I have a <select> box in a <form>, and when its value is other, I want elements that have the class .applicableSupportCase to be hidden. I am trying to do this with just CSS. What am I doing wrong?
CSS
.applicableSupportCase {
transition: transform 0.3s ease, opacity 0.3s ease;
}
#typeBox[value="other"] ~ .applicableSupportCase{
opacity: 0;
transform: scaleY(0);
}
HTML
<select class="contactField" id="typeBox">
<option value="supportCase" selected="selected">Support case</option>
<option value="other">Other</option>
</select>
<label class="applicableSupportCase">Device:</label>
There are more elements with the applicableSupportCase class, but you get the point.
Actually, the css attribute selector don't look at value in the way that you are thinking...
Though Javascript sees the value property as the selected option's value, CSS sees only the markup, and an select[value='something'] attribute selector would actually look for this:
<select value='something'>
Not for the <option> selected.
Through css-only you will not be able to change another element using the selected option because the <option> is nested to the <select> tag, and there's no parent navigation selection on css.
EDIT
You can, however, mock it up with javascript, and leave your css selector as it is. Just trigger the select's onchange event to set an attribute called value to the DOM select element:
See Working Fiddle Example
document.getElementById('typeBox').onchange = function() {
this.setAttribute('value', this.value);
};
This can't be done using a <select> item, however because of the pseudo class :checked states of checkboxes and radio buttons, you can accomplish what you wanted using those instead:
HTML
<input type="radio" id="supportCase" name="radios">
<label for="supportCase">Support Case</label>
<input type="radio" id="other" name="radios">
<label for="other">Other</label>
<br />
<label class="applicableSupportCase">Device:</label>
CSS
input[id=other]:checked ~ .applicableSupportCase {
visibility:hidden;
}
I used visibility, but you can change the attribute to whatever you want.
If you want an ease in and out, then create the same statement using the :not(:checked) pseudo class:
input[id=other]:not(:checked) ~ .applicableSupportCase {
//whatever ease(out) you want here
}
JSFiddle: http://jsfiddle.net/ja2ud1Lf/
I would use personally create another class for hidden objects (eg 'hiddenClass'), and use jquery similar to the following:
$( "#typeBox" ).change(function(){
if($("#typeBox").val()=="other")
{
$(".applicableSupportCase").each(function(){
$(this).addClass("hiddenClass");
});
}
});

I want to style a label of a select-tag in html. When the user didn't pick any
option, the color of the label should be white. If the user picked an option, the label should switch to white.
html code:
<label class="titel" for="titel">Titel:</label>
<select class="titel" name="titel">
<option value=""></option>
<option value="Proffessor">Prof.</option>
<option value="Doctor">Dr.</option>
</select>
css code:
label.titel{color: white;}
What i tried, but didn't worked:
select.titel:checked + label.titel{color: black;}
I searched and i found out, for this kind of tasks the :checked pseudoclass is helpful. I can change the label color of radio buttons or checkboxes, when checked but not the label of a select-tag when option is checked.
Thanks for your help in advance!
Edit: To make it more clear, as it mentioned #Rembrand Reyes in a comment "The drop down when blank will have Title displayed white, but when the user picks title, it will color the label black?"
As stated above in the comment by #Peter M, you can't select the previous sibling using "+". What you can do is make use of Javascript to add the CSS style for the label onchange of select option like shown below:
window.onload = function() {
var eSelect = document.getElementById('title');
var optOther = document.getElementById('title-label');
eSelect.onchange = function() {
optOther.style.color = 'black';
}
}
.titel
{
color: white;
}
<!DOCTYPE html>
<html>
<body>
<label class="titel" id="title-label" for="titel">Titel:</label>
<select class="titel" id="title" name="titel" selected="">>
<option value=""></option>
<option value="Proffessor">Prof.</option>
<option value="Doctor">Dr.</option>
</select>
</body>
</html>
The :checked pseudo selector only works with input radio and checkbox elements. It may work in some browsers when applied to the option element rather than the select, but as far as I'm aware there's no way to achieve what you're looking for across all browsers.
Might be possible with javascript though.
Is it possible to use a CSS selector to target an input that has a specific value?
Example: How can I target the input below based on the value="United States"
<input type="text" value="United States" />
Dynamic Values (oh no! D;)
As npup explains in his answer, a simple css rule will only target the attribute value which means that this doesn't cover the actual value of the html node.
JAVASCRIPT TO THE RESCUE!
Ugly workaround: http://jsfiddle.net/QmvHL/
Original Answer
Yes it's very possible, using css attribute selectors you can reference input's by their value in this sort of fashion:
input[value="United States"] { color: #F90; }
• jsFiddle example
from the reference
[att] Match when the element sets the "att" attribute, whatever the
value of the attribute.
[att=val] Match when the element's "att"
attribute value is exactly "val".
[att~=val] Represents an element
with the att attribute whose value is a white space-separated list of
words, one of which is exactly "val". If "val" contains white space,
it will never represent anything (since the words are separated by
spaces). If "val" is the empty string, it will never represent
anything either.
[att|=val] Represents an element with the att
attribute, its value either being exactly "val" or beginning with
"val" immediately followed by "-" (U+002D). This is primarily intended
to allow language subcode matches (e.g., the hreflang attribute on the
a element in HTML) as described in BCP 47 ([BCP47]) or its successor.
For lang (or xml:lang) language subcode matching, please see the :lang
pseudo-class.
css attribute selectors reference
It is possible, if you're using a browser which supports the CSS :valid pseudo-class and the pattern validation attribute on inputs -- which includes most modern browsers except IE9.
For instance, to change the text of an input from black to green when the correct answer is entered:
input {
color: black;
}
input:valid {
color: green;
}
<p>Which country has fifty states?</p>
<input type="text" pattern="^United States$">
Yes, but note: since the attribute selector (of course) targets the element's attribute, not the DOM node's value property (elem.value), it will not update while the form field is being updated.
Otherwise (with some trickery) I think it could have been used to make a CSS-only substitute for the "placeholder" attribute/functionality. Maybe that's what the OP was after? :)
As mentioned before, you need more than a css selector because it doesn't access the stored value of the node, so javascript is definitely needed. Heres another possible solution:
<style>
input:not([value=""]){
border:2px solid red;
}
</style>
<input type="text" onkeyup="this.setAttribute('value', this.value);"/>
Sure, try:
input[value="United States"]{ color: red; }
jsFiddle example.
You can use Css3 attribute selector or attribute value selector.
/This will make all input whose value is defined to red/
input[value]{
color:red;
}
/This will make conditional selection depending on input value/
input[value="United States"]{
color:red;
}
There are other attribute selector like attribute contains value selector,
input[value="United S"]{
color: red;
}
This will still make any input with United state as red text.
Than we attribute value starts with selector
input[value^='united']{
color: red;
}
Any input text starts with 'united' will have font color red
And the last one is attribute value ends with selector
input[value$='States']{
color:red;
}
Any input value ends with 'States' will have font color red
Refreshing attribute on events is a better approach than scanning value every tenth of a second...
http://jsfiddle.net/yqdcsqzz/3/
inputElement.onchange = function()
{
this.setAttribute('value', this.value);
};
inputElement.onkeyup = function()
{
this.setAttribute('value', this.value);
};
In Chrome 72 (2019-02-09) I've discovered that the :in-range attribute is applied to empty date inputs, for some reason!
So this works for me: (I added the :not([max]):not([min]) selectors to avoid breaking date inputs that do have a range applied to them:
input[type=date]:not([max]):not([min]):in-range {
color: blue;
}
Screenshot:
Here's a runnable sample:
window.addEventListener( 'DOMContentLoaded', onLoad );
function onLoad() {
document.getElementById( 'date4' ).value = "2019-02-09";
document.getElementById( 'date5' ).value = null;
}
label {
display: block;
margin: 1em;
}
input[type=date]:not([max]):not([min]):in-range {
color: blue;
}
<label>
<input type="date" id="date1" />
Without HTML value=""
</label>
<label>
<input type="date" id="date2" value="2019-02-09" />
With HTML value=""
</label>
<label>
<input type="date" id="date3" />
Without HTML value="" but modified by user
</label>
<label>
<input type="date" id="date4" />
Without HTML value="" but set by script
</label>
<label>
<input type="date" id="date5" value="2019-02-09" />
With HTML value="" but cleared by script
</label>
Following the currently top voted answer, I've found using a dataset / data attribute works well.
//Javascript
const input1 = document.querySelector("#input1");
input1.value = "0.00";
input1.dataset.value = input1.value;
//dataset.value will set "data-value" on the input1 HTML element
//and will be used by CSS targetting the dataset attribute
document.querySelectorAll("input").forEach((input) => {
input.addEventListener("input", function() {
this.dataset.value = this.value;
console.log(this);
})
})
/*CSS*/
input[data-value="0.00"] {
color: red;
}
<!--HTML-->
<div>
<p>Input1 is programmatically set by JavaScript:</p>
<label for="input1">Input 1:</label>
<input id="input1" value="undefined" data-value="undefined">
</div>
<br>
<div>
<p>Try typing 0.00 inside input2:</p>
<label for="input2">Input 2:</label>
<input id="input2" value="undefined" data-value="undefined">
</div>
Is there any way that i could add a background color after placing a content inside an input field? Just like what happens when an autocomplete works.
Thanks!
There are a few ways you could achieve this. You could make the input mandatory by adding the required attribute. Doing this means that as soon as the user enters anything into the field, it is now in the valid state and you can target it in your CSS using the :valid pseudo-class:
input:valid{
background:#ff9;
}
<input required>
Or, if you don't want to make the field mandatory and as others have suggested, you could set the new background-color when the field receives focus. To prevent it from reverting to its initial color when it loses focus, you will need to add a transition to the background, setting the transition-delay to some ridiculously high number when the input is in its normal state and resetting it to 0s when it is focused. Obviously, though, this change will occur whether or not the user actually enters anything in the field or not.
input{
transition-delay:9999s;
transition-property:background;
}
input:focus{
background:#ff9;
transition-delay:0s;
}
<input>
If neither of those options suit your needs then you will probably need to resort to using JavaScript to add or remove a class, depending on whether or not the value of the input is empty.
document.querySelector("input").addEventListener("input",function(){
this.value?this.classList.add("filled"):this.classList.remove("filled");
},0);
.filled{
background:#ff9;
}
<input>
Html
First name: <input type="text" name="firstname">
Css
input:focus {
background-color: yellow;
}
Demo in JsFiddle
Here is a solution with pure javascript
var input = document.getElementById("test");
input.addEventListener('input', function() {
if (input.value)
input.style.backgroundColor = '#90EE90';
else
input.style.backgroundColor = '#fff';
});
<input id="test" type="text" value="">
Add a Css class like
.myCSSClass
{
background-color:red;
}
Now using jquery on blur function you add this class
$("#myTextBox").on('blur',function(){
if($("#myTextBox").val()==""){
if($("#myTextBox").hasClass("myCSSClass")){
$("#myTextBox").removeClass("myCSSClass");
}
}
else
{
$("#myTextBox").addClass("myCSSClass")
}
});
Using Jquery,
$( "#target" ).blur(function() {
$( "#target" ).css('background-color','red');
});

Just wanted to know if anyone knew a way I can select and style the html tag directly after looking for :checked in css.
#btnControl:checked ??? html {
overflow: hidden;
}
Any feedback will be greatly appreciated! : )
Best, Jonathan
You can't select parent using CSS. But you can use class to do this work. Use javascript to add/remove class to element. When checkbox checked, add class to html and when checkbox unchecked, remove class of html.
var checkbox = document.getElementById("checkbox");
var html = document.getElementsByTagName("html")[0];
checkbox.addEventListener("change", function(){
if (checkbox.checked)
html.classList.add("checked")
else
html.classList.remove("checked")
});
html.checked {
background: orange;
}
<label for="checkbox">Click on checkbox</label>
<input id="checkbox" type="checkbox" />
