Syntax
Following is the syntax to create a radio button in HTML.
<form> <input type="radio" name="name? " value=" ">Male </form>
Example 1
In the following example, let us learn how to use radio buttons in HTML forms ?
<!DOCTYPE html> <html> <body> <head> <meta charset="UTF-8"> <meta name="description" content="meta tag in the web document"> <meta name="keywords" content="HTML,CSS"> <meta name="author" content="lokesh"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> <p>Branch</p> <form> <input type="radio" name="Branch" value="CSE">CSE <input type="radio" name="Branch" value="IT">IT <input type="radio" name="Branch" value="ECE">ECE <input type="radio" name="Branch" value="EEE">EEE <input type="radio" name="Branch" value="ivil">Civil <input type="radio" name="Branch" value="Mech">Mech </form> </body> </html>
Example 2
You can try to run the following code to learn how to work with radio buttons in HTML ?
<!DOCTYPE html> <html> <body> <head> <title>HTML Radio Button</title> </head> <p>Gender</p> <form> <input type="radio" name="gender" value="male">Male <br> <input type="radio" name="gender" value="female">Female </form> </body> </html>
Example 3
We also use <label> tag along with the input tag. The <label> tag defines a label for several elements in the HTML.
We mainly use label for defining the value for the radio button.
<!DOCTYPE html> <html> <body> <head> <meta charset="UTF-8"> <meta name="description" content="meta tag in the web document"> <meta name="keywords" content="HTML,CSS"> <meta name="author" content="lokesh"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> <p>Branch</p> <form> <input type="radio" id="CSE" name="Branch" value="CSE"> <label for="CSE">CSE</label> <input type="radio" name="Branch" value="IT"> <label for="CSE">IT</label> <input type="radio" name="Branch" value="ECE"> <label for="CSE">ECE</label> <input type="radio" name="Branch" value="EEE">EEE <input type="radio" name="Branch" value="ivil">Civil <input type="radio" name="Branch" value="Mech">Mech </form> </body> </html>
Example 4
Set to checked if you want to select it by default of any of the option. We use checked attribute value to true to select a option by default. Look at the example below ?
<!DOCTYPE html> <html> <body> <head> <meta charset="UTF-8"> <meta name="description" content="meta tag in the web document"> <meta name="keywords" content="HTML,CSS"> <meta name="author" content="lokesh"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> <p>Branch</p> <form> <input type="radio" id="CSE" name="Branch" value="CSE" > <label for="CSE">CSE</label> <input type="radio" name="Branch" value="IT" checked="true"> <label for="CSE">IT</label> <input type="radio" name="Branch" value="ECE"> <label for="CSE">ECE</label> <input type="radio" name="Branch" value="EEE">EEE <input type="radio" name="Branch" value="ivil">Civil <input type="radio" name="Branch" value="Mech">Mech </form> </body> </html>
