I'm building an app with flip cards with three buttons each. I need to show the text in the button clicked on the back of the card. How can I do this in Svelte?
<section class="front-side">
<button aria-label="Pizza" on:click={flip}>PIZZA</button>
<button aria-label="Donuts" on:click={flip}>DONUTS</button>
<button aria-label="Hot Dogs" on:click={flip}>HOT DOGS</button>
</section>
<section class="back-side">
Great! We like {data} too.
</section>
This can be solved in a number of ways but the easiest is CSS and the class directive. Whenever one of your options is clicked just toggle a flipped variable and bind it to a class of the same name on a div that wraps the front and back of the card.
If you want to inform the parent of the flip component about the option selected for each card you can dispatch the clicked card's data and handle it how you see fit.
Here's a simplified example in the REPL with CSS pretty much scraped from the W3 Schools tutorial on flip cards the only difference would be instead of hover being the trigger the flipped class has the transform inside it.

I am new to css and flex. Below is the working url in stackblitz.
https://stackblitz.com/edit/angular-ivy-bh8m8u?file=src/app/app.component.html
I have a left panel and main panel and a click button on the top of the page.
Requirement 1 On the click of the button i want to open the side panel. For some reason the side panel is not opening.
Requirement 2. I want to update the css to use flex if is possible because i am new to flex also
Please help.
Your sidePanelOpen variable isn't updating, and your sidePanel element is translated -150%, so it's off to the left of the screen
Never done any Angular but using the power of logic I've figured out half your answer. Now all you need to do is read a quick CSS tutorial
You originally were just setting this variable true. Using ! you can negate the sidePanelOpen value and get a toggle action going
.ts
openSideBar() {
this.sidePanelOpen = !this.sidePanelOpen;
console.log(this.sidePanelOpen);
}
Here you had the toggled class being set on the wrong element.
.html
<div [ngClass]="{'toggled' : sidePanelOpen}" class="sidebar" id="sidePanel">
<div>
<span id='close'>x</span>
<h4>Bangalore </h4>
</div>
</div>
Lastly, the toggled class won't do anything unless you have some css to hide your side panel
.css
#sidePanel.toggled {
display: none;
}
I am trying add a button (to open the side panel) , but for some reason it shows up on the top left of the page. I want it to appear on the middle (right side) so when the user clicks on it the panel displays. I also want the current content on the page to zoom in when the side panel opens so the user is able to see both panel and the current content.
descripition of what you want talk
<div>
<button mat-button (click)="left.open()">Field Definitions</button>
</div>
what is the correct CSS to?
I believe you're looking for this, it's an example provided in the Angular Material Documentation.
There are several ways to position the sidenav toggle button, you can either use CSS Flexbox or just add float: right property to the button. I would choose the first method combined with the use of mat-toolbar.
I want to make CSS animation, based on this example. It fits me perfectly, however there are 2 things that I couldn't make. First - I want customize inner side of greeting card with two jpg files (inner-left, inner-right). Second - I want card open on click, and not click and hold.
I have tried to make it myself with trials and errors but was unsuccessful. If I include third file (inner-left) and make backface-visibility: hidden it's still not giving me required outcome. I have also tried to edit this example but still couldn't make it. For css animation savvys it should be simple, I guess, so please can anyone help me out.
This is html that I am using,
<section class="container">
<div id="card">
<figure class="front"><img src="img_card/1.jpg"></figure>
<figure class="inner-left"><img src="img_card/1-2.jpg"></figure>
<figure class="inner-right"><img src="img_card/1-3.jpg"></figure>
</div>
</section>
and the css part is in jsfiddle link.
It is possible to do this without JavaScript by using a hidden checkbox, a label and the :checked and sibling (+) selectors.
Take a look at this fiddle which also has the inner-left and inner-right images.
I had a quick look at something like this before and I think that might need to be achieved with either a javascript event that adds in a class on click to move your card to its open state.

The above link goes to an example that shows a single card flipping but it should be close to the concept you are looking for
I hope that helps
I am using angular and I need to add an animation that will increase the size of the image.
<div class="card">
<div class="item images-parent">
<img src="img/carryout-icon.jpg" class="left-image"></img>
<img src="img/or.jpg" class="center-image"></img>
<img src="img/delivery-icon.jpg" class="right-image"></img>
</div>
</div>
demo:
http://play.ionic.io/app/933b5926b6da
I want to add same animation/transition to first and third image when the user clicks on it and should be removed when user clicks on the other one i.e if I click on first image, it increases in size, then if I click on the other one, first one goes back to normal and second one has that animation.
Also, I have tried doing it but I am just not able to get ngAnimate, I am not a CSS person either. Also, Any resources to help someone like me would be appreciated.
I see events such as ngView , ng if e.t.c But I do not really want these animations on such events. Only when user clicks on the image. Am I even supposed to use ngAnimate here?
I do not know which particular image you intend to increase it's size on click, but here's one way to go about it.
You can create a css class that increases the image, and you toggle on or off with NgClass, A tutorial Scotch.io
That is to make sure it changes class, but if you want to toggle on/off the class when you click CodePen snippet below
$scope.isActive = false;
$scope.activeButton = function() {
$scope.isActive = !$scope.isActive;
}
I am not a clean CSS coder, so this may be the crux of my problem... but...I've cobbled together an interactive map from this tutorial: http://www.noobcube.com/tutorials/html-css/css-image-maps-a-beginners-guide-/.
My solution: http://www.paideiaschool.org/testing/barb_map.htm
I think I have the initial "rollovers" of the map working-- (I've only coded the first two buildings in the upper left of the map) and am happy with that.
My problem is I want the legend of the map to do the same things as the rollovers of the map. I've come up with a clumsy solution that works (labeled '1509'), but not well in all browsers, and that tells me I have gone wrong somewhere.
I'm trying to avoid javascript as well.
What is the main problem?
Here's an updated jsFiddle for part one
Here's the basics:
<div id="city-map">
<div class="pop-up">...</div>
<div class="pop-up">...</div>
...
</div>
We use an image map with anchor tags as "hot spots". We use CSS to absolutely position these "hot spots" in the proper location and we do the basic background image sprite "trick", the same you did in your original code.
However, I updated your sprite image to have two "hover" images. When making an image hover map with none-square image spots (like buildings overlapping each-other), a single hover state runs into problems with a "neighbor" icon showing up in the hot spot slice. This is due to due HTML blocks being square and not being able to draw odd shapes. We solve this by having extra images states so you can make the neighbors still look un-highlighted.
Pop-up box
<div class="pop-up">
<h1 class="title">Mac</h1>
<div class="content">Some Content</div>
</div>
All the pop-up boxes have this HTML format. I position: absolute; them off to the side with the standard left:-999em; trick. I crafted the CSS to give them a standard pop-up location with a slight space between the hot-spot box and the pop-up box. This helps ensure your mouse will "hover out" of the hot-spot when reaching for a new hot-spot. Otherwise, you'll hover over the pop-up box and it won't go away until you over off both.
<div id="city-map-legend">
<div id="glamour-photo">
<img src="..." id="mac-img" />
<img src="..." id="admin-img"/>
...
</div>
<div id="cml-list">
<h2>Around Campus</h2>
<ul>
<li><a id="mac-list" href="#">Mac</a></li>
...
</ul>
</div>
</div>
For the "map legend", I have a group of "glamour images" and a list of links. Pretty standard stuff. The key is how they're all tied together with their ID's. JavaScript will use this to swap images and CSS states as we tie the three elements (map, glamour image, and list of links) together.
ID's in the map are the straight up ID name like "mac". ID's in the glamour images are "[id]-img" (ie. "mac-img"). And ID's in the list are "[id]-list" (ie. "mac-list").
<script type="text/javascript" src="*"></script>
* = http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js
I recommend using jQuery to help do easy JavaScript-ing and loading it from Google API for easy Content Delivery Network benefits.
All that's really left is the JavaScript event.
$(document).ready(function() {
// highlight map when legend link is hovered
$('#cml-list a').hover(
// hover over
function(){
// get id code
var id = $(this).attr('id');
// tokenize string to get main id code
var tokens = id.split('-');
id = '#' + tokens[0];
// add active class to map id
$(id).addClass('active');
},
// hover out
function(){
// clear all .active classes from map
$('#city-map a').removeClass('active');
}
);
});
What happens above is we tell JavaScript to trigger anytime someone hovers a list link. There are two events when hovering, in and out.
When someone hovers into a link, we get the base ID value from it and all we do is apply a CSS class "active" to the map "hot spot".
".active" class will basically "turn on" the map item as if it was hovered (if you notice in the CSS, all the :hover selector styles are also shared with a '.active' class).
When we hover out, we simply tell jQuery to remove all 'active' classes. All that's left to do is swap also write some code that does the same thing for the "glamour" images. Simply turning them on (display:block) or off (display:none). The one catch is that there should probably be a default image that we always turn back on if nothing else is selected unless we just want the previously activated glamour image to stay active, that works too.
I've not gotten to that bit of code yet. I'll see I can update it later and maybe leave a little bit for you to play around with.
update
I developed it mostly in Chrome and a little Firefox. I just checked
it in IE7/8/9 and it seemed to work fine.
I updated the jsFiddle to include glamour image swapping. I also had a small CSS bug where I placed the float in the wrong spot. So, work off the latest one.
NOTE I did not do the CSS for all the locations. I did several with some examples, but left the rest for you. =)
Btw, I updated your map image and uploaded it on imgur.com => http://i.imgur.com/n7spM.png
