HTML-Button-Tag

HTML Button Tag allows creating an active button control on a web page using the HTML document. This element is declared within the body tag. Why do we need a button element? Normally, when a user accesses a web page, the most common thing he does is clicking somewhere on a website, leading to the next URL Page. To do so, the Button element cannot do it alone; it is created by a form action where the web forms have a default submit button click.

Buttons were created using element; they function like element with additional possibilities like adding content and images between the button tag. The content text appears between the opening and closing tags on a button. You can perform actions on the button using JavaScript or include it in a form. CSS probably handles the application of special styles to the button, but different browsers introduce their unique styles.

Syntax:

Like other HTML tags, even button tags have both opening and closing tags, and the button type is defined using attributes.

<button>
// some stuff like content / image
</button>

Attributes of HTML Button Tag

No Special attributes have been used as they don’t have any required attributes; instead, they are used as an ordinary button with the type=” attribute. “Even this element is styled using CSS, with the properties to alter the changes in the button tag. Those properties are CSS font family, Font-weight, Text-decoration, and font-Style. Coloring properties like Background-color and layout properties like text-overflow and text-indent.
