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 am writing a Single Web App with material ui, that needs to be responsive, but I do not know which is the control where I must allocate the mains component, if it is a grid or a box.
The next image show the main components arrangement in md,lg,xl
The next image show the main components arrangement in sm,xs when width < 960
In the web I found many complex and very difficult to understand layouts, but not find a basic example. Some like "material ui responsive for dummies".
The mobile version, will have a breakpage between the Appbar and Sidenav, both will occupy the full height, and the Map in the second page will fill the screen.
I did it for you with MU Grids and media queries, if you have questions, ask. I am always ready to help. This is codesandbox link. Let me know if it help you.

It display your layout for md lg xl correctly. For xs and sm screens, sidenav & map take full height with a break page between sidenav and appBar
Thanks to both, it solved the main part o what i need.
Also need to implement a change of page.
I forget to mention that the map will be React-Leaflet,
so need to implement a flap button over the map for the mobile version.
The button is for scroll to up, because any finger movement in the map area only will affect the map content.
Do not will have effect in the scroll.
Another thing to implement is the break page concept:
The behaviour of the break page is like when you see a pdf in presentation mode and press
the keyboard button Repag - Avpag, it change all the content and never see the half top and the half down.

I'm working on some sort of 'continuous' animation. Say a div translates from its current location 200px to the right. There's an option to change the distance of translation. While its animating, the user changes from 200px to 400px. The div should still move smoothly until it reaches its final point which is 400px from its previous location. I have done the basic moving animation, however I can't figure out how to make it continues without jumping when the distance changes.
Here's the codesandbox that I'm working on which best illustrates my point above and what I'm struggling with. Any ideas or help would be greatly appreciated. Thanks :))
Edit: Steps to reproduce the jumping problem:
Open the sandbox
Click the 'Toggle' button
Click the 'Add distance' button
While the red div animates, click 'Add distance' button again
And you should see the div jumping
There is probably a way to fix your code so that it works as you want, though I would suggest going in another direction. There are several animation libraries in React that can help you solve this problem. The resulting code is also going to be more portable.
For your specific need, I would suggest using a library called react-move. It is part of the react-tools which provides other cool libraries. I created a CodeSandbox with my take on your problem using react-move.
I only took the transform line for your code, since I wanted to focus on how you could integrate the library into your example.
To create the animation, I imported a component from react-move called Animate. It's the main component of the library. You use this component to wrap a function using the function as child pattern. This function will receive a state object with information regarding the animated element. It also consumes a start, update, enter, and leave function, that represents the state for those actions.
Inside you function as child function is where you define the animation. In our case, we want to translate the Box along its x axis, using the x value provided on the state object.
OBS: On my example the Box returns to the start (x === 0) when its offset value is bigger than the window's width.
I hope it helps.
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.
I've wasted too much time on this and am begging, begging, I tell you, the stackoverflow community for help!
I'm a new jqGrid user, and have my grid working as I want it to, but at the moment, cannot get a row to highlight in IE 7 as the mouse is hovered over it. Our shop is currently running IE7, so changing browsers/versions is not a possibility. Hover works great in Firefox, does not work in IE7.
I have googled endlessly for "jqgrid ie7 hover", "jquery ie7 hover", and any iteration of "ie7" and "hover", and "css" and all that.
I have tried so many variations of DOCTYPE declarations it ain't funny. I've tried reverse engineering the http://www.trirand.com/blog/jqgrid/jqgrid.html demo pages until my fingers are aching. Yes, the hover works on the demo pages. No it ain't working on my own page. I have tried manually passing in the ui hover CSS classes directly with different attributes and the !important flag just to see if I get anything. Nothing.
Now here is what does happen when I hover over a jqGrid row with IE7: The bottom and right borders of the table cells will change color, but the background color does not. So, I know the hover highlighting is working for the cell borders, but not for the cells or row itself.
As a diagnostic aid, I slapped in a javascript alert() to bang when I hovered over the table. It works at the table level, but does not ever fire if I set it to fire if I hover over a row or cell. I used the IE Developer Toolbar DOM parser to verify I'm calling it right. I'm wondering if jqGrid takes over that functionality, though.
Anyhow, folks, the short version is: Why can't I get row highlighting to work in IE7?
Help me Obi Wan Kenobi, you're my only hope!
I'll answer my own question. The problem was a conflict with a separate .css file. My page uses the 960 Grid System for layout control. One of the items used as part of the grid system is a "reset.css" which was conflicting with the jqGrid hover display in my app. I commented out the call to reset.css and the problem went away. Fwiw, I did not see any other adverse affects to the grid system by leaving out reset.css.
