I am creating new extension now my css is conlfiction with some of websites
i have follwing css
ul.myextentiontagit input[type="text"] {
width:100px;
}
and website have like
input[type="text"] {
height:1200px;
line-height: 120px;
}
now my exeantion is also picking website css.
What is the best way to write css for that.
Edit: i already added pre-class name myextention in all css.still it is conflicting. even after clearing cache and everyhting

To avoid conflicts you can use Namespaces.That will avoid many conflicts.Hope that helps.

This common when you are putting your HTML and CSS code inside the other webpages.
To differentiate between your and other website CSS, you need to use specific CSS selectors for elements styling.
Some like following you have to use -
<!-- Website CSS-->
--- whatever here it is ---
<!-- your CSS --->
.my-container .my-button{
}
<!-- your HTML-->
<div class="my-container">
<div class="my-button"> My Button </div>
</div>
Now, whatever CSS other website has it will not conflict with yours , beacuase you have given specific selector for styling

Can i apply an external css file only to a div and its children?

I don't think it is possible, but I will ask anyway:
Can I apply an external css file (Bootstrap for instance) to a div and its children without affecting the rest of the page.
For example, I need to migrate a footer written with Bootstrap over to an existing page. That page does not use bootstrap. If I link Bootstraps css at the top of the page, the css is applied to the whole page which ruins existing css. How can I just apply the bootstrap styles to the footer section without having to rewrite most of the page's css?
Any suggestions?
I ended up using LESS to compile a new css of bootstrap with a prefix of .bootstrap as seen below. It works, but i wonder if there is a more traditional way of handling this problem.
file: bootstrap-only.less
.bootstrap {
#import 'bootstrap.css'
}
file: bootstrap-only.css
.bootstrap .container {
width: 100%;
}
file: page.html
<style>
.container { width: 20px; }
</style>
<link rel="stylesheet" type="text/css" href="bootstrap-only.css">
<div class="not-bootstrap">
<div class="container">I am 20px</div>
</div>
<div class="bootstrap">
<div class="container">I am 100%</div>
</div>
You can try usig scooped css.Please do refer the following sample code.
<div>
<style scoped>
#import "filename.css";
</style>
//your div with its children will come here
</div>
Your inline styles should not be affected by adding Bootstrap as inline styles take precedence over styles from external resources. The only elements that should be affected are the ones in the page that share class names with bootstrap classes.
You can try referencing the Bootstrap css before your own css and your stylesheet will take precedence over the Bootstrap css. Unfortunately this may add styles additional styles to some of your classes which that you didn't explicitly reference in your stylesheet and may still change the look of your page.
For those classes that exist in both bootstrap and your stylesheet it's probably best to just change the names of those classes in your stylesheet and page. A quick way to do this is to use "replace" search for the class name and replace it with the new class name most IDEs have a way to "replace all" so it's often just a bit of typing and a few clicks to change a bunch of styles.
You can try using the Angular 2+, where you can simply create an component and us it anywhere irrespective of the page css. Basically it will create a shadow DOM and will not be accessible outside that component.

Override Wordpress CSS

I have wordpress site with some layout.
I need to change some css there, but got troubles overriding it.
Via webbrowser my CSS looks like:
It is places (genetated?) somewhere in theme.
Every time I refresh page I got different 'class-xyz' (on the screen it is: class-GkgfbCohxE) name in #inbound-list
I have added to custom CSS below (changed color):
But this is not loaded.
All structure of this CSS:
Do you know how to enable ovverriding this element?
It depends on the theme and plugin you use.
For my experience, this dynamic inline CSS may come from the page builder you use. If it comes from page builder, please check your page builder and adjust the style.
If you want to overwrite the css, you could simply put !important after the color attributes.
To override this css you need to use any parent id like below or you can apply some id to your body tag and write ur css with its reference
see my ex below
#parent #one li{
color: blue;
}
#one.asd li{
color: red;
}
<div id="parent">
<ul id="one" class="asd">
<li>aaa</li>
<li>bb</li>
<li>adfdf</li>
</ul>
</div>
If it's a your theme styles, you can create a child-theme, then overwrite the styles. You can also use the same selector in the child-theme css, WordPress knows that it has to take the ones from the child-theme.

Restricting a css to an element and its descendants at runtime

Today I am facing a problem of restricting the scope of css. The
<div class="parent">
<div id="childWithNoCss">
<p>No css</p>
</div>
<div id="childWithCss">
<p>Apply css</p>
</div>
</div>
My css is:
div{
color:red}
p{color:blue}
I need to apply the css specific to the id childWithCss.
The css is fixed (I cannot change it) just need to limit its scope only to a specific element.
I cannot use scope attribute since it is incompatible in some browsers.
Is there any other solution?
Regards
Are you trying to find a workaround for this?
<style scoped>
p {
//some style
}
<style>
If so, there are some jQuery plugins that do the same thing and work for IE, at least for IE 9 and above. Here's one example:
jQuery scoped CSS plugin
If that's not what you're trying to do, can you not just add some nested css? Does this help at all with what you are trying to do?
Load an external CSS for a specific DIV
You can reset the CSS of an element with the css code: all:initial.
You could use some javascript to do this at runtime for the elements you want to reset. I see you tagged your question with angularJS, so jquery should be available.
jquery solution to reset all css for the p in the divs WITHOUT #childWithCss within .parent:
$('.parent div:not(#childWithCss) p').css('all','initial')
http://jsfiddle.net/2yXsL/3/
You should be able to do it with a bit of jquery
if ($('.parent').has('#childWithCss')) {
$('#childWithCss').find('p').css('color', 'red')
}
Reset the color of everything except #childWithCSS to the default text color with a bit of jQuery.
$("p:not(#childWithCSS p)").css("color", "initial");

External CSS file not working alongside bootstrap

I am trying to add custom styling to my web app. Here is the link to my code:
https://github.com/SammyAbukmeil/rps-challenge
In layout.erb I have the following:
<head>
...
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">
<link rel="stylesheet" type="text/css" href="css/custom.css">
...
</head>
Which should be loading my custom.css file.
In views/index.erb I have an ID of test:
<img class="img-responsive center-block" style="margin-top: 40px" id="test"src="http://i.imgur.com/hSuFTzO.png">
and in css/custom.css I am calling that ID:
#test {
margin-top: 50px;
}
But for some reason it doesn't apply my custom styling, although bootstrap (which is being linked in layout.erb and is adding styling to the .erb files throughout the project) is working.
I've tried looking through similar questions on stack overflow without success, also tried google for how to add custom styling to a bootstrap project - everything I'm doing seems to be correct.
Any advice is greatly appreciated. Thanks!
EDIT: So i checked the console and found this:
...
Status Code: 404 Not Found
Request URL: http://localhost:4567/css/custom.css
...
So I guess I'm not linking it right.
Bootstrap selectors are very specific, for example body > div > img.img-responsive. You need to be more specific in order to override the selector. You can test this by using temporally the !important declaration:
#test {
margin-top: 50px !important;
}
If it overrides, you have a working setup that just needs more specific selectors. After that you should remove the !important declaration and add details to the selector:
body > div > img#test {
margin-top: 50px !important;
}
In Sinatra any static files (such as CSS files) should be in the folder pointed to by the public_folder setting. Usually this is named public. In your server.rb you set it to be public but relative to the projects root.
You need to create a public folder at the top level of your project (next to app, view etc.), move your css directory to it and then change the setting in server.rb so that :public_folder points to it, similar to what you have done with the :views setting:
set :public_folder, proc { File.join(root, "..", "public") }
First You need to understand the hierarchy of CSS
You Can use Firebug (Firefox) to identify that your styling is apply or not also what class is overrating your custom css.
Note: Also avoid adding ID for CSS Styling
You need to override the bootstrap selector.
It is not good practice to use this in your finished website, however you can use !important to over ride other style rules.
Example of Use
.element-class{
width:50%;
}
.element-class{
width:100% !important;
}
The element would have the width of 100% here.

Div with external stylesheet?

I have been given an external stylesheet (.css file) that may not altered in any way whatsoever. However I need to apply this stylesheet to a single div and therefore the contents of the div in my already existing webpage. I am currently reading the contents of the stylesheet as text into a blank style tag (using .innerHTML) within the div I need to affect but this still affects the entire web page rather than just the single div. Could someone please help with this?
The IFRAME solution works like this:
In your main HTML file, you'll have your DIV:
<div id="myspecialdiv">
<iframe width="100%" height="100%" frameborder="0" src="divcontent.html"></iframe>
</div>
Style that as you need it. The divcontent.html file should be a complete HTML file, including the content of the DIV tag, and a LINK using your external stylesheet:
<html>
<head>
<link rel="stylesheet" href="path/to/external/stylesheet.css" />
</head>
<body>
<!-- The contents of your DIV -->
</body>
</html>
If you can work with HTML5, you could try using scoped styles. You could include the CSS inside the div, having it affect only its parent:
<div>
<style scoped>
// Styles here
</style>
</div>
This will helps you a lot:

Applies only style to a certain delimited escope. Good luck!
IMHO better than the iframe solution..
related: Limit scope of external css to only a specific element?
If you have access to server-side scripting (eg: PHP), you could create a script that loads the external stylesheet, and appends a class name in front of every entry. Then apply this class to your DIV tag. So, if the CSS includes:
p { font-size: 12px; }
You'd modify that to:
.mydiv p { font-size: 12px; }
And format your DIV as
<div class="mydiv">...</div>
You would then load the script as a stylesheet, rather than the external stylesheet directly.
<link rel="stylesheet" href="path/to/internal/script.php" />
I suggest you can leave the external style sheet as it is and create an internal style sheet with the classes that you want from the external stylesheet to affect your single div and just rename it and apply those renamed classes to the div. The renaming is because the attributes of those classes may affect elements already existing on the page from external stylesheets.
<style>
.xxx {...} /* The renamed class from this internal css that should apply to your div */
</style>
Hope this helps.
I assume that the style specifications inside the external file are not contained in classes or IDs, but are they blanket adjustments to tags like <p> (and thus it cannot be included in your page headers). Include your div in a <style scoped> tag and import the .css file there. See: http://css-tricks.com/saving-the-day-with-scoped-css/
You could assign a CSS prefix to target the section of your document you want to style.
scoped is a good idea, but has browser compatible issue.
I solve this problem by adding pre-class before all selector in css file:
