Can anyone tell me what's wrong with this code!

here’s my code-
div {
display: inline-block;
margin-left: 5px;
height:100 px;
width:100 px;
border:2px solid black;

100 and px is one argument, so there can’t be any spaces in it.

What is the error message you receive?

tysm…,i removed the space between 100 and px and it worked!! :smile:
