enlarge images with hover on slider bootstrap3 Slide Carousel - javascript

I view this code sample to enlarge an image.
I try used it in bootstrap3 Slide Carousel.
I try add 'enlarge' class bootstrap3 slide carousel items.:
<div class="item active">
<div class="item-item col-md-3 col-sm-4">
<a href="#">
<img src="http://placehold.it/500/bbbbbb/fff&text=1" class="img-responsive enlarge">
</a>
</div>
</div>
css:
.enlarge {
width: 100%;
float: left;
-webkit-transition: all 0.5s ease-in-out;
-moz-transition: all 0.5s ease-in-out;
transition: all 0.5s ease-in-out;
}
.enlarge:hover {
width: 120%;
-webkit-transition: all 0.5s ease-in-out;
-moz-transition: all 0.5s ease-in-out;
transition: all 0.5s ease-in-out;
cursor: pointer;
}
you can see change here in jsfiddle.
but it can not enlarge.how can I do it?

The issue is that, if you want to increase the width of the image to suppose 120%, the increase will work perfectly fine. But bootstrap.min.css has the following style properties for img element.
CSS:
.img-responsive {
display: block;
height: auto;
max-width: 100%;
}
Thus you are not able to scale above 100% if you add the class.
.carousel .img-responsive{
max-width:none;
}
It will override the CSS in bootstrap, if you any reason you are not able to view the changes you can add !important, which will override on priority.
.carousel .img-responsive{
max-width:none !important;
}
This will apply to all the images under the carousels.
If you want to specify only for one carousel, you can specify the ID of the carousel, like
#myCarousel .img-responsive{
max-width:none;
}
Here is a working DEMO.

CSS transition of a div does not animate

When I click a div, I want a second div to expand/collapse. That is done using JS, HTML, and CSS. Now I want the CSS transition to animate.
Right now all I get is a jumping expansion and either a scroll (Edge) or a jump after a wait (Chrome, Opera, Firefox).
I've tried to set height to 1px instead of 0px, but that doesn't change anything.
function growDiv(id) {
var ele = document.getElementById(id);
if (ele.style.height == '100%') {
ele.style.height = '0px';
} else {
ele.style.height = '100%';
}
}
.main {
font-weight: 700;
overflow: hidden;
cursor: pointer;
}
.secondary {
-webkit-transition: height .5s ease;
-moz-transition: height .5s ease;
-ms-transition: height .5s ease;
-o-transition: height .5s ease;
transition: height .5s ease;
overflow: hidden;
padding-left: 20px;
height: 0px;
cursor: pointer;
}
<div class="main" onclick="growDiv('expandable')">
Expand
</div>
<div class="secondary" id="expandable" onclick="growDiv('expandable')">
number1,
<br>number2,
<br>number3,
<br>number4.
</div>
Codepen behaves as I know the full site does, so for good measure; here's the codepen: http://codepen.io/anon/pen/ezJQjM
From http://css3.bradshawenterprises.com/animating_height/
Instead of using 100%, just "let it" get the auto value by not restraining it.
NOTE: 100px is just "any number bigger than the actual size"
function growDiv(id) {
var ele = document.getElementById(id);
if (ele.style.maxHeight != '0vh') {
ele.style.maxHeight = '0vh';
} else {
ele.style.maxHeight = "100vh";
}
}
.main {
font-weight: 700;
overflow: hidden;
cursor: pointer;
}
.secondary {
-webkit-transition: all .5s ease;
-moz-transition: all .5s ease;
-ms-transition: all .5s ease;
-o-transition: all .5s ease;
transition: all .5s ease;
overflow: hidden;
padding-left: 20px;
cursor: pointer;
}
<div class="main" onclick="growDiv('expandable')">
Expand
</div>
<div class="secondary" id="expandable" onclick="growDiv('expandable')" style="max-height: 0vh;">
number1,
<br>number2,
<br>number3,
<br>number4.
</div>
EDIT: Changed everything to VH (viewport height) so it will never grow bigger than 100% of the screen height and will adapt to the max height of any screen.
Also switched the "style="max-height: 0vh;" to the element itself instead of the class, so you could be unsetting it with ele.style if needed (otherwise you will need to set a new value to override the class.
Are you willing to use jQuery? It offers some cool animation possibilities, and may accomplish what you are trying to do. This is just a possible alternative to your approach.
Check out my fiddle here:
https://jsfiddle.net/3mo28z1t/11/
<div class="main" id="clicker">
Expand
</div>
<div class="secondary" id="expandable">
number1, <br> number2, <br> number3, <br> number4.
</div>
<script>
$( document ).ready(function() {
$(".secondary").hide();
$(document).ready(
function(){
$("#clicker").click(function () {
$(".secondary").toggle("slow");
});
});
});
</script>
The problem is caused by switching units of measure, so from pixels to percent. I would probable do it a little differently though.
growDiv = function(id) {
document.getElementById(id).classList.toggle('expanded');
}
.main {
font-weight: 700;
overflow: hidden;
cursor: pointer;
}
.secondary {
transition: max-height .5s ease;
overflow: hidden;
padding-left: 20px;
max-height: 0;
cursor: pointer;
}
.secondary.expanded {
height: 100%;
max-height: 100px;
}
<div class="main" onclick="growDiv('expandable')">
Expand
</div>
<div class="secondary" id="expandable" onclick="growDiv('expandable')">
number1,
<br>number2,
<br>number3,
<br>number4.
</div>
You'll notice the JS is a bit simpler, and it relies more on the CSS.

jQuery: Is it possible to use slideUp and append text at the same time?

When a user mouses over a picture, I want to slideUp a description, so that new text will appear. When the user mouses out, the description will slideDown.
This is what I've tried so far:
$pic1.hover(function () {
var text1 = $("<div>Price1:$100</div>").hide();
text1.appendTo($('.this')).slideUp("slow");
},function () {
$(this).slideDown();
}
);
Unfortunately, this doesn't work. I googled around, but couldn't find anything. Is it possible to use slideUp and slideDown to show and hide the text?
A better approach would be to use CSS transitions. They're lightweight and easy to do. You can read the specification on transitions here. Here is a quick guide on the matter.
fiddle
HTML
<div class="imageDiv">
<img src="http://placekitten.com/g/200/300" />
<div class="imageDescription">
What a lovely kitty kat!
</div>
</div>
CSS
.imageDiv {
display: block;
float: left;
overflow: hidden;
position: relative;
width: 200px;
}
.imageDescription {
-webkit-transition: top 0.5s ease;
-moz-transition: top 0.5s ease;
-ms-transition: top 0.5s ease;
-o-transition: top 0.5s ease;
transition: top 0.5s ease;
background: rgba(0, 0, 0, 0.4);
color: #f7f7f7;
left: 0;
position: absolute;
text-align: center;
text-decoration: none;
top: 100%;
width: 100%;
}
.imageDiv:hover .imageDescription {
display: block;
top: 93%;
}
There a few key things that make this work. First, a CSS transition is used. Transitions are written in the following form:
transition: [property] [duration] [timing-function] [delay];
As can be seen in the example above, I used a transition that targeted the top attribute. I gave it a 0.5s duration and an ease effect. However, this alone wouldn't produce the effect, as the description would just sit below the image and move up on hover. We don't want to see the description until the user hovers over the image!
To address this, you need to add overflow: hidden; to the parent div.imageDiv. This hides the image description, until the transition, when it will be slide up, causing it to no longer overflow.
http://jsfiddle.net/qvbgb/3/
HTML
<div class="imgcontainer">
<div class="image">
<img src="link.jpg" />
</div>
<div class="text">
<h3>Product name</h3>
<p>Description</p>
</div>
</div>
Jquery
$(document).ready(function(){
$('.text').hide();
$('.container').hover(
function () {
$(this).find('.image').slideUp();
$(this).find('.text').slideDown();
},function () {
$(this).find('.text').slideUp();
$(this).find('.image').slideDown();
}
);
})
CSS
.container{
min-width : 150px;
min-height : 150px;
width : 150px;
height : 150px;
cursor : pointer;
display : block;
}
.image img{
width : 150px;
height : 150px;
}
slideUp() will only hide an element, and slideDown() will only show an element. If you want to show an element with slideUp effect or hide with slideDown effect, you have to explicitly call it:
$(text1).show("slide", { direction: "up" }, 1000);
$(text1).hide("slide", { direction: "down" }, 1000);

How to make my off-canvas menu scroll?

I've been trying to get my off-canvas menu working by scrolling particularly in landscape mode because the list itself runs longer than the size of the screen. This menu is shown below 768px for tablet and mobile.
To clarify, the menu items go longer then the screen space and I'm trying to get it to scroll by doing multiple methods, such as overflow-y: scroll, -webkit-overflow-scrolling: touch and more (all works in desktop browser at phone sizes when I was messing in the inspector).
I've been trying everything to inspect the elements and get the menu to scroll when needed and not the background (website/page behind menu). Here is some of my markup and styling, I'm also including a live link to inspect as its way easier than pasting everything in here. Any help is kindly appreciated!
LIVE LINK
<body class="cbp-spmenu-push">
<nav class="cbp-spmenu cbp-spmenu-vertical cbp-spmenu-left mobile" id="cbp-spmenu-s1">

cbp-spmenu has a min-height of 550px. This is what is limiting your ability to scroll it in smaller resolutions.
Remove the min-height and you should be fine. Of course, do it as a media query, so it only is in effect on mobile devices.
-----------update----------------
not sure if you just changed it, but I took another look and now I don't see the min-height, but adding overflow:auto to the same cbp-spmenu element also makes it scroll.

Show icon font on image center on mouse hover

I´m trying to do an effect and show a search icon font when the mouse hover my "image1.png".
I already did the effect with jQuery but now I do not see how I can integrate the iconic font with jquery. Has anyone done something like that? Can you give a little help?
<article id="loop-news">
<span id="testIcon"><I class = "fa fa-search-plus" > <!--show just on mouse hover -->
<img src="image1.png" id="test" />
<h2>Title </h2>
<p>My Post</p>
</article>
My css to hide icon font at first:
#testIcon>i{display:none;}
My jquery to give an opacity effect:
$("#test").hover(function() {
$(this).animate({opacity: 0.5}, 500);
}, function() {
$(this).animate({opacity: 1.0}, 500);
});
I would use CSS3 transitions if I understand your issue. In this example, I would just replace the font-family with your icon font (assuming that's how it works - never used it).
h2 {
position: aboslute;
margin-top: -350px;
display: none;
text-align: center;
font-family: arial;
}
#loop-news:hover h2 {
display: block;
}
#loop-news:hover img {
opacity: .5;
}
img, h2 {
-webkit-transition: all .8s ease;
-moz-transition: all .8s ease;
-ms-transition: all .8s ease;
-o-transition: all .8s ease;
transition: all .8s ease;
}

Toggle divs with pure JS

The scenario: one main container, a child img with opacity 1 and a child span with opacity 0, both absolute positioned against the relative positioned parent div. Decrease the opacity of img and simultaneously increase the opacity of span. When the opacity exceeds some threshold, e.g. 0.01 and 0.99 hide/show (display: none; display: inline-block) the img/span respectively. And then the reverse process to show the img and hide the span. What would be the best solution (probably using CSS3) to achieve that?
<div id="post-cont">
<img id="post-img-1" class="post-img" src="small.jpg"/>
<span id="post-txt-1" class="post-txt">Some text</span>
</div>
Had some workaround with JS, but it is laggy so I would like to solve this using CSS3 and as minimal JS as possible.
CSS3 only
http://jsfiddle.net/SPmj5/7/
<div id="post-cont">
<img id="post-img-1" class="post-img" src="http://placehold.it/250x250"/>
<span id="post-txt-1" class="post-txt">Some text</span>
</div>
#post-cont {
position: relative;
}
#post-cont img,
#post-cont span {
display:block;
-o-transition: opacity .7s ease;
-ms-transition: opacity .7s ease;
-moz-transition: opacity .7s ease;
-webkit-transition: opacity .7s ease;
transition: opacity .7s ease;
}
#post-cont img {
position: absolute;
top: 0;
left: 0;
opacity: 1;
}
#post-cont span {
position: absolute;
top: 100px;
left: 80px;
opacity: 0;
}
#post-cont:hover img {
opacity: 0;
}
#post-cont:hover span {
opacity: 1;
}
Be aware transition is not supported in IE8/9 http://caniuse.com/#search=transition
Sounds like some fadeToggle to me! I don't think you can use pure CSS3 for this..
