class vs id css code example

Example 1: difference between id and class in css

/* The difference between an ID and a class is that an ID 
is only used to identify one single element in our HTML. 
IDs are only used when one element on the page should have a 
particular style applied to it. However,
a class can be used to identify more than one HTML element. */

Example 2: css class

.myclass {
  border:1px solid black;
  background-color: #d2d2d2;
  height:20px;
  width:60px;
}
/*If you give this class to a div in html, it will get the styles you gave
to that class. You can add multiple classes to a div, and multiple divs
can get that class. */
/* I hope I helped! */
