In the following site https://www.ilmiomedicolegale.it/ I have inserted carousels with autoplay on the mobile side (unfortunately using Elementor).
Autoplay starts as soon as you arrive on the site, my intention is to make them start as soon as they are visible on the screen or at least as soon as the section is visible.
In order to reach the certain sections through the menu items and view the beginning of the various slides in the correct order.
Do you know how I can intervene? I have knowledge of JavaScript but I really don't know where to put my hand for the solution..thanks in advance!
PS. I have seen that it uses Swiper Js

We want to put multiple pictures on a carousel with multiple sizes using swiper and the centered slide. Unfortunately, each picture stays on one slide by slide.
We tried to use flex shrink, changed the space between to get multiple pictures on one slide and many parameters trying to get things done. But when we come on the summary of each articles which includes some pictures, some bugs still there at the onClick.
We just want to know if it's possible to reach thing out.
Thank you
I am a beginner in coding and as a challenge, I decided to make my own portfolio website on react.js + tailwind without the use of extra plugins. (I know, I know, as I figured out later, it was not my best idea)
The main complexity was around making a background behind the slider to look similar to the central slide, and to make a smooth transition.
After hosting the website, I found a glitch that is only visible on mobile browsers. Basically, every time when I change a slide, in the moment of changing State, it flicks the next slide in the array of slides for a millisecond.
I was able to see the same issue in dev tools but does not work every time.
100% visible only on mobile browsers
Small clarification: the slider is functioning by rotating elements within the array by the method Splice. So elements [1],[2], and [3] are always visible on the desktop version while elements [0] and [4] exist but have zero opacity (it is made for the sake of the smooth background transitioning).
The glitch itself: On clicking 'left' the image from element [1] is becoming the central image [2] and it flicks somehow the image from [0] for a millisecond. The same behavior is related to the right image from element[3] and background images. Though, it does not affect the left visible slide [1], because its predecessor is only becoming visible after State change.
My best assumption is that the issue is related to the component "Portfolio" 126 line in the code, but I can not find any other solutions which work.
const onChangeSlide = (direction) => {
if (direction === "left") {
setTimeout(() => {
slides.splice(0, 0, slides.splice(length-1, 1)[0]);
setSlider((prev) => ({...prev , ...slides}));
},700);

I will appreciate any help. Thank you in advance.
Regarding the first issue I checked all images, and their order, and removed StrictMode. No luck for me. I can not grasp how the slider shows the element which supposed to be visible only on the next click. And it is not visible on the fast internet desktop version. As stated above, my best guess is that it is related to the way how I change State.
UPDATE: It looks like after scrolling through all carousels BOTH left and right the flick is disappearing.
So, I assume, it somehow connected with the browser's cache, but I don't understand why it needs to be scrolled in both directions first before the issues disappear. All files are supposed to be preloaded after the first scroll in either direction, not both.
Please help🙌
I'm about to try to create a walkthrough for a web app created using React. I'm trying to think of the best way to do it, and have been thinking of using things like Material UI's modal component. I'm thinking I should also include some kind of arrow component that points the user to whichever element (button, link, etc) on my page I want them to click next. Also I will want to create a backdrop to fade the screen except for whichever element I want the users attention to be drawn to.
I feel like this must have been done many times before, but I can't find anything from searching. Obviously whenever I Google "react walkthrough/guide/intro" I just get suggestions for teaching basic React.
(NB: I'm not looking to do one of those intro sliders, as I want to provide a more detailed step-by-step)
The keyword your need to search for is 'tour'. Searching on google for 'react tour', I found 2 libraries for you:
React Joyride: https://github.com/gilbarbara/react-joyride | Live Demo
reactour: https://github.com/elrumordelaluz/reactour | Live Demo
Both seem to have similar features:
Instruction modal that explains about an element on the page.
The modal is positioned next to the highlighted element.
The window will scroll down to the highlighted element if it's outside of the viewport.
The element is highlighted to bring more attention while the rest of the page is in the backdrop.
There are steppers on the modal to indicate which step you're on.
I have a chat page in a ionic project and like most chat apps I want to start the list of messages at the bottom of the page.
As far as I know with the help of google in the web world it is not possible to generate a list of items in a reversed order on the screen like in native apps.
The most common work around for this is scroll the page to the bottom on page load. I tried this and in most cases there are performance issues, scroll delays, list not responding for a few seconds etc. so not the desired solution.
No I came up with a different approach, with css I flipped the list of items so that the list is upside down. I also flipped the items in the list so that they are flipped back and are not upside down anymore. Now I have the result I want, I have a list with items with item 1 at the bottom without the need to scroll to the bottom.
.listUpsideDown {
-webkit-transform:rotateX(180deg);
transform:rotateX(180deg);
}
.messageUpsideDown {
-webkit-transform:rotateX(180deg);
transform:rotateX(180deg);
}
There is only one downside, because I flip the list the scroll direction is also reversed. So now I'm looking for a way to reverse the scroll input direction.
I hope someone can help me with this.
I have a working fiddle with my current situation where I need to reverse the mouse scroll input direction jsfiddle example .
Instead of doing other workarounds, stick to scrolling to bottom. As you are using ionic, use $ionicScrollDelegate service, Just call $ionicScrollDelegate.scrollBottom(); from your controller when you want to scroll to bottom.
Plus if you want to put animation, while it is going to bottom use $ionicScrollDelegate.scrollBottom([true])
I'm currently developing a mobile web application with AngularJS, ngAnimate, Angular-Material and UI-Router. I'm following Google Material Design specifications for the UI/UX part.
I'd like to animate a state change 'the Angular way' and especially this 'Parent to child' animation
I've no idea on how to achieve this 'lift & expand' animation.
Thanks for your help !
You have to do it yourself, I guess.
Angular-material is not a magic wand that replicates the animation guidelines of Material Design. Material Design guidelines are simply guidelines, and are loose enough to be hacked — or strictly followed, in the case of Google's Android apps (in-house or not).
My feeling is the angular material team is already pushing like maniacs to bring this awesome tool to 1.0, and will take advantage of the new routing system in Angular 2 to provide some animations like the one you wish to attain out of the box.
But it's the bleeding edge of the bleeding edge, at least for the time being.
Good news seem to be that routes will have their own viewports and sibling viewports.
AngularJS somewhat starts to embrace Polymer's web components concept.
Scroll to "Show me the magic!" on this page, and check these demos. Polymer's ecosystem provides a lot of already-made components to build your app with. It's quite large, and makes you wonder why Polymer doesn't get the same momentum as AngularJS. But I digress...
Option 1
create a custom-made function that gets triggered on a list element being clicked/tapped, to place in your controller (or directive).
Once the user clicks/taps the list element, it triggers the function (console test).
The function should :
retrieve the id of the clicked/tapped item (pass it to the function)
animate : here you have several choices, but here's one : use a ui-router absolute named view (#view_name), and wrap it in a div container with overflow:hidden, that has inital dimensions corresponding to the dimensions of a list item.
Detect the x-y position of the list element that has been clicked (an example, assuming you use AngularJS with jQuery), and you pass it to the "item detail" route (see above), so the rectangle grows with origins corresponding exactly to where the UI is a the moment of the click/tap. The animation shown in the video seems pretty complex: the "item detail page" grows slower on the bottom and faster on the top, when the bottom item is clicked.
Why an absolute named view? Because it will allow, with z-indexing, for the list to stay underneath the "item detail" view, so when the user closes/leaves it, you can roll back your animation, and the rectangle will shrink back to exactly the dimensions and position of the list item. Finally, you transition the opacity:0 and leave the route.
Option 2
Here's a rough mockup of a technique stretching/scrolling an ion-item. It would require to detect the y position of the item, and use ionicScrollDelegate to scroll to it. Also, you would freeze the main scroll so the user get "stucked", until he closes the "detail view", which then releases the scroll.
$scope.toggleStretchedMode = function(itemID) {
$scope.stretched = $scope.stretched === false ? true: false;
if(!$scope.stretched){
$('ion-item').removeClass('stretched');
$ionicScrollDelegate.freezeAllScrolls(false);
}
else
{
$location.hash(itemID);
$ionicScrollDelegate.$getByHandle('mainScroll').anchorScroll(true);
$ionicScrollDelegate.freezeAllScrolls(true);
$('#'+itemID).addClass('stretched');
};
}
A very basic JSFiddle, which needs to be refined (clicked item should scroll to the middle of the screen, then expand).
Note that the JSFiddle only blocks the mousewheel scroll. If seems to block the first swipe, but then the ng-click releases it, so as it is it's far from perfect. You should not only block the list scrolling, but the up and down swipe events.
Also it initalizes badly, only works the second time. But the concept could be something like this.
