The HTML classes mentioned do not appear to be present in the document

section, I've observed a common occurrence in HTML pages where classes are referenced that don't seem to exist within the actual document. I wonder if these classes are being sourced from external locations or if they are simply concealed somewhere deep within the code. Typically, classes would be defined similar to this:
<html>
<style>
.maincontentdiv{some code here}
</style>
</html>

Answer №1

External style sheets are the way to go when it comes to CSS styles. Your provided example demonstrates an internal style.

There are three main types of CSS styles:

1 . Internal style can typically be found within the head tags.

<style type="text/css">
.class 
{ 
width: 100%; 
}
</style>

2 . Inline style is directly added to HTML tags.

 <div style="width: 100%;"></div>

3 . It's generally best practice to use external styles, which can be linked to your webpage.

<link rel="stylesheet" type="text/css" href="Style.css" />
