How can I get a fixed Header with a fixed Sidebar and a Content Div?
What i did so far:
body {
margin:0;
}
.header {
width: 100%;
background: #303030;
background-repeat: repeat;
background-size: 38px 133px;
height: 40px;
background-position: 0px 39px;
box-shadow: 0px 1px 5px;
position: fixed;
z-index: 1000;
}
.sidebar {
z-index: 100;
position: fixed;
height: 100%;
width: 200px;
background: #303030;
}
.content {
padding: 10px;
width: 810px;
margin: auto;
min-height: 30px;
box-shadow: 0px 1px 5px;
background-color: rgba(255,255,255,0.7);
margin-left: 20%;
}
<div class="header"></div>
<div class="sidebar"></div>
<div class="content"></div>
But at the moment it's not stable and a bit weird. Means for example that the Content Div is floating under my sidebar and else.
Does someone know a better and more effective was to solve this?
I Think it will help you, For u'r understanding i have added red border for content div. Only I changed the CSS.
.content {
position: fixed;
top: 41px;
bottom: 0px;
left: 200px;
border: 2px solid red;
right: 0px;
}
body {
margin:0;
}
.header {
width: 100%;
background: #303030;
background-repeat: repeat;
background-size: 38px 133px;
height: 40px;
background-position: 0px 39px;
box-shadow: 0px 1px 5px;
position: fixed;
z-index: 1000;
}
.sidebar {
z-index: 100;
position: fixed;
height: 100%;
width: 200px;
background: #303030;
}
.content {
position: fixed;
top: 41px;
bottom: 0px;
left: 200px;
border: 2px solid red;
right: 0px;
}
<div class="header"></div>
<div class="sidebar"></div>
<div class="content"></div>
There are minor changes in your CSS like:
.content {
padding: 10px;
width: 810px;
min-height: 30px;
box-shadow: 0px 1px 5px;
background-color: rgba(255,255,255,0.7);
margin-left: 200px;
margin-top: 40px;
}
.header{top:0}
This will do the trick. If not please comment.

I'm trying to adapt the images from the buttons (#but2, #but1) to their full height possible (in the div) and their corresponding width according to their height (width: auto).
I've tried with this code for the images from the buttons:
#but1 img, #but2 img{
height: 100%;
width: auto;
}
But I can't get the output I want. I share an image showing what's the output of that code and what's the output I want.
Thanks a lot for your help!
#but1 {
margin-left: auto;
margin-right: 5px;
background-color: transparent;

}
#but2 {
margin-left: 5px;
margin-right: auto;
background-color: transparent;
border: 0;
}
#but1 img,
#but2 img {
width: 100%;
height: auto;
}
.button-container {
background-color: #fff;

margin-left: auto;
margin-right: auto;

Try using display: flex; for the button and try to resize the images with pixels like width: 20px; and height: auto; or verse versa, it should fix it.
Here is my idea of doing that: https://jsfiddle.net/L1ma5qrc/86/
*{
margin: 0;
padding: 0;
}
body{
padding: 20px
}
#but1 {
/* margin-right: 5px; */
/* background-color: transparent; */
border: 0;
background-color: #fff;
width: 50%;
height: 50px;
border-radius: 125px;
border: 1px solid lightgray;
box-shadow: 0px 0px 10px 0px rgba(0, 0, 0, 0.2);
}
#but1:before {
content: "";
display: block;
background: url("https://cdn-icons-png.flaticon.com/128/1078/1078599.png") no-repeat;
background-size: 50%;
background-position: center right;
height: 50px;
width: 50px;
margin-right: 16px;
margin-left: auto;

I think I'd look at applying the images as backgrounds. It cleans up the markup quite a bit and makes positioning easier.
Other tips:
Don't use floats for alignment. They're an outdated layout technique and have very few appropriate uses anymore.
Avoid absolute positioning when possible. It can also be troublesome.
Floats don't work with absolute positioning. Use one or the other if you must.
Rely less on IDs in your CSS. Ideally everything is class-based so it's reusable.
Consider not removing outlines. They're important for accessibility.
Avoid using label elements other than with form inputs. That would be nonstandard and also a possible accessibility issue.

background-color: #fff;
width: 50%;

How wide is the default `<body>` margin?
(4 answers)
Closed 5 years ago.
I am making a common header and footer which will be used throughout in all the HTML pages. My page has a white header and white footer and the body is grey colored. Now, my work demands to achieve as below:
What I achieved so far is as below:
I don't know why I am getting these white strips in the sides of the body tag. Please suggest, my code is as below.
main {
background-color: lightgrey;
padding: 50px;
}
header {
background-color: white;
width: 100%;
height: 50px;
}
.content-section {
background-color: lightgrey;
width: 100%;
}
.logo {
height: 20px;
margin: 15px 5px;
width: 116px;
}
.open-card-BG {
font-weight: 300;
margin: 0 auto;
width: 65%;
padding: 20px 40px;
object-fit: contain;
max-width: 325px;
min-height: 200px;
border-radius: 5px;
display: table;
background-color: white;
position: relative;
box-shadow: 0 1px 3px 0 rgba(0, 0, 0, 0.2);
}
.open-card-BG::after {
content: '';
position: absolute;
top: 30px;
left: 100%;
width: 30px;
height: 30px;
background: url(../secure.svg) center no-repeat;
background-size: contain;
}
<header>
<img class="logo" src="logo.gif" />
</header>
<main>
<div class="open-card-BG">main content</div>
</main>
<footer>
I am footer
</footer>
That is because of the default (user agent stylesheet) margin applied by the browser on the body tag - see how the white stripes vanish when I set margin: 0 for body.
Demo below:
body {
margin: 0;
}
main {
background-color: lightgrey;
padding: 50px;
}
header {
background-color: white;
width: 100%;
height: 50px;
}
.content-section {
background-color: lightgrey;
width: 100%;
}
.logo {
height: 20px;
margin: 15px 5px;
width: 116px;
}
.open-card-BG {
font-weight: 300;
margin: 0 auto;
width: 65%;
padding: 20px 40px;
object-fit: contain;
max-width: 325px;
min-height: 200px;
border-radius: 5px;
display: table;
background-color: white;
position: relative;
box-shadow: 0 1px 3px 0 rgba(0, 0, 0, 0.2);
}
.open-card-BG::after {
content: '';
position: absolute;
top: 30px;
left: 100%;
width: 30px;
height: 30px;
background: url(../secure.svg) center no-repeat;
background-size: contain;
}
<header>
<img class="logo" src="logo.gif"/>
</header>
<main>
<div class="open-card-BG">main content</div>
</main>
<footer>
I am footer
</footer>
add body{margin:0} in your stylesheet.
By default body tag have margin of 8px in most major browsers.
body{
margin:0
}
main {
background-color: lightgrey;
padding: 50px;
}
header {
background-color: white;
width: 100%;
height: 50px;
}
.content-section {
background-color: lightgrey;
width: 100%;
}
.logo {
height: 20px;
margin: 15px 5px;
width: 116px;
}
.open-card-BG {
font-weight: 300;
margin: 0 auto;
width: 65%;
padding: 20px 40px;
object-fit: contain;
max-width: 325px;
min-height: 200px;
border-radius: 5px;
display: table;
background-color: white;
position: relative;
box-shadow: 0 1px 3px 0 rgba(0, 0, 0, 0.2);
}
.open-card-BG::after {
content: '';
position: absolute;
top: 30px;
left: 100%;
width: 30px;
height: 30px;
background: url(../secure.svg) center no-repeat;
background-size: contain;
}
<header>
<img class="logo" src="logo.gif"/>
</header>
<main>
<div class="open-card-BG">main content</div>
</main>

I am footer
</footer>
you can try giving the main tag a margin: 0 -10px, may solve your problem.
See the fiddle
you can add this code in your css:
body {
display: initial;
}
Try the following:
html, body {margin: 0;}
I am facing a typical situation. I am trying to practice dropdown menu in CSS. Here, the child div .dropdown (grey colored) appears whenever the parent div .content-small (green colored) is hovered upon. Please note, that I have used the .max-width property for all div's because I want all the div's to scale down/up whenever the browser window is scaled.
Now, what I want to do is that I want to increase the max-width of the child div dropdown. But whenever I try to enter a value above 50px, nothing happens. The width DOES NOT increases.
I know that this can be resolved by replacing max-width with only width in the .dropdown class. But if I do that, then the child div dropdown will not scale with the browser window. So in any case, I have to use .max-width property for all divs.
I also don't want to use media queries at this stage. In totality, this is what I am looking for:
I want to increase the width of the dropdown child div .dropdown, I also want it to be scaled along with the browser windows like all other div's (max-width)
I don't want to use media queries at this stage, since I am trying to practice with plain CSS
I don't mind if the .dropdown div DOES NOT remain the child of the parent .content-small (if a possible solution needs it that way)
Would appreciate a solution for this.

Hopefully this does not interfere with what you are trying to accomplish, but what about restructuring your code a little bit:
HTML
<div class="wrapper">
<div class="content">
<div class="content-small">Home</div>
<div class="container" style="height:60px;padding-top:10px;">

}
And here is:
UPDATED JS FIDDLE
[EDIT]
The + in the css select is saying to look for elements after the first criteria. So, in this case, the css is saying, when you hover over .content-small, it then targets the element AFTER .content-small with .dropdown and applies the css to it. Although it is not the most clear, here is a link of some documentation on css selectors
[SECOND EDIT]
I changed the code above to wrap the dropdown in a container and then set it so on container:hover it alters the visibility of .dropdown the same way, making it persist as visible if you are hovering over either. The reason I had to introduce a container is to give it that spacing between .dropdown and .content-small - which you can see I did with padding-top: and not margin-top: because margin would not have worked with the :hover
when you tell: width:100%; to an absolute child, it takes innerwidth and won't mind the borders,why should it overflow :) ?
You may size it with coordonates like you did for left, use right as well and drop the width:100%;
max-width will still be efficient and you may use margin:auto as well if you wish.

just practicing with css dropdown. In the following code, the .container div (blue colored one) contains the child dropdown div .dropdown (green colored one, I have disabled this color to avoid confusion). The container div is perfectly horizontally aligned to its above div .content-small (red colored one). Since I want the position and margins of all the div's to be mantained whenever I scale down the browser window, I used left: 41.66%; in percentage so that the container div should stay aligned to its top red div.
The container div stays aligned, but whenever the window is scaled down to lowest size, the container div shifts slightly to the right. PLEASE see the attached screenshot. Why is that?

That's because you're saying left: 41.66%;, which is not an accurate way to center. Instead, use this:
CSS
.container {
margin-left: auto;
margin-right: auto;
left: 0;
right: 0;
}
*{
box-sizing:border-box;
}
html,body {
margin: 0px;
height: 100%;
width: 100%;
left: 0px;
top: 0px;
background-color: rgba(0,0,0,1);
padding: 0px;
}
a {
color: rgba(0,0,0,1);
text-decoration: none;
}
a:hover {
color: rgba(0,0,255,1);
}
.wrapper {
height: 600px;
max-width: 960px;
margin-left: auto;
left: 0px;
top: 0px;
background-color: rgba(204,204,204,1);
margin-right: auto;
position: relative;
padding: 0px;
margin-top: 0px;
}
.content {

JSFiddle
I have an issue where the height of the "content body" div (below) is exceeding the bottom of the page (and behind the page footer). I want this div to scroll when there is long content, which it does now, but it doesn't scroll to the bottom of the div as it is beyond the page. I'm not sure what is causing the issue? Here is an example: http://jsfiddle.net/Gg6qY/
CSS:
html, body {
height:100%;
width: 100%;
overflow: hidden;
margin: 0;
}
header {
position: fixed;
width: 100%;
background: #006f3b;
color: #fff;
top: 0;
height: 60px;
padding: 10px;
}
#content {
position: relative;
height: 100%;
width: 100%;
padding: 60px 0 20px 0;
/* Header height and footer height */
margin: 0 auto;
/* Center content */
}
#sidebar {
position: absolute;
background: #191919;
color: #fff;
left: 0;
top: 60px;
bottom: 0;
width: 220px;
padding: 10px;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
-o-box-sizing: border-box;
-ms-box-sizing: border-box;
box-sizing: border-box;
}
#contentHeader {
position: relative;
left: 220px;
z-index: 100;
padding: 10px;
background: #fff;
border-bottom: 1px solid #191919;
-webkit-box-shadow: 3px 3px 3px #888888;
-ms-box-shadow: 3px 3px 3px #888888;
box-shadow: 3px 3px 3px #888888;
}
#contentBody {
position: relative;
background: #fff;
height: 100%;
margin-left: 220px;
padding: 0 10px;
overflow-y: scroll;
}
footer {
position: fixed;
width: 100%;
background: #999;
color: #000;
bottom: 0;
height: 20px;
text-align: center;
}
HTML:
<body>
<header>The header</header>
<div id="content">
<div id="sidebar">The Sidebar</div>
<div id="contentHeader">The Content Header</div>
<div id="contentBody">
<p>The Content Body</p>
</div>
</div>
<footer>The Footer</footer>
Thanks!
body and #content, goes beyond the window size as height:100% means height of the content area of the body which if you add to top and bottom padding, goes beyond the window. use
box-sizing:border-box to fix this.
contentBody to expand to maximum available height, make it absolute and set top and bottom.
contentBody should also work ideally with height 100%. Have not checked that.

Not sure what your intended goal is, but I think this is what you are looking for.
html{
min-height: 100%;
}
html, body {
width: 100%;
overflow: hidden;
margin: 0;
}
body
{
height: 100%;
}
if you know exactly where you want the top and bottom of all elements to be (which is seems like you do), its usually easiest to use 'top', 'bottom', 'left', and 'right' rather than 'width' and 'height', as padding adds to the width and height and will cause nasty overflows.. anyways this works on my machine..
html, body {
height:100%;
margin: 0px;
}
header {
position: absolute;
left: 0px;
right: 0px;
background: #006f3b;
