I'm integrating my Modal from Bootstrap with another site that doesn't use it. I see that bootstrap lets you separate the Javascript for each component. But what about the CSS? If I link to bootstrap.css the whole site will change. I just want enough CSS for the Modal to work. (I tried going thru the CSS file and just guessing what I needed, but it didn't work).

To trigger the modal window, you need to use a button or a link. Then include the two data-* attributes: data-toggle="modal" opens the modal window. data-target="#myModal" points to the id of the modal.
Modal Image A modal is a dialog box/popup window that is displayed on top of the current page. This example use most of the code from the previous example, Modal Boxes, only in this example, we use images.
You can implement it by using any other library for example Bulma , by using another framework that uses jquery, for example jqueryui, by using any other javascript library that could implement a modal, or by implementing it using javascript, or even with only css and html.
Bootstrap 4.3 added new built-in scroll feature to modals. This makes only the modal-body content scroll if the size of the content would otherwise make the page scroll. To use it, just add the class modal-dialog-scrollable to the same div that has the modal-dialog class.
Go to the Bootstrap customize section and select just the modal option in the components section. Download the file, open the bootstrap.css file and copy the entire contents into your own CSS file.
If you try to work out which specific parts you need you'll likely miss something important, and besides, the modal css on its own is not too big.
Update: The link is now here. I found it still added a lot of normalization to the start of the css, but could safely delete it (from html to img, keeping the css from .img-responsive onwards).

Update as of Bootstrap v3.2.5
Thanks to @Gruber for confirmation as of v3.2.5.
The link is still here, to customize the setup as mentioned by @Fisu.
You need to select 4 options though, not just modal as stated. Start by clicking Toggle All to turn everything off, then select these 4 options;
Buttons under Common CSS Close icon under Components Component animations (for JS) under JavaScript components Modals under JavaScript components This should bring all of the CSS over that you'll need. Next is the jQuery plugins section, again start by selecting Toggle All to turn everything off and then just select two plugins:
Modals under Linked to components Transitions under Magic (required for any kind of animations)That's all you'll need, js (bootstrap.min.js) and css (only bootstrap.css which you'll need to modify a bit, explained below). Go to the bottom of that page and select compile and download to grab your package.
One final thing to note. As @Rrrrrrrrrk mentioned, "I found it still added a lot of normalization to the start of the css, but could safely delete it (from html to img, keeping the css from .img-responsive onwards)." This is still valid. I also added the following css to force a few styles into the Modals:
.modal { font-family:Arial,Helvetica,sans-serif!important} .modal p {font-family:"Helvetica Neue",Helvetica,Arial,sans-serif !important; color:#000 !important; font-size:14px;} This just ensures fonts are similar to the original modal styling and don't take on your pages styles (could probably be tweaked a bit more). One final item to note, you could minify the css at this point by running it through http://cssminifier.com/. Saves a few KB.
Implementing the Modal:
I might as well just finish this off. I'm using a cookie plugin because I want to give my users an option to hide the message for 14 days, which is set in the code. Here are the code blocks you'll need:
This should go in the <head> of you document, probably after any of your css, so even just before the ending </head> tag will work.
<!-- CSS NEEDED FOR THE IMPORTANT MESSAGE MODAL POPUP --> <!-- Latest compiled and minified CSS --> <link rel="stylesheet" href="modalsonly/css/bootstrap-3.2.0.min.css"> <!-- END CSS NEEDED FOR THE IMPORTANT MESSAGE MODAL POPUP --> This should go within your <body>. This will create the modal and the css you've included will hide it.
<!-- HTML NEEDED FOR THE IMPORTANT MESSAGE MODAL POPUP --> <div class="modal fade " id="important-msg" tabindex="-1" role="dialog" aria-labelledby="important-msg-label" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button> <h4 class="modal-title" id="important-msg-label">Message Title!</h4> </div> <div class="modal-body"> <p>Message text</p> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> <button type="button" class="btn btn-primary" id="dont-show-again">Don't Show Again</button> </div> </div> </div> </div> <!-- END HTML NEEDED FOR THE IMPORTANT MESSAGE MODAL POPUP --> This code should go just before the ending </body> tag. It loads jQuery, bootstrap, and the cookie plugin I need.
<!-- PLUGINS NEEDED FOR THE IMPORTANT MESSAGE MODAL POPUP --> <!-- Latest jQuery (1.11.1) --> <script src="modalsonly/js/jquery-1.11.1.min.js"></script> <!-- Latest compiled and minified JavaScript --> <script src="modalsonly/js/bootstrap-3.2.0.min.js"></script> <!-- jQuery Cookie --> <script src="modalsonly/js/jquery.cookie-1.4.1.min.js"></script> <!-- END PLUGINS NEEDED FOR THE IMPORTANT MESSAGE MODAL POPUP --> Finally, you'll want to add this script after the plugins above. This is a bit customized to my situation, I'm only launching the modal if there is no cookie set, and if the modal launches created a function to click Don't Show Again which creates the cookie to disable the launch of the modal.
<script> //Start the DOM ready $( document ).ready(function() { //CODE NEEDED FOR THE IMPORTANT MESSAGE MODAL POPUP //Check to see if the cookie exists for the Don't show again option if (!$.cookie('focusmsg')) { //Launch the modal when you first visit the site $('#important-msg').modal('show'); } //Don't show again mouse click $("#dont-show-again").click( function() { //Create a cookie that lasts 14 days $.cookie('focusmsg', '1', { expires: 14 }); $('#important-msg').modal('hide'); }); //end the click function for don't show again //END CODE NEEDED FOR THE IMPORTANT MESSAGE MODAL POPUP }); //End the DOM ready </script> Hope this helps! Good luck.
