I made a calendar where I can click on each day.
When I put my mouse on the last column div, it overflows the screen width.
<div class="menu">EEEEEEE</div>

You can apply transformation on last <td>, to pull tooltip to the left:
td.ui:last-child .ui.simple.dropdown:hover > .menu {
transform: translate(calc(-100% + 16px), 0);
}
Or put it to the right:
td.ui:last-child .ui.simple.dropdown:hover > .menu {
left: auto;
right: 0;
}
updated fiddle
Edit
Before that count all menu items, that overflows viewport:
$('.ui .menu').each(function(){
var $this = $(this);
if ($this.width() + $this.parent().position().left > $(window).width()) {
$this.addClass('transformed');
}
});
And then apply needed css:
.ui.simple.dropdown:hover > .menu.transformed {
left: auto;
right: 0;
}
fiddle
However it doesn't compensate if tooltip is overflowing in both sides. for that You can check twice:
$('.ui .menu').each(function(){
var $this = $(this);
if ($this.width() + $this.parent().position().left > $(window).width()) {
$this.addClass('transformed');
if ($this.parent().position().left - $this.width() < 0) {
$this.addClass('center');
}
}
});
And apply transformation:
.ui.simple.dropdown:hover > .menu.transformed.center {
transform: translate(50%, 0);
}

At the moment i am using hardcoded height point to trigger visible ScrollToTop Button.
i would love to get solution to be triggered when passing viewport height.
const { scrollDirection } = useScrollDirection()
const { scrollPosition } = useScrollPosition()
const [isVisible, setIsVisible] = useState(false)
const toggleVisible = () => {
if (scrollPosition === 0) {
setIsVisible(false)
}
**if (scrollPosition > 800) {
setIsVisible(true)
} else if (scrollPosition <= 799) {
setIsVisible(false)
}**
}
const scrollToTop = () => {
window.scrollTo({
top: 0,
behavior: "smooth",
})
}
window.addEventListener("scroll", toggleVisible)
you can use window.innerHeight
const toggleVisible = () => {
const viewportHeight = window.innerHeight;
if (scrollPosition === 0) {
setIsVisible(false)
}
**if (scrollPosition > viewportHeight) {
setIsVisible(true)
} else if (scrollPosition <= viewportHeight) {
setIsVisible(false)
}**
}
You can do this by using Intersection Observer (IO)
First you create an element that is just below the viewport initially. And whenever this element comes into view, show the button.
This requires one dummy element which you observe, for the demo I set the html element to position: relative for it to work. Maybe you can use a different element structure, based on your html. Important thing is that you have one element you can observe and trigger the element depending on when it comes into view.
let options = {
rootMargin: '0px',
threshold: 0.1 // when at least 10% of the element is visible we show the button
}
const callback = (entries, observer) => {
const btn = document.querySelector('#scroll-top');
entries.forEach(entry => {
if (entry.intersectionRatio > 0.1) {
// if we are past our 0.1 threshold we show the button
btn.classList.add('visible')
} else {
// otherwise we hide the button
btn.classList.remove('visible')
}
});
};
const observer = new IntersectionObserver(callback, options);
const target = document.querySelector('#button-trigger');
observer.observe(target);
.dummy-viewport {
min-height: 400vh;
}
html {
position: relative;
}
#button-trigger {
position: absolute;
top: 100vh;
left: 10px;
height: calc(100% - 100vh);
/* for demo purposes, don't show the element on the finished site*/
width: 2rem;
outline: 1px solid rebeccapurple;
writing-mode: vertical-rl;
text-orientation: mixed;
}
p {
padding: 0;
margin: 0;
}
#scroll-top {
position: fixed;
bottom: 40px;
right: 10px;
opacity: 0;
transition: .5s opacity;
}
#scroll-top.visible {
opacity: 1
}
<div class="dummy-viewport">
<p> Scroll down ↓ </p>
<button id="scroll-top" type="button"> Scroll to top </button>
</div>
<div id="button-trigger">
<p> When I am visible, I show the button </p>
</div>
i have a div with width: 190px and height: 260px, i assign img tag on that div, when i upload an image that shows how the image before, after that i rotate the image but the width and height of the image didnt change like the div, i have used inherit, everything about position and display, but no good at all..
I have figured out an automated way as below:
First, I am getting natural height and width of the image (from onload trigger):
var naturalWidth = event.currentTarget.naturalWidth
var naturalHeight = event.currentTarget.naturalHeight
Then I am computing a transform scale using aspect-ratio and generating transform style as below (pseudo-code):
For 90deg (y-shift):
const scale = naturalWidth > naturalHeight ? naturalHeight / naturalWidth : 1;
const yshift = -100 * scale;
const style = `transform:rotate(90deg) translateY(${yshift}%) scale(${scale}); transform-origin: top left;`
For 270deg (x-shift):
const scale = naturalWidth > naturalHeight ? naturalHeight / naturalWidth : 1;
const xshift = -100 * scale;
const style = `transform:rotate(270deg) translateX(${xshift}%) scale(${scale}); transform-origin: top left;`
Hope this helps.
Inherit will not work.
Because you have to make the set the width of your image as the height of your parent. Then it will get completely resize in the parent element.
image-width = parent-height
Because after applying transform property width and height property will also get rotate in its respect.
Sol 1:
change the width of your image along with the transform property. (If it is variable then you can use the SCSS variables to assign the same values to the image-width and parent height.)
Sol 2:
This is not the perfect solution but will work in many cases. Add scale property to your transform property like this
transform: rotate(90deg) scale(.7);
Adjust the scale values according to you.
Hey,
Please Try this code.
var $=jQuery.noConflict();
$(document).ready(function(){
$('#RotateButton').click(function(){
$('.col').toggleClass("afterRot");
});
});
/* ----- IE Support CSS Script ----- */
var userAgent, ieReg, ie;
userAgent = window.navigator.userAgent;
ieReg = /msie|Trident.*rv[ :]*11\./gi;
ie = ieReg.test(userAgent);
if(ie) {
$(".col").each(function () {
var $container = $(this),
imgUrl = $container.find("img").prop("src");
if (imgUrl) {
$container.css("backgroundImage", 'url(' + imgUrl + ')').addClass("custom-object-fit");
}
});
}
body { padding: 0; margin: 0; }
.col { position: relative; display: block; width:100vh; height: 100vh; }
.afterRot{ transform: rotate(90deg); object-fit: cover; }
.col img { position: absolute; top: 0; left: 0; right: 0; width: 100%; height: 100%; object-fit: cover; }
.custom-object-fit { position: relative; background-size: cover; background-position: center center; }
.custom-object-fit img { opacity: 0; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="mob">
<button type="button" id="RotateButton"> Rotate </button>
<div class="col">
<img class="nor" id="rowImg" src="https://cdn-images-1.medium.com/max/1600/1*tSyuv3ZRCfsSD5aXB7v8DQ.png">
</div>
</div>
I think this is because you are not removing the class already associated with the Image. Try adding this to your button
$(document).ready(function(){
$('#RotateButton').click(function(){
$('#rowImg').removeClass("normalx").addClass("afterRot");
});
});
for a css like
.col {
width:260px;
height:190px:
border: solid 1px #6c757d;
padding: 10px;
}
.nor{
width:250px;
height:150px;
}
.afterRot{
width:inherit;
transform: rotate(90deg);
}
I have a sample here
I am trying to implement correctly scaling and zooming in css way. I created an example with scaled view. When click, the view should be zoomed and then to be able to scroll.
https://jsfiddle.net/opb5tcy8/4/
I have several issues with it:
Can I somehow get rid of the margin-left and margin-top on the .zoomed class? I did not manage to scale it without necessity to shift it with these margins.
When clicked, I can get the click position by clientX. I would like to use it to fluently scroll to the clicked position during zooming. However I can't manage the scroll to be fluent and when removing the margin-left it is kind of jumpy and not nice.
When you zoom in and move the scroll to the center and then zoom out, you can see the zoom is not nice as it first scrolls to the right. Is there a way to prevent it?
When you scroll to corners in Chrome on OSX it tends do navigate back/forward in browser. Is there a way to prevent this behaviour?
UPDATE:
The first part can be solved with transform-origin: 0 0. The other issues stays mostly the same as it is demonstrated.
Hm... I could say it is impossible to satisfy point 2 your condition with current browsers' support. The other are possible, as in this demo:
$(document).ready(function() {
var windowHalfWidth = $("#window").width() / 2;
var scalingFactor = 0.55;
var throtte = false;
$("#slider").click(function(event) {
//Simple event throtte to prevent click spamming breaking stuff up
if (throtte) return false;
throtte = true;
setTimeout(function() {
throtte = false;
}, 1000);
var xSelf = event.pageX - $("#window").offset().left + $("#window").scrollLeft();
if ($(this).hasClass("zoomed")) {
$("#window").animate({
scrollLeft: (xSelf / scalingFactor - windowHalfWidth)
}, 1000, "linear");
} else {
$("#window").animate({
scrollLeft: (xSelf * scalingFactor - windowHalfWidth)
}, 1000, "linear");
}
$("#slider").toggleClass("zoomed");
});
});
body {
background-color: #eee;
margin-top: 10px; /*reduced margin for easier view in SO */
}
#window {
width: 500px;
height: 200px;
margin: 0 auto;
overflow-x: auto;
overflow-y: hidden;
border: 1px solid #999;
position: relative;
background-color: white;
}
#slider {
width: 900px;
height: 600px;
background-color: #fff;
position: absolute;
transition: 1s linear;
top: 0;
left: 0;
transform-origin: 0 0;
}
#slider.zoomed {
transform: scale(0.55);
}
#slider div {

height: 50px;
line-height: 50px;

}
#obj5 {

}

As you can see, the zooming & scrolling is quite laggy, especially when the far right size is zoomed in.
The reason is simple, because jQuery and css both have their own animation loop, and they are not in sync. In order to solve this we'll need to somehow manage to do both scrolling & scaling animations with only one system, either jQuery or CSS.
Problem is: jQuery don't have a scaling feature, and css can't scroll elements. Wonderful.
If your scaling can be done with width/height though, it would be possible, using jquery width&height animate(). But if the #slider consists of many components I guess it can't be done.
So um writing an answer just to say it's impossible is kind of a let down, so I think maybe I can suggest an alternative, using dragging to scroll content (similar to the way Google map work):
var windowHalfWidth, startX, startLeft, minLeft, dragging = false,
zooming = false;
var zoomElement = function(event) {
var xSelf = event.pageX - $("#window").offset().left - parseFloat($("#slider").css("left"));
if ($("#slider").hasClass("zoomed")) {
minLeft = windowHalfWidth * 2 - 900;
var newLeft = Math.min(Math.max((-(xSelf / 0.55 - windowHalfWidth)), minLeft), 0);
$("#slider").css("left", newLeft + "px");
} else {
minLeft = windowHalfWidth * 2 - 900 * 0.55;
var newLeft = Math.min(Math.max((-(xSelf * 0.55 - windowHalfWidth)), minLeft), 0);
$("#slider").css("left", newLeft + "px");
}
$("#slider").toggleClass("zoomed");
}
$(document).ready(function() {
windowHalfWidth = $("#window").width() / 2;
minLeft = windowHalfWidth * 2 - 900 * 0.55;
$("#slider").on({
mousedown: function(event) {
dragging = true;
startX = event.pageX;
startLeft = parseFloat($(this).css("left"));
},
mousemove: function(event) {
if (dragging && !zooming) {
var newLeft = Math.min(Math.max((startLeft + event.pageX - startX), minLeft), 0);
$("#slider").css("left", newLeft + "px");
}
},
mouseup: function(event) {
dragging = false;
if (Math.abs(startX - event.pageX) < 30 && !zooming) {
// Simple event throtte to prevent click spamming
zooming = true;
$("#slider").css("transition", "1s");
setTimeout(function() {
zooming = false;
$("#slider").css("transition", "initial");
}, 1000);
zoomElement(event);
}
},
mouseleave: function() {
dragging = false;
}
});
});

This variation manages to get CSS to do both animation, by sacrificing the scrollbar (which is pretty ugly imo, who needs it?) and use css left instead.
So I hope if in the end you can't find a good solution, at least you have this to consider as fall back version.
I'll address the points individually and then give an example at the end.
When clicked, I can get the click position by clientX. I would like to
use it to fluently scroll to the clicked position during zooming.
In my opinion scroll animations during transitions can be a bit choppy in webkit browsers. Try balancing the animation time of the jQuery effect with the animation time of the css transition.
When you zoom in and move the scroll to the centre and then zoom out, you can see the zoom is not nice as it first scrolls to the right. Is there a way to prevent it?
Bring the scrollLeft property of the div#window back to 0px. Again, tweaking the animation times will make this less jerky.
When you scroll to corners in Chrome on OSX it tends do navigate back/forward in browser. Is there a way to prevent this behaviour?
You could use the mouseover and mouseout events to toggle a overflow:hidden css on the body.
Here's an example change to your code:
var slider = $("#slider").on('click', function(event) {
if (!slider.hasClass('zoomed')) {
// zoom back to left position
$('#window').animate({scrollLeft:'0px'});
}else{
// zoom to click position within slider
$('#window').animate({scrollLeft:event.clientX + 'px'}, 2000);
}
slider.toggleClass("zoomed");
});
/* stop window scrolling when using slider */
slider
.on('mouseover', function () {
$(document.body).css({overflow:'hidden'});
})
.on('mouseout', function () {
$(document.body).css({overflow:'auto'});
});
And an updated fiddle.
I know there are a lot of posts about div layouts but what I'm looking to do doesn't seem to be on here. I am creating div's that contain dynamic text. Therefore each div is of variable length. I want these div's placed alongside each other, 4 across the page. In other words, each div occupies 25% of the width. The number of div's is variable as well so if there are more than 4 div's, then the remaining would start be placed below in the same fashion. Below is a picture of what I am trying to depict, with the gray boxes being the div's I am creating. Any help is appreciated, thank you in advance!
The div's are created in my function addSuggestion(), which is as follows:
HTML:
addSuggestion = function (counter, company_name, contact_name, street_address_1, street_address_2, phone_number, email_address) {
var output = document.getElementById('container');
var div = document.createElement('div');
var company = document.createElement('p');
company.className = "companyClass";
var contact = document.createElement('p');
contact.className = "otherClass";
var address1 = document.createElement('p');
address1.className = "addressClass";
var address2 = document.createElement('p');
address2.className = "addressClass";
var phone = document.createElement('p');
phone.className = "otherClass";
var email = document.createElement('p');
email.className = "otherClass";
if(counter%4 == 0) {
div.className = "farleft";
}
else if(counter%4 == 1) {
div.className = "centerleft";
}
else if(counter%4 == 2) {
div.className = "centerright";
}
else {
div.className = "farright";
}
if(company_name) {
company.textContent = company_name;
div.appendChild(company);
}
else {
company.textContent = "*** COMPANY INFO ***";
div.appendChild(company);
}
if(contact_name) {
contact.textContent = contact_name;
div.appendChild(contact);
}
if(street_address_1) {
address1.textContent = street_address_1;
div.appendChild(address1);
}
if(street_address_2) {
address2.textContent = street_address_2;
div.appendChild(address2);
}
if(phone_number) {
phone.textContent = phone_number;
div.appendChild(phone);
}
if(email_address) {
email.textContent = email_address;
div.appendChild(email);
}
output.appendChild(div);
}
CSS:
#container {
width: 100%;
}
#farleft {
width: 25%;
position: absolute;
float:left;
}
#centerleft {
width: 25%;
position: relative;
float:left;
}
#centerright {
width: 25%;
position: relative;
float:right;
}
#farright {
width: 25%;
position: relative;
float:right;
}
Assigning width: 25% to each div will get your 4 divs on the same row (counting there are no borders and/or margin/padding on the exterior).
float: left will keep them to the left. In order to get your 'new row' to drop down a line, <br clear="both"> would do the trick:
JSFiddle
If its a row of div's you can store them in a containing div "row" that has a variable height.
Sorry of that doesn't make much sense but try this CSS on the row's div.
min-height: 100px; /*whatever you want the minimum height to be*/
height:auto !important; /*An IE fix for older versions */
height:100%;
The above css will ensure your div is never smaller than 100px but can grow based on its content.
The solution is quite simple:
#container>div {
width:25%;
margin:0;
border:0;
float:left;
}
#container>div.farleft {
clear:both;
}

I have a red div with green child, the green one moves when mouse hovers over it's parent. Pretty simple.
HTML:
<div class="big">
<div class="small"></div>
</div>
CSS:
.big {
position: relative;
width: 200px; height: 200px;
margin: 20px auto;
background: red;
}
.big:hover .small {
opacity: 1;
}
.small {
position: absolute;
top: 0; left: 0;
width: 50px; height: 50px;
background: green;
opacity: 0;
}
JavaScript:
$('.big').on('mousemove', function (e) {
var $this = $(this),
small = $this.find('.small'),
offset = $this.offset(),
cursorX = e.pageX - offset.left,
cursorY = e.pageY - offset.top,
smallX = cursorX - small.width() / 2,
smallY = cursorY - small.height() / 2;
$('.small').css({
top: smallY,
left: smallX
});
});
How to make the green box to disappear when it leaves the red one? :hover in css doesn't work because green div is part of the red one (I quess), so cursor never actually leaves it. Only when you move themouse really quickly the green div can't keep up with the cursor and disappers. Perhaps adding some wrapper elements with specific positioning will do the trick? Or something like jQuery stopPropagation()?
Here's my Fiddle
UPDATE: Here's updated code, based on suggestions from user nevermind. I added a transition, it disappears as I wanted it to, but now there's other problem. When cursor is moved outside the red box quickly, the green box stays at the border of it's parent.
I think this is what you want:
http://jsbin.com/obewaz/1/
http://jsbin.com/obewaz/1/edit
Same html/css, few additions in jquery:
$(document).ready(function() {
$('.big').on('mousemove', function (e) {
var $this = $(this),
smalle = $this.find('.small'),
offset = $this.offset(),
position=smalle.position(),
cursorX = e.pageX - offset.left,
cursorY = e.pageY - offset.top,
smallX = cursorX - smalle.width() / 2,
smallY = cursorY - smalle.height() / 2;
$('.small').css({
top: smallY,
left: smallX
});
console.log(position);
if(position.left<0 || position.left>150 || position.top<0 || position.top>150) {
$('.small').css('display','none');
}
else {
$('.small').css('display','block');
}
});
});
Of course, you can change/tweak values in last condition a little to fit your needs. Idea is: track position of small box, and when it is 'outside' of big box - hide it.
instead of mousemove try mouseover
