Cara menggunakan template bootstrap github

Before getting started with Bootstrap’s modal component, be sure to read the following as our menu options have recently changed.

  • Modals are built with HTML, CSS, and JavaScript. They’re positioned over everything else in the document and remove scroll from the so that modal content scrolls instead.
  • Clicking on the modal “backdrop” will automatically close the modal.
  • Bootstrap only supports one modal window at a time. Nested modals aren’t supported as we believe them to be poor user experiences.
  • Modals use
    
    
      Launch demo modal
    
    
    
    
    Modal title

    3, which can sometimes be a bit particular about its rendering. Whenever possible, place your modal HTML in a top-level position to avoid potential interference from other elements. You’ll likely run into issues when nesting a
    
    
      Launch demo modal
    
    
    
    
    Modal title

    4 within another fixed element.
  • Once again, due to
    
    
      Launch demo modal
    
    
    
    
    Modal title

    3, there are some caveats with using modals on mobile devices. for details.
  • Due to how HTML5 defines its semantics, has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript:

var myModal = document.getElementById('myModal')
var myInput = document.getElementById('myInput')

myModal.addEventListener('shown.bs.modal', function () {
  myInput.focus()
})

Keep reading for demos and usage guidelines.

Examples

Below is a static modal example (meaning its

Live demo

Toggle a working modal demo by clicking the button below. It will slide down and fade in from the top of the page.

Woohoo, you're reading this text in a modal!



  Launch demo modal



Modal title

Static backdrop

When backdrop is set to static, the modal will not close when clicking outside it. Click the button below to try it.

I will not close if you click outside me. Don't even try to press escape key.

Modal title

When modals become too long for the user’s viewport or device, they scroll independent of the page itself. Try the demo below to see what we mean.

This is some placeholder content to show the scrolling behavior for modals. Instead of repeating the text the modal, we use an inline style set a minimum height, thereby extending the length of the overall modal and demonstrating the overflow scrolling. When content becomes longer than the height of the viewport, scrolling will move the modal as needed.

You can also create a scrollable modal that allows scroll the modal body by adding



  Launch static backdrop modal



Modal title

0 to


  Launch static backdrop modal



Modal title

1.

This is some placeholder content to show the scrolling behavior for modals. We use repeated line breaks to demonstrate how content can exceed minimum inner height, thereby showing inner scrolling. When content becomes longer than the prefedined max-height of modal, content will be cropped and scrollable within the modal.

This content should appear at the bottom after you scroll.



Vertically centered

Add

Modal title

2 to

Modal title

1 to vertically center the modal.

This is a vertically centered modal.

This is some placeholder content to show a vertically centered modal. We've added some extra copy here to show how vertically centering the modal works when combined with scrollable modals. We also use some repeated line breaks to quickly extend the height of the content, thereby triggering the scrolling. When content becomes longer than the prefedined max-height of modal, content will be cropped and scrollable within the modal.

Just like that.

Tooltips and popovers can be placed within modals as needed. When modals are closed, any tooltips and popovers within are also automatically dismissed.

Using the grid

Utilize the Bootstrap grid system within a modal by nesting

Varying modal content

Have a bunch of buttons that all trigger the same modal with slightly different contents? Use

Toggle between modals

Toggle between multiple modals with some clever placement of the
