I know I can just have a custom stylesheet that overrides the bootstrap component I wish to customize (for example the jumbotron), but is the right way to go about this "problem"? I don't think this can be done with a bootstrap theme, although I haven't read a whole lot on this subject.
You can use your browsers DevTools to inspect an element that you want to change, and in the Rules/Styles section you can see which CSS elements is it using and then you can create your own css file and paste the CSS there and change it so it overrides bootstraps element. Here is how to get the devtools from Chrome https://developer.chrome.com/devtools#dom-and-styles and from Firefox https://developer.mozilla.org/en-US/docs/Tools/Page_Inspector/How_to/Open_the_Inspector. Don't forget to import your CSS customised script under bootstraps so it overrides the CSS that you wish to change.
Use twitter-bootstrap customize on their website to customize it and download the customized files. Or just create a custom CSS file and edit classes like .jumbotron and other stuff
There are a few ways to modify the default bootstrap css and no one way is inherently more or less "right" than any other. It all depends on the coding style of you and/or your team. Here is a list of a few ways that I came up with off the top of my head:
Modify the css file you downloaded from Bootstrap
(My Choice) Override Bootstrap styles with your own CSS. Just be sure to follow the rules of CSS Specificity (External < Internal < Inline) and if you have trouble getting a certain rule to apply try reading this answer or force it with !important
NOTE: This is likely NOT a comprehensive list, just a starting point.

I think the title is a bit vague but my vocabulary is limited in english. I'll try to explain what I want to do.
I have two CSS files from products I have no control ( are not mine ). Lets say AdminLTE bootstrap and a JQuery plugin.
The problem is the Box class is in both styles.
and messing my flight indicators from the JQuery plugin. I know I have to choose the order of CSS style files or add important to one of them but I'm afraid of start to mess with my bootstrap interface.
Is there any other way to solve this?

you don't, you could simply write a selector with higher specificity which would override the jQuery plugin styles, like body div.instrument .box
I have changed my css sheet for my entire site and it works great. The change has to do with the background color of rows in tables. Although it does what I want, there is one view that I would like to be exempt from this alteration. Is there a way to exclude this view from the change or create a new css sheet for this specific view?
Well, I would come up with a CSS styling strategy. The goal should be to minimize CSS and overrides. Also, having an extra CSS file for just one page will cause an extra HTTP round trip to get the resource. My recommendation is to stick extra CSS classes on this view. Then, override precisely the styles that you need in your global CSS styles.
I figured out the solution which ended up being much easier than I expected. Since I am very new to using CSS and HTML I was unaware of the style tag. However, that is what I was looking for. For anybody looking at this in the future, just use:
<style>
(CSS that you would like to override)
</style>
I have some h1, h2, h3 and a lot of bootstrap snippets that I want to apply only to a specific part of my site, I added a unique class, say .unique but it would take hours to prefix over 1000 of CSS lines
I use sublime text
Thanks in advance
You could use a CSS-preprocessor like LESS or SASS (there are more). Both can do what you want, by just doing this:
.unique {
// Old CSS goes here
}
The have many other advantages over normal CSS.
common I would like to give you some ideas, cause i think your question has something to do with control css overriding.
the Jost's LESS or SASS solution is very good actually to prefix cause can use nested css features, but it requires a compile process, their eventually compiled files are still css. cause the .less or .sass files can not be recognized for html to render styling.
Another thinking To avoid css conflicts and wrong overriding,
Instead of including global styling, see if you can embed them in part of the specific section/page where they can get higher priorities than the rest global styles.
even the same css, generally, !important > inline css > internal css > external css
or javascript can trigger css override after previous css finished rendering on the page.
Instead of using css priorities or script running priorities to override styles, making two external mobile.css, destop.css for example, then using javascript to reload page to include different stylesheet when device width are detected to have been changed in browser resizing behavior.(This is one pop way used in responsive view)
using IDE to locate css patterns and replace them with your prefix if it's simple to match all the patterns.
I was looking for a (simple) WYSIWYG Editor jQuery Plugin that's compatible with Bootstrap 3. I've seen a lot WYSIWYG Editors jQuery Plugin that were compatible with the previous Bootstrap, but my website uses Bootstrap 3, so each time I implemented such a jQuery Plugin, my Bootstrap 3 would ruin the buttons and mess the whole editor up.
So now I'm asking whether there is an option to enable the Bootstrap 2 stylesheet only for one div and its contents.
I assume a iframe could work, but then, I need the WYSIWYG Editor's contents (which are in the iframe then), along with text inputs on the 'non-iframe'.
One way you might be able to solve this would scope your css for that div. This is what I have implemented with a content management system that I have created.
Let say for example you give the WYSIWYG Div an ID of HTMLEditable.
you could target that div with your css and all the css within that div.
#HTMLEditable .WYSIWYG{
....css goes here
}
#HTMLEditable p{
....css goes here
}
The above css will only apply to that div.
Then its just a case of finding the correct css that you need in that div.
Note you may need to override/reset the css for that div to stop your bootstrap3 applying to it.
Here is an example of a reset css. (You will need to scope this as well to make sure you don't reset all your css).
EDIT: use LESS
To make this easier you can use LESS which is what bootstrap uses.
#HTMLEditable {
//import the modal css
#import "bootstrap.css";
}
you will need to make a file 'HTMLEditable.less'. Then Add the code to similar to the above.
The less will them compile the above into css and will scope everything in the css to #HTMLEditable
Check out the LESS site and look ate the nesting. This is what you are after. This site will also show you how to compile it.
You need to put the class or id of this div before all css rules. You can do it like this if you need a css file and not less.
#HTMLEditable{
paste in all of your css
}
than copy all of this paste it here: http://less2css.org/ in the less area and it will generate the right css for you.
I'd like to import an external CSS (eg. Bootstrap) into my site-- the problem is I'd like to apply the Bootstrap styles only to a specific region of the page. When I include Bootstrap, it applies its styles to the entire page, restyling all tables, divs, etc.
Is it possible to only apply Bootstrap to a region (say a parent div or something?)
Thanks
The only way to do this is to have a separate iframe for the content you want to style with Bootstrap (unless you want to edit the Bootstrap CSS, and add your outer div's selector to the beginning of EVERY rule).
HTML5 introduced the new scoped attribute, which is made specifically for your use case, but has not yet been implemented by any one of the major browsers.
If you are using jQuery (which you probably are, since all of Bootstrap's Javascript functionality is dependent upon jQuery), you might wanna try Simon Madine's jQuery Scoped CSS plugin.
Import Bootstrap before your own styles. That way your own styles will overwrite the changes made by Bootstrap where applicable.
I've only tried this locally and not given it any thorough testing but it seems to work fine. I created a div around the content and assigned it an id. Then prefixed all of the bootstrap selectors with the id I assigned the surrounding div. The prefixing was done with a couple of search and replace operations. Perhaps it can be done easier with less
Forgot to mention that the body selector of the bootstrap.css has to be replaced with the id and not prefixed like the other selectors.
