how to make the scrollbar of the hole page affect only on ConentPlaceHolder , i use style=" overflow:scroll; height: 500px;" but it makes a special scrollbar for Conentplaceholder but i want the main scrollbar to do this effect .
As far as I know, the best way to do it will be to use position:fixed on all your non-scrolling elements, and then just let the page flow normally. This way, the main scrollbar will scroll the content while the rest of the page appears not to move, giving the desired effect.
Here is a jsfiddle of Dereleased's suggestion: http://jsfiddle.net/sQmhY/2/
Note that the padding of the #content div is the same as the heights of the #header and #footer divs.

I have this footer that will not stick to the bottom of the page.
I think the issue is with my HTML and body not spanning the entire site but I just cannot find the exact place to correct this. I know its a big no-no to link to my page but I simply don't know what code to post here.
I cannot set the content to static instead of absolute because then my menu items will start pushing the content divs around when they open.
To fixed position into bottom you can try this code
Html:
<div class="tofix">
<p>Fixed this div into bottom</p>
</div>
Css:
.tofix{
width:300px;
position:fixed;
bottom:0;
}
The problem occurs because of your #content. You just try to change its position as following:
#content{
position : static;
}
Or you just simply remove it because the position is set as static by default.
Remove the position:absolute from your #content.
Also It worked when I first opened the link, please don't change the live code while asking the question.
Is there a way using css and html to control the maximum scrollable height of a page, regardless of the content which is present on the page?
For a concrete, hypothetical example: say the <body> is incredibly simple - a <div> which is 5000px tall. How would you set the scrollable height to be only 2000px?
Thus it would appear that the 2000th pixel is the last pixel on the page. The browser's scroll bar would appear to be at the bottom, not just "stuck" halfway down the page. Am I missing something simple to achieve this behavior? I would prefer pure css/html because it seems like it should be doable, but I would accept js.
You can do something like this
HTML
<div class="outer">
<div class="inner">
<!--your content here-->
</div>
</div>
CSS
.outer {
height:2000px;
overflow:auto;
}
.inner {
height:5000px;
overflow:hidden;
}
You should set the body height to a specific number and set overflow to hidden.
body{
height:2000px;
overflow:hidden;
}
Made an example here
Use max-height or height css properties and overflow:hidden on your container element. It will hide everything that is greater than the height you specify, therefore limiting the scrollbar height.
I should also mention that you can use overflow-y:hidden will achieve the same thing, but will only affect top and bottom edges of an element. See more details here.
html:
<div class="div_fixed"></div>
<div class="other_content">
content goes here
</div>
css:
.div_fixed{
position:fixed;
height:40px;
}
.other_content{
height:200px;
}
The div_fixed will remain fixed at the top position of the page.
But as the page scrolls up, the content of the div other_content will vanish just at the lower edge of the div div_fixed .
In the case of scrolling down the invisible content of other_content will begin to be visible from the lower edge of the div_fixed
How to achieve that ?
EDIT: no scroll bar should appear for any div
Use overflow: hidden to get rid of scrollbars
Is this what you're looking for? http://jsfiddle.net/BCRPa/
I've taken your HTML/CSS and added a bit on a jsFiddle - I think in order to achieve the effect you're looking for, you just need to make your content actually tall enough to be scrollable. At 200px high and one line of text, nothing is going to scroll.
So I made your other_content div taller, and then added a top: 0 to your .div_fixed selector, to keep it stuck to the top of the screen, and a margin-top: 40px to the .other_content div in order to have it start below the floating div.
If you want it to be a navbar-type thing, you can of course add a width: 100% to the .div_fixed.
All of this should transfer into a container div (with position: relative) fairly easily as well if you want, although you may have to re-position the fixed div.
I'm looking for a way I can create a div which will be fixed on the page vertically, so if the user scrolls down, the div stays at the same place on the page. But have it positioned absolutely horizontally, so if the users screen is narrower than my webpage, scrolling to the right or left will not cause the div to move with the screen and, in some cases, remain either half visible at the edge of the screen or off the page completely.
This div must be within a "Position:Relative" Div.
I'm fairly sure there is no way to assign different positions to the varying axis of a div but this is the best way to describe the effect which I am hoping to achieve.
I have this so far, which is basically just a Fixed Div within a Relative Div.
CSS
#container {
position:relative;
width:700px;
height:1000px;
top:50px;
left:50px;
background-color:yellow;
}
#blue-box{
position:fixed;
width:100px;
height:100px;
background-color:blue;
margin-top:20px;
margin-left:400px;
{
HTML
<div id="container">
<div id="blue-box"></div>
</div>
I have also created a jsFiddle to help demonstrate the problem.
This works fine for the vertical, but if you resize your web-browser so that it is narrower than the yellow box (container) and then scroll horizontally, the blue box will move with the page. I'm hoping to stop that from happening.
If there is no way to achieve this through CSS, I'm perfectly happy to use JavaScript as long as it works with all modern browsers and both IE7 and IE8. (Which is why I have added the JavaScript tag)
Can anyone help me out?
With JQuery, use the scrollLeft() property of the document! This would work
$(window).scroll(function(event) {
$("#blue-box").css("margin-left", 400-$(document).scrollLeft());
});

Good luck!
Edit: If you want it to use your preset margin-left instead of a hard-coded "400", use
$(window).scroll(function(event) {
$("#blue-box").css("margin-left", $("#blue-box").css("margin-left")-$(document).scrollLeft());
});
Using vanilla javascript would be something like this:
var bb = document.getElementById('blue-box');
window.addEventListener('scroll',function(event){
bb.style.marginLeft = window.scrollX + 'px';
});
In modern browsers, as of 2020, you should try to use the CSS position:fixed; instead of JavaScript positioning because it is widely supported now.
Here's my solution (tested in Opera and Firefox): http://jsfiddle.net/cCH2Z/2
The trick is to specify right: 0px;, this will position the box 0px from the right border of the window.
I've seen this done in a few sites, an example is artofadambetts.com. The scroll bar on the page scrolls only an element of the page, not the entire page. I looked at the source and havent't been able to figure it out yet. How is this done?
That's pretty nifty. He uses "position:fixed" on most of the divs, and the one that scrolls is the one that doesn't have it.
In fact it is not the scrolling part that is "doing the job", it is the fixed part of the page.
In order to do this, you should use CSS and add position: fixed; property (use it with top, bottom, left and/or right properties) to the elements that you wish not to scroll.
And you should not forget to give them a greater z-index, if you don't there might be some of the scrolling element that can go over your fixed element as you scroll (and you certainly don't want that).
To find out how people do these kinds of things in CSS and/or Javascript the tool Firebug is just outstanding:
Firebug addon for Firefox
It should be noted that without further hacks position fixed does not work for IE6, which is still managing to hold on to 15-30% of the market, depending on your site.
You can use fixed positioning or absolute positioning to tie various elements to fixed positions on the page. Alternatively you can specify a fixed size element (such as a DIV) and use overflow: scroll to force the scrollbars on that.
As already mentioned, getting everything to work in Internet Explorer AND Firefox/Opera/Safari requires judicious use of hacks.
This can be done in CSS using the "position:absolute;" clause
Here is an example template:
http://www.demusdesign.com/bipolar/index.html
From http://www.demusdesign.com/
The browser is scrolling the page, its just that part of it is fixed in position.
This is done by using the "position: fixed" CSS property on the part that you wish not to scroll.
They've set the side and top elements to have fixed positions via CSS (see line 94 of their style.css file). This holds them in the viewport while the rest scrolls.
Try this for scrolling a particular part of web page......

For a div, you can add in the cSS
overflow: auto
For example,
<div style="overflow:auto; height: 500px">Some really long text</div>
Edit: After looking at the site you posted, you probably don't want this. What he does in his website is make the layout as fixed (position: fixed) and assigns it a higher z-index than the text, which is lower z-index.
For example:
<div class="highz"> //Put random stuff here. it'll be fixed </div>
<div class="lowz"> Put stuff here you want to scroll and position it.</div>
with css file
div.highz {position: fixed; z-index: 2;}
div.lowz {position: fixed; z-index: 1;}
To put scroll bars on an element such as a div:
<div style="overflow-x: auto; overflow-y: auto;>the content</div>
If you only want a horizontal or vertical scroll bar, only use whichever of overflow-x and overflow-y you need.
