how to make a css file seperate to the html file code example
Example 1: start a css file
*{
margin: 0;
padding: 0;
color: unset;
box-sizing: border-box;
text-decoration: none;
outline: none;
overflow-x: hidden;
}
Example 2: css without separate file
just add any style inside the first <p> or other element tag using style=" ;"
<p style="font-size: xx-large;">test</p>
