## Modals
|
||
Modals are popups for providing important information before continuing further.
|
||
|
||
To create such dialogs/pop-ups on the top of current page Bootstrap provides Modal plugin.
|
||
|
||
#### Code Example (Bootstrap v4.1) :
|
||
|
||
```html
|
||
<!DOCTYPE html>
|
||
<html>
|
||
<head>
|
||
<meta charset="utf-8">
|
||
<meta name="viewport" content="width=device-width">
|
||
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
