I am confused about the sequence of CSS styles that applies to HTML. I am creating HTML elements and adding styles from JavaScript. Additionally, I also have a stylesheet that applies to elements.

JavaScript:
element.style.someStyle = ' ';

element.classList.add('style');
CSS:
element { 
    someStyle = ' ' 
}

What will be the precedence order?


Let's say YOUR website is a house;

HTML in your house is going to be all the walls, columns, and more. By themselves they look ugly.

CSS comes in place to put the style on them like painting, designs and more.

YOU first build the house(HTML), then you paint it(CSS). But with time you realize you need to add a new room to you house(HTML), the builder(JS) adds the new room, and put the CSS in place which gets applied to the new elements.

Every time the builder(JS) add a new part to the house(HTML), the designer(CSS) will styled it.

Now in practice:

you should load your CSS at the top (head tag) so all styles are ready once needed. In the others hand the JS, should be loaded at the end before the closing tag of the body.

The location order of precedence is: browser default rules, external style sheet rules, embedded styles, and inline style rules. Specific rules take  Order is not limited to a single stylesheet. The order of the stylesheet in the document matters even more. Check out this document with three distinct style… uh… let’s call them chunks. A chunk being either a <link rel="stylesheet">, a <style> block, or an @import ed stylesheet.


What is the sequence of application?

Following is the order of precedence of how the styles get applied.

  1. Inline - Placed in the HTML element tag itself.
  2. Internal - Placed in the view page inside a <style> tag.
  3. External - Placed in the external style sheet (.css) file.

That is to say - the styles which reside closest to the HTML tag will take the precedence.

To demonstrate this following is a short illustration:

/* external style sheet */
body
{
  background-color: red;
}
<!Document HTML>

  <style type="text/css">
    /* internal style */
    body
    {
      background-color: green;
    }
  </style>

  <!-- inline style -->
  <body style = "background-color: blue">

    <h1>Hey there!</h1>

  </body>

</HTML>
