Problems with layout css and javascript - html

I have the following layout:
On the left side I have a menu and big gray part on the right side is the body content. The problem is on the left menu I have a bunch of buttons. I want this menu to be fixed position and body scrollable. I Have the following css:
#menu {
position: fixed;
}
#content {
position: inherit;
margin-left:300px;
}
The problem is that on the red part of my menu all button unavailable, I can't click on it. looks like body overrides the menu.
Any ideas what the problem might be?
Thanks

Including the html would give a better sense of the stacking order and likely yield a better answer. Given what you've provided, this should fix:
#menu {
position: fixed;
z-index: 1;
}

In order to fix it to the top and not scroll, you don't use position: fixed;. You need to use position: absolute;. If you don't want it at the very top, then you use position: relative; and place it inside an element.
Then, in order to scroll, you use position: fixed;.
When you use position: fixed, it places the element fixed within the visible page.
However, when you use position: absolute, what this does is put it on an absolute position on the page regardless of scroll. For example, if you added the css top:0; then it would be 0 pixes from the absolute top of page, and if you scroll down it will disappear from view because it is all the way at the top of the actual page, not just the top of the visible page.
I understand it seems a bit counter-intuitive to you. However, you can see it working in the jsbin below.

Off screen absolute positioned Div causing horizontal scrolling

EDIT/UPDATE: 7th June 2019
I've determined this is a bug in Safari, as the CSS works perfectly in all other browser. For anyone who finds this, if you're creating a sliding menu (which slides offscreen to the right of the viewport), as of Safari 12.1.1, adding overflow-x to the body tag will not work (it does work on Chrome, Firefox etc) - this means that when your menu div is positioned offscreen to the right, the user can scroll horizontally and see the menu.
I've found a (sort of) workaround is to give the parent container of the menu dive a position:fixed attribute - this obviously only works if you intend for your header to be fixed.
Original Question
I'm building a simple header with a menu that slides from right to left when the menu button is pressed. However, when I position the menu div offscreen (left: 100%), on Safari, I can scroll horizontally right to see the menu div. (No scroll bars appear, but I can scroll right via the Mouse)
If I set overflow-x:hidden on the header, then it hides the offscreen div, but also won't show it if you set the left:0 (ie. overflow-x seems to be hiding x and y directions).
Even more perplexing, if I change the header to position:fixed, then it works and you can't scroll right to see the offscreen menu div.
html, body {
margin: 0;
padding: 0;
width: 100%;
height: 100%;
}
.header {
width: 100%;
padding: 10px;
background: #CCC;
position: relative;
}
.slideMenu {
position: absolute;
top: 100%;
left: 100%;
width: 100%;
padding: 10px;
background: #666;
}
<div class="header">
Header ---> Scroll to Right
<div class="slideMenu">
Menu is visible offscreen- :(
</div>
</div>
Here's an example of the problem: https://jsfiddle.net/ar7qyfgt/
I ran into a similar issue with Safari. Solution that appears to be working is to apply overflow-x: hidden; to the html AND body tags.
Adding to body resolved issue in all browsers expect Safari. Applying it to both seems to do the trick with Safari while still supporting the other browsers.
I have the same issue in my Safari(Version 12.1.1) when I set my div to position: absolute and right: -15rem;
To fix it, I added a to include all elements within and have the CSS like this:
.wrapper {
position: relative;
overflow-x: hidden;
}
Hope this help.
What you currently have works, you just need to set overflow-x:hidden on the body instead of the .header
What are you trying to accomplish? This?:

How to eliminate whitespace when scrolling [fixed sidebar]

Let me first try to illustrate the problem
I have a webpage which contains a header and a sidenav. The sidenav is fixed in css, since I don't its content to move when scrolling.
When the page isn't scrolled down it works as intended, somewhat like this
However when I scroll i don't want whitespace on top of the sidenav. Currently when I scroll down the page, it looks somewhat like this
The intended behavior should be something like this
How do I go about this in css? Do I mess with the z-index of the elements? so the sidenav is behind the header when the page isn't scrolled? Or do I dynamically add to the sidenav's size when scrolling?
And how would either of these options be done in css?
As I understand, you have to set z-index of the header higher than the sidenav
Stack Snippet
.header {
height: 100px;
background: #000000;
position: relative;
z-index:999;

css for modal - how to position it above page yet scrollable in window

Here is the html:
<body>
<div class="ngdialog">
<div class="ngdialog-overlay></div>
<div class="ngdialog-content>
...modal content
</div.
</div>
<body>
The ngdialog div is, as you can guess, an modal (z-index: 10000).
My goal is, by applying some comination of styles (position, float etc.) to the elements to make it so that:
a) When the modal is displayed, have the overlay (grey and opacity; 0.5) cover all other elements in the page.
b) If the modal content is longer than the page, I would like the user to be able to use the main scroll bar to see the bottom/top of the modal. In other words, if the rest of the page is only 100px but the modal is 200px, I would like the scoll bar to allow the user to scroll that extra 100px.
The issue I am having is that when I position ngdialog as absolute, the window won't allow me to scroll to see the rest of the modal (as the absolute element is no longer in the standard element flow).
If I try to use fixed positioning, there is no scroll bar. If I use relative positioning, the other page elements (which the overlay is above) get moved around.
I have tried (what feels like) every combination of absolute, relative, fixed, static, float on all of these elements and I can't get the behavior I am seeking.
Keep in mind that body is position: relative (this can be changed if need be).
Thanks in advance, appreciate all comments.
Edit: Sorry, I had to go to sleep there, here is a fiddle:
https://jsfiddle.net/vpgoy756/1/
WIthout changing your HTML structure, this is what you'd need to do:
* {
/* This was to save typing */
margin: 0;
padding: 0;
}
html {
width: 100%;
height: 100%;
}
body {
position: relative;
width: 100%;
min-height: 100%;
}
.ngdialog {
z-index: 10000;
text-align: center;
overflow: hidden;
}
.ngdialog-overlay {
position: absolute;
width: 100%;
height: 100%;
z-index: 9999;
background: rgba(0,0,0, .4);
}
.ngdialog-content {
position: absolute;
z-index: 10000;
width: 100%;
height: 100%;
max-height: 100%;
overflow: auto;
}
.panel {
margin-top: 50px;
margin-left: 10%;
margin-right: 10%;
min-height: 500px;
z-index: 10000;
}
.reg-page-block {
width: 200px;
height: 200px;
display: inline-block;
background-color: #0f0;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css" rel="stylesheet"/>
<!-- ^ from your provided fiddle -->
<body>
<div class="ngdialog">
<div class="ngdialog-overlay"></div>
<div class="ngdialog-content">
<div class="panel panel-primary">
<div class="panel-heading">modal</div>
<div class="panel-body">content</div>
</div>
</div>
</div>
<div class="reg-page-block">Regular Page</div>
</body>
Be aware that if both the dialog and content are taller than the viewport, you will get double scrollbars - this may not be desirable but you specifically asked for the dialog to scroll separately from the content.
Try some of this CSS and see if it does the trick. It's hard to provide an exact solution without seeing your current CSS code, but maybe this will work.
Use this HTML structure instead:
<div class="ngdialog-overlay">
<div class="ngdialog-content">CONTENT HERE</div>
</div>
And this CSS code:
.ngdialog-overlay {
display:block;
width:100%;
height:100%;
background:#333333;
background:rgba(0,0,0,0.8);
z-index:10000;
position:fixed;
top:0;
left:0;
overflow: scroll;
}
.ngdialog-content{
text-align: center;
width:100%;
height:100%;
padding-top:30px;
padding-bottom:30px;
/* Optional if you want content vertically centered */
display:table-cell;
vertical-align: middle;
}
The trick is overflow:scroll; and height:100%; - because we have a set height, if the contents become any taller than that they will overflow and scroll. But in this case, when the user tries to scroll it will actually be scrolling the .ngdialog-overlay element and not the window itself.

In CSS file Add below lines
.modal-dialog {
transform: translateY(50%)!important;
}
You can change 50% to any other value which will solve problem in your Browser
It worked for me

CSS: Banner&Menu postions

Short sketch of the situation: I'm making a website (obviously :)) and so I've got my header, then my banner and below the banner i've got my menu bar. However, the banner overlaps my header a bit (that's the intention ;)) and now I want to add the menu bar directly below the banner.
Here's my CSS code:
.header_container{
background-color: #e5e5e5;
height: 200px;
overflow: hidden;
}
.banner {
position: relative;
top: -90px;
background: url(../images/banner.png) no-repeat top center;
height: 210px;
}
.menu {
background: url(../images/menubalk.png) no-repeat top center;
}
The menubar is at the position where i should be if the banner would not have an overlap.
I have just figured something small out, which would probably fix my entire problem. If I were to make my header a box, and then my main content a box (which holds the banner, content and footer) and make all the different things, like the banner children from that box? wouldn't that fix my entire problem while I use the inherit or whatever function?
Thank you in advance!
Kind regards,
David
One way of doing this has been suggested, use relative positioning for the menu element.
For example:
<div class="header_container">
Le Header Container
</div>
<div class="banner">
Le Banner
</div>
<div class="menu">
Le Menu
</div>
and the CSS would look like:
.header_container{
background-color: #e5e5e5;
height: 200px;
overflow: hidden;
}
.banner {
background-color: yellow;
position: relative;
top: -90px;
height: 210px;
}
.menu {
background-color: red;
position: relative;
top: -90px;
height: 50px;
}
As a start, here is a fiddle: http://jsfiddle.net/audetwebdesign/9gvTG/
Alternative Method
You can achieve a similar effect by using a negative margin:
.header_container{
background-color: #e5e5e5;
height: 200px;
overflow: hidden;
margin-bottom: -90px; // only need to adjust this property
}
.banner {
background-color: yellow;
position: relative;
height: 210px;
}
.menu {
background-color: red;
position: relative;
height: 50px;
}
The advantage of this approach is that the positioning of the subsequent elements do not need adjusting if you change the header and need to modify the degree of overlap by the banner element.
It is good to be aware of both approaches.
One solution in your case would be to position your menu absolute at bottom:-120px. It's not the most elegant one but it should work.
You should assign a relative position to your menu as well. With same top value as the banner
.menu {
....
....
position: relative;
top:-90px;
}
The space you see is because the menu, in normal document flow, is positioned just below the place the banner is located. (which is shifted 90px up from its real position)
A fiddle here
Instead of your images I used background color
You can place the menu just at the bottom of your banner or where ever you need.
Then remember that element that follows the menu will see the menu in his real position . In this case 90px below.Many solutions to wrap all this issue so wont affect the rest of the page elements.

How to create a scrolling or static sidebar menu

I am looking for programming help on how to do a sidebar menu like the one shown at this URL:
Nettuts Website Link
I would like my sidebar to function just like the sidebar on the website, with my own look and feel applied to it. I would like the sidebar to scroll with the page fixed at its own location just as it functions on Nettuts website. How would I program this?
It is a div with the css statement position: fixed; in the css class declaration.
Give any div in your html this CSS styling and you should see it working.
position: fixed;
height: 132px;
left: 0;
top: 185px;
width: 24px;
that side bar is nothing more than a div with a fixed position.
<style>
.sidebar {
width: 45px;
height: 90px;
position: fixed;
left: 0px;
top: 300px;
border: 1px solid black;
}
</style>
<div class='sidebar'>I'm a sidebar</div>
http://jsfiddle.net/p8dFM/
At that point you add elements to the sidebar with whatever functionality you want.
Create a style class like..
.class{
overflow:auto;
height:100%;
width:354px;
top:185px;
}
