position calculation calc() for absolute positioned element - css-position

I have this basic layout structure to control the general content width of all my website:
width: 90%
max-width: 1280px
Now I added an absolute positioned modal to my nav bar which should follow this positioning. I have an animated open close toggle in the nav bar and want the menu modal to always appear right below it.
I assume that I have to set the "right:" property accordingly. However I have a hard time to mathematically translate the above conditions to match the right: property.
Any idea for a suitable calc() code which does that?
My math skills fail me here. Help is much appreciated!
Working with plenty of calc() commands but unable to match the conditions.

Bootstrap Nav issue

I have problem with my nav bar on a theme I am developing. http://astanmedia.com/blog All is ok at full screen, but reduce the screen size so the the menu collapses and when you click / touch the toggle button, the dropdown refuses to break over the slider, no matter what z-index is set, or positioning used. on scroll I have the nav change to fixed at the top, and it displays fine once the slider has passed it. The dropdowns also function fine over the slider at full screen. Have tried to paste code here for 15 minutes, I must be doing it wrong, so I have linked to a paste bin of the code here http://pastebin.com/6war9TGu. Thanks in advance
I think I see your problem. It's not the z-index, it's the navbar-collapse style.
You have:
.navbar-collapse { max-height: 50px; }
You need something like:
.navbar-collapse { max-height: 275px; }
According to the Google Chrome developer tools, you can find the .navbar-collapse style on line 106 of your style.css. In your Pastebin it looks like it's on line 94.
As a note, once you fix the .navbar-collapse max-height, you'll also need to add a background color to your .navbar .navbar-nav class so that the drop down menu doesn't have a transparent background.
I'm seeing a few other little things on your style that may need adjustment, but I'm going to assume that you'll ask specifically about these issues as you go. To fix the question you asked about, the navbar-collapse should help.

Bootstrap 3 navbar jumping onto two lines rather than collapsing?

Think I'm missing the obvious here, but I have a Bookstrap 3 navbar that works great in desktop view but as I squeeze the width and it gets to tablet size rather than collapsing into the toggle menu it's jumping the menu onto two lines:

I've tried reducing the text size in the navbar via a media query but that isn't solving it.
What am I missing?
Appreciate it. Thank you.

One solution might be to change the point at which the navbar collapses, you can do this by creating a customized Bootstrap and setting the #grid-float-breakpoint to a larger number.
This variable unfortunately also influences the dt and dd inside a .dl-horizontal which might be a problem.
If you want to use a media query to reduce the font-size you can use the .navbar-default .navbar-nav > li > a selector. It however needs to become 9px at the smallest viewport size to still stay on a single row which is quite unreadable.
From the Bootstrap documentation:
Overflowing content
Since Bootstrap doesn't know how much space the content in your navbar needs, you might run into issues with content wrapping into a second row. To resolve this, you can:
Reduce the amount or width of navbar items.
Hide certain navbar items at certain screen sizes using responsive utility classes.
Change the point at which your navbar switches between collapsed and horizontal mode. Customize the #grid-float-breakpoint variable or add your own media query.
It goes on to say:
Changing the collapsed mobile navbar breakpoint
The navbar collapses into its vertical mobile view when the viewport is narrower than #grid-float-breakpoint, and expands into its horizontal non-mobile view when the viewport is at least #grid-float-breakpoint in width. Adjust this variable in the Less source to control when the navbar collapses/expands. The default value is 768px (the smallest "small" or "tablet" screen).

Header of a WP responsive theme won't properly remain on top at the top when scrolling; position:fixed and width:any% throws it out of whack

The WP responsive theme I'm working on:
http://www.wpexplorer.me/tetris/
I use Firebug for Firefox browser addon thingy to make changes before messing with the actual files. So if you have it or something similar, you will see that by adding position:fixed; to the #header section the header width shrinks well more than half its original size and the navigation menu is jacked up within the new shrunken space.
I have added other snippets of coding to the #header section like width:100%;, width:959px; and other percentages and pixels, which messes up the layout; especially when you resize the window down to what you would consider to be for a tablet and a mobile device - it's all out of whack. I can't get the sticky header for this theme to function or do right. Oh, I've also added z-index:200; to the #header section and margin:160px 0; to #main-content; these don't give me issues.
Adding the width: ; code to the #main-content doesn't seem to help either (which I read somewhere online that this was where the width code goes).
Anyway, does anyone know what code I need to make the header of this theme scroll up until it gets to the top of the page where it becomes sticky/static/fixed/on top (whatever the real term for it is) at all times? And, can you get it to work with the layout being in tact when the window is resized all the way down to the size of a mobile device?
Thanks.
This should work
#header-wrap{position:fixed;top:0;z-index:999;}
#pre-header{margin:20px 0 15px;width:960px;}
#main-content{margin:215px 0 30px;}
The position is fixed at the top using 0 with a z-index:999 you then need to set the width of the inner container pre-header 960px to match the rest.
You will need to setup the media queries for the other sizes you have setup. Easy, and Enjoy.
If you want the menu itself and not the social icons to become the top fixed bar without the social icons then you want to make a jquery scroll CSS change so that the #header becomes the fixed position.
It working with fixed header and social:
An illustration of it working without the social bar using a Jquery Scroll CSS change:
This is the way I would do it, I would move the menu down, and add the social icons to the menu itself. (Below is a screenshot of what I mean, the social icons are reduced to 75%)
PS. The social icons stand out to much so I would add a CSS3 Greyscale, and when the visitor hovers over them it turns on the color with a transition effect.
Hope this helps ;)

absolutely position simplemodal plugin on top of an existing div

I posted this a week or so ago:
Position simplemodal modal on top of an existing div
and thought that I had solved my problem, but when the window is scrolled, the modal container moves.
I think I need to change it from fixed to absolute positioning, but when I change it in the script, the right side of the container lines up with the left side of the div (but it does stay in the same place vertically).
Here's what I'm doing now:
$('.slider-caption #large-spot-two').click(function (e) {
$('#basic-modal-content-two').modal({appendTo:"#slider1", autoPosition: false});
return false;
});
What's the best way for me to keep the modal container above the div, whether the page is scrolled or not?
Thanks,
Wendy
The plugin was created to be fixed (not move when the page is scrolled, etc.). Changing the CSS position works until the page is resized or scrolled, as you have found.
The code required to change that behavior would require more work that I currently have time for. You might try BlockUI, as it sounds like that would fit your needs better?

Jquery UI Tabs Floating Divs in tab panel

I am having trouble trying to get a jquery ui tab panel's height to grow with floating divs within the panel.
the divs have specific data returning to these divs and I need them to float left and right to save ui real estate.
Does anyone know how i can fix this?
Actually, this is a well-known css issue. A discussion is here:
http://www.quirksmode.org/css/clearing.html
To summarize the article, any <divs> that you wish to function as both a tab pane and a float container should have these styles added to them either in your <style> or css <link> files:
overflow: auto;
width: 100%
This isn't a bug. It's intentional. The floating div literally lifts out of the container, and the container will not be aware of the floating div. At least, that was the goal.
You should do a search on here for "clearing floats" or other related css rules, because using the above will cause issues with certain browsers (in short: 'take care to test this, all the same').
