You can see my layout prototype on Design Prototype.
I have two : Header and Container. Header area must be placed above the container.
Header has two child elements: Logo DIV and Logo-Title DIV. Their positions being rated to parent [Header DIV].
So, I set position of header to relative and children (Logo and Logo-Title) to absolute.
But after it, Container didn't place under header area!
When i remove absolute position from Logo DIV and Logo-TITLE DIV, The Container is OK! but i can align logo and logo-title from parent(Header).
Why? Container isn't child of Header!
How can fix it?
Thanks.

The single tag closure used on your logo doesn't work on div element so I changed it like this
<div id="logo"></div>
Colored your container to red temporary, so one can see that it renders correct now
#charset "utf-8";

margin: 0 auto;

<div id="logo-title">Logo-Title</div>

Your logo div has not correct syntax , closed always div with close div tag like this <div id="logo"></div>

when I scroll down on my page, my container overlap the header, but I want my header to overlap the container, so I made my header on a fixed position, but it does not work
here is my html code:
<html>
<head>
<meta charset="UTF-8" />
<script src="script.js"></script>
<link rel="stylesheet" type="text/css" href="styles.css" />
</head>
<body>
<div class="page">
<header class="leheader">
<div id="bloc1"></div>
<img src="https://i.imgur.com/dm6H7GV.png">
<div id="bloc2"></div>
</header>
<main class="container"></main>
</div>
</body>
</html>
and here is my css code:
body,
html,
.page {
background: #666666;
width: 99%;
height: 100%;
}
.leheader {
display: flex;
width: 99%;
position: fixed;
flex: 1 100%;
height: calc(100%-50px);
}
#bloc1 {
margin-left: 1px;
margin-top: 0.5px;
height: 50px;
width: 90px;
background: #cccccc;
border-radius: 10px 0 0 0;
}
#bloc2 {
background: #467491;
margin-top: 4px;
width: 93%;
height: 37px;
}
.container {
position: absolute;
top: 57px;
left: 9px;
background: #cccccc;
width: 99%;
height: calc(100% - 33px);
}
where is the problem ?
Try adding the z-index property to the header.
like this....
z-index: 2
In CSS to make something Fixed position you also need to give it a z-index (which is its position on z-axis). Read more about Z-Index here. Apart from it you also have to give it a position in terms of top, left, bottom and left to tell it where it has to fixed.
.leheader {
display: flex;
width: 99%;
position: fixed;
top:0;
left:0;
z-index:2;
flex: 1 100%;
height: calc(100%-50px);
}
I would like to have an element looking like a navbar at the top of my website:
It should be fixed, like a navbar. However, as soon as the user scrolls down, it should disappear under the rest of the content:
I tried something like that, where the #title element is the "navbar":
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<div id="title" class="center-align">
<h1>Title</h1>
<h2>Subtitle</h2>
</div>
<div id="showcase" class="center-align">
</div>
</body>
<style>
#title {
position: fixed;
width: 100%;
height: 50vh;
z-index: -1;
}
#showcase {
margin-top: 50vh;
height: 75vh;
background-color: #212121;
}
</style>
</html>
However this is not working, the #title seems to be also affected by the 50vh margin-top (you can see it by setting its z-index to 1 instead of -1).
No need to use z-index
By default sibling are stacking by the order from bottom to top so the 1st child will at the bottom, the last child at the top. See example here:
Example of sibling z-index:
.div1 {
width: 100px;
height: 100px;
background: red;
}
.div2 {
margin-top: -50px;
margin-left: 50px;
width: 100px;
height: 100px;
background: green;
}
.div3 {
margin-top: -50px;
margin-left: 100px;
width: 100px;
height: 100px;
background: aqua;
}
<div class="div1">
div1
</div>
<div class="div2">
div2
</div>
<div class="div3">
div3
</div>
Solution to your problem:
#title {
width: 100%;
height: 100px;
text-align: center;
position: fixed;
top: 0;
}
#showcase {
margin-top: 120px;
height: 90vh;
background: black;
}
<div id="title">
<h1>Title</h1>
<h2>Subtitle</h2>
</div>
<div id="showcase">
</div>
Try change your style with the following css . I made some changes for test purpose.
#title {
position: fixed;
width: 100%;
height: 50vh;
z-index: -1;
background: red ;
top:0;
}
#showcase {
margin-top: 50vh;
height: 275vh;
background-color: #212121;
}
Hope it helps
Here's an example using a fixed navabr and a normal div for the content having a margin-top:
body {
margin:0;
height:100%;
}
.navbar {
width: 100%;
height: 50px;
line-height: 50px;
position: fixed;
background-color: lightblue;
z-index:-1;
}
.content {
width: 100%;
float: left;
height: 1000px;
margin-top: 50px;
background-color: red;
}
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<div class="navbar">
Navbar
</div>
<div class="content">
Content
</div>
</body>
</html>
Add top: 0 to the title id. Like:
#title {
position: fixed;
width: 100%;
height: 50vh;
z-index: 1;
top: 0;
}
The html page below contains a footer (position: fixed) and a "Sheet" (position: absolute).
My problem: How to prevent the bottom end of the Sheet to be hidden underneath the footer when I scroll down?
All my attempts with padding and margin failed ... (Please only html/css solutions.)
CSS
body {
background: green; }
.Background {
top: 0px;
right: 0px; }
.Footer {
position: fixed;
bottom: 0;
left: 0px;
height: 30px;
width: 100%;
background: orange;
padding: 0 10px 0 10px; }
.Sheet {
position: absolute;
top: 100px;
left: 25px;
border-style: solid;
border-width: 2px;
padding: 20px;
background: red; }
HTML
<body>
<div class="Background">
Background</div>
<div class="Sheet">
<div style="line-height: 200px">
Sheet<br>
Sheet<br>
Sheet<br></div>
Sheet<br>
Sheet</div>
<div class="Footer">
Footer </div>
</body>
Give margin-bottom to sheet which is equal or grater than footer fix height;
.Sheet {
margin-bottom: 35px; // equal or greater than footer height
}
Update
if you want to bring in front of all then add z-index property.
.Sheet {
margin-bottom: 35px; // equal or greater than footer height
z-index: 999; // use suitable maximum to bring in front all
}
The problem as I see it is the absolute position of the sheet, as absolute positions do not affect the height of the surroundung Element (in your case the body).
If possible try position: relative;. Then your margin can be counted in.
See https://jsfiddle.net/y3mg5zvb/
If it has to be absolute for any reason, you need a surrounding div with relative or static positioning that sets the height of the body.

This helps you?
Just don't use absolute position on .Sheet - there's no reason for it. Replace top and left with margin-top and margin-left and use a margin-bottom at least as high as the footer.
.Sheet {
margin-top: 100px;
margin-left: 25px;
margin-bottom: 30px; /* whatever value */
border-style: solid;
border-width: 2px;
padding: 20px;
background: red;
}
I think this is a perfect solution!!!

try playing around with z-index and some
I have a DIV aligned centrally via CSS. But the problem is: when I want to align the second DIV the middle, then this DIV is distorted or left aligned. It is important that a DIV with "position absolute" and must be scrollable. And an other DIV with "position fixed" includes fixed and must remain always on top. What am I doing wrong? See a image: http://home.arcor.de/freedownload/wrong.jpg Here is code of HTML:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//DE"
"http://www.w3.org/TR/html4/loose.dtd">
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//DE"

</div>
<div id="navigation"></div>

padding: 0px;
}
a {

font-family: Verdana;

font-weight: bold;
text-decoration: none;
}
a:hover {

text-decoration: none;
}
#top_fixed_content {

left: 50%;
width: 1170px;
margin-left: -585px;
z-index: 1000;
}
#topheader {
background-color: #fbfbfb;
height: 103px;
}
#topheader_logo {
position: absolute;
top: 33px;
left: 10px;
background-image:url(logo.png);
background-repeat: no-repeat;

height: 40px;
display: block;
}
#navigation {
background-image:url(navigationbg.png);
background-repeat: repeat-x;
background-color: #48b1f8;
height: 34px;
}
#main_content {
position: absolute;
background-color: #fbfbfb;
width: 1170px;
margin-left: -585px;
}
I hope someone can help me and find the solution. It would be fully appreciated.
You forgot the close #main_content, replace
<div id="main_content">
<div id="main">noisy lines...</div>
<div>
with
<div id="main_content">
<div id="main">noisy lines...</div>
</div>
And add left: 50% to the CSS of #main_content
I can't get the img element to move to the left hand side. The left: 0px attribute isn't doing anything. In fact, I can't seem to move anything inside the #top div to move.
The img tag is inside top. I omitted rest of the webpage but I hope this is enough.
HTML code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div id="topBorder"> </div>
<div id="top">
<img src="logo.png" style="width:50%; height: 20%; left: 2em"/>
</div>
</body>
</html>
CSS code:
body {
max-width: 60em;
margin: auto;
position: relative;
}
div {
border: solid;
text-align: center;
margin-top: 1em;
margin-bottom: 1em;
}
#topBorder {
background-color:#255FAA;
height: .7em;
width: 100%;
border: transparent;
}
#top {
background-color: white;
border: transparent;
height: 13%;
width: 100%;
font-family: Georgia, Palatino Linotype;
}
#top img{
border: solid black;
position: relative;
left: 0px;
}
It looks like the text-align:center from your div element is the problem. Try overriding that in #top and I think it will start behaving as you expect. See this fiddle:
http://jsfiddle.net/3KyrW/
Your #top should have positive: relative, then your #top img should have position: absolute ... that will move the image around in your header.
I am not 100% sure about what how are trying to position. But adding a display: block; and a float: left; to #top img seems to float the image to the left. The left: 0px; is not needed when using position: relative; so I removed it. Also added a position: relative; to the #top <div>.
Also you seem to have inline styles in your <img> tag? That seems off.
<img src="logo.png" style="width:50%; height: 20%; left: 2em"/>
So I took that out & added it to the CSS as well. New <img> tag looks like this:
Revised CSS is here:
#top {
position: relative;
background-color: white;
border: transparent;
height: 13%;
width: 100%;
font-family: Georgia, Palatino Linotype;
}
#top img{
border: solid black;
position: relative;
display: block;
float: left;
width: 50%;
height: 20%;
left: 2em;
}
