The <button> tag is used to create clickable buttons on the web page. The difference between these elements and buttons created with the <input> tag is that you can place the content (images or text) inside the <button>.
Use the <input> element to define a button within HTML form, as browsers display the content of the <button> tag differently.
The <button> tag comes in pairs, the content is written between the opening (<button>) and the closing (</button>) tags.
<html> <head> <title>Title of the document</title> </head> <body> <h1>Here will be our button</h1> <button type="button">Click</button> </body> </html>
Using CSS styles
You can apply CSS styles to the <button> tag to change the appearance of the button, its size, color, text font, and so on.
<html> <head> <title>Title of the document</title> </head> <body> Ordinary button <button type="button">Add to the recycle bin</button> <hr /> Button with red text <button type="button" style="color: red;"><b>HTML Book </b></button> <hr /> Button with increased font size <button type="button" style="font: bold 14px Arial;">Download the book </button><br /> </body> </html>
The <button> tag doesn’t have required attributes; however, we recommend always use the type=”button” attribute, if the tag used as an ordinary button.
