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 want to edit the "p" content which is inside the content div on my shopping cart page.
As the content div appears on every page, I don't wish to just go for "content + p"
Is there an attribute I can use that will "select all p tags in the div above cart-module"
<div class="content">
<p>The content I want to edit<./p>
<div class="cart-module">
<div class="cart-total">
Also, is there a problem with attribute rules slowing down the pages?
If the structure is always as you describe in you question then you can go with the first child selector:
.content > p:first-child {
background-color: red;
}
wich will get the p inside the content only if it is in the first place inside of it.
Regarding your second question, it will always depend on how and how many attributes you use on each page. The attribute selectors are slower than the ids or classes, because the latter are indexed by the browsers, just for this reason. Anyway, if you don't use them massively surely you won't notice the difference.
Of course, if you have access to modify the html structure the easiest would be to add a class to the p tags you want to select...
It's not possible with pure CSS.
If you want to style "all p tags in the div above cart-module", do some JQuery instead.
First, define a piece of CSS:
.my-custom-css {
color: chucknorris;
}
Then use JQuery prevAll()
$(".cart-module").prevAll().addClass("my-custom-css");
// Or do something with p tag
$(".cart-module").prevAll().find("p").addClass("my-custom-css");
// Edit content
$(".cart-module").prevAll().find("p").text("Thank God It's Friday");
Oh you want to modify something like structure or content of those "all p tags in the div above cart-module", just do the same with prevAll().
I have the top bar of my page set up as follows: Home | Contact Us etc..
It lies within a p tag inside a div id.
How would i go about setting up the :hover css on each link without having to separate them into different classes such as how I have them at the moment. Is it possible?
I don't think i used the correct css because i couldn't position them correctly without having to use different padding parameters for each class which makes the spacing look inaccurate.

html:
<div id="topinfo">
<div class="home"><p>Home |</p></div>
<div class="about"><p>About |</p></div>
<div class="contactUs"><p>Contact Us |</p></div>
<div class="map"><p>Map |</p></div>
</div><!--/topinfo tag-->
css:
.home p{padding-right:250px;}
#topbar .home p:hover{color:rgba(255,255,255,1)}
Is there an easier way to do this that is not so tedious. This method also causes the divider to have the hover effect which is not desirable.
The best way of defining menus in a page is to use "ul" and "li" tags. But if you still want to use with tag you have to use it this way:
`Home
About
contact
.home_link, .about_link, .contact_link{color: red;}
.home_link:hover, .about_link:hover, .contact_link:hover {color: blue;}`
I would give them all the same class, say topitem, and use a rule like this:
.topitem:hover p {
color:rgba(255,255,255,1);
cursor:pointer;
}
Although really, I would get rid of the interior <p> tag and reduce the selector to .topitem:hover – the text is already wrapped in a <div>, so why wrap it again? (But see Zinnia's note about the convention of using <ul> and <li> instead of nested <div>s.)
I have these divs that I'm styling with .tocolor, but I also need the unique identifier 1,2,3,4 etc. so I'm adding that it as another class tocolor-1.
<div class="tocolor tocolor-1"> tocolor 1 </div>
<div class="tocolor tocolor-2"> tocolor 2 </div>
<div class="tocolor tocolor-3"> tocolor 3 </div>
<div class="tocolor tocolor-4"> tocolor 4 </div>
.tocolor{
background: red;
}
Is there a way to have just 1 class tocolor-*. I tried using a wildcard * as in this css, but it didn't work.
.tocolor-*{
background: red;
}
What you need is called attribute selector. An example, using your html structure, is the following:
div[class^="tocolor-"], div[class*=" tocolor-"] {
color:red
}
In the place of div you can add any element or remove it altogether, and in the place of class you can add any attribute of the specified element.
[class^="tocolor-"] — starts with "tocolor-".
[class*=" tocolor-"] — contains the substring "tocolor-" occurring directly after a space character.
Demo: http://jsfiddle.net/K3693/1/
More information on CSS attribute selectors, you can find here and here.
And from MDN Docs MDN Docs
Yes you can do this.
*[id^='term-']{
[css here]
}
This will select all ids that start with 'term-'.
As for the reason for not doing this, I see where it would be preferable to select this way; as for style, I wouldn't do it myself, but it's possible.
An alternative solution:
div[class|='tocolor'] will match for values of the "class" attribute that begin with "tocolor-", including "tocolor-1", "tocolor-2", etc.
Beware that this won't match
<div class="foo tocolor-">
Reference:
https://www.w3.org/TR/css3-selectors/#attribute-representation
[att|=val]
Represents an element with the att attribute, its value either being exactly "val" or beginning with "val" immediately followed by "-" (U+002D)
If you don't need the unique identifier for further styling of the divs and are using HTML5 you could try and go with custom Data Attributes. Read on here or try a google search for HTML5 Custom Data Attributes
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
