Center an image in main content while having a fixed sidebar - html

I have a sidebar navigation, and I'm trying to center an image in the main content (everything but the sidebar), but nothing I try works.
How can I center an image in the main content of my site, while having a fixed sidebar, where the image will stay centered even if I resize the page (make the site full screen, or half screen, etc.)?

You can try to set these styles for the image:
display:block;
margin:0 auto;

Make footer stay at bottom of site unless site content goes past vertical window size

I have a footer for a website. The footer is an full width image and it's a gradient fade (black to transparent), the text is centered with text-align: center.
These below images show exactly what's going wrong.
Footer misbehaving due in tall window: https://ibb.co/JH3rCdB
Footer behaving properly due in short window: https://ibb.co/wCRnb8p
I don't want the footer to be always fixed at the bottom. So, I don't want position: fixed. If the window is not that tall, the footer should only be visible when the user scrolls all the way down. This is working fine.
The problem is when a user's browser window is very tall. The footer is then visible right under the site content, and then there's a gap between the footer and the bottom of the window.
How do I solve this?
Position: fixed is not what I want, and Position: sticky with bottom: 0px doesn't work right.

Using Navbar fixed-top and keeping container below it fixed to its bottom even upon scrolling?

I am using “navbar fixed-top” from Bootstrap. And underneath it I have a container. What I noticed is whenever I scroll down the page, the container underneath the navbar starts to slide below the navbar (refer to attached photo). I am aware that this is an expected behaviour with fixed-top, but I am wondering is there away to always keep the container below the navbar fixed to its bottom even when the user scrolls down?
Get the height of your fixed element, let's say 50px, and then:
body {margin-top:50px}
Please add the header height as the margin-top of the container.. for example..
css
.container {
margin-top:100px; /*height of the header*/
}
OR
JQUERY
var headerheight = jQuery('header').outerHeight();
jQuery('header').css("margin-top",headerheight);

Difficulty tuning text placement on web page

I am having difficulty tuning the placement of text on my web page. Items on the page seem to float about and not lock down. I need them to stay static with respect to the background image.
For example, I have a div Item called "leftMenu" I want the left menu to stay approximately 20 pixels to the left of the background image. Things seemed to work until I had to center the background image. Now that the background image is centered, I seem to have lost the ability to lock down div positions with respect to the background.
When the screen is full size things look good, but when the page size is altered the leftMenu drifts all over the place. I'm currently going through a lot of trial and error using absolute and relative positioning, but I can't seem to get the right combination of settings to make the item stay put irrespective of the page size.

Any advice would be greatly appreciated.
Instead of using a big background taking a div of text and position it absolutely to the center, why not get a div that's exactly the size of the background image and center it using:
CSS:
html, body{
height:100%;
position:relative;
}
div.siteWrapper{
background: !VALUE;/* your background*/
padding: 0 0 0 0; /* the space top, right, bottom, left from the edge of the bg image to the content box of the image*/
width: !VALUE; /* width of your background - (left + right padding)*/
margin:100px auto; /* this will center your site horizontally and move it away from the top*/
}
HTML:
<body>
<div class="siteWrapper">
//everything in here
</div>
</body>
As per your requirement acc to me you have to create a wrapper div in which your whole stuff should be present and you need to use jquery/javascript to calculate the position from top, right, left, bottom of the wrapper to make it in center of the screen. For example lightbox of jquery. because when monitor size varies then resolution changes and the position of background image change according to that but content is set according to css set on the id/class on the elements.

Scroll background image of webpage with content

I have a webpage with a static CSS background, but the content is longer than the height of the image. This causes whitespace at the bottom after the image ends.
How can I make the image scroll along with the view of the user's screen?
background-attachment: fixed;

How to have a background image wider than the content area of a website (without scrollbars)

I've been given a design for a website, and am trying to implement it.
One problem I've run into is that the design has some background images (one for the header, one for the body, and one for the footer of the site) that are wider than the main content area of the site.
Simply putting them in as background images doesn't work, since expanding the header, body and footer divs enough to accommodate the backgrounds causes horizontal scrollbars to appear if the browser window is not big enough to fully show the backgrounds.
This is undesirable since the backgrounds are not really important for viewing the website, and I don't want scrollbars to appear for them (scrollbars should only appear once the browser is too small to completely show the content of the website).
The second technique is to have a separate, absolutely positioned div to show the header background image (and put it under an element with the browser window's size), and set its width to 100% so that it never exceeds the size of the browser window (and hence create scrollbars).
This works up to a point - however, when the window is too small, the background starts shifting around relative to the content since the "top center" position of the background is relative to the browser window, not the content area. At large sizes, these are effectively the same since the content area is centered, but at small sizes, only part of the content is shown, so the center of the content and the center of the browser window are different.
A good illustration of this problem that I've found is the Quicken website: http://quicken.intuit.com/. At large sizes, its cloud background looks fine, but if you make your window's width small enough, the clouds start shifting relative to the content (bad!).
Any ideas on how to fix this so that backgrounds images
don't create scrollbars since they are not part of the content of the site
are fixed relative to the content of the site (and don't shift around at small browser window sizes)
?
An ideal solution would be something like turning overflow to hidden on the body, but only for specified divs. Unfortunately I believe this is impossible.
I'd prefer a pure html/css solution, but I accept that I may need js to get the effect I want.
Thanks! (this is a complex issue, so if any clarification is needed, let me know)
UPDATE: Fixed this by setting min-width on the background div to the width of the content.
Set the min-width on the div containing the background image to the width of the content.
You need to have your header, content & footer have a width of 100%. And put the image in as a background image in these divs ... center it horizontally.
Inside the specific divs have a wrapper that is centered. and is the width of the content of them divs.
Like so.
HTML
<div id="header">
<div class="wrapper">
...
</div>
</div>
<div id="content">
<div class="wrapper">
...
</div>
</div>
<div id="footer">
<div class="wrapper">
...
</div>
</div>
CSS
div#header {
background: url(...) 50% 0; /* to center your background image horizontally */
}
div#content {
background: url(...) 50% 0; /* to center your background image horizontally */
}
div#footer {
background: url(...) 50% 0; /* to center your background image horizontally */
}
div.wrapper {
margin: 0 auto; /* to center the div horizontally */
width: 960px; /* or however wide it should be */
}
Hope this helps.
Am I missing something, or should you be using the CSS background-image property?
I had a look at the Quicken site, and to be honest the cloud background image shifting when the browser is resized shouldn't be worried about unless your background-image is most distinctive than a bunch of clouds.
See what I mean?
You could use the overflow property and set it to hidden on the div that cause a scrollbars to appear.
I had the same issue on a site that I worked on, and come up with the following solution, which works well if all your background images are the same width.
/*
A container div that is set to the 100% width, with the overflow set to hidden.
This hides the overflowing images if the window sizes is too small
*/
#bg_container {
position:absolute;
z-index:0;
top:0px;
width:100%;
overflow:hidden;
}
/*
A div that sets the size of the content and centers itself on the page.
*/
.bg {
margin:0 auto;
width:1000px; /* content size */
overflow:visible;
}
/*
Here I set the image away from the left edge of the div to center it to the content. The actual size of the image is 1500px.
*/
.bg img {
margin-left:-250px;
}
