How to Make a Square in CSS?

Designing a website can sometimes feel like piecing together a puzzle. One of the essential pieces you might need is a square or rectangle.

This guide will dive deep into how you can create squares and rectangles using CSS, embellish them with colors, and understand some advanced CSS properties like “object-fit” and “polygon”.

How to Draw a Box in HTML

HTML, the foundational language for web pages, doesn’t have a direct tag for boxes. Instead, we use the <div> tag, which stands for “division.” It’s a container element that can hold other elements inside. By default, a <div> takes up the full width of its parent container but has no height unless content is inside or a specific height is set.

<div></div>

How to Create a Rectangle in CSS

With the <div> in place, styling it with CSS will shape it into a rectangle or square. The following code will create a rectangle:

div {
    width: 300px; 
    height: 150px; 
    border: 1px solid black;
}

If you’re aiming for a square, simply give it equal width and height.

div {
    width: 200px;
    height: 200px;
    border: 1px solid black;
}

How Do You Make a Color Square in CSS?

Adding color to your square is straightforward. Use the background-color property:

div {
    width: 200px;
    height: 200px;
    background-color: blue;
}

What is object-fit in CSS?

The object-fit property in CSS determines how content (like an image or video) should fit inside its container. It’s especially useful when you’re trying to fit an image inside a square or rectangle without distorting its proportions. The common values include:

• fill: Stretches the object to fit the container.
• contain: Scales the object to maintain its aspect ratio while fitting within the container.
• cover: Scales the object to cover the container, potentially cropping the content.

For instance, if you have an image inside your square:

<div>
    <img src="path_to_image.jpg" alt="Description">
</div>

You can style it as:

div img {
    width: 100%;
    height: 100%;
    object-fit: cover;
}

How to use polygon in CSS?

The clip-path property in CSS allows you to clip an element into various shapes, including polygons. The polygon function defines the shape using a series of points.

For instance, to create a triangle:

div {
    clip-path: polygon(50% 0%, 0% 100%, 100% 100%);
}

This technique, combined with advanced designs, plays a crucial role in creating CSS Holy Grail Layouts.
