Whitespace
Whitespace is used in different ways someways are required and others aren’t.
Required syntax for certain uses (such as separating CSS values)
padding:10px 5px;Without the space between the pixel values here there would be an error and the styles wouldn’t get applied. This could cause a headache trying to find where the issue is.
Not required but encouraged syntax is for readability
body{background:lightblue;font-size:12px;} h1{padding:10px 5px;}while this will work it is definitely harder to read
