<style type="text/css">
.collapse {
height: auto;
width: auto;
}
.collapse.in.width {
width: auto;
}
</style>
My horizontal collapse works fine however once collapsed I want the div class=span4 width to increase to the available viewport width space e.g: 8. and the button label to change to 'Show' and vice-versa using JQuery.
Just switch out the spanN class on the div when the collapse occurs using the event:
$('#demo').on('hidden', function () {
$('#your-content-div').removeClass('span4').addClass('span8');
});
See the section on events under http://getbootstrap.com/2.3.2/javascript.html#collapse

I am trying to create two divs where one of which is resizable and the other takes the remaining available space in the parent container which holds the two divs.
Using flexbox model, i placed both divs beside each other and gave the one on the left a with of 50% and the one on the right flex: 1 so it takes the available space.
I then used jquery-ui resizable function on the div by the left. But when i resize the div by the left, it only decreases on mouse drag and does not increase, neither does the div to the right decrease..
I am trying to archive something like that of codepen, with multiple resizable divs layed out vertically or horizontally
Here is my code
HTML
<div class="wrapper">
<div class="left-div" id="resizable"></div>
<div class="right-div">
</div>
CSS
.wrapper{
width: 100%; // 100% of the body
height: 100vh; // take the entire view-port height
display: flex;
}
.left-div{
position: relative
width: 50%; // 100% of the parent div(wrapper)
height: 100%;
}
.right-div{
position: relative
flex: 1;
}
JS
$(document).ready(function () {
$("resizable").resizable({
handles: "e",
autoHide: true,
maxWidth: ""
});
})
$(document).ready(function () {
$("#resizable").resizable({
resize: function(event, ui) {
ui.size.height = ui.originalSize.height;
}
});
})
Check out this CodePen
I added a function to lock the resizable along Y axis.
Also, remember to add # before id selector.
I am trying to place a position: absolute div inside a scrolling div and make it stay on the left when scrolling left or right. This is because I want the div to move like one unit (when scrolling left, right, top, bottom). It's working great on screen that lower then 2K but on HD screens (ie. 2k, 3k, 4k...) the child div is jumping around and looks bad.
Is there a better way to do it? What change should I make to the CSS for HD screens?
#parent {
overflow: auto;
width: 100%;
height: 100%;
position: relative;
}
#child {
overflow: hidden;
width: 20%;
height: 100%;
z-index:1;
position: absolute;
}
<div id="parent">
<div id="child"></div>
</div>
$("#parent").on('scroll', function (event) {
$("#child")[0].style.marginLeft = this.scrollLeft+"px";
});
You can use jQuery's css function to set the value. And use the parent element as jQuery object to use scrollLeft() function:
$("#parent").on("scroll", function() {
$("#child").css("margin-left", $(this).scrollLeft() + "px");
});
But I would not use jQuery for this at all. Why not use a fixed position in css for this? Like in this example. It should not flicker on any screen.
Let's say that we have body width of page set to 2000px with content centered horizontally inside of body with width set to 1200px.
<body>
<div class="content"></div>
</body>
CSS:
body {
width: 2000px;
}
.content {
position: relative;
width: 1200px;
margin-left: auto;
margin-right: auto;
}
What I am trying to achieve is that I do not allow horizontal scrolling at all until your
window size is 1200px or less (on resize) with setting overflow-x to hidden.
$(function() {
$(window).resize(function() {
if(window.innerWidth > 1200) {
$("body").css({
"overflow-x": "hidden"
});
} else {
$("body").css({
"overflow-x": "visible"
});
}
});
});
which works fine. But I also want to prevent user from scrolling further than 1200px if his window width is less than 1200px (problem here is that as soon as the window width is less than 1200px, it is possible to scroll to full width - 2000px).
So how would you solve this?
If I understand your question correctly then I believe this could be fixed by adding a max width style to your body tag. This eliminated side scroll for me.
body {
max-width: 2000px;
}
In this case you can use the scrollLeft proprerty:
onScroll = function (e){
var maxScroll=1200
if(e.target.scrollLeft>maxScrollLeft){
e.target.scrollLeft=maxScrollLeft
}
}
(I am looking for an HTML/CSS fix but if there really is none then JS (prefereably JQuery) works for me)
I have two main divs inside my page, I have the #maincontent and the #footer.
Basically, I want the footer to always sit at the bottom on the page:
#footer{
position:fixed;
bottom:0;
}
BUT I do not want it to overflow on the #maincontent when the page is too small.
For the sake of the question the page can be thought of as simple as:
<body>
<div id="maincontent">Dynamic Content</div>
<div id="footer">StaticContent</div>
</body>
My problem is that I can do one or the other, either I fix it to the bottom of the page but when I make the viewport < (footer + maincontent) the footer sits on top of the content. I want the footer to always be at the bottom of the page but disappear off page before it overtakes the main content.
Add a class to the footer with jQuery that changes it to position: absolute when the viewport is too small.
$(document).ready(function() {
var height = $(window).height();
function windowHeight() {
height = $(window).height();
}
windowHeight();
$(window).resize(function() {
windowHeight();
});
if (height < 600) { //arbitrary height value you can set yourself
$('#footer').addClass('not-fixed');
} else {
$('#footer').removeClass('not-fixed');
}
});
If you know your footer's height whatever happens to the window height, or its content :
Just add a "padding-bottom" to your body or main content that matches the footer's height.
If you don't know your footer's height. This is trickier, as you will probably need some javascript to calculate the height of the footer, the height of the main content, compare the sum of both with the window height, and if it doesn't fit, add some adequate bottom padding to the body / main content.
EDIT :
Ok I understand, I think this jsfiddle should do the trick : http://jsfiddle.net/ah4XA/2/
The javascript would be :
$(document).ready(function () {
function updateFooter () {
var footerH = $("#main-footer").height();
var contentH = $("#main-content").height();
var windowH = $(window).height();
if ( contentH + footerH > windowH) {
$("#main-footer").removeClass("fixed");
} else {
$("#main-footer").addClass("fixed");
}
}
$(window).resize(function () {
updateFooter();
});
updateFooter();
});
If I understand what you're looking for, you want the footer to stay on the bottom of the window regardless of the page content, but also not overlap the page as the window is resized vertically.
One possible solution is to switch between position:absolute; and position: fixed; with a media query. So past a certain height it's fixed, but below that the footer position:absolute;.
EXAMPLE FIDDLE
CSS:
#media all and (max-height:300px) {
#footer {
background: red; <- added for testing
position: absolute;
}
}
The only drawback to this approach is that you need to know the height to set the switchover to. This may be tricky, but position:fixed;.
The simplest solution would be to position footer at the bottom permanently and increase the z-index of your maincontent so that it comes over the footer if window size is decreased.
NOTE: This is not the only way to do this.
JSFIDDLE DEMO
Sample CSS
#maincontent{
height : 400px;
background-color : green;
/*
position : relative is added to enable z-index.
*/
position:relative;
/*
z-index will bring it above footer,
if window size is reduced.
*/
z-index: 1;
width : 100%;
}
#footer{
height : 100px;
width : 100%;
background-color : black;
/* Below two properties will
postion footer at the bottom of the page.
*/
position : fixed;
bottom : 0;
color : white;
}
You should play with CSS position property to get this done.
EDIT:
Here is another CSS solution :
The maincontent and footer are wrapped in a bodyContainer div its position is set to relative and then footer is positioned w.r.t it.
JSFIDDLE DEMO 1 Footer is below body and not shown.
JSFIDDLE DEMO 2 Footer is shown since body height is less.
HTML
<div id="bodyContainer">
<div id="maincontent">Dynamic Content
</div>
<div id="footer">StaticContent</div>
</div>
CSS
#bodyContainer {
min-height: 100%;
position: relative;
}
#maincontent{
height : 800px;
background-color : green;
padding-bottom: 60px;
width : 100%;
}
#footer{
background-color: black;
bottom: 0;
color: #FFFFFF;
height: 48px;
position: absolute;
width: 100%;
}
I am working on javascript scroll. I have following html code
JSFIDDLE
<div class="wrapper">
<div class="red div current"></div>
<div class="blue div"></div>
<div class="green div"></div>
<div class="yellow div"></div>
</div>
In above code I have four div tags red, blue, green and yellow. All of them are position in following css.
html, body {
height: 100%;
}
.wrapper {
overflow: hidden;
height: 100%;
}
.div {
position: relative;
height: 100%;
}
.red {
background: red;
}
.blue {
background: blue;
}
.green {
background: green;
}
.yellow {
background: yellow;
}
In above html and css the red div tag is the current one which means user is seeing the red div tag on the screen. Now what I am trying to do is when user scroll over window once, then the next div tag i.e. blue will be animated and moved to the top and will become visible to the user whereas the red div tag will be behind the blue one. This same process goes for both green and yellow.
The problem is that when user scroll once then the div tag should animate however my current javascript code is keep reading the scroll and animating the div tags one after another. What I want is when user scroll once then scroll should be disabled until the blue div tag is animated. Then scroll should be enabled. Again when user scroll second time, the scroll should disable until the green div tag completes its animation. Same goes for yellow.
How can I achieve above?
Here is my javascript
$(window).on("scroll", function () {
var next = $('.current').next();
var height = next.outerHeight();
next.animate({top: '-=' + height}, 500, function () {
$(this).prev().removeClass('current');
$(this).addClass('current');
});
});
Please have a look on update JsFiddle
$(window).on("scroll", function () {
var next = $('.current').next();
var height = $('.current').outerHeight();
$('.current').prevAll().each(function(){
height += $(this).outerHeight();
});
next.animate({top: '-=' + height}, 500, function () {
$(this).prev().css('top','');
$(this).prev().toggleClass('current');
$(this).toggleClass('current');
});
});
The main reason your example wasn't working as expected is because you were relatively positioning the divs, and not moving them to the correct spot.
Working JSFiddle:
http://jsfiddle.net/seanjohnson08/rVVuc/6/
.wrapper {
overflow: hidden;
height: 100%;
position: relative;
}
.div {
position: absolute;
height: 100%;
width: 100%;
top: 100%;
}
.current{
top: 0;
}
If you are looking for a way to limit the amount of scroll events fired, try throttling: http://benalman.com/projects/jquery-throttle-debounce-plugin/. My solution doesn't require this, because no matter how many times it is firing the scroll event, it only ever tells jquery to animate to top:0, there's no chance of it animating past that.
