I was wondering how I could set up css pseudo classes, specifically hover so when I hover over an element, like a div with an id, the properties of a different div with an id get changed?
so normally it would be this:
#3dstack:hover {
listed properties
}
I'm not sure what the change would be to have it hover on div with the id 3dstack and have it change another div.
I do not think that is possible unless the element you want to change the properties of is a descendent or a sibling of the hovered element, in which case you can do:
#myElement:hover #myElementDescendent {
background-color: blue;
}
/*or*/
#myElement:hover + #myElementSibling {
background-color: blue;
}
Of course you can always use jquery to do this:
$("#anelement").hover(
function() {
$("otherelement").css("background-color", "blue");
});
See the differences here
This is not possible with CSS alone. You'll have to use a JavaScript event handler. For example, with jQuery's hover:
$('#3dstack').hover(function() {
$('#otherID').toggleClass('properties');
});

Visually you can do this using LESS, but under the hood it's actually using JavaScript.

i try to hide several polymer elements on a certain element condition. I'm aware that there are several possibilities. In my opinon the easiest way to do this is to introduce a new CSS class
.invisible {
display: none;
}
and add it to the class list of the polymer elements
this.$.icon.classList.add('invisible');
this.$.text.classList.add('invisible');
this.$.button.classList.add('invisible');
But this has no effect on the elements. The elements are still visible. A look into the elment inspector shows, that the class was added:
class="style-scope parent-elem invisible"
Where parent-elem is the name of the parent element.
Can anyone explain me why the element will not be hidden?
Thank you

you can easly manipulate on your elements with parent property. Try in your element properties add property
properties: {
...
elementsVisible: {
type: Boolean,
value: true
}
...
}
then in your method manipulate this property and in html component set
<element hidden="[[!elementsVisible]]" ></element>
ps. if this wont work you can add in parent css
[hidden] {
display: none;
}
sometimes polymer elements need special mixins to customize their css, but hidden usually works :)
How do I achieve something like this:
*:hover{
background-color:lightblue;
}
I am trying to change background color of any element on the page when hovering on the element. Not sure why it doesnt work.
It works fine http://jsfiddle.net/mendesjuan/9pta8vbz/
The problem is that it's highlighting the entire body since the mouse is over the body, so you don't see highlighting on children any differently.
The following example should clarify it http://jsfiddle.net/mendesjuan/9pta8vbz/1/ It will highlight items inside the body
CSS
body *:hover{
background-color:lightblue;
}
HTML
<p>1 <span>inside</span></p><p>2</p><p>3</p>
It will highlight the paragraphs, but the span will behave the same way since the paragraph will also be highlighted
What you are doing cannot be done with CSS alone, you can use JS to add a CSS class to the element that the mouse is over http://jsfiddle.net/mendesjuan/9pta8vbz/2/
CSS
.highlight {
background-color:lightblue;
}
JavaScript
// This is a simplified version that doesn't take care of edge cases
// known bugs: should use addEventListener, should not wipe out existing `className`,
// e.target is not 100% cross browser, but those are other topics
document.onmouseover = function(e) {
e.target.className = 'highlight';
}
document.onmouseout = function(e) {
e.target.className = '';
}
In Chrome and Firefox, the following doesn't have the desired effect:
<style>
#hoverOnMe { background-color:orange; }
.open:hover { background-color:lightblue; }
</style>
<div id='hoverOnMe' class='open'>HELLO</div>
The :hover doesn't work. The background remains orange on hovering.
However, each of the other three possible combinations (listing by id twice, listing by class twice, and listing by class followed by id) works.
Of course my actual project is a little more complicated than this example; I'd like to add an "open" class to every hoverable element.
What's going on here? What's the simplest workaround?
I'd like to add an "open" class to every hoverable element.
Well if this is the case and you expect the same behaviour for all elements,
then you could just use !important:
.open:hover {
background-color:lightblue!important;
}
In my page,I use tooltip which class name is .tooltipcell to the grid cell,and also use tooltip which class name is .tooltipbtn to the button.Now I want to change the background color of the tooltip in grid,but I do not want to affect the background color of the button tooltip.How to do that?I use to codes below,it affects the two tooltip.
method1:both effect
.k-widget.k-tooltip{
background-color:red; //set the desired color
}
method2:both effect
div .k-widget.k-tooltip{
background-color:red; //set the desired color
}
JS
show: function (e) {
e.sender.popup.element.addClass('red-tooltip');
},
and CSS
.red-tooltip {
background-color: #f00 !important;
}
You can do this:
.tooltipcell{background-color:green;}
.tooltipbtn{background-color:green;}
Just incase your div .k-widget.k-tooltip might overwrite the style you may have to target it deeper like this:
div .k-widget.tooltipcell{background-color:green;}
div .k-widget.tooltipbtn{background-color:green;}
The is an amendment to MarioD Answer.
I didn't test it but given that it works, a better practice would be to concatenate these classes. It saves size in the css and improves loading time. Do this:
div .k-widget.tooltipcell, div .k-widget.tooltipbtn {
background-color:green;
}
I had the same problem where I was using kendo tooltip. I wanted to change the CSS of the tooltips only in one place leaving the rest of the tooltips intact.
Using css the normal way to do this would be to use target .widget and .k-tooltip CSS classes.
Although this would change all the tooltips within a page.
So, since I wanted to change only one tooltip (same problem as this post) I had to do a JS approach.
So, I had to use the show function of kendo's tooltip.
Example:
$('.target')..kendoTooltip({
position: 'bottom',
showAfter: 1000,
content: 'test',
function(e) {
e.sender.popup.element.addClass('customClass');
}
}).data('kendoTooltip');
I will try to post here a jsfiddle in few moments.

I have a set of div whose visibility is set to either hidden or visible. Based on this css visibility property i need to add the css property on those div, like
<div class="div-class" style="color:#ff0000; margin: 0px 10px; visibility:hidden;">
[Block of Code]
</div>
Now i need to define the following in style.css file.
.div-class:visible {top:10px;left:50px;}
.div-class:hidden {top:0px;left:0px;}
Is this possible???
yes with css attributre selectors you can do it
try the below css:
.div-class[style*="visible"] {
color: green;
}
.div-class[style*="hidden"] {
color: red;
}
What you are trying to do is not "really" possible.
I mean it's ill thought by design in the first place.
Even Vamsikrishna's solution might not work as expected.
If you set the overflow property to hidden via javascript or inline styles, the .div-class[style*="hidden"] rule will apply since the style attribute will contain the hidden string.
Moreover , setting inline styles on html elements is bad practice itself in most cases.
I suggest you try and learn css principles a little more.
I'd do the following:
HTML
<div class="div-class div-hidden">
[Block of Code]
</div>
CSS
.div-class {color:#ff0000; margin: 0px 10px; top:10px;left:50px;}
.div-hidden {visibility:hidden;}
.div-class.div-hidden {top:0px;left:0px;}
Then you can use javascript to toggle the "div-hidden" class.
You can do something using attrchange - a jQuery plugin ,
like this:
Add "attrchange" script into HTML page like
In Javascrip catch event
var email_ver_input = $("input#email_ver_input.verifyInput");
email_ver_input.attrchange({
trackValues: true,
callback: function (event) {
if (email_ver_input.is(":visible")){
$("#inputcode_wrap").show();
}
}
});
