Conditional Statements in HTML

Conditional statements in HTML allow you to execute different code based on specific conditions. These statements are commonly used in conjunction with JavaScript to create dynamic and interactive web pages.

The If Statement

The if statement is one of the most fundamental conditional statements in programming. It allows you to execute a block of code if a specified condition is true. For example:

      
        <script>
          var x = 10;
          if (x > 5) {
            document.write('x is greater than 5');
          }
        </script>
      
    

The Else Statement

The else statement can be used in conjunction with an if statement to specify a block of code to execute if the condition is false. For example:

      
        <script>
          var x = 3;
          if (x > 5) {
            document.write('x is greater than 5');
          } else {
            document.write('x is less than or equal to 5');
          }
        </script>
      
    

The Else If Statement

The else if statement allows you to chain multiple conditions together. If the initial if statement is false, the else if statement is evaluated. For example:

      
        <script>
          var x = 3;
          if (x > 5) {
            document.write('x is greater than 5');
          } else if (x === 5) {
            document.write('x is equal to 5');
          } else {
            document.write('x is less than 5');
          }
        </script>
      
    

Conditional statements are a powerful feature of HTML and JavaScript, allowing you to create dynamic and interactive web pages. By using these statements, you can control the flow of your code and provide a more personalized experience for your users.
