I know can control the display of a single class by using the following CSS:
.some-random-class{
display: none;
}
input[type=checkbox]:checked ~ .some-random-class{
display: flex;
}
I understand that this code controls the display of any object with the class of "some-random-class" that is a sibling of whatever checkbox is checked. If I have 3 classes I want to control the display of, I can do so with 3 separate input "functions" addressing each class individually. What I can't quite seem to figure out is how to control multiple classes in with the same "function" and control classes that are not in the same generation as in the following HTML:
<div>
<input type="checkbox">
<div class="first-class">
stuff to hide
</div>
<div class="second-class">
stuff to hide
<input type="checkbox">
<div class="third-class">
stuff to hide
</div>
</div>
</div>
When I try to control all three using what I think logically should work, it breaks the whole thing.
The following CSS is what I thought SHOULD work, however doesn't:
input[type=checkbox]:checked ~ .first-class ~ .second-class ~ .third-class {
display: flex;
}
Is this even possible, or am I asking too much of CSS?
If what I want to accomplish is possible, what am I not understanding about the above function?
You need to separate each rule with , , not just concatenate them with ~, because that only can select a single element.
input[type=checkbox]:checked ~ .first-class,
input[type=checkbox]:checked ~ .second-class,
input[type=checkbox]:checked ~ .third-class {
color: red;
}
input[type=checkbox]:checked ~ .third-class {
color: blue;
}
<div>
<input type="checkbox">
<div class="first-class">
stuff to hide
</div>
<div class="second-class">
stuff to hide
<input type="checkbox">
<div class="third-class">
stuff to hide
</div>
</div>
</div>
span{
text-align: justify;
}
<input type="checkbox" name="type"><span>Excessive Reinforcement</span><br>
I want to align the label for excessive reinforcement checkbox like image2
For example
Thanks in advance
First of all use <label> instead of <span>.
If we use bootstrap we generally manage this with classes but here if we talk about custom css this can be a solution.
label{
text-align: justify;
float: left;
line-height: 20px;
}
input{
float:left;
}
<input type="checkbox" id="check" name="type"><label for="check">Excessive<br>Reinforcement</label><br>
Above i added id in checkbox and for in label so that checkbox will be selected on click of label also.
If you can change the HTML
The best and new method to use checkbox is
<label><input type="checkbox" name="type">Excessive Reinforcement</label>
span {
text-align: justify;
}
.make-table {
display: table-cell;
/* make it behave like table-cell. so that they fall beside each other. */
}
<div class="any-class">
<label><span class="make-table"><input type="checkbox" name="type"></span>
<span class="make-table">Excessive<br> Reinforcement</span>
</label>
</div>
<hr>
<div style="color:red">Wrap it inside any-class and align as you want.
<br>I added LABEL tag, so that, even if your user clicks on the text, the checkbox will work.</div>
Make this simple change!
This is one way of doing it:
<label for="type-1">
<input id="type=1" type="checkbox" name="type"> Excessive Reinforcement
</label><br>
When using input elements, you should always provide a label with the for attribute assigned the id of the input element. And also make sure the input element ids are unique.
I want to target a div when a checkbox is checked. Can anybody tell me how can I target an outer div when checkbox is checked?
if($('.checkboxClassName').checked) {
$(this).parent();
}
It will target the parent div that the checkbox is inside, you can use more .parent() if tour target is not inside the same parent.
example: if your code is like this:
<div class="container">
<div class="target"></div>
<div class="parent">
<div class="checkboxDiv">
<input type="checkbox">
</div>
</div>
</div>
and you want to target the div.target you'll need the code like this:
if($('.checkboxClassName').checked) {
$(this).parent().parent().parent().find(".target").css('background','magenta');
} else {
$(this).parent().parent().parent().find(".target").css('background','cyan');
}
those parents will work like this: $(this).parent() = targeting div.checkboxDiv
$(this).parent().parent() = targeting div.parent
...
Note how this jsFiddle highlights the usage in a very simple way:
A check box is focused upon (checked).
The CSS style :checked catches this occurrence and applies a CSS style to the div contents.
The div can be another element you want, just make sure you play around with the code and adapt it to your needs. Let us know if you need any more help!
Source: :checked
HTML
<input type="checkbox" id="ossm" name="ossm">
<label for="ossm">CSS is Awesome</label>
CSS
input[type=checkbox] + label {
color: #ccc;
font-style: italic;
}
input[type=checkbox]:checked + label {
color: #f00;
font-style: normal;
}
Edit: I thought you would like a reference to 'how' CSS works here:
Attribute Selector by value
Element plus Element
...and in general CSS selectors
I am trying to use "check box" to change color of element.
HTML:
<label for="toggle-1">I'm a toggle</label>
<input type="checkbox" id="toggle-1">
<div class="reklama">I'm controlled by toggle. No JavaScript!</div>
CSS:
.reklama {
color:Red;
}
input#toggle-1: checked ~ .reklama{
color:green;
}
U can find my demo here.
You can't have any spaces before the ":checked", so that it is directly connected to your id. This will work in your CSS
input#toggle-1:checked ~ .reklama{
Is there a solution to the problem illustrated in the code below? Start by opening the code in a browser to get straight to the point and not have to look through all that code before knowing what you're looking for.
<html>
<head>
<title>Input ID creates problems</title>
<style type="text/css">
#prologue, #summary { margin: 5em; }
</style>
</head>
<body>
<h1>Input ID creates a bug</h1>
<p id="prologue">
In this example, I make a list of checkboxes representing things which could appear in a book. If you want some in your book, you check them:
</p>
<form>
<ul>
<li>
<input type="checkbox" id="prologue" />
<label for="prologue">prologue</label>
</li>
<li>
<input type="checkbox" id="chapter" />
<label for="chapter">chapter</label>
</li>
<li>
<input type="checkbox" id="summary" />
<label for="summary">summary</label>
</li>
<li>
<input type="checkbox" id="etc" />
<label for="etc">etc</label>
<label>
</li>
</ul>
</form>
<p id="summary">
For each checkbox, I want to assign an ID so that clicking a label checks the corresponding checkbox. The problems occur when other elements in the page already use those IDs. In this case, a CSS declaration was made to add margins to the two paragraphs which IDs are "prologue" and "summary", but because of the IDs given to the checkboxes, the checkboxes named "prologue" and "summary" are also affected by this declaration. The following links simply call a javascript function which writes out the element whose id is prologue and summary, respectively. In the first case (prologue), the script writes out [object HTMLParagraphElement], because the first element found with id "prologue" is a paragraph. But in the second case (summary), the script writes out [object HTMLInputElement] because the first element found with id "summary" is an input. In the case of another script, the consequences of this mix up could have been much more dramatic. Now try clicking on the label prologue in the list above. It does not check the checkbox as clicking on any other label. This is because it finds the paragraph whose ID is also "prologue" and tries to check that instead. By the way, if there were another checkbox whose id was "prologue", then clicking on the label would check the one which appears first in the code.
</p>
<p>
An easy fix for this would be to chose other IDs for the checkboxes, but this doesn't apply if these IDs are given dynamically, by a php script for example.
Another easy fix for this would be to write labels like this:
<pre>
<label><input type="checkbox" />prologue</label>
</pre>
and not need to give an ID to the checkboxes. But this only works if the label and checkbox are next to each other.
</p>
<p>
Well, that's the problem. I guess the ideal solution would be to link a label to a checkboxe using another mechanism (not using ID). I think the perfect way to do this would be to match a label to the input element whose NAME (not ID) is the same as the label's FOR attribute. What do you think?
</p>
</body>
</html>
it's been resolved here:
https://stackoverflow.com/a/8537641
just do it like this
<label><input type="checkbox">Some text</label>
The best, to my mind, what you can do, is to rename all the checkboxes, by adding some prefix to their ids, for example input
<ul>
<li>
<input type="checkbox" id="input_prologue" />
<label for="input_prologue">prologue</label>
</li>
<li>
<input type="checkbox" id="input_chapter" />
<label for="input_chapter">chapter</label>
</li>
<li>
<input type="checkbox" id="input_summary" />
<label for="input_summary">summary</label>
</li>
<li>
<input type="checkbox" id="input_etc" />
<label for="input_etc">etc</label>
</li>
</ul>
This way you will not have any conflicts with other ids on a page, and clicking the label will toggle the checkbox without any special javascript function.
EDIT: In retrospect, my solution is far from ideal. I recommend that you instead leverage "implicit label association" as shown in this answer: stackoverflow.com/a/8537641/884734
My proposed, less-than-ideal solution is below:
This problem can be easily solved with a little javascript. Just throw the following code in one of your page's js files to give <label> tags the following behavior:
When a label is clicked:
If there is an element on the page with an id matching the label's for attribute, revert to default functionality and focus that input.
If no match was found using id, look for a sibling of the label with a class matching the label's for attribute, and focus it.
This means that you can lay out your forms like this:
<form>
<label for="login-validation-form-email">Email Address:</label>
<input type="text" class="login-validation-form-email" />
</form>
Alas, the actual code:
$(function(){
$('body').on('click', 'label', function(e){
var labelFor = $( this ).attr('for');
if( !document.getElementById(labelFor) ){
e.preventDefault(); e.stopPropagation();
var input = $( this ).siblings('.'+labelFor);
if( input )
input[0].focus();
}
})
});
Note: This may cause issues when validating your site against the W3C spec, since the <label> for attribute is supposed to always have a corresponding element on the page with a matching ID.
Hope this helps!
Simply put, an ID is only supposed to be used once on a page, so no they wouldn't design a workaround for multiple ID's on a single page which aren't supposed to exist.
To answer the rest of the question: no, the ID attribute is the only thing a label's 'for' attribute will look at. You can always use a JavaScript onclick event to fetch the input by name and change it, though that seems overly complicated when you can just fix your ID issue, which would make a lot more sense.
Maybe easy straightforward solution would be using uniqueid() php or other programming language alternative function.
Unlike the accepted answer, I agree with the solution proposed by FantomX1, generate a random id for every checkbox and use this id for the label associated to the checkbox.
But I would generate the random id using a uuid (see Create GUID / UUID in JavaScript?)
i was struggling with this today and thought i could share my result, because it seems there're no others in googles top-ranks. So here's my first Stack-Post (the trick is to stretch the checkbox over the other elements but keeping them clickable by using z-index):
