target div with a checkbox - html

I have a checkbox which hides/shows a div. It works when I put the checkbox directly above the div. When I place the checkbox somewhere else in the page (for better usability) it doesnt't work. Is there a way to target a certain div to make the checkbox work from everywhere on the page?
Here is the HTML-code:
<input type="checkbox" id="toggle-result" checked="checked"> </input>
CSS:
input[type=checkbox]:checked ~ div {
display: none;
}

Using CSS, you can select child elements and adjacent elements, so what you are trying to do will work if div is placed right after the checkbox but if you want to make it work when div is somewhere else(above the checkbox), you need to use JavaScript, if it's after, you can use + to select adjacent element or nested adjacent element
Demo
<input type="checkbox" />
<div>Toggle Using CSS</div>
input[type=checkbox]:checked + div {
display: block;
}
div {
display: none;
}
Targetting div which is farther away somewhere (But not before the checkbox) like this
Demo 2
input[type=checkbox]:checked + a + .blah .target {
display: block;
}
.target {
display: none;
}
<input type="checkbox" />
Dummy Link
<div class="blah">
<div class="target">Complicated Selector, Isn't It?</div>
</div>
Explanation : input[type=checkbox]:checked + a + .blah .target Over
here we select the checkbox which is in a checked state, and than we
chain this by selecting the adjacent element which is an anchor tag,
and than we select another adjacent element which is adjacent to a
tag which is div with a class .blah, and than we select nested child element with a class .target
Using jQuery To Do (Doesn't matter where the target element is) Demo 3
<input type="checkbox" id="checkme" />
Dummy Link
<div id="show_on_check" style="display:none">
This content should appear when the checkbox is checked
</div>
$(document).ready(function() {
$('#checkme').change(function() {
$('#show_on_check').toggle();
});
});

input[type=checkbox]:checked ~ div {
display: none;
}
Will select every div element that is preceded by a input that is checked. The reason why it probably breaks is because the input is not preceding the div (Like you state in your question)

Use the element IDs in your selectors:
<input type="checkbox" id="toggle-result" checked="checked"/>
<div id="myDiv">showme</div>
<style>
#toggle-result:checked ~ #myDiv {
display: none;
}
</style>

Label's color changes when you are typing in the login field?

I want to make the same login effect than Twitter.
On twitter.com/login, you see that when you are typing in the text area, the grey color of the label "Phone, email, or username" or "Password" changes to blue.
So I've tried to make input:focus label {color: blue;}
But it doesn't work, I don't know why.
try using the general sibling selector like this
input:focus ~ label{
color: #0000ff;
}
Note that this code assumes input and label are siblings
Your code doesn't work because what you wrote basically says: "if I focus my input, put this css on my label which is a child of input". Now I'm assuming since this wouldn't be valid html, your label is not a child of your input.
The answer #arnavpanwar99 provided is correct, usually your input and label are siblings like this:
<div>
<label>My Label</label>
<input type="text" />
</div>
unfortunately, the sibling selector only works from left to right, meaning that something like this: input:focus ~ label would once again not work, since it goes once again from left to right (and the label is on the left side of your input, therefore the code is not affecting it).
Now if we switch positions, it would work:
div {
margin-bottom: 5px;
}
label {
color: grey;
}
input:focus ~ label {
color: red;
}
<div>
<input type="text" />
<label>My Label</label>
</div>
But unfortunately, now the label is on the wrong side.
The trick is, to use css (in my case I just used float: left but you can basically do everything you want to make it look right) to fix the appearance, while still using the "wrong" html setup:
div {
margin-bottom: 5px;
}
label {
color: grey;
}
input:focus ~ label {
color: red;
}
.pullLeft {
float: left;
}
<div>
<input type="text" />
<label class="pullLeft">My Label</label>
</div>
Set a class on a surrounding div and use :focus-within on that div followed by label to change the color of the label.
The reason why this works is because instead of looking for child elements of input, it checks if something is being focused within the surrounding div.
.input-group:focus-within label {
color: red;
}
<div class="input-group">
<label>My Label</label>
<input type="text" />
</div>

Click on image, change a text's background

I'm using a hack from this answer to make an image to resize on click (the checkbox method). It works fine. However, when I try to also apply a css style on a text on image click, it doesn't work:
<html>
<body>
<input type="checkbox" id="img-box"/>
<label for = "img-box">
<img src="http://www.al-van.org/AV/Manners_files/greeneyedcat.jpg"/>
</label>
<p id="some-text">
some text
</p>
</body>
</html>
#img-box:checked + label > img {
width: 100px;
}
#img-box:checked + p {
background-color: red;
}
What is my mistake here and how should I fix it?
The jsfiddle: https://jsfiddle.net/eus18r3h/
The input element with the id "img-box" is not a direct sibling to the p tag. #img-box:checked + p would only style a p tag which is directly next to the input, you have a label in between.
This would be the selector you are looking for '#img-box:checked + label + p'
You have used the adjacent sibling combinator (+) for your paragraph tag, but it only works if you have one element after another. So since you have the label tag in between, it doesn't work. If you just replace the + with the general sibling combinator ~ the code should work.
#img-box:checked ~ p{
background-color: red;
}

How can I change the content of a div using check boxes

I am trying to have a checkbox change the content of a div but if the content isn't together (in the same div), then it will not work.
HTML:
<div>
<input type="checkbox" id="check">
<label for="check">Hello</label>
</div>
<div class="check"></div>
CSS:
.check:before {
display: block;
width: 100px;
height: 100px;
background: red;
content:'';
}
input:checked ~ .check:before {
content:'Content';
}
JSFiddle: https://jsfiddle.net/pgkwn4j6/
In your example one thats working is using "input:checked ~ .check:before" which selects "check" class div that is preceeding right after the input that is checked(sibling elements).
When you the put the label and input in a different div tag you need to select parent`s sibling which is not possible through css.
You can do it through Jquery.
CSS: how to select parent's sibling
above question showcases very similar problem you are having.
It does not work because it is not in the same div, in css you can not manipulate any element outside the parent element. To be able to manipulate an element outside you have to use jquery. Here your JSfiddle correct link:
JSFiddle Correct
$(document).ready(function(e) {
$('input#check').click(function(){
$('.check').toggleClass('show-content');
});
});

CSS transition on div triggered by inner checkbox

I have the following simple example where I animate the position of a given div through CSS's transition directive (http://jsfiddle.net/rtubio/dmhqjhd3/):
<input type='checkbox' id='toggle' class='toggle' />
<label for='toggle'></label>
<div id='area' class='area'>
<div id='area-title' class='area-title'></div>
</div>
... and I have the associated CSS code (see the JSFiddle) that animates the translation of the div -50px towards the bottom of the page whenever the label of the checkbox is clicked. If I move the checkbox+label to the inside of the div that I am trying to animate:
<div id='area' class='area'>
<div id='area-title' class='area-title'>
<input type='checkbox' id='toggle' class='toggle' />
<label for='toggle'></label>
</div>
</div>
... the animation stops working (see this second JSFiddle with the non-working example: http://jsfiddle.net/rtubio/k5o0uggu/). I have been looking for possible incompatibilities, but I have found none.
Does CSS have any restriction for this case?
Yes, CSS has a restriction that sibling combinators (+ and ~) can 'see' only following siblings of DOM element, i.e. elements that are direct children of the parent of given element and come later in the source order than this element. CSS can't select ancestors of the element. So you have to leave your checkbox outside and before .area to keep it possible to control .area by :checked state of the checkbox.
But since your checkbox is invisible and label transfers the clicks to it regardless its position in the DOM, you can move only label inside .area and modify your selectors respectively, e.g.
.toggle + div label {
text-align: center;
display: block;
position: relative;
}
.toggle + div label:after {
content: '(hide)';
}
.toggle:checked + div label:after {
content: '(show)';
}
See edited fiddle
Your problem is .toggle:checked ~ .area as you have placed .toggle within .area it has nothing to change the position on if you place another div below add a class and change the css to
.toggle:checked ~ .newclass
everything should work

toggling styles on label (active/focus) for input field with css only

Wondering whether if there is a css-only way to perform to toggle styles on the corresponding label on input's focus.
So far I have:
$(document).on('focus active', 'input',function(){
$('label[for='+$(this).attr('id')+']').addClass('active');
});
$(document).on('blur', 'input',function(){
$('label[for='+$(this).attr('id')+']').removeClass('active');
});
HTML:
<div class="row">
<label for="contact_form_mail">Email</label>
<input id="contact_form_mail" name="contact_form_mail" type="email" placeholder="Your e-mail address...">
</div>
And CSS:
.active{ color:red; }
Edit: I am surely aware of the child and sibling selectors "workarounds", but rearranging clean markup for the pure sake of styling seems not right, so if there is another pure css way this answer wins!
http://jsfiddle.net/fchWj/3/
Try this way:- Place your label after input and float it left. And apply siblings.
Html
<div class="row">
<input id="contact_form_mail" name="contact_form_mail" type="email" placeholder="Your e-mail address...">
<label for="contact_form_mail">Email</label>
</div>
CSS
label {
float:left;
}
input:focus + label {
color:red;
}
Demo
This is a hack to get the adjacent sibling selector work as it applies only on the following element and not the preceding one. ~ will select all the adjascent siblings after this element. So if you are having different .row for each section of inputs then use +.
If you are willing to switch elements, than here you go
Demo
<div>
<input type="text" />
<label for="e_mail">E-Mail</label>
</div>
label {
float: left;
margin-right: 5px;
}
input[type=text]:focus + label {
color: red;
}
Explanation: We are using + adjacent selector here, so when the textbox is focused, we select the label tag and apply color red
Note: Don't forget to clear floats ;)
It's possible with CSS only, without switching the order of the label and input. You can use a :focus-within CSS pseudo-class on the parent element, which applies to elements, that has a child element with the focus.
In your example, you could use the following:
.row:focus-within label {
color: red;
}
Note, that this pseudo-class is relatively new, so only modern browsers support it.
There is, but only if you place the label after the input.
<input name="field" type="text" />
<label for="field">Label Here</label>
input:focus + label{
color: red;
}
Now if you want the label to be placed before it, then you need to do some css styling with position absolute to place the label before the input field, then add some margin left on the input to move it to the right.
<div>
<input name="field" type="text" />
<label for="field">Label Here</label>
</div>
div{
position: relative;
}
input{
margin-left: 40px;
}
label{
position:absolute;
left:0;
}
This give you label on top of input, highlight label while input focus.
HTML
<div class="row">
<input id="contact_form_mail" name="contact_form_mail" type="email" placeholder="Your e-mail address...">
<label for="contact_form_mail">Email</label>
</div>
<code>
.row{
display:flex;
flex-direction:column-reverse;
align-self:flex-start;
}
.row input:focus{
border: 1px solid red;
}
.row input:focus+label{
color:red;
}
</code>
First we can use a selector that matches a label immediately followed by the input tag (input:focus + label). But there is still the problem, that the label follows after the actual input field. If one would like to have it above the text input we need to switch the positions of the controls. This can be done with a CSS pseudo-table.
<div class="pseudo-table">
<input id="yourname" name="yourname" type="text" placeholder="Name...">
<label for="yourname">Name</label>
</div>
The style for the artifical table is...
.pseudo-table { display: table; }
With this in place we could transform the label e.g. to a table-header-group:
label { display: table-header-group; }
and the input field to a table-row-group:
input { display: table-row-group; }
In combination with our followed by selector we're done and it looks right:
input:focus + label {
color:red;
font-weight: bold;
}
For a demo please see this Fiddle
HTH
There is no selector to match a preceding element...
This matches a label immediately followed by an input tag.
input:focus + label {
color: red;
}
