I'm trying to create a component, or a view if that is better suited for this, that binds to given model's computed properties and changes style attributes accordingly. I'm using Ember App Kit if that affects in anyway how this should be done.
The component would be a a meter that has 2 computed properties to bind to: "limitDeg", "currentValueDeg". Every model instance that will use this component can supply those as model computed properties to the component.
The meter has 3 overlapping divs - ".meter-div" being just background with no bindings, and one of which will be rotated with CSS3 transform by X-degrees to show the current "limitDeg". So adjusting the "transform: rotate(###deg);" is the key here. There is a "indicator-div", that is simple indicator that similarly rotates based on the "currentValueDeg" with CSS3 animation loop.
Below is a basic rough outline of how I've thought of having the component/view:
<div class="my-component-container">
<div class="limit-div"></div>
<div class="meter-div"></div>
<div class="indicator-div"></div>
</div>
...and I would use it like this for example:
{{#each}}
...
{{my-component}}
...
{{/each}}
1) I would like the component to bind to the model so, that when the "limitDeg" computed property changes, the ".limit-div" will be rotated by X-degrees with CSS3 transform: rotate(###degrees);.
2) I would like animate the ".indicator-div" with a CSS3 animation that loops infinitely, binding to the currentValueDeg computedProperty.
Is this something I should even try do this with one component/view, or rather do it this multiple components/views inside one partial?
If you're using handlebars, just wrap your component in tags that specify it as such:
<script type='text/x-handlebars' data-template-name='components/component_name'>
<div class="limit-div"></div>
<div class="meter-div"></div>
<div class="indicator-div"></div>
</script>
Then include it in your view like this:
{{component_name objectToPassIn=this classNames='my-component-container' tagName='div'}}
If you wanted the component to display a model property, you could do something like this inside the component (using the variables in my example above):
<span class='property-wrapper'>
{{objectToPassIn.objectProperty}}
</span>
Edit:
For the sake of clarity, objectToPassIn is the model that is passed to the view that calls the component.

I have a component item that represents a card with the data about the item. Since all the cards have the same structure (price/color/size/photo categories are shown on each card, nothing more and nothing less), I would like to apply a conditional CSS, but I don't know how, since the cards' style differ (slightly) based on:
price (for example, the card is bigger if the price is lower)
if the user has marked it as favorite
whether they are a part of this or that component (the URL can be the same). For example, in a single view there is the first component with a X card's style and the second component with a Y card's style - but the cards have the same data.
I'd really appriciate any suggestion!
<div [className]="'example-class'"></div>
This allows us to add classes based on a condition:
<div [className]="condition ? 'example-class' : 'other-class'"></div>
Or we could build the class name at runtime:
<div [className]="'class' + someValue"></div>
we can easily toggle CSS classes like so:
<div [class.example-class]="condition"></div>
we can assign a variable class name :
<div [ngClass]="seleted-class"></div>
NgClass can also assign multiple static class names all at once:
We can also use ngClass to assign multiple CSS classes based on multiple conditions.
<div
[ngClass]="{
'example-class': condition,
'other-class': !condition
}"
></div>
<div [ngClass]="['example-class', 'other-class']"></div>

You can use NgClass to add conditional classes. For more info, refer the documentation - https://angular.io/api/common/NgClass
Suppose I want to scrape part of a page to reproduce a particular rendering with, at most, a single CSS.
I can copy the full rendering using browser console commands, but that still produces HTML with classes referencing the CSS stack. E.g.,
<h1 class="x">
<span class="y">Here's a header</span>
</h1>
<div class="z">Here's some more text with a different format</div>
Is there a way to either:
Get all styles expanded inline?
Get all referenced styles defined in a single "computed" CSS block?
I am trying to change the background color of a div using ng-repeat. The color I am trying to pull from the object in the loop. Whenever I do this however it sets my style property equal to blank.
Here is the code that I am using:
<div ng-repeat="channel in channelObjects">
<div class="mediumTile" style="background-color:#{{channel.Color}}">
Channel Color: {{channel.color}}
</div>
</div>
This displays my mediumTile object with the correct channel color displayed. By the style is set to nothing once the page loads
This is what the page displays:
<div class="mediumTile" style="">
Channel Color: 123456
</div>
Am I doing something wrong?
You should use ng-style instead of style, using style with interpolation will cause some browsers to strip the values off (invalid style attribute with the presence of {{ etc..) before even angular has a chance to process it. This happens specifically in IE (not sure which browser you tested this).
<div class="mediumTile" ng-style="{'background-color':'#' + channel.color}">
Also mind the casing as well, color.

I have finally figured out how to use the Twitter Bootstrap Tooltips, and I am trying to style it. I have asked similar questions about other plugins, and they all ended up being specific CSS selectors. For jScrollPane, the track's selector was .jspTrack.
Fiddle
My question is, what is the CSS selector for the Twitter Bootstrap tooltips?
The documentation linked in the comments shows you a sample of the markup that's produced when a tooltip is generated:
Markup
The generated markup of a tooltip is rather simple, though it does require a position (by default, set to top by the plugin).
<div class="tooltip">
<div class="tooltip-inner">
Tooltip!
</div>
<div class="tooltip-arrow"></div>
</div>
It should be fairly easy to determine the CSS selector based on this.
There are additional class names attached to .tooltip that you can see if you open your browser's DOM inspector and then hover your form element. The one in your example generates the following .tooltip element:
<div class="tooltip fade right in" style="…">
If you need to select only the tooltip belonging to a specific trigger element, that depends on where exactly the tooltip is placed in the DOM. The documentation says (just above the first section I quoted):
Usage
The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.
So the selector would be .mytrigger + .tooltip where .mytrigger is the form element triggering that tooltip. The DOM position is determined by the container option, otherwise it's the default as stated.
I am using ng-view to render dynamic data on my page. When the page loads, if I use static html I get this (top):
When Angular loads the page the data is there but it's like the element is still empty (bottom).
If I make even the slightest adjustment in Chrome dev tools, the items snap into place but I cannot get them to prefill without using CSS to make them static sizes, which doesn't work because text is different sizes. The elements in question have CSS of inline-block.
As you can see in this screenshot, I have tried two ways of populating the data, both with the same result:
<div class="cd-rating" ng-class="caseData.scoreClass">
<span class="score" ng-bind="caseData.adjustedScore | number:0" ng-cloak>N/A</span>
<span class="verdict">{{caseData.recommendation}}</span>
</div>
Here is the what the HTML looks like in the browser:
<div class="cd-rating medium" ng-class="caseData.scoreClass">
<span class="score ng-binding" ng-bind="caseData.adjustedScore | number:0">349</span>
<span class="verdict ng-binding">review</span>
</div>
If I hard-code that HTML identically, then it renders perfectly. It's only when Angularjs renders it that the elements are collapsed, appearing if there is not content.
I would also like to add that I am using RequireJS and manually bootstrapping the app instead of using the ng-app directive, in case that matters.
Any ideas on how to make the view fill the elements?
EDIT: Here is a video that demonstrates the behavior: http://youtu.be/zTwv-o6mWRM
I am not able to figure out what exactly you mean by the "..data is still there but the element is empty.." - the only issue that I find with the rendering by AngularJS is that the "Review" (button?) is overwritten with the number.
Looking at your code (which, as #Wingman4l7 suggests needs to be posted in the question rather than as a image), I see that you are using bindings to define a class dynamically. Instead, can you use the ng-class directive and see if it resolves the issue?
That is, replace:
<div class="cd-rating {{caseData.scoreClass}}">
with
<div class="cd-rating" ng-class="caseData.scoreClass">
instead and check if the issue gets resolved?
