Can I write a CSS selector selecting elements NOT having a certain class or attribute?
(10 answers)
Closed 4 years ago.
I have this rule:
* {background-color:#ddd;font-family: Arial,Helvetica,sans-serif;font-size:13pt}
Unfortunately, it imposes the font-size on a < span > element. I want the span to continue to have no default rules so I can use it to change text color, etc.
My * rule has the lowest priority, which is good since * is used to set default values, which we want overridden easily. However, it applies to the span rule, which makes span erroneously include its styles. Span should be used to apply specific styles, not the default styles.
Use the :not pseudoselector to exclude span, as follows:
:not(span) {background-color:#ddd;font-family: Arial,Helvetica,sans-serif;font-size:13pt}

Difference in applying CSS to html, body, and the universal selector *?
(1 answer)
Closed 3 years ago.
I would like to ask what is the difference between *{} and body,html{}. It changes the view in the html and I want to have a broad knowledge about this. Thanks.
The wildcard (*) will apply the styling to every element found on your HTML page unless you give specific styling for that element. It overrides any possible inheritance for the set property because it is setting that default value for each individual element. If you want to change something in a section that has child elements then you will have to make that change for each child. This can be useful in a few cases (box-sizing is probably the most common use) but most of the time you will not want to use this. Depending on how heavily this is used, it can slow down your page load times.
Setting the styling with body/html allows for inheritance to still take place. Elements within the html/body will still show the styling found here if their default is set to inherit. This will still allow a closer parent to the child to override the styling. In CSS, the best option is to be more specific.
The *{} selector (Universal selectors) matches elements of any type. (MDN).
body,html{} select body and html elements.
Consider the following example:
* { /* Selects all elements */
color: blue;
}
html,
body { /* Selects html and body element */
color: green;
}
<html>
<body>Body</body>
<footer>footer</footer>
</html>
*{}
is a universal selector. It will implement the styling of all the elements. If you want to do some changes with styling of the particular element then you have to override it.
body,html{}
will do the same for you. But there is one scenario. If you want to inherit the properties from the parent then body,html{} is definitely going to play this role. It is used for the inheritance of properties

Is there a CSS parent selector?

Is there a way to make a CSS Selector that matches the following?
All OBJECT elements
which have a PARAM element inside of them
The selector
OBJECT PARAM
doesn't work, as it matches the PARAM, not the OBJECT. I'd like to apply { display:none } to the objects; it's useless to apply that to the PARAMs.
(I'm aware I could pull this off with jQuery - $("object param").closest("object") - and VanillaJS - document.querySelector("object param").closest("object") - but I'm trying to create CSS rules on a page.)
To select all OBJECT containing PARAM, in CSS:
OBJECT:has(PARAM)
To select all OBJECT having a direct child PARAM, in CSS:
OBJECT:has(> PARAM)
No, what you are looking for would be called a parent selector. CSS has none; they have been proposed multiple times but I know of no existing or forthcoming standard including them. You are correct that you would need to use something like jQuery or use additional class annotations to achieve the effect you want.
Here are some similar questions with similar results:
Is there a CSS parent selector?
CSS Parent/Ancestor Selector
Complex CSS selector for parent of active child
Only thing that comes even close is the :contains pseudo class in CSS3, but that only selects textual content, not tags or elements, so you're out of luck.
A simpler way to select a parent with specific children in jQuery can be written as (with :has()):
$('#parent:has(#child)');
Is there any way you could programatically apply a class to the object?
<object class="hasparams">
then do
object.hasparams

Is there a CSS parent selector?

Is there a way to write css so it would select a div above a selector you already known.
For example.
#modal .container .login{
//style
}
so the above code will look for an ID of modal > classname of container > classname of login.
And style the .login.
Now is is possible to have it go the reverse. So style the #modal only if it has a child of .login and .container
Thanks
Short answer? no. (in the current CSS spec) as already answered here.
Is there a CSS parent selector?
but, I can give you a little trick.
create a special CSS rule (a class) with your special styling for the 'parent'.
then, with JQuery, on document.ready, check for all the elements in the DOM who meets your requirement (in your case: has a child of some class), and dynamically add the special CSS class.
It's not a perfect solution, but can be helpful in some cases.

CSS select multiple descendants of another element
(3 answers)
Closed 9 years ago.
Is there a better way than this to select the elements with classes options OR inputs that are descendants of #height without selecting any elements with those classes that are not descendants of #height?
#height .inputs, #height .options
The #height seems redundant but #height .inputs,.options selects all the class="options" on the page, not just those descended from #height.
Nope, that's just how CSS is designed, and it's one of the reasons I use LESS CSS on all of my projects now. With LESS, you can structure your CSS more like JavaScript by nesting selectors. For example:
#height {
.inputs, .options {
/* properties */
}
}
metadept is absolutely correct. The comma is separating your selectors, and since you aren't specifying that you want the .options that are children of #height, it will target every element with the class .options on the page.
LESS CSS is a great tool to use; you may also want consider SASS - it just boils down to what you're more comfortable with.

css: the meaning of * mark
What does the symbol * mean in CSS3. As used in a code;
*{

this refers to all the elements and this particular code will make all the element's margin and padding as 0
It's basically a reset style. To cancel out differences in user agent/browser styles.
* is a general and CSS wildcard, the selector you show above selects all elements in a HTML document. It is commonly used in reset stylesheets and is sometimes referred to as a universal selector.
