Css parent selector depending on another class being present - css

my markup is something like this:
<li class="cont">
<a> Click Here</a>
<form> </form>
</li>
I want to change the background colour of the anchor tag if the form is applied a class for ex: ng-dirty. The form gets applied this class by the angularJs framkework, when that happens I would want to highlight the 'a' tag by changing its background colour.
How can I do this using pure Css(or sass)?
Thanks,
Chris.


There no specific CSS selector for this but you can achieve the desire effect with the combination HTML change & box-direction:reverse;. Write like this:
HTML
<div class="cont">
<form class="ng-dirty">
<input type="text" value="Hi"/>
</form>
<a> Click Here</a>
</div>
CSS
.cont{
display:-moz-box;
display:box;
display:-webkit-box;
box-direction: reverse;
-moz-box-direction:reverse;
-webkit-box-direction:reverse;
-moz-box-orient:vertical;
-webkit-box-orient:vertical;
box-orient:vertical;
}
.cont > *{
display:block;
}
.ng-dirty + a{
background:yellow;
}
Check this http://jsfiddle.net/8YnTw/ it's with pure css.


You could do this really simply with angular:
<a ng-class="{'dirty-class': myForm.$dirty}"> Click Here</a>
<form name="myForm">
</form>

Use the next css should work:
.ng-dirty a {
background-color: red;
}

Set background color accordion heading

I want to change the color of an accordion depending on status on the current item in the list.
I want to use something like ng-class="{status: item.status}" (where I have testClass: true)
The problem now is that I can't set the color of the whole accordion heading.
<accordion>
<accordion-group ng-repeat="item in items" class="animate-repeat" is-open="status.open">
<accordion-heading>
<div ng-class="{testClass: true}">
<p>Test</p>
</div>
</accordion-heading>
<div class="row">
<div class="col-sm-12 col-xs-12">
<div class="text-content font-size-14">{{item.text}}</div>
</div>
</div>
</div>
</accordion-group>
</accordion>
CSS
.testClass {
background-color: burlywood;
}
Any idea how to solve this?
I found similar problem here, but the solution didn't work for me
https://github.com/angular-ui/bootstrap/issues/3038
fiddle:
http://jsfiddle.net/f8ce1b0w/2/

Apply the class to the 'accordion-group' and then style with css.
HTML
<accordion-group ng-controller='MyAccordionGroupController' class="test" is-open="isopen">
CSS
.panel {
&.test {
& > .panel-heading {
background-color: red;
}
}
}
http://jsfiddle.net/BramG/f8ce1b0w/8/

You'll want to move the applied class higher in the hierarchy:
http://jsfiddle.net/f8ce1b0w/7/
Then your css will look like :
.panel-warning .panel-heading {
//customize your css here
}
The problem is you are placing the test-item inside an item with padding. Instead, place the test-item-class higher up, and then use css to target the items.
If your states will match to Bootstrap states, then you may want the validation class names from here: https://getbootstrap.com/docs/4.0/migration/#panels
(panel-success, panel-info, panel-warning, panel-danger)
These class names are already in your Bootstrap css.

This is the solution to your problem
.test{
background-color: red;
}
.test-parent.panel-default > .panel-heading {
background-color:red;
}
<accordion-group ng-controller='MyAccordionGroupController' is-open="isopen" class="test-parent">
<accordion-heading>
<div class="test">
I can have markup, too!
</div>
</accordion-heading>
This is just some content to illustrate fancy headings.
</accordion-group>

How to change angularJS's default css styles? Search box etc

Is there a way to change the default styles of AngularJs search box?
<div ng-controller="PersonListCtrl">
<div class="bar">Search:
<input ng-model="query">
</div>
<ul class="" ng-show="query">
<li ng-repeat="person in persons | filter:query">{{person.name}}</li>
</ul>
</div>
</div>
I would like to change the colour and size of the search box and perhaps change the text colour. I've messed around in the CSS but it doesn't seem to be effecting anything.
I've tried
#bar {
background-color: #d7d7d7;
color:#000000;
}
and
.bar{
background-color: #d7d7d7;
color:#000000;
}

AngularJS does not introduces any styles as far as I know. You need to assign the id or the class to the HTML element:
<input ng-model="query" id="bar">
or
<input ng-model="query" class="bar">

You're currently targeting the wrapper of the input, you could just use
.bar input {
instead

How can I style .class-0, .class-1, .class-2 with a common selector?

I want to style the following CSS classes; is there any short styling technique for this?
.test-0 { }
.test-2 { }
.test-3 { }
/* etc. */
I am looking for something like:
.test-%d% { }
I want to dynamically create many test-* classes with different numbers and common styles.
Update
here is my actual situation
<input type="button" value="click" class="button_class" />
<h1 class="ui-widget-header">Question - 1 </h1>
<div class="ui-widget-content">
<div id="form_container-0">
<div class="placeholder">Add your form fields here</div>
<div style="clear: both;"></div>
</div>
</div>
When user click the above button then same structure will clone and append to the end of the form
so the form will be as
<h1 class="ui-widget-header">Question - 1 </h1>
<div class="ui-widget-content">
<div id="form_container-0">
<div class="placeholder">Add your form fields here</div>
</div>
<div id="form_container-1">
<div class="placeholder">Add your form fields here</div>
</div>
</div>
the css class form_container-[%d] will be created dynamically by jquery.
so i want to add style to this class.
also it would be great if you share optimised code for cloning the structure with
different ID.
Please do let me know if you still have doubt.
thanks

You can use an attribute selector.
div[class*='test-'] {...}

I think #Ed W have the right solution BUT I have an extra idea while is not straight forward is shorter than what you have. And will help to make different testing that is waht I think you want... fiddel http://jsfiddle.net/ncubica/2sj9W/
css
.test-1,
.test-2,
.test-3,
.test-4,
.test-5{
color:#F60;
display:block;
}
.test-5{
color:blue
}
html
<span class="test-1">One</span>
<span class="test-2">Two</span>
<span class="test-3">Three</span>
<span class="test-4">Four</span>
<span class="test-5">Five</span>
span five will be in blue color... so you can override the class you want to test and play with it.
Also you can use selectors like
HTML
<div>
<span>I'm pink</span>
<span>I'm pink</span>
<span>I'm pink</span>
<span>I'm pink</span>
<span class="test-1">I'm red</span>
</div>
CSS
div > span{
color:pink;
display:block;
}
div > span.test-1{
color:red;
}
and the last span will be red. I hope this help.
My two cents...

Is it possible to change two styles independently inside the same link tag on a:hover?

I have an anchor link which has an image and two spans of text, a title and a tagline with different colors, and i want them to change differently when hovering the link.
<style>
span.title {color: #666;}
span.tagline {color: #aaa;}
</style>
<a class="button" href="http://www.link.com" target="_blank">
<div style="display:block">
<img src="images/button.png">
<span class="title">TITLE</span><br>
<span class="tagline">tagline</span>
</div>
</a>
I wonder if it's possible to use something like:
<style>
a.button:hover span.title {color: #000;}
a.button:hover span.tagline {color: #2ae;}
</style>

Yes thats possible. Psuedo class :hover doesn't have to be for the last element in the selector.

For future reference its easier/quicker to try this out for yourself in jsFiddle before asking questions.

Use CSS to make a span not clickable

<html>
<head>
</head>
<body>
<div>
<a href="http://www.google.com">
<span>title<br></span>
<span>description<br></span>
<span>some url</span>
</a>
</div>
</body>
</html>
I am pretty new to CSS, I have a simple case like the above. I would like to make the "title" and "some url" clickable but want to make description as non-clickable. Is there any way to do that by applying some CSS on the span so that whatever inside that span, it is not clickable.
My constraint is that, I do not want to change the structure of the div, instead just applying css can we make a span which is inside an anchor tag, not clickable ?

Actually, you can achieve this via CSS. There's an almost unknown css rule named pointer-events. The a element will still be clickable but your description span won't.
a span.description {
pointer-events: none;
}
there are other values like: all, stroke, painted, etc.
ref: http://robertnyman.com/2010/03/22/css-pointer-events-to-allow-clicks-on-underlying-elements/
UPDATE: As of 2016, all browsers now accept it: http://caniuse.com/#search=pointer-events
UPDATE: As of 2022, browsers behavior may have changed, another option can be:
a {
pointer-events: none;
}
a span:not(.description) {
pointer-events: initial;
}

Not with CSS. You could do it with JavaScript easily, though, by canceling the default event handling for those elements. In jQuery:
$('a span:nth-child(2)').click(function(event) { event.preventDefault(); });

CSS is used for applying styling i.e. the visual aspects of an interface.
That clicking an anchor element causes an action to be performed is a behavioural aspect of an interface, not a stylistic aspect.
You cannot achieve what you want using only CSS.
JavaScript is used for applying behaviours to an interface. You can use JavaScript to modify the behaviour of a link.

In response to piemesons rant against jQuery, a Vanilla JavaScript(TM) solution (tested on FF and IE):
Put this in a script tag after your markup is loaded (right before the close of the body tag) and you'll get a similar effect to the jQuery example.
a = document.getElementsByTagName('a');
for (var i = 0; i < a.length;i++) {
a[i].getElementsByTagName('span')[1].onclick = function() { return false;};
}
This will disable the click on every 2nd span inside of an a tag.
You could also check the innerHTML of each span for "description", or set an attribute or class and check that.

This is the simplest way I would have done it. Without bordering about CSS or javascript :
<html>
<head>
</head>
<body>
<div>
<p>
<a href="http://www.google.com">
<span>title<br></span>
</a>
<span>description<br></span>
<a href="http://www.google.com">
<span>some url</span>
</a>
</p>
</div>
</body>
</html>
You can replace the tag with anything you want.

Yes you can....
you can place something on top of the link element.
<!DOCTYPE html>
<html>
<head>
<title>Yes you CAN</title>
<style type="text/css">
ul{
width: 500px;
border: 5px solid black;
}
.product-type-simple {
position: relative;
height: 150px;
width: 150px;
}
.product-type-simple:before{
position: absolute;
height: 100% ;
width: 100% ;
content: '';
background: green;//for debugging purposes , remove this if you want to see whats behind
z-index: 999999999999;
}
</style>
</head>
<body>
<ul>
<li class='product-type-simple'>
<a href="/link1">
<img src="http://placehold.it/150x150">
</a>
</li>
<li class='product-type-simple'>
<a href="/link2">
<img src="http://placehold.it/150x150">
</a>
</li>
</ul>
</body>
</html>
the magic sauce happens at product-type-simple:before class
Whats happening here is that for each element that has class of product-type-simple you create something that has the width and height equal to that of the product-type-simple , then you increase its z-index to make sure it will place it self on top of the content of product-type-simple. You can toggle the background color if you want to see whats going on.
here is an example of the code
https://jsfiddle.net/92qky63j/

CSS relates to visual styling and not behaviour, so the answer is no really.
You could however either use javascript to modify the behaviour or change the styling of the span in question so that it doesn't have the pointy finger, underline, etc. Styling it like that will still leave it clickable.
Even better, change your markup so that it reflects what you want it to do.

Using CSS you cannot, CSS will only change the appearance of the span. However you can do it without changing the structure of the div by adding an onclick handler to the span:
<html>
<head>
</head>
<body>
<div>
<a href="http://www.google.com">
<span>title<br></span>
<span onclick='return false;'>description<br></span>
<span>some url</span>
</a>
</div>
</body>
</html>
You can then style it so that it looks un-clickable too:
<html>
<head>
<style type='text/css'>
a span.unclickable { text-decoration: none; }
a span.unclickable:hover { cursor: default; }
</style>
</head>
<body>
<div>
<a href="http://www.google.com">
<span>title<br></span>
<span class='unclickable' onclick='return false;'>description<br></span>
<span>some url</span>
</a>
</div>
</body>
</html>
