How to disable submit button & links on-click in pure CSS? - html

I have challenged myself to create a visually dynamic and interactive experience in HTML and CSS only (No Javascript). So far, I haven't come across any feature I needed that I couldn't do in pure CSS and HTML. This one is perhaps a bit more difficult.
I need to prevent the user from double-clicking<a>, <input type="submit"> and <button> tags. This is to prevent them double-submitting a form or accidentally making 2 GET requests to a URL. How can this be done in pure CSS? Even if we can't set disabled without JS, there should be some masking technique or combination of styles that can handle it here in 2020.
Here is a simple example of an attempt:
.clicky:focus{
display: none;
pointer-events: none;
}
test
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p id="down">target</p>
Unfortunately, this disables it before the actual click event is fired for some reason. Maybe anchors aren't the best way to test? I will continue to make further attempts.

One idea is to have a layer that come on the top of the element after the first click to avoid the second one.
Here is a basic idea where I will consider a duration of 1s between two clicks that you can decrease. Try to click the button/link and you will notice that you can click again only after 1s.
I am adding a small overlay to better see the trick
.button {
position:relative;
display:inline-block;
}
.button span{
position:absolute;
top:0;
left:0;
right:0;
bottom:100%;
z-index:-1;
animation:overlay 1s 0s; /* Update this value to adjust the duration */
transition:0s 2s; /* not this one! this one need to be at least equal to the above or bigger*/
}
.button *:active + span {
animation:none;
bottom:0;
transition:0s 0s;
}
#keyframes overlay {
0%,100% {
z-index:999;
background:rgba(255,0,0,0.2); /* To illustrate */
}
}
<div class="button">
<button>Click me</button>
<span></span>
</div>
<div class="button">
Click me
<span></span>
</div>

The first solution
The idea is to use radio button state by :checked to make modifications. We hide radio circle and when :checked for <a> make pointer-events: none; and for buttons with different types we hide them and show disabled ones.
div {
margin: 10px;
}
#radio0, .my-checkbox {
position: absolute;
height: 0;
width: 0;
opacity: 0;
}
#radio0 + a label {
cursor: pointer;
}
#radio0:checked+a {
pointer-events: none;
}
.btn-one,
.btn-two {
padding: 0;
}
.btn-one>label,
.btn-two>label {
padding: 1px 6px;
}
.my-checkbox:checked+.btn-one {
display: none;
}
.btn-two {
display: none;
}
.my-checkbox:checked+.btn-one+.btn-two {
display: inline-block;
}
<div>
<input id="radio0" type="radio" onclick="console.log('radio0 clicked!')">
<a href="#">
<label for="radio0">
Click the link!
</label>
</a>
</div>
<div>
<input type="radio" id="radio1" class="my-checkbox">
<button type="button" class="btn-one" onclick="console.log('radio1 clicked!')">
<label for="radio1">Click the button!</label>
</button>
<button type="button" class="btn-two" onclick="console.log('radio1 NOT clicked!')" disabled>
<label for="radio1">Click the button!</label>
</button>
</div>
<div>
<input type="radio" id="radio2" class="my-checkbox">
<button type="submit" class="btn-one" onclick="console.log('radio2 clicked!')">
<label for="radio2">Submit!</label>
</button>
<button type="submit" class="btn-two" onclick="console.log('radio2 NOT clicked!')" disabled>
<label for="radio2">Submit!</label>
</button>
</div>
The second solution
This one suits for links. The idea is to use :target. Targe element is hidden firstly. Then when is targeted use :target to pointer-events: none; of <a>.
#anchor {
display: none;
}
#anchor:target {
display: block;
}
#anchor:target+a {
pointer-events: none;
}
<div>
<span id="anchor"></span>
Click the link!
</div>

how to make hover effect last longer even after removing mouse

i am trying to make a home page for my browser
when i hover over stackoverflow many others divs(clickable links) become visible
but when i move my mouse to click over them the hover state is undone and i am unable to click them does anyone can give me general idea of how to deal with it , i want to make the hover affect stay even after removing the house for some time
.wrapper{
border:1px solid red;
}
label#stackoverflow:hover ~ a

opacity: 1;
height: auto;}
a{
transition: all 5s ease;
opacity: 0;
height: 0;}

</div>
Something along these lines should point you in the right direction.
When the a tag is inside the label tag, you are technically still hovering over the label when your cursor is over it's children.
a.subitem {
opacity: 0;
transition: all 0.5s;
}
label:hover a.subitem {opacity: 1}
<div>
<label>Stackoverflow <a class="subitem" href="#">SomeLink</a></label>
</div>

How to create a drop-down menu in HTML

The assignment I'm working on asks to create a dropdown menu such as the one in the link. How would i do this?
You could use details and summary HTML5 elements (if IE and Opera Mini are not a big concern; for those the below example will fallback gracefully)
<details>
<summary>Please fill out our optional survey</summary>
<p>What year are you in college?</p>
<label><input type="radio" name="clg" value="0"> Not yet there</label>
<label><input type="radio" name="clg" value="1"> Junior</label>
<label><input type="radio" name="clg" value="2"> Senior</label>
</details>
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/summary
http://html5doctor.com/the-details-and-summary-elements/
Find also other ways to Toggle an element
To recreate the above in JavaScript here's a ES6 example:
[...document.querySelectorAll('[data-details]')].forEach( el =>
el.addEventListener('click', () => {
document.querySelector(el.getAttribute('data-details')).classList.toggle('hide');
el.classList.toggle('open');
el.setAttribute('aria-expanded', el.classList.contains('open'));
})
);
[data-details] {
display: block;
width: 100%;
-webkit-appearance: none;
background: none;
border: none;
text-align: left;
font: inherit;
}
[data-details]:before { content: "\25ba"; speak: none; }
[data-details].open:before { content: "\25bc"; speak: none; }
.hide{ display: none; }
<button type="button" data-details="#d1" aria-describedby="d1" aria-expanded="false" >Summary 1</button>
<div id="d1" class="hide">CONTENT ONE</div>
<button type="button" data-details="#d2" aria-describedby="d2" aria-expanded="false">Summary 2</button>
<div id="d2" class="hide">CONTENT TWO</div>
As another answer pointed out, you can use the details and summary elements, but they are poorly supported, only usable in Chrome and Firefox, if you need a solution that works in IE, Edge, and Safari, you need to use javascript, thankfully, this is very simple.
<div id="summary" onclick="toggle();">Summary</div>
<div id="togglable" style="display:none;">Toggleable text</div>
<script>
var i=0;//Counter
function toggle(){//Function called when Summary is clicked
if(i%2===0){//Even number
document.getElementById("toggle").style.display="initial";//Make it visible
}else{//Odd number
document.getElementById("toggle").style.display="none";//Visible
}
i++;
if(i===2){
i=0;//Reset i to ensure it doesn't get too big
}
}
</script>

How to close this pure css popup with anywhere or outside click?

Here is the HTML Code, check out this fiddle for full working code -
https://jsfiddle.net/fmqgeqby/
<a class="" href="#popup1">Get a Quote</a>
<div id="popup1" class="myoverlay">
<div class="mypopup">
<h2>REQUEST A PHONE CALL</h2>
<a class="myclose" href="#">×</a>
Is there any possible solution for this to close popup, when user click outside of site?
Sorry the jsfiddle didn't work so I couldn't see it but can you change it to use bootstrap? Bootstrap's modal works very well.
If not, you could mimic some of what they're doing with your own code.
https://www.w3schools.com/bootstrap/bootstrap_modal.asp
One way to go with is using html labels with hidden checkbox. You will need two labels to be able to toggle the checkbox - one outside of the popup and another inside. Not the cleanest solution, but works:
HTML:
<label for="toggle">Get a Quote</label>
<input type="checkbox" id="toggle">
<div id="popup1" class="myoverlay">
<label for="toggle"></label>
<div class="mypopup">
<h2>REQUEST A PHONE CALL</h2>
<a class="myclose" href="#">×</a>
<div class="mycontent">
<p> Hello </p>
</div>
</div>
</div>
CSS:
input[type=checkbox] {
position: absolute;
left: -999em;
}
input[type=checkbox]:checked ~ #popup1 {
visibility: visible;
opacity: 1;
}
#popup1 label {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
z-index: 0;
}

Change color of span on focus of input in another span

I need to change the background color of a span using css when an input field in another span is focused.
<p class="some">
<span class="one">Name</span>
<span class="two"> <input type="text" name="fname"> </span>
</p>
Here is the css:
.one
{ background-color: red; }
I tried doing this:
.two:focus + .one
{background-color-black;}
but its not working.
Any help would be appreciated.
Thanks!
you can use :focus-within,
It worked for me.
This is a document https://developer.mozilla.org/en-US/docs/Web/CSS/:focus-within
.one { float: left; }
input { margin: 0 0 0 5px; }
.some:focus-within .one { background: red; }
<p class="some">
<span class="one">Name</span>
<span class="two"> <input type="text" name="fname"> </span>
</p>
If you do not mind elements order, try this snippet:
.one { float: left; }
input[name="fname"] { margin: 0 0 0 5px; }
input[name="fname"]:focus + .one { background: khaki; }
<p class="some">
<input type="text" name="fname"/>
<span class="one">Name</span>
</p>
Here is a fiddle
Using javascript:
Html:
<p class="some">
<span class="one">Name</span>
<span class="two"> <input type="text" name="fname" onfocus="changeColor()"> </span>
</p>
Javascript:
<script type="text/javascript">
function changeColor() {
document.getElementsByClassName("one")[0].style.backgroundColor="black";
}
</script>
Css:
.one
{ background-color: red; }
Another javascript solution, using classes, and also handles the input loosing focus:
function getFocus() {
var one = document.getElementsByClassName("one")[0];
one.className = one.className + " one-focused";
}
function looseFocus() {
var one = document.getElementsByClassName("one")[0];
one.className = one.className.replace("one-focused", "");
}
.one { background-color: red; }
.one-focused { background-color: black; }
<p class="some">
<span class="one">Name</span>
<span class="two"> <input type="text" name="fname" onfocus="getFocus()" onblur="looseFocus()"> </span>
</p>
This has some fairly obvious flaws, but works in this case. You may want to loop through all classes, or use id's instead of classes. If you are using jQuery then this becomes slightly simpler, but I have left this using standard javascript and only changing the background of the first element in the document.

CSS Hide some text with class and id

Hi I am trying to make a website with CSS and want to know if it is possible to hide the text according to language. We use an asp website and languages are English and French. For simplicity of the person who will document the FAQ, I am obliged to do html(No template and DB). I want to do a CSS code that it check if the languageCode is "EN" or "FR" and put invisible tags where the language is not select. I can do Javascript to change CSS but because I use CSS to hide and show my question-anwser, I wanna know if I can do it with only CSS.
Here a sample of what the template is, wher the info I want and where I want to apply css after.:
<div>
<div>
<div>
<div class="languageCode" id="fr" style="display: none; visibility: hidden;">fr</div>
</div>
</div>
</div>
<div class="MainContent">
<div>
<h1>FAQ</h1>
<label><input type="checkbox" id="language" />Français ?</label>
<ul class="collapse-list">
<li class="fr">
<label class="collapse-btn" for="question-1">
Titre FR1
</label>
<input class="collapse-open" type="radio" id="question-1" name="question" aria-hidden="true" hidden="hidden"/>
<div class="collapse-panel">
<div class="collapse-inner">
<p>
texte
</p>
</div>
</div>
</li>
<li class="en">
<label class="collapse-btn" for="question-2">
Title EN1
</label>
<input class="collapse-open" type="radio" id="question-2" name="question" aria-hidden="true" hidden="hidden"/>
<div class="collapse-panel">
<div class="collapse-inner">
<p>
text
</p>
</div>
</div>
</li>
</ul>
</div>
</div>
Here a small part of the CSS
.collapse-open
{
display: none;
}
.collapse-panel
{
display: none;
margin-left: 10px;
}
.collapse-open:checked ~ .collapse-panel
{
display: block;
}
Here the part that I want to do but I can't say how to make it work
#fr.languageCode ~ .fr{
visibility: hidden;
display: none;
}
#fr.languageCode ~ .en{
visibility: visible;
}
#en.languageCode ~ .fr{
visibility: visible;
}
#en.languageCode ~ .en{
visibility: hidden;
display: none;
}
Like if the ID is #fr you display only french content and if ID is #en you display only english content.
Note: I know the selector in my CSS doesn't work but I can't find what I should use or if it's possible to do what I want without javascript.
You can try using :lang selector css. But, it can be tricky taking into account all cases, xml lang etc. I think the javascript to detect the user's browser's language is simple, so why not just set a global class based on that, and then you can hide / show with css accordingly. You do need to make sure you've got a complete list of possible lang values.
var language = window.navigator.userLanguage || window.navigator.language;
alert(language);
document.getElementById('content').className = language;
div {
visibility: hidden;
}
#content.fr .french {
visibility: visible;
}
#content.en-US .english {
visibility: visible;
}
#content.sp .spanish {
visibility: visible;
}
<div id="content" class="default">
<div class="french">Si votre navigateur préférence lang est francais , vous devriez voir cette
</div>
<div class="english">If your browser lang preference is ENGLISH you should see this
</div>
<div class="spanish">Si su navegador lang preferencia es espanol debería ver esto
</div>
</div>
