covers another div with div height of 100% - javascript

I've been trying layout with css the div (dark blue) so that changes size according to the size of the window without covering the bottom panel, I thought that with the height to 100% official, but not understand because it ignores the panel below, and ends moving off the page
now that see not let me post pictures, so something is also what I have:
html:
<div id="container">
<div id="message">hi i'm a message</div><!--i can see this div-->
<div id="darkBlue"></div>
<div id="anotherPanel">you can't see me</div>
</div>
and this css
#container{//This container is attached to the right side
right: 0;
width: 300px;
position: fixed;
height: 100%;
top: 0;
color: white;
padding: 20px;
}
#darkBlue{//this div cover the next div
height: 100%;
border: 1px solid white;
background: #3a5193;
bottom: 100px;
}
#anotherPanel{//i can't see this div.......
height: 100px;
botton: 0px;
}
Not sure if you can solve with css, or have to resort to using javascript (which is something I want to avoid), anyone knows some property who can help me?
UPDATE: This is the picture of what layout attempt: https://www.dropbox.com/s/t9nl5mb3sq85m3j/repro.png

Using bottom top left right you must define position. In your case remove bottom from #darkBlue #anotherPanel and add to #darkBlue height: calc(100% - 100px)
DEMO
Update
If you don't want to use calc then add margin-bottom:-100px; to #darkBlue
DEMO

You have a typo in the CSS of anotherPanel. You have botton instead of bottom. Also when using this CSS properties, is good to set the position.
Try this:
#anotherPanel{
height: 100px;
width: 300px;
bottom: 0px;
background: #F00;
position:absolute;
}
Is this the droid you are looking for?
Best.

If you assign a height of 100% to a child element it will take up 100% of the height of the parent element. If you want the element to cover the whole container without being in the document flow of the parent element you can try to do the following:
#darkBlue {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: #3a5193;
}
Edit: #Niels has mentioned an additional detail I've not mentioned before. For this to work the parent elements position needs to be set to either fixed, absolute or relative

How to set css position 'top' relative to document height instead of viewport height? [duplicate]

This question already has answers here:
Position absolute but relative to parent
(5 answers)
Closed 3 years ago.
I will try to make my question more clear.
Because I used below setting on Html body, I need to scroll the page down to get to page bottom.
body { height: 180vh;}
And I want to set a div position top property relative to document height, so that I can control its position at a place only visible when I scroll down. I prefer to set it by percentage value so that code will adapt different sizes of devices.
But by default the top property is relative to viewport, so I can not realize it by setting top value.
Is there a way to realize what I want to do? even not by top property.
If you give the body a position: relative and the div a position: absolute, you can set the top property as a percentage, where top: 100% will position it at the bottom of the page:
body {
height: 180vh;
background: lightblue;
position: relative;
}
div{
height: 30px;
width: 140px;
border: solid 2px gray;
background: white;
position: absolute;
top: 100%;
}
<div></div>
If i understand your question correctly, there are 2 ways
use padding-top
use position:absolute and top
code snippet below:
body {
height: 180vh;
}
.myDiv1 {
margin-top: 110vh;
height: 100px;
width: 100%;
background: lightblue;
}
.myDiv2 {
position: absolute;
top: 150vh;
height: 100px;
width: 98%;
background: lightpink;
}
<body>
<div class='myDiv1'></div>
<div class='myDiv2'></div>
</body>
First you need to make sure that the position property of the body is relative, absolute or fixed.
You can then set the position: absolute to make the element be dependent on the last parent element that had one of three properties mentioned above.
Finally you can set your top, left, right and bottom properties after that.
body {
height: 180vh;
position: relative;
}
#down {
position: absolute;
// or bottom: 10%;
bottom: 25px;
}
<div id="down">Here</div>

How to make an absolute positioned div fill the entire document area

I need to have an absolute div that is a child of only body fill the entire document area (window + any scroll area)
-- width: 100% only fills the viewable screen
I prefer a CSS only solution but pure javascript is ok. I tried without success setting:
opaque.style.minHeight = Math.max(document.body.offsetHeight, document.body.scrollHeight);
I made a jsFiddle of the code below. If you scroll down the output, you will see that the opaque div stops at whatever height the output window was when it was rendered.
In case you are wondering... it is to make an opaque overlay of all content in the div behind it (think slideshow). My only other solution is to disable scrolling, but this is problematic.
Thanks for any help.
<div class="page-container"></div>
<div id="opaque"></div>
body {
width:100%;
}
.page-container {
position: relative;
max-width:978px;
width: 100%;
min-height:2500px;
margin:0 auto -50px auto;
border:solid #999;
border-width:2px;
background: lightblue;
}
#opaque {
position: absolute;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
z-index: 100;
background: grey;
filter: alpha(opacity=70);
opacity: 0.7;
}
Can use
#opaque {
position: fixed;
top: 0;
left: 0;
right:0;
bottom:0;
}
remove width:100% from body due to creates horizontal scrollbar
Depending on use case it is often common to add class to body when using such an overlay that sets body overflow to hidden
DEMO
You can put a position: relative on your body so that the body will be used as a reference point by the child element in terms of height (as opposed to the document object).
Using javascript to set one elements height equal to anothers
var o = document.getElementById('opaque');
var p = document.querySelector('.page-container');
o.style.height = window.getComputedStyle(p).getPropertyValue("height");

How to make an interactive sidebar with jQuery and CSS3?

I have asked questions like this and have not really got an answer that really helped me! I know it is probably very easy and i just can't figure it out!
I have been studying jQuery for a few days now and have the basics down but cant create the right function to make this effect happen! Please visit the website below!
There are a few things i would like to know about! The first thing is when you first go to the site everything slides into place (sidebar, footer, etc.) The main concern is the sidebar how when you hover over one of the icons a kind of tool-tip eases appears and eases to the right side.
The next part i would like to know is when you click one of the icons a whole another window pops out. I kind of have an idea of how these both happen but i cant put all the pieces together. Please help me out! I know it cannot be that difficult. Even if you know of any jQuery plugins that can help achieve these results, would be even better!

HTML
<div id="sidemenu">
<div id="regionsContainer">
<div id="regionsUnitedStates"></div>
</div>
</div>
CSS
#sidemenu {
width: 60px;
height: 100%;
min-width: 60px;
height: 100vh;
max-width: 60px;
background-color: #383D3F;
background-size: 100% 100%;
background-attachment: fixed;
margin-top: -8px;
margin-bottom: -8px;
margin-left: -8px;
position: absolute;
}
#regionsContainer {
width: 60px;
height: 481px;
min-height: 481px;
min-width: 60px;
max-width: 60px;
max-height: 481px;
background-color: #383D3F;
position: relative;
top: 25%;
bottom: 25%;
}
#regionsUnitedStates {
width: 60px;
height: 60px;
background-image:url(../_images/_header/regionsUnitedStates.png);
}
#regionsUnitedStates:hover {
background-position:bottom;
}
you can do that using position: absolute like mentioned by fizzix before, and for each of your question with this html example
<div id="sidemenu">
<div id="submenu" class="not-open">
Sub
<div id="submenu-inner">
inner
</div>
</div>
<div id="submenu-item1">
item
</div>
</div>
1 The first thing is when you first go to the site everything slides into place (sidebar, footer, etc.)
This can be achieved with jQuery on document ready, and using setTimeout if you want to further delay it, then add a class to the element, like this
CSS :
#sidemenu {
background: #000;
width: 50px;
height: 100%;
position: absolute;
left: -50px;
transition: left ease-in-out 0.5s;
}
#sidemenu.show {
left: 0;
}
jQuery :
$(function() {
setTimeout(function() { $("#sidemenu").addClass("show") }, 500);
});
2 The main concern is the sidebar how when you hover over one of the icons a kind of tool-tip eases appears and eases to the right side.
This can be achieved with only CSS on hover, what you need is put the floating element inside the element you want to hover, in this example submenu-inner inside submenu, then add some CSS
#submenu {
background: #fff;
height: 50px;
margin: 150px 0 0 0;
text-align: center;
position: relative;
}
#submenu.not-open:hover #submenu-inner {
left: 50px;
opacity: 1;
}
#submenu-inner {
opacity: 0;
position: absolute;
transition: all ease-in-out 0.5s;
top: 0;
left: 250px;
height: 50px;
background: #f00;
}
firstly, the inner element is transparent and positioned more to the right using left, then on hover, set the position right beside the container, by setting the left CSS again to the width of the container
3 The next part i would like to know is when you click one of the icons a whole another window pops out
it's the same with number 1, except this one triggered by onClick event
here's the working example on JSFIDDLE
I dont think any plugin is required.
You can use translate to keep the menu hidden.transform:translate(90%)
Please refer this example:JSFIDDLE
The entire site is using absolute positions. This means that they are positioned on the page with pixel co-ordinates. They then using jQuery animate to move the top and left positions.
I have made a brief example of how to do this HERE. You can edit this to your liking.
If you are interested in seeing what the site was built with, you can see a whole list HERE

Javascript ribbon hidden behind invisible box

So I have two images, one is a half of a ribbon and the second one is a full ribbon with facebook etc links on it. I need to have the first one in the middle of a page, so when you click it it would expand out. I figured i need to use hidden overlay or something but I am totally new at javascript.
Can someone provide an example or help me with this?
I tried to understand what you want and tell me if this is what you meant.
You can wrap the two images in two sepatare divs and then wrap them in a div with position relative.
Then you give to the two divs position absolute.
On the click of the first div you change the second div left position (or the top if you want a vertical effect).
Here is the html with divs only:
<div style="position: relative">
<div id="frontDiv">
aaaaaaaaaaaa
</div>
<div id="backDiv">
bbbbbbbbbbb
</div>
</div>
Here the CSS:
#frontDiv{
height: 20px; width: 45px;
background: red; position: absolute;
z-index: 1; left: 0px; top: 0px;
}
#backDiv{
height: 20px; width: 30px;
background: blue; position: absolute;
z-index: 0; left: 0px; top: 0px;
}
And here the javascript (in jQuery):
$("#frontDiv").click(function(){
$("#backDiv").animate({"left":"45px"}, 300); //{"top":"20px"} for vertical effect
});
At the end you can position the wrapper div wherever you want.

Getting the footer on the bottom of the page

This dreaded problem.
What I currently have
html:
<html>
<body>
<div class="wrapper"></div>
<div class ="footer"></div>
</body>
</html
css:
* {
margin: 0;
}
html, body {
height: auto !important;
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0;
}
.footer
height: 36px;
}
The problem is when i inspect the rendered page with chrome a few problems I see:
1. The html tag has a height associated with it hmmm and its not the entire page height
2. so I have div inside of the wrapper div that extends past the wrapper, body, and html tag?
My best guess is that if i can get the html to the page height I could style the footer to page bottom.
I was considering using javascript to grab the true height in pixels and passing that to height and ditching the percent. Only problem is I still want to know whats going on!
Thanks,
JT
add this css to your wrapper divs
wrapper_div{ overflow:hidden; }
this is a hack to recalculate floated elements inside an element. Otherwise the browser will forget about the floated elements, overflow-hidden does the trick or you can append a clear floated element to the bottom of the wrapper div like so
CSS
clear_float{
clear:both; display:block;
overflow:hidden; visibility:hidden;
width:0px; height:0px;
}
HTML
<div class="wrapperdiv">
/* other HTML elements*/
<div class="clear_float"></div>
</div>
this is assuming that the troublesome div is classed wrapperdiv
on second look this is completely invalid
html, body {
height: auto !important;
height: 100%;
}
.wrapper {
height: auto !important;
height: 100%;
}
you are setting the height twice in one declaration. height: auto !Important will take precedent over height: 100% so you need to decide whether you want your height automatically rendered over explicitly at 100%.
and your missing the opening block in this css declaration
.footer
height: 36px;
}
Just before the closing tag of the wrapper add a div with the class 'clear'
CSS:
.clear { clear: both; }
.footer { margin-top: -36px; }
The problem is that floated elements behave like absolute positioned elements.. They are not taken in account when calculating the height of the wrapper div.
In the end I just made the html body tags set via pixels and not percent. Nothing I tried above satisfied me.
If you want a facebook like fixed footer status bar. Try using the following css:
.footer {
width: 100%;
height: 25px;
position: fixed;
bottom: 0px;
