you have to follow only four steps:-

step 1: pen and paper📝

exactly! this easy is your first step is only to take pen and paper 🙂

step 2:Ready🚩

now it's the time to show your drawing skills! just kidding 😉... you have to draw only 4 lines two vertically and two horizontally. just same to same as it is shown below

yes this simple coordinate system you have to draw on your paper

step 3:- Action🎬

it's time to take action with your pen on paper, Now draw your favourite shape, letter any shape you want. I draw a V shape below... obviously, it's my favourite letter for sure 😁 . draw your shape inside the coordinate system

now point a dot in each joint in your shape, there are 6 joints

write it like this (1,2,3,4,5,6), for V coordinate points will be:-

(0 0,15% 0%,100% 75%,85% 0%,100% 0%,50% 100%)

you have to start with a point and draw another point to make a line

step 4:- Code👩🏻‍💻

hehe, I wish I write drama as a heading in step 4 😂... so now it's time to code, there is a CSS property clip-path

The clip-path CSS property creates a clipping region that sets what part of an element should be shown. Parts that are inside the region are shown, while those outside are hidden.

here we want to create a shape so we use the polygon() in clip-path

polygon() -Defines a polygon using an SVG filling rule and a set of vertices.

-webkit-clip-path: polygon(0 0,15% 0%,100% 75%,85% 0%,100% 0%,50% 100%);
  clip-path: polygon(0 0,15% 0%,50% 75%,85% 0%,100% 0%,50% 100%);

for more, you can refer to the MDN official documentation 😎
