gives the masonry effect?
MY HTML:
<div class="masonry">
<div class="item">IMAGE GOES HERE</div>
<div class="item">SECOND IMAGE </div>
THIRD IMAGE
<div class="item">FOURTH IMAGE</div>
</div>
MY CSS:
.masonry { /* Masonry container */
column-count: 4;
column-gap: 1em;
}
.item { /* Masonry bricks or child elements */
background-color: #eee;
display: inline-block;
margin: 0 0 1em;
width: 100%;
}
The picture below is what I am trying to achieve:

Here you go:
#container {
height: 100%;
width: 100%;
}
#left > img:nth-of-type(1) {
height: 25vh;
width: 35vw;
}
#left > img:nth-of-type(2) {
height: 60vh;
width: 35vw;
}
#left, #right {
display: inline-block;
}
#top-right, #bottom-right {
display: block;
}
#top-right > img:nth-of-type(1) {
width: 25vw;
height: 60vh;
}
#top-right > img:nth-of-type(2) {
width: 35vw;
height: 60vh;
}
#bottom-right > img:nth-of-type(1) {
width: 40vw;
height: 25vh;
}
#bottom-right > img:nth-of-type(2) {
width: 20vw;
height: 25vh;
}
<div id="container">
<div id="left">
<img src="Image 1">
<br>
<img src="Image 2">
</div>
<div id="right">
<div id="top-right">
<img src="Image 3">
<img src="Image 4">
</div>
<div id="bottom-right">
<img src="Image 5">
<img src="Image 6">
</div>
</div>
</div>
