I'm using sticky.js to accomplish a sticky header. Everything is working except when I scroll down, the header moves up about 10-20 pixels and to the left about 10-20 pixels as well. I'm not sure what I'm doing wrong but if anyone knows why this might be, i'd really appreciate the help.
Here is a link to the site in progress http://barret.co/dad/services.html.
Any help or suggestions appreciated.
To counter the vertical movement, you'll have to instruct sticky.js (if possible, can't tell) to set the top of .sticker to 10 pixels (the top padding of the <aside> element), not 0.
Then:
the css for the logo image should be changed to something like this:
#logo {
margin-left: 5%;
margin-bottom: 25%;
margin-top: 20px;
}
I removed the
display: block;
max-width: 100%;
margin: auto;
as you can see. You'll have to play around with the left margin value to position it to your liking.
Then:
Because of the width of the .sticker element being in percentages, the actual width of the element changes when it becomes 'fixed'. This is because the element is now considered a child of the viewport and not the html parent element. This squishes your content from 310 to roughly 273 pixels. Set a width (in percentages) on your .sticker element that suits your design and be done with it.
Hope it helps!

I am soo confused right now. Coding really isn't my thing, so I believe that I messed up majorly somewhere which creates this problem:
I'm trying to make a sticky footer. The footer does stick--but only if I make my main content DIV (the white centered box) relative. I need the height of that DIV to stretch with the content (which will contain a PHP script that'll pull from my Wordpress blog--so naturally, I need it to adjust as necessary). If the DIV stretches longer than 500px, there's a weird two-scrollbars things going on, & I hate that. I like the relative DIV, but I would love to rid of all the extra scroll space, as well as making sure it stetches/regresses with content & the footer stays where it is.
I hope that's not too confusing. I'd just like someone to look over my source code & see where I'm going wrong. Thank you for any help.

nice website :)
You need to make the footer fixed,
use this CSS
#footer {
position: fixed;
height: 80px;
clear: both;
background-color: #fff;
bottom: 0;
left: 0;
right: 0;
}
and take overflow: auto; off of #main
what this does is tell the footer to stay 'fixed' to the bottom of your viewport, so it will always stick to the bottom of your screen.. and taking overflow:auto; off will give your #main the natural ability to expand it's height depending on the content inside it.
http://jsfiddle.net/9fCfE/1/
.fixed {
width: inherit;
height: 95%;
overflow-x: hidden;
overflow-y: auto;
position: fixed;
}
footer {
width: 100%;
}
Fixed div must be always on top and shouldn't cover the footer when I scroll.
100% height or from top to footer.
How can I do it?
The simplest answer is to drop the z-index of the fixed region so that when it would otherwise cover the footer, it instead moves behind it. You'll need to make sure the footer is position: relative;.
Fiddle example
If, instead, you want the two to never intersect, you're in for a harder challenge.
The best way to do it would to be giving your fixed element a fixed height, giving your footer a fixed height, and making sure that the fixed element height + the footer height <= the screen height.
Fiddle example
Those are really your only options - you essentially have to design around it. To the best of my knowledge, there is no way to dynamically shrink the fixed element when it intersects with other elements on the page (ignoring the rest of the elements on the page is the purpose of position: fixed, after all).
I've cobbled together a quick and dirty implementation of what you asked using jQuery, offset(), scrollTop() and height()
Here's the jsfiddle example.
Is this what you wanted? If so - why? :)
I don't see any visual difference between this method, and the one where the fixed element goes under the footer.
I have an issue that only affect Chrome. Furthermore its only visible when the screen is at certain widths.
I've created a fiddle that can replicate the issue.
http://jsfiddle.net/T8LvA/63/
When you rollover the red box the width of the parent is animated to reveal more of the red box.
You may need to adjust the width of the html pane several times before you see the wobble,
Any thoughts on how best to resolve this?
Thanks
Use float:right instead of positioning it absolutely.
http://jsfiddle.net/T8LvA/70/
It happens because when you change the width, it extends to the right - then it's reflowed and moves back to the left to the correct position, which causes the wobble. Floating it to the right always keeps it there.
To clarify: you'll need to replace position: absolute width float: right on both #widget and .hidden for the correct result.
if you use postion you need use left and top, in this case it is useless.
Try fx you css in this way
#wrapper{
width: 100%; // was 600px
height: 100px;
margin: 0 auto;
//position: relative;
}
I've having an issue with the background images i have embedded into my carousel. click here I've noticed when i click from one slide to another the background image on my site moves out of place. The margin-top for my carousel is current set to margin-top:-275px; and the background image is set to margin-top:-64px; I am slight concerned about these settings.
Does anyone have a solution to this problem?
In order to activate the slides click the thin red tab under the nav bar
I guess that's because you have
.rslides li {
top:0;
}
It does nothing with position:relative (and the current slide has it), but it moves down the slide with position:absolute (hidden slides).
When you click a tab, there's a moment in which the new one is fading in, but it doesn't have position:relative yet. Then, in that moment, the new slide isn't where you want.
So remove that line.
The jumping is occurring because you are switching the LI items from position: absolute; to position: relative; at the end of the animation toggle. This can be avoided by removing your CSS rule:
.rslides li { left: 0; top: 0; }
Specifying width and height is fine, but as soon as you specify left and top - then switch from relative to absolute positioning, you get that jump you're seeing.
As for the positioning of each panel - it has to do with the way you are laying out your boxes. The sizes you are specifying are not large enough for the content you are providing. For instance: <div id="header"> is 37px tall, which is the appropriate size for the social media buttons, but you also have it as the container for the #nav-menu UL - which is another 102px tall.
It appears that in order to correct this and make things overlap, you are using negative margins - which is getting you all thrown off.
My suggestion would be to use a standardized layout system, such as any of the following:
http://cssgrid.net/
http://960.gs/
http://www.1kbgrid.com/
http://foundation.zurb.com/docs/grid.php
And use it to perform your layout tasks, rather than trying to self-craft overlapping layers with mixed absolute/relative positioning.
Alternatively, if you're going to go the overlapping layers route (again, not suggested), really commit to it. Position things absolutely throughout the layout.
In order to accomplish this, you might consider CSS rules like:
#header {
display: block;
position: absolute;
left: 50%; top: 0px;
height: 139px; /* Your Social media links height + nav buttons height */
width: 1018px; /* Your current width */
margin-left: -509px; /* Half the width - centers on page */
}
Again - this is MUCH more work, MUCH harder to maintain and MUCH less elegant - but will yield you at least a consistent spacing / sizing.
First, here's is my rough example: http://demindu.com/sandbox/simple.html
What I'm trying to do:
Create a content div: let's say 400px tall and 700px wide, like the example. The content box has a margin of 50px in each direction. The content div should always be centered both vertically and horizontally, regardless of screen resolution. The black background should extend from the centered content area all the way to the right side of the screen, but not to the left.
The only way I can think of possibly doing this is something using window.innerWidth & window.innerHeight in JavaScript, but I don't know enough to know if this is even possible.
The amount of blank space above and below the middle section would need to be:
window.innerHeight - height of the div (in this example: 500px [400px box with two 50px margins]) / 2
The blank space to the left of the black bar would need to be:
window.innerWidth - width of the div (in this example: 800px [700px box with two 50px margins]) / 2
My question to you is: Is this possible in JavaScript? Is this possible somehow with pure CSS?
You can do this entirely in CSS with 4-point absolute positioning. You will need two elements:
The first item spans from the right of the screen to the center where the content is positioned. This element uses absolute positioning for the top, left, and right coordinates of the element (we can leave bottom unspecified as it's taken care of by the height.)
The second item is nested in the former. This item has a fixed width to ensure the content itself remains in the specified width you've chosen. We can also set the height and padding on this object and the parent will inherit it's height. Don't use margins to simulate padding - it can cause cross browser issues when you're just trying to do some positioning tricks as we are here.
So your HTML code would look something like this:
<div id="my_centered_design">
<div id="my_centered_design_content">
<p>This is just some example text.</p>
</div>
</div>
And you're CSS would look like this:
div#my_centered_design {
background: #000;
margin-left: -400px;
margin-top: -250px;
left: 50%;
position: absolute;
right: 0;
top: 50%;
}
div#my_centered_design_content {
background: #333;
height: 400px;
/* I think you actually want padding for
the effect you're trying to accomplish */
padding: 50px;
width: 700px;
}
Essentially this is the same trick as the Joe2Tutorial except we are applying additional positioning rules to adhere the centered element to the right side of the screen.
I think this pure css solution would suit you best: http://www.joe2torials.com/view_tutorial.php?view=37
A very quick google resulted in this piece of code.
this code does not align a div in the middle. what you actually for your own website is that you put the following div css
.main {
width: 140px;background-color: #252525; float: left;margin-top: 25px; }
inside a table that is aligned to be centered. so, basically you're using the table's centering feature to center your left floated div simply as a content. you're not doing anything through div or css for that matter. the piece of css code you offered doesn't not anything about centering a div in the middle.
