I’m a little confused on how to use Bootstrap’s containers. Am I supposed to nest the entire body of the webpage within a single container and then use rows for each section of the webpage? Or do I use individual containers for each section of my webpage?
For example, this...
<body>
<div class ="container-fluid">
<nav>Nav bar code</nav>
<div class="row">
<div class="col-*-*" > body stuff </div>
<div class="col-*-*" > body stuff </div>
</div>
<div class="row">
<div class="col-*-*" > more body stuff </div>
<div class="col-*-*" > more body stuff </div>
</div>
</div>
</body>
...or this?
<body>
<div class ="container-fluid">
<nav>Nav bar code</nav>
</div>
<div class ="container-fluid">
<div class="row">
<div class="col-*-*" > body stuff </div>
<div class="col-*-*" > body stuff </div>
</div>
</div>
<div class ="container-fluid">
<div class="row">
<div class="col-*-*" > more body stuff </div>
<div class="col-*-*" > more body stuff </div>
</div>
</div>
</body>
You can use both, it depends on your need. You are able to use as many as the container you want. For example, if you want to have different sections with the different background color you can use multiple containers. If you want to have different image background you can use multiple containers as well.

I'm changing a database using phpmyadmin with several html pages inside it and I would like to remove, from all these pages, all the <div> and other tags that contain a certain class or id.
Example:
Case 1
<div class="undesirable">
<div class="container">
<div class="row">
<div class="col1"></div>
</div>
</div>
</div>
Case 2
<div class="undesirable">
<div class="container">
<div class="row">
<div class="col1"></div>
<div class="col2"></div>
</div>
</div>
</div>
i would like to remove all <div> that contain the class="undesirable". In some cases, there is still the possibility of appearing as class="pre_undesirable", or something similar.
Initially I thought of using regex, but as there are variations in htmls, code breaks are occurring, as there is no way to know when the <\div> will end.
Possibly the answer would be HTML parser, but I can't understand how to use it. Any indication of where to start?
Since you are dealing with html, you probably should use an html parser and search for the removal target using xpath. To demonstrate, I'll change your html a bit:
$original=
'<html><body>
<div class="undesirable">
<div class="container">
<div class="row">
<div class="col1"></div>
</div>
</div>
</div>
<div class="keepme">
<div class="container">
<div class="row">
<div class="col1"></div>
<div class="col2"></div>
</div>
</div>
</div>
<div class="pre_undesirable">
<div class="container">
<div class="row">
<div class="col1"></div>
<div class="col2"></div>
</div>
</div>
</div>
<div class="keepme">
<div class="container">
<div class="row">
<div class="col1"></div>
<div class="col2"></div>
</div>
</div>
</div>
</body>
</html>
';
$HTMLDoc = new DOMDocument();
$HTMLDoc->loadHTML($original);
$xpath = new DOMXPath($HTMLDoc);
$targets = $xpath->query('//div[contains(#class,"undesirable")]');
foreach($targets as $target){
$target->parentNode->removeChild($target);
}
echo $HTMLDoc->saveHTML();
The output should include only the two "keep me" <div>s.
We can make use D3JS to remove or append any the HTML elements by class name or id.
We can make use of Select() and Selectall() for the selection of the particular elements in the HTML. Incase if we want to append any div tag use append('div') to insert the div for the data.
<script>
function remove()
{
d3.select(.undesirable)
.selectAll("li")
.exit()
.remove()
}
</script>
I have 2 different partial views that I am calling in my main view like this:
<div class="col-md-6">
#Html.Action("Chart", "Teams")
</div>
<div class="col-md-6">
#Html.Action("SeriesWinsChart", "Teams")
</div>
<div class="next-game">
<h3 class="text-center">The Next Game Is:</h3>
</div>
<br />
<div class="text-center">
<h3 style="color:red;">#ViewBag.NextGame</h3>
</div>
Now my problem is this:
All I have done is put background-color: green in my CSS for the class .next-game (honestly just to see what it looked like.. green is not what I am going to use)... I have gone into Inspect Element on IE and I cannot find the problem as to why the background is so big. I just want the background to be around The Next Game Is:
CSS:
.next-game{
background-color: green;
}
How do I shrink the background? I have tried width: 50%; height: 10px; //etc just to see the different changes but can't figure this out
UPDATE:
I have changed the HTML to:
<div class="next-game">
<h3 class="text-center">The Next Game Is:</h3>
<div class="text-center">
<h3 style="color:red;">#ViewBag.NextGame</h3>
</div>
</div>
<div class="col-md-6">
#Html.Action("Chart", "Teams")
</div>
<div class="col-md-6">
#Html.Action("SeriesWinsChart", "Teams")
</div>
This at least made the background render properly. So this has something to do with the partial views?
The most likely cause for this issue is that your twitter bootstrap columns have no wrapping row. You generally need all three (container, row, column) for it to render properly. What you're running into here is probably a clearfix issue. The columns are floated, which makes the next available non-floating element appear to "wrap" them. Below is a possible solution to the problem.
<div class="container">
<div class="row">
<div class="col-md-6">
#Html.Action("Chart", "Teams")
</div>
<div class="col-md-6">
#Html.Action("SeriesWinsChart", "Teams")
</div>
</div>
</div>
<div class="next-game">
<h3 class="text-center">The Next Game Is:</h3>
</div>
<br />
<div class="text-center">
<h3 style="color:red;">#ViewBag.NextGame</h3>
</div>
Other solutions include adding a .clearfix class to a wrapper for the columns or adding clear:both to .next-game.
You need
.next-game h3{
background-color: green;
}
(it's just for the header h3 inside the element with that class .next-game)
I'm trying to make a simple page header with bootstrap 3. Here's the code:
<div class="page-header">
<h1>Text on the left</h1>
<h3 class="text-right">This to the right but on the same line</h3>
</div>
Here's a jsfiddle to try: http://jsfiddle.net/DTcHh/2450/
Basically I just want to have text on the left and right inside the page-header, but on the same line.
The usual tricks of using float:left and float:right as with normal html "break" the page-header, meaning the text is properly aligned but is displayed outside (under) the page-header, which remains empty.
Any clues?
you can use "pull-right" and "pull-left" classes, with "clearfix" class after.
(Bootstrap 3)
<div class="page-header">
<div class="pull-left">
<h1>Text on the left</h1>
</div>
<div class="pull-right">
<h3 class="text-right">This to the right but on the same line</h3>
</div>
<div class="clearfix"></div>
</div>
also you can adjust line height on the h3 tag in the right, if you want to match with h1
Fiddle for Bootstrap 3: https://jsfiddle.net/darkosss/dy9wjk2q/
(as of Bootstrap 4.1)
use float-left and float-right instead. You still need the clearfix.
<div class="page-header">
<div class="float-left">
<h1>Text on the left</h1>
</div>
<div class="float-right">
<h3 class="text-right">This to the right but on the same line</h3>
</div>
<div class="clearfix"></div>
</div>
Fiddle for Bootstrap 4: https://jsfiddle.net/darkosss/eozs65qb/
if you are using Bootstrap, you should do something like
<div class="page-header">
<div class="row">
<div class="col-md-6">
<h1>Text on the left</h1>
</div>
<div class="col-md-6">
<h3 class="text-right">This to the right but on the same line</h3>
</div>
</div>
</div>
if you want to "stylize" the h1, h2, etc, change it to "display:block" and you'll have to add a "width" attribute anyway
use the following structure to position with bootstrap:
<div class= 'container'>
<div class='row'>
<div class ='md-col-4'>
<h1>Text on the left</h1>
</div>
<div class = 'md-col-4.col-md-offset-4'>
<h3 class='text-right'>This to the right but on the same line</h3>
</div>
</div>
Think of the row as a grid across of 12. So fist 4 left 3rd. 2nd div is the 3rd third with a 4 grid offset or gap.

I have a page that essentially behaving as I want it, except that I would like to place an image every so often along a horizontal scroll track. This JS Fiddle shows the code: http://jsfiddle.net/bretwhiteley/39cLc0vm/
So what I am trying to do is add an image that is the height of the "Scrolling" DIV 1000px from the left. I tried to use the following code, with no luck:
<div class="Timeline_Break" style="margin-left:1000px;">
<div style="margin-left:1000px"><img src="http://s.w-x.co/TWC_logo_100x100.gif" style="width:20px;height:130px"></div>
</div>
The Styling is:
.Timeline_Break {
position: fixed;
z-index: 99;
}

HTML
<div id="outer_div" style="overflow:auto; width:1238px; height:310px;">
<div id="inner_div" style="height:300px;">
<div id="child1" style="width:400px;">
</div>
<div id="child2" style="width:400px;">
</div>
<div id="child3" style="width:300px;">
</div>
<div id="child4" style="width:500px;">
</div>
<div id="child5" style="width:300px;">
</div>
<div id="child6" style="width:600px;">
</div>
</div>
</div>
What I want is the inner_div's width should go beyond the outer_div and child divs will remain on same line. I am adding child divs into inner_div by using jquery prepend and append method. Currently the maximum width inner_div is taking the width of outer_div and after that the line breaks.
I tried with display:inline-block, overflow:auto; and width:auto on inner_div but its not working.
Currently I am getting it to work using jquery by adding width dynamically to inner_div as I am dynamically adding child divs into inner_div. I would like to achieve it using css if possible.
Use table and table-cell properties to achieve this.
#inner_div{display:table;}
#inner_div div{display:table-cell;}
DEMO
you should use min-width on outer_div and float(or display:inline-block) on children of inner_div .
or use position absoulote on inner_div:
<div id="outer_div" style="min-width:1238px; height:310px">
<div id="inner_div" style="height:300px;">
<div id="child1" style="width:400px;display:inline-block">
</div>
<div id="child2" style="width:400px;display:inline-block">
</div>
<div id="child3" style="width:300px;display:inline-block">
</div>
<div id="child4" style="width:500px;display:inline-block">
</div>
<div id="child5" style="width:300px;display:inline-block">
</div>
<div id="child6" style="width:600px;display:inline-block">
</div>
</div>
</div>
or if you want fixed width of outer_div you can use position:
<div id="outer_div" style="width:1238px; height:310px;position:relative;white-space: nowrap;">
<div id="inner_div" style="height:300px;position:absolute; top:0 ">
<div id="child1" style="width:400px;display:inline-block">
</div>
<div id="child2" style="width:400px;display:inline-block">
</div>
<div id="child3" style="width:300px;display:inline-block">
</div>
<div id="child4" style="width:500px;display:inline-block">
</div>
<div id="child5" style="width:300px;display:inline-block">
</div>
<div id="child6" style="width:600px;display:inline-block">
</div>
</div>
</div>
by display table , inner_div can't get width larger than 1238!
also, I think , you can't add new element by css!
