Hide radio button while keeping its functionality - html

I searched on SO and Google and I couldn't find anything related. Is there any way I can hide the radio button next to an image (that is used as a label for it) but still keep its functionality when clicking on the label?
I have tried several methods but it seems that using display:none or visibility:hidden makes the radio function useless.

I have tried several methods but it seems that using display:none or visibility:hidden makes the radio function useless.
But it works. Maybe you didn't set for attribute:
<input id=radio1 name=testradios type=radio><label for=radio1>radio1</label>
<br>
<input id=radio2 name=testradios type=radio><label for=radio2>radio2</label>
#radio1 {
display: none;
}
OR
#radio1 {
visibility: hidden;
}
Both hide radio button but label is still clickable and checks its radiobutton.

In Angular, display:none or visibility:hidden didn't work for me.
Instead, I used:
input[type=radio] {
opacity: 0;
}

document.getElementById('myId').addEventListener('click', function() {
alert(this.checked);
})
label {
display: inline-block;
}
label:before {
content: '';
background: url('http://placehold.it/350x150') no-repeat;
width: 30px;
height: 30px;
display: inline-block;
}
input {
display: none;
}
<input type="radio" id="myId">
<label for="myId"></label>

Just cover them with another div whose color matched with the background. This will hide the radio buttons and still your radio buttons will work on clicks of their labels. Hope that helps..

Is there a way to replace the default choose file icon with a custom image background for an input field?

Since I have a PWA i can only find tutorials for uploading images using the input field. That part is working but I'm trying to replace the default 'choose file' icon with a custom image.
Here is a pic of what I have:
I don't want the 'choose file' image to show up at all. Also there's a default wording 'No file chosen'. I just want the image that's in the background but I haven't found anything online to shows how to replace it.
.input_pic {
background-image: url("../../../assets/image/SpaghettiPlus2.png") !important;
background-repeat: no-repeat;
}
<div *ngSwitchCase="'false'">
<ion-input class="input_pic" type="file"
id="capture"
accept="image"
capture (change)="uploadFromFile($event, 'photo1')"></ion-input>
</div>
It's possible to style the choose button with ::file-selector-button, however, you can't do anything about the no file chosen text with this solution.
Well, you can, by setting color to transparent, but it's not perfect.
#browse::file-selector-button {
display: none;
}
#browse {
color: transparent;
}
#browse::before {
content: url('https://via.placeholder.com/150');
}
<input type="file" id="browse">
Another solution is to hide the entire input control and use a label to trigger the browse event of the input control.
label {
display: block;
width: 150px;
height: 150px;
background: url("https://via.placeholder.com/150");
cursor: pointer;
}
#browse {
display: none;
}
<label for="browse" title="click to browse file"></label>
<input id="browse" type="file"> </input>
Simply redirect the click on your image to the input, and hide the input completely:
document.querySelector("img").onclick = (evt) => {
document.querySelector("input").click();
};
input { display: none; }
img { cursor: pointer; }
<img src="https://picsum.photos/100/100">
<input type="file">

ionicons replace checkbox and radion buttons with icons

I am using Ionicons on a project and have replaced the standard images for radio and checkbox with these icons.The issue I have is the actual default items are showing through the Ionicons when rendered.
I have the following HTML:
<input type="checkbox"
name="client{!! $client->uuid !!}"
class="checkbox-icon ion-android-checkbox-outline-blank" checked>
I also have the following CSS:
.checkbox-icon:before,
.radio-icon:before {
visibility: visible;
font-size: 20px;
}
.checkbox-icon.ion-android-checkbox-outline-blank:checked:before {
content: "\f374"; // icon for selected
font-size: 20px;
color: $brand-primary;
}
.radio-icon.ion-ios-circle-outline:checked:before {
content: "\f120"; // icon for selected
font-size: 20px;
color: $brand-primary;
}
input[type=checkbox].checkbox-icon.ion-android-checkbox-blank,
input[type=radio].radio-icon.ion-record {
visibility: hidden;
}
But although the checkboxes/radio buttons behave correctly, I can see the standard item below the ionicon. Is this due to the icon having a transparent background?
I tried changing opacity to 100% but it did not help.
I have created the custom checkbox and by using the same concept you can create the radio button as well. For now I have created the normal (color change) checkbox but you can customize it as per your own requirements. Please follow the below mentioned link:

tabIndex doesn't make a label focusable using Tab key

I'm trying to replace checkbox/radio inputs with icons. For this, I need to hide the original checkbox/radio. The problem is, I also want the form to properly support keyboard input, i.e. let the input remain focusable by Tab key and selectable using Spacebar. Since I'm hiding the input, it cannot be focused, so instead, I'm trying to make its <label> focusable.
This documentation and various other sources led me to believe I can do that using tabindex attribute (corresponding to HTMLElement.tabIndex property). However, when I try to assign tabindex to my label, it remains as unfocused as ever, however much I try to Tab to it.
Why doesn't tabindex make the label focusable?
The following snippet demonstrates the issue. If you focus the input with your mouse and try focusing the label using Tab, it doesn't work (it focuses the following <span> with tabindex instead).
document.getElementById('checkbox').addEventListener('change', function (event) {
document.getElementById('val').innerHTML = event.target.checked;
});
<div>
<input type="text" value="input">
</div>
<div>
<label tabindex="0">
<input type="checkbox" id="checkbox" style="display:none;">
checkbox: <span id="val">false</span>
</label>
</div>
<span tabindex="0">span with tabindex</span>
(The JavaScript code just allows to see that clicking on the label properly (un)checks the checkbox.)
Why doesn't tabindex make the label focusable?
Short Answer:
Label is focusable.
TabIndex won't make any difference.
Welcome to the world of browser/agent inconsistencies.
tl;dr;
The label (Ref) element is very much focusable. Its DOM Interface is HTMLLabelElement which derives from HTMLElement (Ref) which in turn implements GlobalEventHandlers (Ref) and hence exposes the focus() method and onfocus event handler.
The reason you are unable to get hold of proper specification / reference document for labels focus behaviour, is because you might have been looking at HTML5 Specs. Interestingly, HTML5 refs do not state anything relating to that, which adds to the confusion.
This is mentioned in the HTML 4.01 Ref here: http://www.w3.org/TR/html401/interact/forms.html#h-17.9.1
Specifically near the end of section 17.9.1 and just before 17.10:
When a LABEL element receives focus, it passes the focus on to its
associated control.
Also, elsewhere (I am unable to get hold of that part of the ref) I have read that it depends on the implementing agent. (Don't take my word for that, am not too sure).
However, what it means is that when you focus a label (or a label received a focus), that focus is passed on to its associated labeleable control. This will not result in two different focuses, but one focus on the input (in your case a checkbox). Because of this behaviour, tabindex property cannot play a role.
There is also a test suite by W3C for website accessibility (WAAG) here: http://www.w3.org/WAI/UA/TS/html401/cp0102/0102-ONFOCUS-ONBLUR-LABEL.html which, discusses the implementation of onfocus and onblur for a label. Ideally a keyboard or an assistive technology that emulates the keyboard should implement this. But...
This is where the browser inconsistencies play their role.
This can be demonstrated by this example. Check the following snippet in different browsers. (I have tested it against IE-11, GC-39 and FF-34. All of them behave differently.)
Click the button "Focus Label"
It should focus the label, then pass the focus and highlight its associated checkbox outline in blue.
Chrome-v39 works. IE-v11 it doesn't (somehow html and body do respond to :focus). FF-v34 it works.
Talking about browser inconsistencies, try using the "access key" L. Some browsers will focus the checkbox whereas some will click it i.e. pass the action to it.
Here is a fiddle to test it: http://jsfiddle.net/abhitalks/ff0xds4z/2/
Here is a snippet:
label = $("label").first();
$("#btn").on("click", function() {
label.focus();
});
* { margin: 8px; }
.highlight { background-color: yellow; }
:focus {
outline: 2px solid blue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="txt" type="text" value="input" /><br />
<label for="chk" accesskey="L">Checkbox: </label>
<input id="chk" type="checkbox" /><br />
<input id="btn" type="button" value="Focus Label" />
Hope that clears up your doubts.
.
Your problem:
Now focussing (sic) on your original problem of not being able to focus a label, because you want to style a checkbox differently by placing an icon kind of thing in its place.
In order to do that, one option for you is to not hide it completely by doing a display:none;. Rather, make it 1x1 pixel and shove it under your icon. This way it will still receive focus naturally and yet be effectively hidden.
For example, if your icons are a checkmark and a cross, then change the position of the checkbox and make the icons out of ::before or ::after pseudo-elements on the label. That will cause the checkbox to still receive focus, and make the icon respond to that. That will give the apparent illusion of the icon taking the focus.

Since this old post is one of the top google results for html label tabindex I want to add my very simple working solution. As #Abhitalks mentioned in the accepted answer, the focus of a label is passed to it's associated control. So to bypass this behavior, just add a tabindex to the label and use event.preventDefault() in a focus EventListener.
#Heretic Monkey kind of had the right idea in his answer but you don't need a wrapper element to achieve this. You will, however, need to manually forward any required keystrokes (like spacebar) through.
For example:
'use strict';
let field = document.getElementById('hidden-file-chooser');
let label = document.querySelector('label[for=hidden-file-chooser]');
// prevent focus passing
label.addEventListener('focus', event => {
event.preventDefault();
});
// activate using spacebar
label.addEventListener('keyup', event => {
if (event.keyCode == 32) {
field.click();
}
});
#hidden-file-chooser {
display: none;
}
input[type=text] {
display: block;
width: 20rem;
padding: 0.5rem;
}
label[for=hidden-file-chooser] {
display: inline-block;
background: deepskyblue;
margin: 1rem;
padding: 0.5rem 1rem;
border: 0;
border-radius: 0.2rem;
box-shadow: 0 0 0.5rem 0 rgba(0,0,0,0.7);
cursor: pointer;
}
<input type="text" placeholder="Click here and start tabbing through ...">
<input id="hidden-file-chooser" type="file">
<label for="hidden-file-chooser" tabindex="0"> Select a File </label>
<input type="text" placeholder="... then shift+tab to go back.">
P.S: I used input[type=file] in my example because that's what I was working on when I ran across this issue. The same principles apply to any input type.
Edit: The following was a misreading of the spec:
Looking that the full
specification,
you'll see that there is something called tabindex focus
flag,
which defines if the tabindex attribute will actually make the field
"tabbable". The label element is missing from that list of suggested
elements.
But then again, so is the span element, so go figure :).
That said, yYou can make the label text focusable by wrapping the whole thing in an another element, or using some JavaScript to force the issue. Unfortunately, wrapping (here in an anchor) can men a fair amount of extra work in CSS and JS to get working like a normal label element.
document.getElementById('checkbox').addEventListener('change', function(event) {
document.getElementById('val').innerHTML = event.target.checked;
});
document.getElementsByClassName('label')[0].addEventListener('click', function(event) {
event.target.getElementsByTagName('label')[0].click();
event.preventDefault();
});
document.getElementsByClassName('label')[0].addEventListener('keypress', function(event) {
if ((event.key || event.which || event.keyCode) === 32) {
event.target.getElementsByTagName('label')[0].click();
event.preventDefault();
}
});
.label,
.label:visited,
.label:hover,
.label:active {
text-decoration: none;
color: black;
}
<div>
<input type="text" value="input">
</div>
<div>
<a class="label" href="#">
<label tabindex="0">
<input type="checkbox" id="checkbox" style="display:none;">checkbox: <span id="val">false</span>
</label>
</a>
</div>
<span tabindex="0">span with tabindex</span>
As previous posters said:
Label focus always goes directly to the input element.
Quite an annoyance if somebody has fancy (but fake) checkboxes, hiding the original ones, with an actual focus for keyboard navigation nowhere to be seen.
best solution I can think of: javascript.
Style-away the actual focus, in favor of a fake one:
input[type=checkbox]:focus {
outline: none;
}
.pseudo-focus {
outline: 2px solid blue;
}
and watch for changes on the (in many scenarios visibly hidden) original checkbox:
$('input[type=checkbox')
.focus( function() {
$(this).closest('label').addClass('pseudo-focus');
})
.blur( function() {
$(this).closest('label').removeClass('pseudo-focus');
});
Full jsfiddle here.
For input type radio or checkbox:
opacity: 0;
height: 0;
width: 0;
min-height: 0;
line-height: 0;
margin: 0;
padding: 0;
border: 0 none;
and the Js above does the trick sweetly.

IE 11 Bug - Image inside label inside form

In IE11, the following piece of code will check the radio button as expected:
<input type="radio" id="myRadio" />
<label for="myRadio">
<img src="..." />
</label>
Wrapping a <form> around the above will however break the functionality of the label.
This SO post offers a solution to the problem by styling the image with pointer-events:none, and the label as a block-level element.
While that should of course not even be necessary, it also disables the ability to handle mouse events.
It would be much appreciated if someone can offer a pure CSS solution to this problem.
PS:
One thing worth mentioning, is that in IE11, if the image is styled as a block-level element, then pointer-events seems to loose its effects.
My markup looks like this (classes and other superfluous attributes removed):
<li>
<label>
<figure>
<img>
</figure>
<div>
<label></label>
<input type="radio">
</div>
</label>
</li>
It's a bit messy because some of it is auto-generated by Drupal. It didn't work in IE 11, but I made it work by adding:
img {
pointer-events: none;
}
I didn't need to change anything else and I have no other special css-trickery that I can see.
As I answered previously in the referred question, there is a pure CSS way.
If your image is display: block that fix can still be used, even tho you have to add some more trickery. For example:
CSS:
label img{
display: block; /* requirement */
/* fix */
pointer-events: none;
position: relative;
}
/* fix */
label{
display: inline-block;
position: relative;
}
label::before{
content: "";
display: block;
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
z-index: -1;
}
HTML:
<form>
<label>
<input type="checkbox"> some text
<img src="http://placekitten.com/200/200" alt="kitten!">
</label>
</form>
Fiddle
If the problem is with click handlers on the image it self, you may be able to solve that with a wrapper element on the image instead (which maybe the label, so no extra element may be needed). (But for that I'd like to see a more specific example that you are trying to do.)
img {
pointer-events: none;
position: relative;
z-index: -1;
}
This solved it in my case.
The img will be placed behind the label but "shine through".
I hope it helps.
You can put the image in the background of the label..
<label for="myField1" ><img src="image1.jpg"></label>
becomes
<style>
#lblMyField1 {
background-image: url('image1.jpg');
background-position: center center;/* depend..*/
background-repeat: no-repeat;
}
</style>
<label id="lblMyField1" for="myField1" > </div>
This is a rather interesting find. I'll do a bit more research to determine whether or not I can identify a more root cause, but for the time being I have a couple suggestions.
Nest Your Input
<label>
<input />
<img />
</label>
This is a common convention used for associating inputs with labels. Given the input and the label are both inline, this doesn't affect the actual layout necessarily.
JavaScript Patch
Another option is to perform a click on the corresponding input when one didn't happen naturally. In this approach we setup a timeout to click after 100ms. Any click that happens otherwise will clear our timeout:
$("label[for]").each(function () {
var timeout;
var element = $("#" + $(this).attr("for"));
$(this).on("click", function () {
timeout = setTimeout(function () {
element.click();
}, 100);
});
element.on("click", function () {
clearTimeout(timeout);
});
});
Browsers that already work will clear the timeout, preventing a second click. Internet Explorer 11 will click via the timeout.
Demo: http://jsfiddle.net/CG9XU/
One caveat is that that solution only works for labels that were on the page when the case was ran. If you have forms coming in late (perhaps via ajax), you'll need to listen higher up on the DOM. The below example listens on the document level:
$(document).on("click", "label[for]", function () {
var timeout;
var element = $("#" + $(this).attr("for"));
timeout = setTimeout(function () {
element.click();
}, 100);
element.one("click", function () {
clearTimeout(timeout);
});
});
The label element accepts as its content type all phrasing elements, and this includes image elements. I'll keep looking into this, and will update this answer with any insight.
Here is a solution that worked for me using pointer-events:none without having to set my image to position:relative as I needed it to be position:absolute for my design.
HTML
`<form>
<input id="radio-button-action" type="radio" name="search" value="open">
<label for="radio-button-action">
<div class="img-wrapper">
<img src="images/image.jpg" alt="image">
</div>
</label>
</form>`
CSS
So in this example we have an image that needs to be position: absolute
img {
position: absolute
top: 10px;
right: 10px;
height: 25px;
width: 25px;
display: inline-block; /* can be block, doesn't matter */
}
Now set pointer-eventson the img-wrapper div
.img-wrapper {
position: relative /* this is required for this to work */
pointer-events: none /* this is what will make your image clickable */
}
It works with
img {
pointer-events: none;
}

Multicolored placeholder text

I need to create an HTML text input element that features multicolored placeholder text. All of the text should be gray except, but a closing asterisk should be red, as in:
This strikes me as a seemingly simple task that is actually a lot more complicated because of how browsers restrict our ability to style native input elements.
I have heard of people using CSS to override native input styles so they can use custom fonts, etc., but is there away to have two special text styles (gray and red)? Or do I need to use an alternative (non-native) input?
Try something like this: http://jsfiddle.net/vmuJm/
The trick: address the placeholder text, add a "required" class to required inputs, and use the :after pseudo element to add an appropriately colored asterisk.
[EDIT] It looks like this is only working for Webkit browsers.
I have a rather fun way to do this and seems to work great in all browsers.
(Works fine in IE 8+, chrome, and Firefox.)
What I am doing is using the spans I put inside of the label to act as the value text.
Here is the html structure,
<label><span class="title">Name<span class="symbol">*</span></span>
<input type="text" />
</label>
The css,
label {
position: relative;
}
label:hover span {
display: none;
}
input[type="text"]:focus, input[type="text"]:active {
z-index: 2;
}
label input[type="text"] {
position: relative;
}
.title {
color: gray;
position: absolute;
left: 5px;
top: 1px;
z-index: 1;
}
.symbol {
color: red;
}
Last here is the jQuery I wrote to not allow the span to hover over your input if the input is filled in.
$('input[type="text"]').blur(function() {
if( $(this).val().length >= 1) {
$(this).toggleClass('active');
}
else {
$(this).removeClass('active');
}
});
Here is a JSFIDDLE to play with.
