I have free account on CodePen. In my code I use Bootstrap but I also override some Bootstrap classes in the CodePen CSS editor. In the head tag of HTML editor, I defined the loading order:
link rel="stylesheet" type="text/css" href="bootstrap.min.css" <br>
link rel="stylesheet" type="text/css" href="custom.css"
I.e. my custom.css I must override the Bootstrap classes. But it does not work in the CodePen editor. I have to use the !important rule to override Bootstrap classes too many.
The main thing is my code works perfectly in Google Chrome and Firefox without using the !important rule when I open custom.html on my local computer.
Why does not it work in the CodePen editor and why does it make such a big difference?
It seems that the order is :
!important
inline style
<style> in the html part
style in the css part
style in css settings.
If you want to avoid adding !important, you should add your link in the settings.
Go to the Settings -> css-> ->Add External Stylesheets/Pens -> add you css link -> save & close.

When I included the Bootstrap style file (bootstrap.min.css), it conflicted with my other styles and menu, which makes the page displays incorrectly. I have found this selector below in the Bootstrap CSS file causes the issue. If I download and store the bootstrap file locally, remove that code block, my page will work correctly. However, I will loss other useful options such as "glyphicon".
*{
-webkit-box-sizing:border-box;
-moz-box-sizing:border-box;
box-sizing:border-box
}
If I include the bootstrap files using CDN like this (which will mess up my page styles because of the above selector *{}), is there a way in my page <style></style> that can remove or disable that block of code above when it loads?
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>
Thanks in advance,
Kind of a newb question. I'm working with Boostrap to create a mobile responsive portfolio. What do you do if you want to make a change to the default Bootstrap classes? Like if I wanted to take the padding off of the class="container"? The links are only connected to the minified version of css and js. So if I make a change to the regular version .css, there's nothing connecting the change. Do I have to change the .min.css version? Should I be able to repeat a class in my own personal css page?(I've tried unsuccessfully) Thanks, any advice would help.
Two methods that I know of:
1) Make edits to the .min.css file, or
2) Add '!Important' to the your personal css, like so:
.testDiv{
font-color: white !Important
}
This will overwrite any classes that have set a font-color for .testDiv
*note: using !important is not a recommended technique, but it gets the job done
You can override the classes in your own CSS file (make sure you import it into your HTML after the original CSS files from bootstrap). Like,
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="path/to/css/bootstrap.min.css">
<!-- Optional theme -->
<link rel="stylesheet" href="path/to/css/bootstrap-theme.min.css">
<!-- Custom Tweaks to theme (Add your changes to this file) -->
<link rel="stylesheet" href="path/to/css/style.css">
<!-- Latest compiled and minified JavaScript -->
<script src="path/to/js/bootstrap.min.js"></script>
However, if you are going to make lots of modifications like that, I suggest you create your own customized version
In my main css file I have this:
background: url(/images/bg_1.jpg) repeat;
And it works fine, I have a background image showing. But when I include the bootstrap.min.css v3.1.1 file in the html (above my css file in the code), the background just goes white.
<link rel="stylesheet" type="text/css" href="/CSS/bootstrap.min.css" />
Any ideas why?
Chances are the bootstrap.min.css contains a css declaration which has a higher specificity
on the element(s) in question. Use firebug or the chrome inspector to look at the styles being applied to this element. You'll be able to see which css declration has a higher specificity and which has therefore overridden your main.css declaration.
I created a stylesheet for jquery mobile using the ThemeRoller tool. It looks really great on the ThemeRoller page. In my mobile app... not so good. I think there must be some conflicts in definitions between my stylesheet and the jquery stylesheets.
Rails layout file:
<%= stylesheet_link_tag "jquery_mob_theme.min", "jquery.mobile-1.1.0.min", "stylin.mobile" %>
For those of you not familiar with rails it is rendered:
<link href="/stylesheets/jquery_mob_theme.min.css?1338304118" media="screen" rel="stylesheet" type="text/css" />
<link href="/stylesheets/jquery.mobile-1.1.0.min.css?1338312435" media="screen" rel="stylesheet" type="text/css" />
<link href="/stylesheets/stylin.mobile.css?1337894014" media="screen" rel="stylesheet" type="text/css" />
Is the only way to deal with this to wade through thousands of lines of css to look for conflicts? Is there a css debugging tool that will detect that in a stylesheet? I could change the jquery file names to scss and then roll them into one stylesheet. I am familiar with Firebug and Web inspector which check styles on one page. That wouldn't help... right?
Thanks.
Unfortunately for you, All of css is based on inheritance so there is no automated way of knowing of a conflict or if an object has just overriden the styling of a parent. I think the best bet is to force rails to show the mobile version of the site on a desktop pc and then you can use the Google chrome inspector. It will show you all styles applied to a specific object. It only shows relevant styles with line numbers in the stylesheet so you aren't stuck wading through css. You can also edit it in chrome to see what your changes will look like before you change your stylesheet.
Firebug (an extension for Firefox) can show all styles applied to any given element, as well as which styles are overridden by other styles. You would have to view your mobile site from a desktop browser, but this can be done in Firefox by changing the useragent to match that of a mobile device (iPod, Android, etc.)
If you plan on using webkit on your site, Firefox is not a great choice as it does not render webkit css styles. An alternative is to use Safari and its development tools (which can be activated in the options menu).
If you need to debug from an actual mobile device, there aren't many options. If you can get Opera mobile onto the device, it comes with a decent debugger called Dragonfly.
The order of your stylin Stylesheets matters for what gets overridden. Make sure your style sheet is before both of the jQuery style sheets.
I'm using twitter bootstrap. My problem is that font-sizes in tables are wrong. For some reason the User Agent stylesheet is overriding the bootstrap table styles.
On the twitter bootstrap page (http://twitter.github.com/bootstrap/base-css.html) everything is of course working correctly.
In my inspector I see the following difference:
My page:
The twitter bootstrap page:
So definitely the problem is that the user agent stylesheet is overriding the bootstrap styles.
I haven't been able to figure out why this is different on my page and the twitter bootstrap page.
Most of the other CSS is working fine.
My css import:
<link href="/media/bootstrap/css/bootstrap.css" rel= "stylesheet">
CSS import on twitter bootstrap page:
<link href="assets/css/bootstrap.css" rel="stylesheet">
I actually figured this out myself. I had the <!DOCTYPE html> tag wrongly written. So if you have this problem make sure the doctype declaration is correct!
Please import the docs.css into your application as well. If I must say so, you must have realized that the Twitter Bootstrap Docs are using bootstrap.css and a custom docs.css. Try doing, which you can download from the github package. Then, try playing around with the table classes in docs. css without messing with the master css. Or try adding DOCTYPE in headers.
<link href="/media/bootstrap/css/docs.css" rel= "stylesheet">
If declaring <!DOCTYPE html> in the very beginning doesn't work, then it's probably not your user-agent style sheet casuing it. It may be Bootstrap's style sheet overriding your styles (I've had this problem). Make sure your style sheet is linked to after Bootstrap's style sheet in your HTML.
<link href="css/bootstrap.min.css" rel="stylesheet">
<link href="css/mystylesheet.css" rel="stylesheet"> <!-- Your custom style sheet goes after Bootstrap's -->
I had the same issue as the OP. I wanted lovely small text and some user stylesheet was overiding it and putting:
font-size: medium;
When I wanted:
font-size:8pt;
I placed the following at the top of my HTML page:
<!DOCTYPE html>
All was good then, a bad habit to get into to not declare doctype at the top. All user stylesheets have now gone.
To discover what is overriding what on your CSS it is always a good idea to inspect element (F12) and you can modify and untick attributes on the fly until you get to right, then update your CSS file with it!
However if you do have a user stylesheet issue, these values will be locked.
Check whether your CSS is called or not in browser dev tools (press F12) under network column.
If it is not called, use your style sheets with1 rel="stylesheet" type="text/css".
It worked for me.
