HTML | style attribute - GeeksforGeeks

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>
