Example

In the following program, we are using the HTML <button> tag to create a button with the name "click" in HTML.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML Button</title>
</head>
<body>
   <!--create a button-->
   <h1>HTML button</h1>
   <button>click</button>
</body>
</html>

When we run the above code, it will generate an output consisting of the text along with a click button on the webpage.

Example

Following is another example of an HTML <button> tag. Here, we are creating an HTML button named "ClickMe!" Using the <button> tag, and, we are using CSS to style the button we have created.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML Button</title>
   <style>
      button {
         width: 100px;
         height: 30px;
         background-color: green;
         color: white;
         cursor: pointer;
      }
   </style>
</head>
<body>
   <!--create a button-->
   <h1>HTML button</h1>
   <button>ClickMe!</button>
</body>
</html>

On running the above code, the output window will pop up displaying the click button along with a CSS applied to it on the webpage.

Example

In this example, we are creating multiple buttons in HTML using the <button> tag. Then, we are using CSS to give different styles to each created button.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML Button</title>
   <style>
      button:nth-child(2) {
         background-color: aqua;
         width: 100px;
         height: 30px;
         border-radius: 10%;
      }

      button:nth-child(3) {
         background-color: green;
         width: 130px;
         height: 30px;
         color: white;
      }

      button:nth-child(4) {
         background-color: blueviolet;
         width: 90px;
         height: 30px;
         color: white;
         border-radius: 10px;
      }

      button:nth-child(5) {
         background-color: red;
         width: 80px;
         height: 30px;
         cursor: pointer;
         border-radius: 5px;
      }

      button:nth-child(3):hover {
         background-color: transparent;
         color: black;
         cursor: pointer;
      }
   </style>
</head>
<body>
   <!--create a button-->
   <h1>HTML buttons</h1>
   <button>Click</button>
   <button>Hover me!</button>
   <button>Submit</button>
   <button>Danger</button>
   <button>Default</button>
</body>
</html>

When we run the above code, it will generate an output consisting of the buttons applied with different CSS properties applied to it on the webpage.

Example

In this program, we are creating an HTML button using the <button> tag. Then, we are using the "disabled" attribute to disable the created button..

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML Button</title>
</head>
<body>
   <!--create a button-->
   <h1>HTML button</h1>
   <button disabled>Submit</button>
</body>
</html>

On running the above code, the output window will pop up displaying the text along with click button that is disabled on the webpage.
