I am trying to understand which part of twitter bootstrap css code is responsible for the left padding whitespace in this example: http://twitter.github.com/bootstrap/examples/hero.html
but does not appear in this example: http://twitter.github.com/bootstrap/examples/starter-template.html
thanks in advance.
The first example is in a div with the class hero-unit. The hero-unit class has its padding set to 60px.
I guess, in this particular case, described above, it depends on your screen resolution. As Twitter Bootstrap uses responsive CSS, the width of the starter-template.html changes discretely, and in some cases padding is minimal. You could try changing your browser window width to see how padding (container width) changes dynamically. The same for hero.html, but as hero.html contains more content, the width in hero.html example switches earlier than in starter-template.html at the same screen resolution.

I am adding a menu to the side of my page using Bootstrap. I want the menu to stay at the top of the page when the user scrolls past it. I have discovered affix which is in bootstrap.js. However because I am using different col sizes for the screen I am struggling to get it to stay in the right place.
I have got it to start at the right time and to make it position the top correctly but the width and the right are not working.
I am using bootstrap 3.3.
I think that I will have to use percentages of the screen width and then also do media queries in the CSS.
JS Fiddle
I have solved it.
The element with affix needs to be a child to an element with a col- class on it. You then also have to set the width in pixels for each different screen width that bootstrap recognises.
i am sorry to disturb you all, but i want to understand how a certain margin responsiveness works.
As you can see on this site http://www.trade-ideas.com/about-us/ the navbar, the paragraphs, the h1, h2 and the footer maintain the same left-margin as you resize the browser window (with firefox the effect it's more clear).
It's like when the elements reach the limit of the left margin (that is mean zero), they restart just on the same distance (the same margin-left) that they where before i was starting resize my browser width.
I've noticed that the navbar included in bootstrap also has this left margin responsiveness: as i resize in width my browser's window, the navbar continue to stay in the same left-margin range, restarting every time he reach the zero margin-left.
In fact, on this bootstrap page you can find the exact same effect in all the page's elements (the navbar and the div box on the body) : http://getbootstrap.com/examples/navbar/
With firebug i've tried to search what parameter set this particular effect, but i'm not an expert, and i didn't find a solution.
So, my question is: this left-margin responsiveness it's generated by a set of #media queries instructions to a set of width? Or there is something that i'm missing?
Thank you in advance for all the help that you'll give me.

p.s.: i noticed that on http://getbootstrap.com/examples/navbar/ if i delete "margin-left:auto; margin-right:auto;" the effect that i need doesn't show up anymore.
I tried to create a div container with that margin auto on my site, but i was not able to ricreate the effect (maybe that "margin-left-right:auto" it's just a part of the effect).
The media queries are the ones that make sure the website is responsive. The example: http://getbootstrap.com/examples/navbar/ is using media queries to set the width of the container. If you set the media queries to change when the screen width is 700px and when you make the width of the screen smaller. The media queries will register the px of the screen and when the width of the screen is equal 700px the container will change.
My site has fixed width layout. I mean i'm not using responsive layout.
So I removed bootstrap-responsive.css file.
But it looks like bootstrap has some bug in the footer background while using fixed width layout.
I mean check this snapshot.
Can someone tell me how to fix that issue?
Based on the scrollbar at the bottom, it seems that your window size is less than the page size, since you removed the responsiveness. Based on a quick test on the Bootstrap doc, I think that you can fix this by adding width:100%; to the body tag. Everything is just set to fill the item containing it and nothing else has a width set (even the body tag by default). This should stretch the page to wrap around all elements instead of just filling the window.
UPDATE: CSS should be min-width:960px. Naturally, in other instances you would want to change this minimum width value, but for the Bootstrap CSS without responsiveness, this is the base grid system width.
I am using the Twitter Bootstrap framework for a responsive/fluid layout.
The top of the website spans across the full width of any screen but when I get down into the content, there is about a 20 px gap from the right side of the screen. This only seems to happen when the screen is small enough to pull in the part of the CSS that addresses:
#media (max-width: 767px){}
You can see a screen shot here:

And my test code is hosted here: http://demo.omnigon.com/christian_bovine/show-sxsw/
Like I said, on a large screen its fine, only on smaller screen, and its only the middle content. I have looked at the many times and I cannot see my problem?
You need to remove the negative margins on your #footer css selector. This declaration is essentially forcing your footer to be larger than its parent container.
Typically you would only use this technique when the parent container has padding and you want to negate the parents padding by applying a negative margin to the child element.
I've just spent the last few weeks learning how to properly design a layout. I basically thought I had everything perfect with my website layout and was ready to go about transferring the coding to Wordpress... and then I accidentally resized my web browser and discovered that all of my div layers were overlapping each other.
Here's what it looks like:
Basically it looks as though it's mainly my center content div that is being squeezed out, as well as my header image and navigation witch are in the same top div. My footer is also squeezed down as well. I've searched the internet for a solution to this problem and can't seem to find a thing.
How do I fix it so that my divs stay in place when the browser is resized?
as Walter said your CSS would be helpful. But, the main problem is that the content in the div is overflowing to other divs because the the content's div cannot contain all the content.
In your css, try setting the div's overflow property to either auto (shows scrolls bars) or hidden (to just hide the content if it goes outside's the div)
e.g.
overflow:auto;
or
overflow:hidden;
Express your widths and font-sizes in ems.
Here's a good calculator:
http://riddle.pl/emcalc/
Percentages will work, too.
Check the css in stackoverflow, and try resizing the zoom level in your browser here - you'll see everything resizes nicely at any zoom level.
I figured it out. Turns out that the width of my center content margin was dictated by margins instead of just a direct width (ie. 500px). So whenever the page was resized, the margins on the sides of the browser tried to stay as they were, thus making the entire column smaller. I just had to get rid of the margins and specify where I wanted the column to sit on the page and just justify a width for it.
you can also try the min-width. i am assuming the center div is fluid and sidebars are fixed-width.
Can you post some of your CSS?
The simplest way is to give all of your columns relatively sane width settings so that the size of the browser window doesn't affect the size of your layout. Getting fluid-width column(s) to behave is more complex and depends more on the specifics of your layout.
Check out the min-width property. Another option is applying another stylesheet when the viewport width is below x pixels with CSS3 Media Queries like so:
#media all and (max-width: 30em) {
/* Alternative narrow styles */
}
or so:
<link media="all and (max-width: 30em)"
rel="stylesheet" href="narrow.css" />
CSS3 Media Queries are still not widely supported, so you might want to look into a solution that applies the "narrow" style sheet with JavaScript through the window.onresize event. I'd recommend jQuery for such a solution.
I Had the same problem if you have a width and height in your DIV Container it wont change except the width unless you put a min-width. The problem I had was when I would make the browser window the divs would like go to the next line
so what I did was in the container I set a height and width. Before I didn't set a height I let the divs determine the heights.
