I'm currently building a popup box script using css/jquery and i can't seem to get the div centered on the screen on all cases. It it possible to center it without knowing the div width?
Instead of posting all the code here i put up a live example at http://goo.gl/N45cp
Any kind of help is much appreciated!
Best Regards
John
<div id="wrapper">
<div id="child"></div>
</div>
If the position of the #child is not absolute, you can set left and right margins to auto:
#child {
margin: 0 auto;
}
Or if the position is absolute you can try the following:
$("#child").css("left", function(){
return ($("#wrapper").width() - $(this).width()) / 2;
});
You can achieve this with pure CSS if you have a containing div:
HTML
<div id="outer">
<div id="inner">some content here</div>
</div>
CSS
body, html, div#outer { height:100%; }
div#outer { text-align:center; }
div#inner { display:inline-block; }

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'm creating DIVs dynamically and appending them to a particular DIV.
My question is how do I always make the last created DIV to be above other DIVs within the appended (its parent) DIV?
So basically I want the last created DIV to be on the top level of the other.
DIV 4 - [created at 4:32pm]
DIV 3 - [created at 4:29pm]
DIV 2 - [created at 4:27pm]
DIV 1 - [created at 4:26pm]
the dynamic DIV css:
.dynamicDIV{
width:100%;
position: relative;
}
the append DIV css:
.parentDiv{
width: 100%;
margin-top: 5px;
}
I'm not referring to the z-index. I want to position it above the others.
var parentElement;
var newFirstElement;
parentElement.insertBefore(newFirstElement, parentElement.firstChild);
As I pointed out in my comment, .prepend() can be used here:
$('.parentDiv').prepend('<div class="dynamicDIV">New Div</div>');
but there is a second possibilty:
$('<div />').addClass('dynamicDIV').text('New Div').prependTo('.parentDiv');
This solution is a bit more maintainable.
Demo
Reference
.prepend()
.prependTo()
Use .prepend() on whatever element you want to be preceeded with the new one:
http://api.jquery.com/prepend/
When a DIV is at position: absolute, the last sibling in the DOM is over the others. This doesn't depend on the time you inserted it.
But you can override this behavior by using z-index: 1.
Look at this HTML code:
<style>
div.container > div {position: absolute; z-index: 0}
div#C {z:index: 7}
</style>
<div class="container">
<div id="A">A</div>
<div id="B">B</div>
<div id="C">C</div>
<div id="D">D</div>
</div>
This code will display C hidding D, hidding B, hidding A.
CSS with display:flex and flex-direction:column-reverse; can help you:
body {/* parent container of div to shw in a reverse flow*/
display:flex;
flex-direction:column-reverse; /* row-reverse if on line*/
}
div {
width:50%;
border:solid;
margin:auto;
}
div:last-of-type:after {
content:'last in document !';
color:red;
}
<div> 1 </div>
<div> 2 </div>
<div> 3 </div>
<div> 4 </div>
anyway, in the DOM or for CSS selector, last will be last. reverse order only shows at screen.
Okay so I have a page that uses javascript to fix the header to the top of the page (thus removing the banner) when you scroll past the bottom of the banner (about 200px down page).
On this website I've been using containers that have the position:inherit; property set to contain each part of the page. These then have a relatively positioned element inside them so I can place all my absolutely positioned elements where I like.
My problem is that id="content" keeps jumping to the top of the page when the javascript changes id="header" to position:fixed;
See here: www.obsojb.com
I have tried absolutely positioning id="content" and setting it's top value but it wouldn't work and I'm a bit stuck.
Here is a very simplified version of the HTML:
<body>
<div id="page"> <!--inherit-->
<a id="banner"></a> <!--inherit-->
<div id="header"> <!--inherit-->
<div id="lang"> <!--relative-->
<ul>...</ul> <!--inherit-->
<other divs> <!--absolute-->
</div>
<div id="nav"> <!--relative-->
<ul>..</ul> <!--inherit-->
<a id="userbutton"></a> <!--absolute-->
</div>
</div
<div id="content0"> <!--inherit-->
<div id="content"> <!--relative-->
<PAGE CONTENT> <!--absolute-->
</div>
</div>
<div id="footer"></div>
</div>
</body>
Here is my javascript:
var bannerheight // Glob var
window.onload = function() {
window.bannerheight = $('#bannerimg').height();
checkOffset();
};
window.onscroll = function(oEvent) {
checkOffset();
}
function checkOffset() {
if (window.pageYOffset >= window.bannerheight) {
document.getElementById("header").style.position = "fixed";
document.getElementById("banner").style.display = "none";
document.getElementById("padding").style.height = window.bannerheight+"px";
}
else {
document.getElementById("header").style.position = "inherit";
document.getElementById("banner").style.display = "block";
document.getElementById("padding").style.height = "0px";
}
}
and here is the relevant CSS:
#page {
margin:0px auto;
}
#lang {
position:relative;
}
#nav {
position:relative;
margin:0px auto;
}
#content0 {
height:800px;
}
#content {
position:relative;
margin:0px auto;
}
Try giving the content div a "margin-top" and set it to the number of pixels that the page is "jumping". Then when you scroll up and reset the position, undo the margin-top back to zero.
I've tested this and it solved my jumping issue.
I'm not sure what you expect as output but position: fixed works on the document, globally. It not only ignores element flow (like position: absolute) but it also ignores scrolling.
position: absolute is relative to it's offset parent which can be an item with position: relative.
You typically only want to use position: fixed if something needs to stick to the window, like a little popup that scrolls with as you go down the page. The Facebook header is a good example. Their header bar is fixed to the top of the window and stays there even if you scroll.
My div has a styling position:absolute, and as a result, it doesn't expand if the content is higher than it's height.
Therefore, I thought that a solution would be if I find what the is the actual content's height, and assign the height to the div with the position:absolute styling.
Any idea how to do it? or maybe an idea how to make an absolute div to expand according to its content.
Thanks in advance!
Element.scrollHeight should do the job.
Here's an awful way to get the height of the container. We're basically cloning the whole div, setting the position so that it has height, checking that height, and then removing it:
$(function () {
var clone = null;
alert( clone = $('.test').clone().css('position', 'static').appendTo(".container").height());
clone.remove();
});
Here's the fiddle: http://jsfiddle.net/vPMDh/1/
It should expand even if being absolute.
check you don't have a height: xxpx
if so, change it to min-height
As you've said "it doesn't expand if the content is higher than it's height." I guess you have a fixed height set on it.. if you do need this for some reason try using min-height instead.
Have a look at this fiddle.
<div class="classname">
Some content....
<p style="clear:both"> </p>
</div>
use a clearfix hack. heres the link
and add clearfix to you div
example
in your style sheet
<style>
.clearfix:after {
content: ".";
display: block;
clear: both;
visibility: hidden;
line-height: 0;
height: 0;
}
.clearfix {
display: inline-block;
}
html[xmlns] .clearfix {
display: block;
}
* html .clearfix {
height: 1%;
}
</style>
...
and in your div add clearfix the class
<div class="clearfix">
//some html tags
</div>
Thanks for contributing your question. If you use this:
$(document).ready(function(){
var x = $("#container").height();
alert(x);
//if not works then
var y = $("#container").outerHeight();
alert(y);
});
I think it is easy as clean code to find the height of any div if you do not apply the div's height too.
similar solution to #MattDiamant, but with vanilla JS and without creating a clone:
function getDivHeight(posAbsoluteDiv) {
const heightBackup = posAbsoluteDiv.style.height;
posAbsoluteDiv.style.height = 'auto';
const contentHeight = posAbsoluteDiv.getBoundingClientRect().height;
posAbsoluteDiv.style.height = heightBackup;
return contentHeight;
}
I want to achieve hide/show with div's in html but in this way.
Here is my html:
<div id="left"></div>
<div id="middle">
<input type="button" id="button"/>
</div>
<div id="right"></div>
And this is my css:
body
{
height: 100%;
margin: 0;
padding: 0 ;
border: 0 none;
}
#left
{
background-color:#EEEEEE;
height:570px;
width:73.9%;
float:left;
}
#center
{
background-color:#D4EAE4;
color:#535353;
height:570px;
width:15.25%;
float:left;
margin:0;
}
#right
{
background-color:#D4EAE4;
float:left;
width:11%;
height:570px;
margin:0;
}
I want to do that when I click button on div center to hide div right and to expand divleft for the size of the div right and then move div center all the way to the right. I want to hide/show them with horizontal animation, such as from left to right or right to left.
Playing with the words can be tricky so I made a little pictures so you can actually see what am I talking about:
Start phase:
And end phase:
You can see a working demo here... http://jsfiddle.net/miqdad/3WDbz/
or you can see other demo which increment width of first div here .. http://jsfiddle.net/miqdad/3WDbz/1/
I had almost the same question a couple of days ago and maybe it helps you too.
this example uses a checkbox to hide the div. and make the other div 100% width.
javascript, When right div is hidden left div has to be 100% width.
the javascript code from the example:
$(function() {
$("#foo").on("click",function() {
if ($(this).is(':checked')) $('#checked-a').show('fast',function() {
$('#checked-b').css("width","60%");
$('#checked-a').css("width","40%");
}) ;
else $('#checked-a').show('fast',function(){
$('#checked-b').css("width","100%").show();
$('#checked-a').css("width","0%").hide();
});
});
});
and an example:
http://jsfiddle.net/mplungjan/5rdXh/
This is one of the best ways to hide a div element using JavaScript:
<html>
<head>
<script>
function hideDiv() {
document.getElementById("myP2").style.visibility = "hidden";
}
</script>
</head>
<body>
<button onClick="hideDiv()">Hide</button>
<br>
<br>
<p id="myP2">Hello world!</p>
</body>
</html>
Implementing with JQuery is easy. Have a look at this JSFiddle example: http://jsfiddle.net/q39wv/2/
(To all: Normally I wouldn't put only a JSFiddle link here, but this time I think it's worth showing the OP how the whole thing works, with some adjustments to his HTML and CSS).
A Javascript-only solution would be much more difficult to implement.
