I am currently working on integrating a dropdown menu into a webpage that already utilizes a global "select" style. Is there a method to instruct the new dropdown list to disregard the global styling? There are approximately 1 to 2 zillion existing dropdowns on the site that rely on the global style, so I would prefer not to make changes to the existing html code.
To change the styling of a specific element, you can assign a unique class or id to it and utilize the all property with a value of either unset or initial. This approach may have limited browser support.
For example:
<div class="ignore-css"><div>
And in your CSS:
.ignore-css{all:unset;}
finding a simple solution to your request can be challenging, but one method involves developing a CSS class that reverts all relevant properties for a particular element and its descendants to enhance consistency. You might find this resource helpful Element specific CSS reset
To override another style, you can use "!important" like this:
a {color: red !important}
You can also use a more specific selector to ensure your style is applied:
* // a=0 b=0 c=0 -> specificity = 0
LI // a=0 b=0 c=1 -> specificity = 1
UL LI // a=0 b=0 c=2 -> specificity = 2
UL OL+LI // a=0 b=0 c=3 -> specificity = 3
H1 + *[REL=up] // a=0 b=1 c=1 -> specificity = 11
UL OL LI.red // a=0 b=1 c=3 -> specificity = 13
LI.red.level // a=0 b=2 c=1 -> specificity = 21
#x34y // a=1 b=0 c=0 -> specificity = 100
#s12:not(FOO) // a=1 b=0 c=1 -> specificity = 101
For more information on specificity, refer to the documentation here.
UPDATE:
For instance:
If you have a global rule that sets the color of links as blue:
a {color: blue}
But you want your links to be red, then you should add the following rule:
a {color: red !important}
In case the global rule already includes "!important", you will need to use a more specific selector, such as:
body a {color: red !important}
One way to enhance your styling is by adding cascading styles such as:
#id1 .class1 select
Alternatively, you can use:
.class:width:200px !important
Using the "!important" declaration will prioritize the style you specify over any global styles. However, if you need to override it further, it may require a combination of both methods.
It would be best to streamline your selectors. What I suggest is...
<div class="newbox">
<a href="#">I want this to have a unique style.</a>
</div>
CSS:
div.newbox a
{
color: #888;
text-decoration: none;
}
Alternatively, you could simply...
<div class="universal-styles">
<div class="omit-styles">
<div class="vital-styles">
......
</div>
</div>
</div>
where
.universal-styles{
vertical-align: middle;
}
.omit-styles{
all:unset;
}
.vital-styles{
vertical-align:right !important;
}
My go-to approach in this scenario is to give the new element a distinct class; something like the following usually does the trick:
<select class=i-am-unique>
<!-- <option> elements in here -->
</select>
Then, in the stylesheet, I locate the global rule and utilize a :not() pseudoclass for differentiation:
select:not(.i-am-unique) {
/* apply global rules */
}
select.i-am-unique {
/* implement unique rules */
}
This method involves minimal adjustments to the code, requiring just one additional class in the HTML markup, an adjustment to a CSS selector, and a new declaration block for the unique element. You can find an illustrative example here.
Moreover, it's worth noting that :not() enjoys support from a broad array of browsers, including IE9+ and Safari 3.2+.
There is a straightforward solution available, which worked flawlessly for me using a basic CSS rule.
