I want my divs to change colour upon hovering over them, but the code is not executing even when I'm hovering. I'm not completely sure why, but I think there could possibly be an issue with the fact that I'm using a z-index on the class I want to hover over.
Html with script:
$(".eventContents").hover(
function() {
$(".eventContents").css("background-color", "yellow");
})
//making events square
var cw = $('.eventContain').width();
$('.eventContain').css({
'height': cw + 'px'
});
.eventContain {
position: relative;
margin-bottom: 10px;
z-index: -1;
background-size: cover;
}
.eventContents {
color: white;
padding: 5px;
position: absolute;
bottom: 0;
left: 0;
}
.eventContents h2 {
font-size: 2em;
font-family: 'Montserrat', sans-serif;
}
.eventContents p {
font-size: 1em;
font-family: 'Roboto', sans-serif;

Here is the fiddle, the issue is more prominent here:

It seems to work for me, if I understood correctly, but here's a way to hover both on and off and use this instead of .eventContents twice more..
$('.eventContents').hover(
function() {
$(this).css('background-color', 'yellow');
},
function() {
$(this).css('background-color', 'red');
}
);

The elements are being correctly hovered and the code is getting executed I've tested it, the problem is maybe that your elements are position:absolute; and they're all in top of each other, also they don't have a defined height and it's necessary because we are talking about div elements not img, maybe you'd want to check out your code a little bit better.
You'll want to put a top:0px; to your .eventContents because it's hidden on top (at least for this example)
One last thing, if you want to refer to the actual hovered element, you should use $(this) instead of the class name because it'll execute the code for all the elements with the class and not only the hovered one.
The negative z-index is the reason why the hover is not working, to fix it, make sure that the z-index of the element you want to hover over is positive. To avoid affecting the top nav bar, move the nav bar to the bottom of the html code file allowing it to naturally appear on top of everything else, avoiding the need to use a negative z-index on eventContain.

I have a set of div elements inside a container, .div-to-hide is displayed by default whilst .div-to-show is hidden.
When I click in .set, .div-to-hide should hide and .div-to-show should be visible. Next click should return the previous clicked element to its default state.
I need to display to buttons on click inside on .div-to-show.
<div class="container">
<div class="set">
<div class="div-to-hide">Some text</div>
<div class="div-to-show"></div>
</div>
<div class="set">
<div class="div-to-hide">Some text</div>
<div class="div-to-show"></div>
</div>
<div class="set">
<div class="div-to-hide">Some text</div>
<div class="div-to-show"></div>
</div>
</div>
So far I have this:
let lastClicked;
$('.container').on('click', function(e) {
if (this == lastClicked) {
lastClicked = '';
$('.div-to-hide').show();
$(this).children('.div-to-hide').hide();
} else {
lastClicked = this;
$('.div-to-hide').hide();
$(this).children('.div-to-hide').show();
$(this).children('.div-to-show').hide();
}
});
Can't get it to work properly tho.. I don't know what I am missing...
Any help is deeply appreciated!
UPDATE: got it working! Thanks everyone!
First, you are not using delegation (second parameter on the $.on() function) to define the .set element as your this inside the function.
If I understood correctly, you want to show the elements on the last one clicked and hide the rest. You don't really need to know which one you last clicked to do that
$('.container').on('click', '.set', function (e) {
// Now "this" is the clicked .set element
var $this = $(this);
// We'll get the children of .set we want to manipulate
var $div_to_hide = $this.find(".div-to-hide");
var $div_to_show = $this.find(".div-to-show");
// If it's already visible, there's no need to do anything
if ($div_to_show.is(":visible")) {
$div_to_hide.show();
$div_to_show.hide();
}
// Now we get the other .sets
var $other_sets = $this.siblings(".set");
// This second way works for more complex hierarchies. Uncomment if you need it
// var $other_sets = $this.closest(".container").find(".set").not(this);
// We reset ALL af them
$other_sets.find(".div-to-show").hide();
$other_sets.find(".div-to-hide").show();
});
Consider using class toggling instead.
$('.set').on('click', function(e) {
$('.set').removeClass('hidden-child');
$(this).addClass('hidden-child');
});
css:
.hidden-child .div-to-hide, .div-to-show {
display: none;
}
.hidden-child .div-to-show, .div-to-hide {
display: block;
}
This will make your code easier to reason about, and lets css control the display (style) rules.
Edit: changed class name for clarity; expanded explanation; corrected answer to conform to question
Try to make use of siblings() jQuery to hide and show other divs and toggle() jQuery to show and hide itself and also you will need to set click() event on .set, not in .container
$(document).on('click', '.set', function(e) {
$(this).find('.hide').toggle();
$(this).find('.show').toggle();
$(this).siblings('.set').find('.hide').show();
$(this).siblings('.set').find('.show').hide();
});
.show {
display: none;
}
.set div {
padding: 10px;
font: 13px Verdana;
font-weight: bold;
background: red;
color: #ffffff;
margin-bottom: 10px;
cursor: pointer;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="set">
<div class="hide">1 Hide</div>
<div class="show">1 Show</div>
</div>
<div class="set">
<div class="hide">2 Hide</div>
<div class="show">2 Show</div>
</div>
<div class="set">

i'm working on a fullscreen clickable slideshow with overlaying. While the starting color of this menu is white, i'm wondering if it is possible to maximize legibility by switching to black on lighter images.
The order of the slideshow is permanent, so there is nu guesswork involved with which image should show a white or black version. Is there a simple solution for this problem?
I'm aware that there are countless questions around this topic, but it seems that in all these cases text is nested in. Or the suggested .js scripts are way to elaborate for (what seems) such a simple problem.
Thanks in advance.
HTML
<div class="fullscreenslideshow">
<div style="background-image:url(image1)" class="dark"></div>
<div style="background-image:url(image2)" class="light"></div>
<div style="background-image:url(image3)" class="light"></div>
<div style="background-image:url(image4)" class"dark"></div>
</div>
JS
$('.dark').click(function(){
jQuery('h2').toggleClass('textlight');
});
$('.light').click(function(){
jQuery('h2').toggleClass('textdark');
});
CSS
.textlight {
color:#FFF;
}
.textdark {
color:#000;
}
You could use white text with mix-blend-mode: difference; (see here for more examples)
div {
background: linear-gradient(to right, rgba(0,0,0,1) 0%,rgba(0,0,0,1) 25%,rgba(255,255,255,1) 44%,rgba(255,255,255,1) 60%,rgba(255,0,0,1) 79%,rgba(255,0,0,1) 100%);
}
h2 {
padding: 24px;
text-align:center;
font-size: 3em;
color: #fff;
mix-blend-mode: difference;
}
<div>
<h2>THIS IS SOME TEXT YYEY</h2>
</div>
If you don't want to be at the mercy of old browsers which don't support mix-blend-mode and have absolute control over your text color you could use data-* attribute:
$("[data-textcolor]").css("color", function() {
return this.dataset.textcolor;
});
body{background:#C0FFEE;}
<div class="fullscreenslideshow">
<div style="background-image:url(image1)" data-textcolor="#fff">SLIDE1</div>
<div style="background-image:url(image2)" data-textcolor="#000">SLIDE2</div>
<div style="background-image:url(image3)" data-textcolor="rgba(0,0,0,0.4)">SLIDE3</div>
<div style="background-image:url(image4)" data-textcolor="red">SLIDE4</div>

I am trying to create a sticky menu using CSS Bootstrap affix and list-group menu.
I manage to get most of it to work except for when the user scrolls down.
When the user scrolls down, the menu seems to take the entire with of the page.
I tried to set it up via data attributes
using something like this
<div class="container">
<div class="row">
<div class="col-md-3" id="leftCol">
<div data-spy="affix">
<div class="list-group list-group-root well">
<a class="list-group-item" href="#introduction">Introduction</a>
<a class="list-group-item" href="#features">Features</a>
<a class="list-group-item" href="#dependencies">Dependencies</a>
</div>
</div>
</div>
<div class="col-md-9" id="mainCol">
Some long text for the body along with some tables.
</div>
</div>
</div>
But the data attribute did not make the menu stick! it just kept it on the top.
So I tried to use JS to get the job done like this
$(function(){
$('#leftCol').affix({
offset: {
top: 100,
bottom: function () {
return (this.bottom = $('.footer').outerHeight(true))
}
}
});
});
I created jsFiddle to show you the current behavior.
How can I fix this affix so when the user scrolls down the menu maintain the same shape?
First of all, you should use either data-attributes or JS.
I updated your jsFiddle. The position of id="leftCol" was changed:
<div class="col-md-3" >
<div id="leftCol">
...
</div>
</div>
and style was added:
#leftCol {
width: 220px;
}
Also, you should add media queries to remove affix from mobile view.
As an "unacceptable" workaround, I set a max width of the menu to 250px like so
.list-group.list-group-root {
padding: 0;
max-width: 250px;
}
I am not sure how to get it to work without adding a max-with the max with should be defined by the parent. In this case class="col-md-3"
UPDATED
javascript to the rescue!
I added the following JS code to solve this problem once an for all.
It basically resize the menu everytime affix.bs.affix event is fired
$(document).on('affix.bs.affix', '#docs-menu', function() {
$(this).width($(this).width());
});
From the docs
affix.bs.affix => This event fires immediately before the element has
been affixed.
Ok I believe I got most of the code working like you want it to. The main changes I made were adding this CSS:
#leftCol {
display: block;
height: auto;
padding: 0;
width: 100%;
}
.navbar-fixed-top-again {
position: static;
top: 60px;
z-index:1031;
}
.navbar-inner {
background: red;
padding: 5px;
}
.affix {
position: fixed !important;
}
and I changed up some of the structure on your HTML:
<div class="container body-content">
<div>made up content to allow the navigation to scroll more before it becomes sticky. This height will need to be set in the data-offset-top which is in the leftCol DIV just below this content. The same will apply if you need to set it for a footer offset.</div>
<!-- new nav section -->
<div class="col-md-3 navbar-fixed-top-again" id="leftCol" data-spy="affix" data-offset-top="80">
<div class="navbar-inner">
<div class="list-group list-group-root well">
*the rest of your code*
</div>
</div>
</div>
</div>
The main problem now is having a sticky navigation menu with variable height. If you notice when you scroll your reading content underneath jumps up and gets hidden. It seems that it is possible to fix this using JavaScript (link to SO question).
Heres the link to your updated Fiddle. Hope that helps.
The issue is the following :
I have a calendar in which the user can create an appointment (using DHTMLX Scheduler Timeline View), the main problem is the Scheduler doesn't support a scrollable view , only fits the schedule into the view.
I Solve the previous problem, creating a div with a FIXED width (in this way can i have a longer horizontal scheduler ) and wrapping it inside a div that allows to scroll horizontally its content.
However , I dont have a clear idea of how to solve the following problem caused :
When the calendar is loaded , you can see which div belongs to its horizontal Row
And when the user scrolls horizontal (to see 7:00 PM for example)
You cannot see in which div with color you need to create the appointment !
So i need something like this, where the div is still visible although the user scrolls horizontally :
I already tried with something like the following :
May be a problem too with the parent container, because it hides the div if the following works maybe ?
.visible-division{
position:relative; /*Because the div with color is inside a table, and i need that still floating in the same row !!*/
float:left;
z-index:9000;/*a higher z-index in case something cover the div*/
}
without any luck ..
My CSS
#calendar-container{
width: 2000px;
}
#calendario {
height: 900px;
width: 100%;
border: 1px solid #cecece;
}
.scrolling_container {
height: 100%;
overflow: auto;
}
And my Markup
<div class="scrolling_container">
<div id="calendar-container">
<div class="dhx_cal_container panel" id="calendario">
<div class="dhx_cal_navline">
<div class="dhx_cal_prev_button"> </div>
<div class="dhx_cal_next_button"> </div>
<div class="dhx_cal_today_button"></div>
<div class="dhx_cal_date"></div>
<div class="dhx_cal_tab" name="day_tab"></div>
<div class="dhx_cal_tab" name="week_tab"></div>
<div class="dhx_cal_tab" name="month_tab"></div>
<div class="dhx_cal_tab" name="timeline_tab" style="right:280px;"></div>
</div>
<div class="dhx_cal_header"></div>
<div class="dhx_cal_data"></div>
</div>
<div class="well text-right">
<div>
a link
</div>
</div>
</div>
It can be solved via CSS ? Otherwise, Should I apply classes to it in case of scroll event ?
Any help is appreciated, thanks !
This may help you do the trick.
.visible-division{
position:fixed;
width: /* specifiy */
height: /* specify */
top: /* specify */
left: /* specify */
}
.scrolling_container {
height: 100%;
overflow: auto;
}
Though not supported by most browser, you may try sticky position value position: sticky.
Hope this will be helpful, apply this class to the floating div only.
.floating{
position:fixed;
top:20px;
right:0px;
width:80%; /* as required */
}
I have a number of DIVs currently laid out in an oval shape. Each div represents a "service" and is ID'd accordingly, all are set with an absolute position.
What I am wanting to do is on mouseover of a div, I want to have a new DIV with relevant information appear in the middle. This should happen for each "service" so each "descriptive" div will be hidden until mouseover but all appear in the same space.
The website in question is the home page of www.faa.net.au.
How do I go about making this new descriptive DIV appear on mouseover and hide on mouseout?
What you can do is position all of those divs in that spot in the middle with CSS. They can stack and the z-index doesn't matter since all you'll only see one at a time. Then hide them with "display:none" in your CSS.
Then use jQuery's .hover() method to show those the appropriate div on mouseover
$("#idOftheDivYouHoverOn").hover(function (e) {
//This funciton defines what happens on mouse-in or hover.
$("#idOfTheDefaultCenterDiv").hide();
$("#idOfTheDivYouWantedToShow").show();
}, function (e) {
//This function defines what happens on mouse-out or when the hover is over.
$("#idOfTheDefaultCenterDiv").show();
$("#idOfTheDivYouWantedToShow").hide();
});
You'll have to do this for each one you hover on. There is a "smarter" way but it would be a very long answer to explain it.
That is if you want to do this using JavaScript/jQuery instead of just plain CSS similar to the ones you see in other answers. With this method you can add fading effects - take a look at jQuery's hover - http://api.jquery.com/hover/
Edit: Here's a working example: http://jsfiddle.net/6dMDS/
Hope that helps.
A friend in another forum just posted another way of doing this. Be warned it's CSS3 only so some browsers (and definitely older IE's) won't support it.
<div class="container">
<img class="one" src="http://placehold.it/100x100" />
<img class="two" src="http://placehold.it/100x100" /><br>
<img class="three" src="http://placehold.it/100x100" />
<img class="four" src="http://placehold.it/100x100" /><br>
<img class="five" src="http://placehold.it/100x100" />
<img class="six" src="http://placehold.it/100x100" />
<div class="hidden-one">hidden-one</div>
<div class="hidden-two">hidden-two</div>
<div class="hidden-three">hidden-three</div>
<div class="hidden-four">hidden-four</div>
<div class="hidden-five">hidden-five</div>
<div class="hidden-six">hidden-six</div>
</div>
* {margin: 0; padding: 0;}
.container {width: 400px;}
.one:hover ~ .hidden-one,
.two:hover ~ .hidden-two,
.three:hover ~ .hidden-three,
.four:hover ~ .hidden-four,
.five:hover ~ .hidden-five,
.six:hover ~ .hidden-six
{display: block;}
.hidden-one,
.hidden-two,
.hidden-three,
.hidden-four,
.hidden-five,
.hidden-six
{
width: 200px;
height: 300px;
border: 1px solid red;
display:none;
float: right;
position: relative;
top:-305px;
left: 10px;
}

So if I got it right, you got a "service" DIV and a "descriptive" DIV. Try some CSS to make it happen.
HTML:
<div id="service"></div>
<div id="descriptive"></div>
And CSS:
#descriptive
{
visibility:hidden;
}
#service:hover #descriptive
{
visibility:visible;
}
Basically this will make the DIV with id="descriptive" be shown when id="service" is hovered.
