css fixed div moves on first tap on ipad - css

I have the following CSS rule for div element in my webpage
#menudiv {
position: fixed;
height: 100%;
margin-left: 5px;
width: 150px;
background: transparent;
z-index:3;
min-height: 680px;
}
This is a menu on the left on my page, and it's fixed positioned. It works well on normal PC displays, while on iPad there is an issue.
When I load the page and I touch the screen with the finger scrolling down, the #menudiv moves together the rest of the page. When I release the finger, the #menudiv returns to its fixed position and then I can scroll up and down the page and it's no longer moves. What am I doing wrong here?

Try to use left property. Also if possible then use top, right, bottom also(as its fixed div)
#menudiv {
position: fixed;
height: 100%;
left: 5px;
width: 150px;
background: transparent;
border: 1px solid transparent;
z-index:3;
min-height: 680px;
}

border-radius shows slight color from parent div background in corners

I have an issue where you can clearly see the parent in the top right and top left corners of the child.
I have tried with using overflow: hidden; on parent as well as using border-radius on the child.
The issue is a bit hard to explain but you can clearly see the issue on the fiddle.
https://jsfiddle.net/2Lccaf0u/
edit: Here is an image showing the issue as well (using chrome)
An easy fix would be to make the outer element have a large radius than the inner for only the top portion
body {
background: #000;
}
.outer, .outer2 {
width: 200px;
height: 100px;
border-radius: 15px 15px 5px 5px;
background: #fff;
margin-bottom: 20px;
}
.inner, .inner2 {
background: #111;
width: 100%;
height: 50px;
border-radius: 5px;
}
Edit: It's happening because that is how the browser renders it. Not all browsers will produce the same result.

Why is the CSS z-index being ignored in position relative using background cover image?

Overview: I have a CSS3 pure navigation system on top of my page. I have a footer/copyright on bottom.
In the middle, I want a background image (parchment) cover, then on top of that parchment, I want a white layer for text with a left column and a right column. I can't seem to make it work using the relative position as my z-index doesn't seem to be working. If I put position "fixed", I can't use the right browser scroll anymore to go down. If I use position "absolute", then the background is right and the content on top is ok, but my navigation footer disappears. If I use position "relative", my navigation system is fine but the background doesn't show up anymore. It is ignoring the z-index....
The weird thing is I am using expression web 4 and it looks correct there...it just doesn't look correct on the web.
This is my site html to reproduce what I am seeing.
<!-- #BeginEditable "content" -->
<div id="page_content_back">
<div id="column_left">
<h1>About</h1>
<p>We are the best-Trust us</p>
</div>
<div id="column_right">
<h4>CONTACTS</h4>
</div>
</div>
<!-- #EndEditable -->
This is my css
#page_content_back {
position: relative;
background-image:url('../images/grayparchment_back.jpg');
background-size: cover;
z-index: 1;
width: 100%;
margin: auto;
padding: 0;
border-top-width: 1px;
border-top-style: solid;
border-top-color: #CCAA77;
}
#column_left {
position: relative;
margin: 0 50px;
padding: 0 2%;
z-index: 2;
top: 0px;
background-color: #fff;
float: left;
width: 65%;
height: 100%;
color: #393939;
}
#column_right {
position: absolute;
z-index: 3;
float: right;
right: 50px;
top: 370px;
width: 20%;
height: 100%;
margin: 0;
padding: 10px;
background-color: #fff;
}
Okay, the problem is your div#column_left. It has a float: left property. Floating an element takes it out of the flow, so there's nothing within the div#page_content_back to give it any height. Remove that float: left property from the inner div and you'll see the image appear behind it. From there, you can add other elements after that nested div and the image will expand to encapsulate the new element. That said, if you use float or position: absolute, you're removing the element from the flow and that background image won't respond to its presence as a result.

Using CSS to offset the start of a background

I am attempting to make a sidebar for a tumblr page have a curved header and the rest of the sidebar be squared with 100% height so it flows off the "page" with no visible footer. I have layered backgrounds and as you might expect the square background with current coding is going to show at the top of the curve removing the transparent affect I want at the top.
This is the live preview.
Here is the coding used for those side bars:
#left, #right {
background-image: url('http://static.tumblr.com/gxcukg0/VOFn4jkk6/bg-sidehead.png'),
url('http://static.tumblr.com/gxcukg0/6SUn4jkk3/bg-side.png');
background-repeat: no-repeat, repeat-y;
background-color: #b8a6a5;
position: absolute;
min-height: 100%;
top: 0px;
width: 345px; }
Is there a way of accomplishing my goal without making a separate div for the top of each side?
To get this to work, you need to use the :before selector:
#left:before, #right:before{
height: 100px;
width: 345px;
background-image: url('http://static.tumblr.com/gxcukg0/VOFn4jkk6/bg-sidehead.png');
position: absolute;
top: -100px;
content: " ";
}
#left, #right {
background-image: url('http://static.tumblr.com/gxcukg0/6SUn4jkk3/bg-side.png');
background-repeat: repeat-y;
position: absolute;
min-height: 100%;
top: 100px;
width: 345px;
}
Note that I've bumped down the main divs with top: 100px;, bumped up the :before part with top: -100px;, and moved the header background image to the :before.
Oki doki the best way for you to do this would be to use the css style background-position.
For example
img {
background-position :-10px 0px;
}
The above with offset the image by - 10px to the left and 0px to the top.
I hope that helps!

CSS - Position a "normal" div below a div that uses "position: absolute"?

I have a background that covers the entire screen. Black line is end of viewport.
Main-div is just a container (dark blue) using position absolute.
Top-div (yellow) also using position absolute.
Middle-div (red) also using positon absolute.
Why? Well I want the Middle-div (red) to completely cover the screen vertically. Also only half should be visible - needs to scroll to see it.
Everything works fine, but how can I position the Footer-div (yellow) below the Middle-div (red)?
CSS code for Yellow Footer:
#footy
{
width: 100%;
height: 100px;
position: absolute;
bottom: 0px;
border: 1px solid yellow;
text-align: center;
margin-left: auto;
margin-right: auto;
font-size: 12px;
}
Right now it sits on the bottom, leaving too much gap above. Problem it must work on different resolutions. Setting bottom: 100px; will only work on this resolution....
Image:
You cannot position elements relative to other absolutely positioned elements unless they are children of said elements, or both children of the same element when you know the position and size of both elements.
If you make the footer a child of the middle div, you can position it absolutely within:
#footy
{
width: 100%;
height: 100px;
position: absolute;
bottom: -100px;
border: 4px solid yellow;
text-align: center;
margin-left: auto;
margin-right: auto;
font-size: 12px;
}
I don't know all of your other CSS/HTML, but I guessed in a fiddle here, with some exaggeration of borders, etc for visual reference:
http://jsfiddle.net/jtbowden/NuG7T/
You can also create a wrapper around middle and footy:

How to get an offset border round the visible part of the browser window

I've got a set up similar to this: http://codepen.io/anon/pen/iAJnx where the main content is rather long. What I want to do is to put a border round the visible part of the screen as in this screenshot: http://i.imgur.com/ENtLau4.png
What I want to do is to create 4 divs that are positioned at the edges of the screen, but I'm struggling both with the positioning and giving the divs height and width without content. Does anyone have an idea about this?
Note: I've already tried using an overlay, but it makes the content non-clickable.
Try this:
HTML:
<div class="border-box"></div>
CSS:
body { position: relative; }
.border-box {
border: 5px solid blue;
box-shadow: 0 0 100px 100px #fff;
position: fixed;
pointer-events: none;
bottom: 10px;
left: 10px;
right: 10px;
top: 10px;
}
How it works:
I absolutely positioned an overlay with borders, that will stick the edges of the screen by using top, bottom, left, right definitions. To make the content below selectable, you set pointer-events: none; on the overlay.
Example: http://codepen.io/anon/pen/BxJbh
If you want to achieve the same results without adding additional HTML markup, you can use the :before sudo selector to prepend a block to the body. Simply add this CSS and it will produce the same results:
body:before {
border: 5px solid blue;
box-shadow: 0 0 100px 100px #fff;
display: block;
content: '';
position: fixed;
pointer-events: none;
bottom: 10px;
left: 10px;
right: 10px;
top: 10px;
}
Example: http://codepen.io/anon/pen/BDhql
you have to set in your content id (#content)
border:4px solid blue;
min-width:700px; //change accordingly.
min-height:1600px //change accordingly
The above code will fix the problem of border as well as the height & width you want to set without having any content.
