I have a following navbar code using twitter bootstrap
<div class="navbar navbar-inverse">
<div class="navbar-inner">
<div class="container">
<ul class="nav">
<li class="active">Home</li>
<li>Link</li>
<li>Link</li>
</ul>
</div>
</div>
</div>
and the output is
When I remove "width: auto" from ".navbar .container{width:auto}" in bootstap.css the output becomes
and is the output I am expecting.
https://github.com/twitter/bootstrap/issues/2093 shows "width: auto" as an intended feature.What am I doing wrong here?
<div class="navbar navbar-static-top navbar-inverse">
<div class="navbar-inner">
<div class="container">
<ul class="nav">
<li class="active">Home</li>
<li>Link</li>
<li>Link</li>
</ul>
</div>
</div>
</div>
This should do it
I found another solution to the above issue.
Add navbar-fixed-top class to the main navbar div.
And add
.navbar-fixed-top{
position: relative;
}
to your css rule.
This restricts the menu from pulling it to the left and worked fine while I was developing a theme for wordpress.
If you look at the Bootstrap basic nav bar example you will see that there is a margin on either side of the navbar. This is because for a non-fluid container, your page will occupy a fixed width and the navbar uses that width.
If you want the navbar to extend across the entire page, you need to use a class="container-fluid" but in a fluid layout, the menu items (by default) will flow from the left-hand side of the page.
In your code, you are using both container and container-fluid which is incorrect, and as per the Bootstrap documentation, you need to place the nav in a container - not embed a container in your nav tags.
I solved this by removing the width: auto definition from .navbar .container in bootstrap.css.
Not an ideal solution (editing bootstrap.css in general) but it was much simpler than applying all the responsive widths to the selector.

What is the best practice if a modifier effects all elements of a block?
In my current project I have a header. This header changes to position: fixed if the user scrolls.
In the header there's the main navigation, the logo, a language switcher and a phone link:
<header class="header">
<div class="header__logo">...</div>
<nav class="nav nav_main">...</nav>
<nav class="nav nav_lang-switch">...</nav>
<div class="header__phone-link"></div>
</header>
On scrolling, the header get's the modifier header_fixed:
<header class="header header_fixed">
<div class="header__logo">...</div>
<nav class="nav nav_main">...</nav>
<nav class="nav nav_lang-switch">...</nav>
<div class="header__phone-link"></div>
</header>
The header looks completely different if it's fixed: the color changes, the main navigation turns to a hamburger icon navigation, the icons of the lang switch become smaller and so on.
Now I could go the nested way in CSS:
.header_fixed .nav_main {...}
.header_fixed .lang-switch__icon {...}
.header_fixed .header__phone-link {...}
...
Or every block or element that changed can get it's own modifier class.
What are your thoughts about that?

Marcus
Nesting is just fine here, see https://en.bem.info/methodology/css/#nested-selectors
There's this fixed header element (a block element), with an absolute positioned nav element with a menu, and another fixed element as the logo:
<header>
<nav id="menu">
<ul id="menuItems">
<li class="menu-item" role="menuitem">About</li>
<li class="menu-item" role="menuitem">Contact</li>
</ul>
</nav>
<div id="topLogo">
<h1>MAIN</h1>
<h2>SUB</h2>
</div>
</header>
The <header> doesn't have dimensions, it doesn't take-up space (check out with an inspector tool).
I need it to take space (and still be fixed).
Look at the JSFiddle to see it with the complete CSS as well:
https://jsfiddle.net/5amo16q8/4/
Changing the nav to float:left and removing the position:absolute seem to create to desired result.
See: https://jsfiddle.net/5amo16q8/8/
I am having an issue with IE positioning for li items position:absolute; . The structure works fine in all other browsers like this:
HTML
<div class="container">
<div class="container-nav">
<ul class="nav">
<a href="#">
<li id="an-item">Hi</li>
</a>
<ul>
</div>
<div>
All parent containers are position:relative and work fine in other browsers. In IE with this format the items start the positioning relative to outside the container. The only way I got it to be right is adding position:absolute; to the <a> tag. When I do this though it throws off all the other browsers. Any way to fix this? Should I use conditional CSS or is that not a standard anymore?
you can't put an anchor tag inside a ul IE doesn't allow that other browser are way friendly with some invalid HTML structure but not the case with IE what you can do is the following :
<div class="container">
<div class="container-nav">
<ul class="nav">
<li id="an-item">Hi</li>
<ul>
</div>
<div>
put your anchor tag inside the li
I'm experimenting with Bootstrap 3.2. I'm trying to create a fixed at top navigation bar but I'm running into two problems:
The navigation bar overlaps the content below it.
The navigation bar seems to be going far off the screen to the right. This makes my button in the navigation bar not visible unless the window width is dragged to a smaller size.
For the first problem, I've followed the Bootstrap example tip by adding a class to my css file, including this file below the Bootstrap css file in the html document, and then referring to the class.
.navbar-height{
body{padding-top: 200px;}
}
<body class="navbar-height">
Though, this seems to do nothing (as you can see I specified the number really high hoping to see a dramatic change, which did not occur).
Here's my the navigation bar:
<header id="header-navigation">
<div id="nav-bar-container">
<nav id="nav-bar" class="navbar navbar-default navbar-fixed-top" role="navigation">
<div id="nav-item-container" class="container-fluid">
<div id="drop-down" class="navbar-header">
<button type="button" class="btn btn-default navbar-btn navbar-toggle collapsed" data-toggle="collapse" data-target="#user-dropdown">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<div id="home-button" class="navbar-left">
<a class="navbar-brand" href="#"><img alt="Brand" src=""></img></a>
</div>
</div>
<div id="user-dropdown" class="navbar-collapse collapse">
<ul class="dropdown-menu" id="dropdown-items" role="menu">
<li>
<div class="list-group-item">
<div class="row-picture">
<img class="circle" src="" alt="icon"></img>
</div>
<div class="row-content">
<h4 class="list-group-item-heading">Placeholder</h4>
<p class="list-group-item-text">Placeholder</p>
</div>
<div class="list-group-seperator"></div>
</div>
</li>
<li><span class="glyphicon glyphicon-log-out"></span></li>
</ul>
</div>
</div>
</nav>
</div>
</header>
As a quick break down of the above code, I have a <header> tag which will hold the navigation bar. Within this <header>, I have a containing <div> (id="nav-bar-container") which only purpose is to act as a container for the navigation bar (maybe I'll add something else to the header and want to keep the bar seperate). Then, I have the actual <nav> which has the appropriate classes (or so I think): "navbar navbar-default navbar-fixed-top". The next <div> (id="nav-item-container") holds the components of the navigation bar. The following <div> (id="drop-down") contains the button (which seems to disappear at full-screen) and a link with a "brand", which always seems to be visible. The last major <div> contains the "drop down" content for when the button is pressed.
My Question: why is my navigation bar overlapping the content below it and over extending to the right hiding the button?
Ok, first thing, you don't need the <header> tag, so feel free to remove that.
Second, from the Docs on navbar-fixed-top, you need to have padding:
body { padding-top: 70px; }
Notice you applied it to the heading style; that won't work. Apply it to the body and it works fine.
As far as the 2nd issue, I don't actually see any horizontal scrolling when I removed the
<header> tag, so I think that may have been causing an issue.
Checkout this Bootply example:
Bootply Example
To see what I mean. It's your code with the tag removed. Hope that helps!
Change..
.navbar-height{
body{padding-top: 200px;}
}
to..
body.navbar-height{
padding-top: 200px;
}
You want the padding on the body itself. This will push you body down 200px giving you a gutter at the top for your fixed navbar.
most likely you'd want to adjust this padding depending on the actual height of your navbar.
As for problem number two, where I believed the navigation bar to be overflowing off the screen to the right, was just a mistake in the layout of the code. I was grouping the button I wanted to display on the right with the brand in the "navbar-header". What this does is display the brand but use that button only on a mobile screen to hide or show its associated dropdown. That is why I was only seeing the button when I made the width smaller by dragging the window. To fix this problem I removed the button and placed it within the appropriate code block. So, my "navbar-header" now looks like this:
<div id="drop-down" class="navbar-header">
<div id="home-button" class="navbar-left">
<a class="navbar-brand" href="#"><img alt="Brand" src=""></img></a>
</div>
</div>
Now, next within the id="nav-item-container" parent div, I create a list of items (ul). This list contains the items within the navigation bar and has the classes "nav navbar-nav navbar-right". Each list item (li) within this list is an item within the navigation bar. Dropdown buttons and their contents must be contained within the same list item (li). Make sure the parenting list item to the dropdown elements contains the class "dropdown". Then, the button or link should have the "dropdown-toggle" class applied to it. And the dropdown items themselves (which too can be a list of items and often is) should have the class "dropdown-menu". For example:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
<ul class="nav navbar-nav navbar-right">
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
<span class="glyphicon glyphicon-align-justify"></span>
</a>
<ul class="dropdown-menu" id="dropdown-items" role="menu">
<li>
<div class="list-group-item">
<div class="row-picture">
<img class="circle" src="" alt="icon"></img>
</div>
<div class="row-content">
<h4 class="list-group-item-heading">Placeholder</h4>
<p class="list-group-item-text">Placeholder</p>
</div>
<div class="list-group-seperator"></div>
</div>
</li>
<li><span class="glyphicon glyphicon-log-out"></span></li>
</ul>
</li>
</ul>
Note, in the snippet I didn't include the parenting nav, div, or header so it may not work exactly how it should. Also, I figured the majority of this out on my own by referencing the Bootstrap component page, as well as, the Bootstrap material design page (a plugin to Bootstrap that gives everything the Google Material Design look and feel). So, I'm not sure if all the "rules" I stated are mandatory or if there are other ways to achieve this.
As for problem number one, I just made a silly mistake with the css and the two other answers provided correct ways of fixing it. All I had to do was fix the body css like so:
body{
padding-top: 200px;
}
bHello I have a question regarding jQuery mobile css.
I have a page and inside that page I have header,content and footer. Now inside the content I have a grid that has a bunch of textfields:
<div data-role="page" id="calculator">
<div data-role="header" data-id="header">
<div data-role="navbar">
<ul>
<li></li>
<li></li>
<li></li>
<li></li>
</ul>
</div><!-- /navbar -->
</div><!-- /header -->
<div data-role="content">
<!-- below is the grid -->
<div class="ui-grid-b">
<div class="ui-block-a"><div class="ui-bar ui-bar-c" style="height:65px">Afvallen:<input type="text" name="m1cut" id="m1cut" value=""></div></div>
<div class="ui-block-b"><div class="ui-bar ui-bar-c" style="height:65px">Onderhoud:<input type="text" name="m1onderhoud" id="m1onderhoud" value=""></div></div>
<div class="ui-block-c"><div class="ui-bar ui-bar-c" style="height:65px">Aankomen:<input type="text" name="m1bulk" id="m1bulk" value=""></div></div>
</div>
</div><!-- /content -->
<div id="footer" data-role="footer" data-theme="b">
<div data-role="navbar">
<ul>
<li>Omhoog</li>
</ul>
</div>
</div><!-- /footer -->
</div><!-- /page -->
Now, normally the grid seperates in 3 pieces of 33/33/33 (%), but I changed it too 100% each, so that it would stack on top of each other. I did that with the following css:
.ui-grid-b .ui-block-a,
.ui-grid-b .ui-block-b,
.ui-grid-b .ui-block-c,
.ui-grid-b .ui-block-d {
width:100%;
}
Now, that worked as it should, but the problem I have now is that I want to have a navbar inside the header (as you can see in the code) but it also stacks up and has a width of 100%. When I remove the css for the grid it works perfectly (25/25/25/25) but then again the grid is 33/33/33 instead of 100 each, does anyone know why this css causes this conflict and how to solve it, its weird because I only edit the grid while it affects the navbar aswell?
My question is if you want your divs to fill 100% why bother altering jQuery Mobile's css? You can just do a 3 divs and set width 100%.
I'd suggest you that you revert the css modification you did on jQuery Mobile's css and add custom css for your divs.
Update
I tried your problem in jsfiddle and everything works fine after changing the css too http://jsfiddle.net/jEYNy/
.ui-grid-b .ui-block-a,
.ui-grid-b .ui-block-b,
.ui-grid-b .ui-block-c,
.ui-grid-b .ui-block-d {
width:100%;
}
instead of changing your jQuery Mobile's css, add your changed code as custom css and import it into your code and see how it behaves.
