Last Updated : 30 Jul, 2019

Styles in HTML are basically rules that describe how a document will be presented in a browser. Style information can be either attached as a separate document or embedded in the HTML document.

There are 3 ways of implementing style in HTML :

Inline Style : In this method, the style attribute is used inside the HTML start tag.
Embedded Style : In this method, the style element is used inside the <head> element of the document.
External Style Sheet : In this method the <link> element is used to point to an external CSS file.

Inline Style : In Inline styling, the CSS rules are directly written inside the starting tag using the style attribute. The style attribute includes a series of CSS property and value pairs. Each ‘ property : value ‘ pair is separated by a semicolon ( ; ).

Example:

<!DOCTYPE html>
<html>
<head>
    
</head>
<body>
  
    <h1 style="color:Blue;font-size:25px;">
        Example of Inline Style
    </h1>
  
    <p style="color:red;">First paragraph</p>
  
    <p style="color:green;font-size:40px;">
        Second paragraph
    </p>
  
    <hr style="border-color:orange;">
  
</body>
  
</html>

Output :

Embedded Style : Embedded or internal style sheets only affect the document they are embedded in. Embedded style sheets are defined in the <head> section of an HTML document using the <style> tag.

Example:

<!DOCTYPE html>
<html lang="en">
  
<head>
    <style type="text/css">
        body {
            background-color: powderblue;
        }
          
        h1 {
            color: black;
            font-family: arial;
        }
          
        p {
            color: yellow;
            font-family: verdana;
        }
    </style>
</head>
  
<body>
    <h1>Example of Embedded Style</h1>
    <p>First paragraph.</p>
</body>
  
</html>

Output :

External Style Sheet: External Style Sheets method can be useful when the CSS has to be applied to various web pages. An external style sheet holds all the style rules in a separate document that you can link from an HTML file on your site.
There are two ways of attaching external style sheets –

Linking External Style Sheets
Importing External Style Sheets

Linking External Style Sheets :
In this method, an external style sheet is linked to an HTML document using the <link> tag.

Example:

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" type="text/css" 
            href="/html/css/externalstyle.css">
</head>
<body>
    <h3>Example of Linking External Style Sheet</h3>
    <p>First paragraph.</p>
</body>
</html>

Output :

Importing External Style Sheets :
External style sheets can be loaded into an HTML document using “@import”. The “@import” statement instructs the browser to load the CSS file. Other CSS rules can also be included using the <style> element.

Example:

<!DOCTYPE html>
<html>
<head>
<style type = "text/css"> 
    @import url("/html/css/importstyle.css");
p{color:powderblue; font - size : 30px;}
</style>
</head>
<body>
    <h3>Example of external style sheet using import</h3>
    <p>First paragraph</p>
</body>
</html>

Output :
