Column BG image won't extend to 100% height - html

I have a left column with a background image and another background image for the body so it fills the rest of the screen. I have content area to the right of the left column that will extend vertically past the browser window. With the left column set to 100% height, once I scroll down the background image for the left column will not extend past the original size of the screen. Is there a pure css way to have the left column extend past the original height of the browser window, to match the content area?

min-width: 1100px;
height: 100%;

Add the rule background-attachment: fixed; to your body element.

please check demo http://jsfiddle.net/n9Tcv/
var right_height = jQuery('#right').height();
var left_height = jQuery('#left').height();
jQuery('#left').height(right_height);​
you know how to use jQuery? if you have any doubt just reply me, i do this code like this situation

If I understand your question correctly you need to use the equal height columns technique. Googling for a solution brought me here and here. There you may find different ways to make the sidebar to be equal to the main content area. Simply choose the best one :)

When you set html and body tag height to 100%, they both set their height to inner height of the browser window which means they both have the same value and also a fixed value. And since your divs, #container and #left, are childs of and relative to body element, they set their 100% height accordingly, i.e to inner height.
Moreover, if you need an answer for the question: Then why does the div #right extend?, it is because it does not extend but overflows. And since you don't tell the body or #container or #right to set the overflow property to hidden, none of them prevents such kind of browser behavior. And in this case you assume the original window height is the height which overflow causes.

How to make a page scroll to bottom of image

I dont really have anything to show, but i'll try to explain.
I am using HTML and CSS and i have a background image the size of the moon. (3840x18509 pixels). How can i add this as a background on the page, get it to scale automatically to the screen, and make it scrollable? What i mean by that is that i want to be able to scroll all the way to the bottom of the long picture. using :cover is not doing it, and when i set height:18509px; The image gets wider than it's supposed to be so that it cuts out on the sides.
I want the website to be as wide as the original picture, and as high as the original picture. I want to show the entire picture in a way that it fits the screen width, but must be scrolled downwards to reach the bottom. Thanks in advance.
body, html {
margin: 0;
padding: 0;
border: 0;
background-image: url("HuronWP.png");
background-repeat: no-repeat;
background-size: cover; I dont want it to cut the image height,
i want to scroll down to see the rest.
}
}
If you know the exact size of the image you simply have to set the aspect-ratio of <body> to match the image: body { aspect-ratio: 3840 / 18509; }
body {
margin: 0;
background-image: url('https://www.tacoshy.de/stackoverflow/3840x18509.jpg');
aspect-ratio: 3840 / 18509;
}
Alternativly you could insert the image directly and use width: 100% to fit the screen while maintaining its aspect-ratio.
img {
width: 100%;
display: block;
}
/* for styling purpose only */
body {
margin: 0;
}
<img src="https://www.tacoshy.de/stackoverflow/3840x18509.jpg">
I think you want to scroll you image whenever it becomes wider or longer than your page. You can do this simply using css overflow property.
overflow:scroll;
Just adding this to our code it will work fine.
Whenever the image height or width will be larger than you container then it will automatically be a scrollable.
Here I have created a div class and put my image inside this div.
<div class="image">
<img
src="https://cdn.pixabay.com/photo/2015/04/23/22/00/tree-736885__480.jpg"
alt="img"
/>
</div>
Now I am changing the height and width of my <img> so that it will overflow the <div> class.
height and width of image.
img {
height: 1000px;
width: 1000px;
}
height and width of outer div
.image{
height: 900px;
width: 900px;
overflow: scroll;
}
This property will be valid only when the outer div must have smaller height and width than the inner,

Mechanics: Why does it take 3 height: 100% tags to make a background fill screen?

I'm trying to learn the basic mechanics that explain why it takes 3 height: 100% tags to fill the screen with a background image. Intuitively I understand why .bg needs height: 100% or alternately height: 100vh;However I don't understand why the BODY tag needs height: 100% and I especially don't understand why the HTML tag also needs it. If any one of these 3 lines is deleted the effect stops working. Is there something in the spec that explains this? I can't find it.
Here is my Fiddle
html {
height: 100%;
}
body {
height: 100%;
margin:0;
padding:0;
}
.bg {
height: 100%;
background-image: url(https://placehold.it/600x600);
background-position: center;
background-size: cover;
}
<div class="bg">
</div>
The .bg div is inside both the body and the html tags. Since it's height:100% fills its parent's height, the parent tags, html and body must also be the full height:100%. If they are not then even though the .bg div is filling height:100%, that 100% comes from a parent which is not the full screen height, so .bg is only able to fill whatever the parent's height was.

How can I put a left not-fixed div on my webpage which height it is the maximum height it could be?

I am trying to put a div on the left side of my webpage that has not to be fixed and has to be 100% of the height and 30% width. I mean, that if you scroll, it will be scrolled also and it will not be fixed in the same position all the time.
The problem that I am having it is that when I put height: 100%; it does not cover the height that I am indicating to him. It only covers the full height when I set position:fixed but never when I set it to static, absolute or relative.
What I though it is that it could be that I had to set width: 100%; and height: 100%; to the <html> tag but it does not seem to have any difference if I compare it with <body> tag (I know there are differences between both tags but I do not know if in this case they will be aplied, I think no).
Here is my html code:
<html>
<head>
</head>
<body>
<h1>This is a prove</h1>
<div id="proveDiv">
<h1>Hello</h1>
</div>
</body>
</html>
Here is my CSS code:
html{
/* position: relative; I comment these lines because I saw that there are not any effect
width: 100%;
height: 100%; */
}
body{
position: relative;
width: 100%;
height: 100%;
}
#proveDiv{
position: fixed;
width: 30%;
height: 100%;
background-color: red;
}
Here is the fiddle in which you can see the effect. Just try to change the position attribute on proveDiv id css and you will se what I refer to.
I am stuck here and I cannot find any solution by myself or in SO. Am I missing something?
Thanks in advance!
Set the min-height of the div to view-port height like min-height: 100vh;. Updated fiddle
#proveDiv {
width: 30%;
min-height: 100vh;
background-color: red;
}
Based on your description, this is the working demo that I came up with.
http://codepen.io/BenCodeZen/pen/JXLbjN
The solution is based on a display: flex; on a parent container and defining the height of the element using height: 100vh; instead of 100%. By using flexbox, it will allow you more control over the layout for responsive design.
Let me know if you have any questions.
The reason why this happens is because, when you use the attribute fixed, for some reason, the div's height will increase because it's inherited by default from its container. In this case, when your div is fixed and its height is set to 100%, the div takes the full height of its container which is the body.
PS: In case you want the div to have its initial height, you can use position:initial.
On the other side, using position:relative is your best option.
By default, the div will have its own initial height which depends on its content. When you have more text inside your div, it will automatically increase its height.
To solve your problem, use a relative position and set the height as you want. (100% will make the div take the height of the body)
Note that it is important that you set both the body & html tag's height otherwise it won't work. (If you need further explaination, just comment below)
This is how your CSS should be:
html,body{
width: 100%;
height: 100%;
}
#proveDiv{
position: relative;
width: 30%;
height: 100%;
background-color: red;
}

Footer Background image shrinks when changing width of window

I have a footer i created for a website, but for some reason when i change the width of the window the background image seems to just disappear throughout the right side as i'm shrinking the width of the window.
The footer is supposed to stretch 100% accross the bottom of the screen and does so until i start shrinking the width of the window to a certain point.
You can see an example of my issue Here
Any ideas how to fix this? I am totally stumped. Maybe i did something wrong with width?
The width of #footer is set to auto, and the content within (#content-wrapper) has a fixed width.
This is causing the horizontal bars to appear.
To solve this, you can set overflow:hidden to the parent div (#footer).
Try this:
#footer {
background-image: url("images/footer-bg.png");
background-repeat: repeat-x;
height: 451px;
margin: auto 0;
width: 100%;
overflow: hidden; //What you're looking for.
}
If you also want the inner div (#content-wrapper) to dynamically resize itself, use a percentage, instead of a pixel dimension for width:
#footer #content-wrapper {
height: 451px;
margin: auto;
width: 83%;
}
Hi i have check to your demo page you have define your footer width 1265px and now
than your define min width your html or body as like this
body, html {
min-width: 1265px;
}
because your max width is 1265 define to your footer so that you define same width your body or html

Trying to make large background image remain centered with an auto margin centered content div, but bg image should not affect layout

i want a background image that is larger than the content, which will remain centered with the content, but will not affect the layout (meaning no scrollbars to accomodate the background image). the content must be centered using margin: auto; so that the left side will remain flush with the left side of the viewpane, when the viewpane becomes smaller than the content.
I have seen this question asked several times, and have tried quite a few solutions, but none of the accepted answers have actually worked.
Edit to Clarify
This question is still a bit murkey, so I will attempt to clarify with some images showing what I need. In these images, green is the background image, red is the main content, and blue is the browser's viewpane.
A: When the viewpane is smaller than both the background image and the main content, the left side of the content remains flush with the left side of the viewpane, the background image remains centered to the main content, the viewpanes scrollbars will only scroll out to the right edge of the main content (and not to the right edge of the background).
B: When the viewpane is larger than both the background image and content, both remain centered to the viewpane.
C: When the viewpane is the same size as the main content, the background image should remain centered to the main content, no scrollbars should be present.
Updated Answer: I still have spent way too much time on this :-), especially when it ended up so simple. It allows for a background to be sized based on the height of the container, which seems to be different than yunzen's solution. Now does use margin: 0 auto;. Still grows with container height.

You can view the original, more complex answer which does not use auto margin.
HTML:
<div id="Bkg">
<div id="Content">Content goes here. </div>
</div>
CSS:
#Bkg {
width: 100%;
min-width: 300px; /* equals width of content */
background:url('http://dummyimage.com/400x20/ffff00/000000&text=Center') repeat-y top center;
padding-bottom: 50px;
}
#Content {
width: 300px;
margin: 0 auto;
}
I guess this is what you want
HTML
<div id="content">
content<br/><br /><br/>
content<br/>
</div>
<div id="background"><div></div></div>
CSS
html, body {
height: 100%;
}
#background {
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
/* this is the height of the bg image */
min-height: 600px;
z-index: -1;
}
#background > div {
margin: 0 auto;
background: url("http://lorempixel.com/800/600/sports/2") no-repeat 50% top gray;
width: 100%;
height: 100%;
/* this is the height of the content */
min-width: 500px;
/* this is the width of the bg image */
max-width: 800px;
/* this is the height of the bg image */
max-height: 600px;
z-index: -1;
}
#content {
/* these are just some numbers */
width: 500px;
height: 400px;
border: 1px solid gold;
margin: 0 auto;
background: rgba(255,255,255,0.2);
}
Well, if it expands past the browser's window size, it's going to create a scrollbar for the entire window. I wasn't sure exactly what scrollbar you're trying to prevent.
max-width tells it "under no circumstances should this box be bigger than this width." So a box bigger than that will simply expand past the parent's boundaries.
See the jsFiddle.
If I'm understanding the question right, I believe this is what you're wanting.
.main-container
{
height: 1005px;
left: 50%;
margin-left: -560px;
position: relative;
width: 1120px;
}
To hide the scrollbars, you can add
overflow: hidden;
For horizontal only:
overflow-x: hidden;
Try this then:
<div id="wrapper" style="position:relative;margin:auto;width:200px;height:200px;">
<div id="image" style="position:absolute;top:0px;left:-100px;width:400px;height:400px;background-image:url(your_bgimage);background-repeat:no-repeat;background-position:top center;">
<div id="content" style="position:absolute;top:0px;left:100px;width:200px;height:200px;"><p>
<p>/* YOUR CONTENT */</P>
</div></div></div>
For some reason I couldn't get the z-index work, but if you can, you can put your content in the wrapper too, and content is not needed.
Given your original diagram I assumed that the background image was intended to be that - an image, possibly hi-res, rather than a repeated pattern. You may want to play with css3 background-size property which is handy for this specific purpose. It is well supported by modern browsers and regresses reasonably well if you have to support IE8 and under.
body {
background-image:url(/*nice higher res picture*/);
background-size:cover;
background-repeat:no-repeat;
}
