To create a square, you can use the rect element inside the svg element in HTML.
TL;DR
<!-- Create square in SVG -->
<svg>
<rect x="0" y="0" width="30" height="30" />
</svg>
For example, to make a 30*30 (width and height) square, first we can define the rect element inside the svg element like this,
<!-- Create square in SVG -->
<svg>
<rect />
</svg>
But this alone wouldn't show anything on the screen since it doesn't know how to draw the square on the screen. For that we have to set some attributes on the rect element like:
- the
xattribute, which tells where to start drawing in thex-axis. It is called the x-coordinate. - the
yattribute, which tells where to start drawing in they-axis. It is called the y-coordinate. - the
widthattribute, to define the width for the square in our case it is30px. - the
heightattribute, to define the height for the square in our case it is30px.
So it may look like this,
<!-- Create square in SVG -->
<svg>
<rect x="0" y="0" width="30" height="30" />
</svg>
So in the end, we will have a square drawn to the screen like this,

And we have drawn a square successfully using SVG in HTML. Yay 🎊!

That's all 😃!
