How to Create Alert Button in HTML?

Last Updated : 03 Jun, 2024

To create alert buttons in HTML, define buttons with different classes for various alert types Success, Info, Warning, Danger, and Default, and style them with background colors, border colors, and hover effects for visual feedback. Utilize CSS transitions to add smooth animations when the buttons are hovered over.

Approach

Start by creating a new HTML file that sets up a webpage with a centered heading and five alert buttons, styled with CSS for different alert types: Success, Info, Warning, Danger, and Default.
The <style> section defines general button styles (.button) such as padding, text alignment, font size, transitions, cursor, and border-radius.
Each button type (.success_btn, .info_btn, .warning_btn, .danger_btn, .default_btn) has specific background and border colors, matching their alert purpose.
Hover effects are applied to each button type, changing the background color and slightly moving the button upwards for a visual effect.
The div container uses a flexbox to center its content both horizontally and vertically, ensuring the buttons are well-positioned in the viewport.

Example: The example below shows How to Create an Alert Button in HTML.
