i want to add a style (display:none) to hide a div element with the class "xclass" but only if it contains a link with the href "/somedir/somepage.php" is this doable with CSS or CSS3 selectors?
below is some example code for the div i wish to hide, it could appear anywhere inside a web page.
<div class="xclass">
<div>
<div>
<a href="/somedir/somepage.php">
</div>
</div>
</div>
No, this isn't possible. Due to the way browsers handle CSS selectors, you cannot select a parent element based on its children.
This might be doable with JavaScript. Here's a jQuery snippet:
$('.xclass').each(function() {
if ($(this).has('a[href="/somedir/somepage.php"]')) {
$(this).hide();
}
});

Normally, CSS works by matching element names in the HTML:p.heading1 {} affects all elements of type p with class heading1.
Is there a way to display an object/text that only exists as an attribute?
For example, this is my HTML:
<body var="text I want to insert">
<div class="titlepage">
<p class="titlepagetext">this should also be displayed</p>
The title page has a number of <p> children. In addition to them, I want to display the content of body/var on the title page.
You can probably consider CSS variables. The custom property will get inherited by all the elements inside the body and you can use pseudo element to display it where you want:
.titlepage:before {
content:var(--var);
}
<body style="--var:'text I want to insert'">
<div class="titlepage">
<p class="titlepagetext">this should also be displayed</p>
</div>
</body>
AH Formatter has an -ah-attr-from() extension function that will let you get the contents of an ancestor's attribute (see https://www.antennahouse.com/product/ahf66/ahf-ext.html#attr-from).
You could use -ah-attr-from() in a rule for .titlepagetext::before.
When you using css, you can't target parent. There is no way to get parent selector. And content: "" can apply only for pseudo-classes.
I have a web code generated by an aplication (built in angular). It is a menu choice where I need to hide some of them. It looks e.g. like this:
<div class=first>
<div class=second>
<a href=href1>
</div>
<div class=second>
<a href=href2>
</div>
<div class=second>
<a href=href3>
</div>
</div>
Now what I need is to hide the div which contains a element with href2.
I can hide the a element:
.first .second a[href="href2"] {display:none}
But I need to hide the whole div element. I thought:
.first .second < a[href="href2"] {display:none}
that doesn't work.
I KNOW THE JQUERY SOLUTION with has function. The problem is I can only adapt css files of the application. If i'm right I cannot use jquery in css file.
Please...any Idea how to do this ?
thanks a lot for help
best regards

At the moment there is (sadly) no way to adress the parent element with CSS.
I don't know your layout or CSS Code but maybe you can just structure your HTML-Code in a different way.
Edit
And now I understand your question...
To hide (for example) the 3th .second div you don't need to adress it from the child element but from the parent element.
What you are probably looking for are the nth selectors,
for instance: nth-child() or nth-of-type().
You can find more info here.
Also, you should probably take a look at the basics of HTML and CSS.
In your code you have not closed the <a> tags or wrapped the values of the attributes in quotation marks.
Wrong:
<div class=first></div>
Right:
<div class="first"></div>
To hide (for instance) the first element you could use the :first-child selector or the :nth-child() selector. Since you will probably use the nth-child() selector this would be:
.first > .second:nth-child(1) {
display: none;
}
I have a <div> classed as class="tooltip" which is normally hidden with display:none.
I would like the <div> to show with display:block when an area of my image-map is clicked. I am planning on using the :target pseudo-class.
Here is the simplified version of my code :
<img id="slot" class="single" src="slot.png" usemap="#slot"/>
<map name="slot">
<area
shape="poly"
coords="30,0,61,15,31,31,0,16"
alt="Slot"
href="#trigger-happy">
</map>
<div class="fixed-container">
<div class="tooltip">
Slot
</div>
</div>
As you can see, the trick is that the href is hidden away within the <area> tag. From what I understand, it is currently impossible to select a parent with pure CSS.
Would you have any suggestions on how to perform this task ? I'm not familiar with JavaScript, so a pure CSS answer would be ideal. I know I'll have to get down to JS eventually however, so a JS fix would also be acceptable if there is no other way.
It should be noted that I can already achieve similar results with the :hover pseudo-class, by applying it to the map tag. When using map:hover, the browser reacts perfectly. However, for actual clicking rather than hovering, I'm not sure I can just use <a> with <map>, it doesn't seem to work.
You are targeting #trigger-happy via href, therefore you would add id="trigger-happy" to the element .tooltip.
Here is a working example.
Updated HTML:
<div class="fixed-container">
<div id="trigger-happy" class="tooltip">
...
</div>
</div>
Use the :target pseudo class to style the targeted element, #trigger-happy.
The base CSS would look like this:
#trigger-happy {
display:none;
}
#trigger-happy:target {
display:block;
}
The downside to the :target approach is that once something is clicked, it is clicked. There isn't any toggling available with this option. I imagine you could use the checkbox hack if you wanted it to be toggleable, otherwise JS would be needed.
With the below HTML, how i can select the DIV depper (which has no children)?
I think that i can use nth-last-child but dont work because all divs has the last (and also the first)! :D
PD: Not is possible the use of the ID or CLASS property in the DIV deeper (because they are HTML existent files in web)
Html:
<div class="base">
<div>
<div>
<div>
<div>
<!-- recursive divs (quantity not defined...) -->
</div>
</div>
</div>
</div>
</div>
CSS selectors cannot look to the parent elements, sadly, so you can't see which elements don't have divs as children.
If you are using jQuery, you can do this to find the element:
$('.base :not(:has(*))').addClass('deepest');
Demo: http://jsfiddle.net/EhZax/
You'll have to use Javascript. Here's an example using jQuery:
$('.base *').filter(function(){
return ! $(this).find('> *').length;
});
See it here in action: http://jsfiddle.net/E6sec/
Update: If you want to, you could create your own :sterile selector. Here's an example:
jQuery.expr[':'].sterile = function(el) {
return ! el.children.length;
};
You could then just use it as you would any other pseudo selector:
$('.base :sterile');
Here's the fiddle: http://jsfiddle.net/FBw5q/
P.S. I used the native el.children since it's way faster than any of jQuery's methods. However, IE < 9 will include comments as children. If that concerns you, you can use jQuery's children() method.
You need Javascript for that. It's not possible with CSS only
I've got a DIV I want to hide, but I cannot give it a specific ID... actually I cannot change the text of the DIV, since it is retrieved from a database, but I can add some html before it AND I know the exact text content of the DIV.
It's something like:
<div class="this_div">content_of_this_div</div>
So, I thought that maybe looking for the specific content, then taking the div and incapsulating it in a hidden div could work... or something similar... any idea?
thanks
If you can insert other HTML around it then you can use another div to hide it
Using CSS and HTML
.hidden { display: none; }
...
<div class="hidden"><div class="this_div">content_of_this_div</div></div>
Using HTML and Inline CSS
<div style="display: none;"><div class="this_div">content_of_this_div</div></div>
Wrap it in your own div would seem most sensible.
<div id="mydiv">
<div class="this_div">content_of_this_div</div>
</div>
then hide your div:
document.getElementById("mydiv").style.display="none";
Or, use jQuery. If that is only instance of class, you could do
$(".this_div").hide();
If you just want to be able to select it without giving it a specific id, you can do a number of things. Make an empty div with an id before, then use the direct sibling selector:
#divid+div {}
or use many other css selectors to accomplish same
But I do reccomend the aforementioned external div technique over this
