I realize that I'm using Bootstrap's form-horizontal class in a way that isn't quite documented, but I still don't understand why this doesn't work.
If I create a div with the form-horizontal class and add a couple of controls to it with widths specified using Bootstrap's grid layout classes, it works fine. For example, this displays as I'd expect:
HTML
<div id="container">
<div class="form-horizontal">
<div class="form-group">
<div class="col-sm-11">
<input type="text" class="input-sm form-control" placeholder="Enter some text">
</div>
<div class="col-sm-1 text-right">
<button class="btn btn-primary btn-sm"><span class="glyphicon glyphicon-info-sign"></span></button>
</div>
</div>
</div>
</div>
CSS
#container {
padding:10px;
background-color: gray;
}
The result is form which spans the full width of the page, with 10px of padding all around. Ideal, except that I want to contain the form within a div with a fixed width, and that's where it goes wrong.
Simply adding width:400px; to the #container class in the CSS causes the form to overflow the width of the div.
Is this a bug? How can I fix this so that the form stays within its container?
I've created an example fiddle here: http://www.bootply.com/pP9gsJQipi. Note that simply removing the width value from the #container class causes the form to display as desired, albeit at 100% width of the page.
Simply add a width of 100% to the .form-group. The .form-group will now size 100% according to the width of the #container.
CSS
#container {
padding:10px;
background-color: gray;
width: 400px;
}
.form-group {
width:100%;
}

I am working on a grid layout using css flex styling and want a total css solution, if possible, I have the means to fix it with javascript.
When a row exceeds the viewport width, it displays the scrollbar,
but when you scroll, the styling of the row element remains the size of the viewport,
it does not seem to "wrap" all of its children.
see : fiddle
Try scrolling, you will see the yellow row (.sk_row) class does not appear around all its children.
A solution would be fine, but I would like to know why the parent does not visually contain all children. I think I may be missing some key concept about flexboxes...
Duplicate of fiddle code...

display:flex;
border:1px #000 solid;background:#666;
flex:0 0 100px; height:30px; margin:0 5px;
align-items:center;justify-content:center}
Note : this is not the same as question
That op wants to change child behaviour, I want the parent to change.
It's not working the way you want because .sk_row inherits the width, in this case from #frm0:
#frm0 { width: 420px; }
With the class .sk_scrl you can't see it very well, because it's set to:
.sk_scrl { overflow: auto; }
If you use your browsers developer tools (assuming you have any), you'll see that the elements wrapped around your .itm_val divs are all 420 pixel wide. The reason the .itm_val divs are all visible outside of their container, is because they are "overflowing" out of their containing div.
Here's an example for how the width-inheriting-thing works:
<div class="container">
<div class="element"></div>
</div>
If you set the the width of .container to 50%, it will use up half of the available width within the window. If, however, you want .element to take up the full width of the window, you will have to adjust the width like this:
.element {
width: 200%;
}
If it were set to 100%, it would only be as wide as .container.
Here's a fiddle: http://jsfiddle.net/Niffler/n8hmpv13/
I want to add buttons beneath a <h1> tag, but don't know what CSS to use to make it so. The image below shows a likely scenario, with the "Main_Page" title and the buttons forming each part of a separate div. I tried using the margin-top property, but wish to know which other techniques can I use.
I used the following CSS for the buttons div, while nothing for the name div.
#wiki-page-head .buttons
{
float: right;
margin-top: -30px;
text-align: right;
max-width: 500px;
}
<div style="display:inline;">
<h1 style="display:inline;vertical-align:-3px;" >Ton titre</h1>
</div>
<div style="display:inline;">
<input type="button" value="Edit"></input>
<input type="button" value="Discussion"></input>
<input type="button" value="History"></input>
</div>
With this code, you should get a result like that the image below, is that what you want ?

I tried like all combinations:
<div class="row">
<div class="span7 offset5"> box </div>
</div>
or
<div class="container">
<div class="row">
<div class="span7 offset5"> box </div>
</div>
</div>
changed span and offset numbers...
But I cant get a simple box perfectly centered on a page :(
I just want a 6-column-wide box centered...
edit:
did it with
<div class="container">
<div class="row" id="login-container">
<div class="span8 offset2">
box
</div>
</div>
</div>
But the box is too wide, is there any way I can do it with span7 ?
span7 offset2 gives extra padding to the left span7 offset3 extra padding to the right...
Bootstrap's spans are floated to the left. All it takes to center them is override this behavior. I do this by adding this to my stylesheet:
.center {
float: none;
margin-left: auto;
margin-right: auto;
}
If you have this class defined, just add it to the span and you're good to go.
<div class="span7 center"> box </div>
Note that this custom center class must be defined after the bootstrap css. You could use !important but that isn't recommended.
besides shrinking the div itself to the size you want, by reducing span size like so... class="span6 offset3", class="span4 offset4", etc... something as simple as style="text-align: center" on the div could have the effect you're looking for
you can't use span7 with any set offset and get the span centered on the page (Because total spans = 12)
Bootstrap3 has the .center-block class that you can use. It is defined as
.center-block {
display: block;
margin-left: auto;
margin-right: auto;
}
Documentation here.
If you want to go full-bootstrap (and not the auto left/right way) you need a pattern that will fit within 12 columns e.g. 2 blanks, 8 content, 2 blanks. That's what this setup will do.
It only covers the -md- variants, I tend to snap it to full size for small by adding col-xs-12
<div class="container">
<div class="col-md-8 col-md-offset-2">
box
</div>
</div>
Sounds like you just wanted to center align a single container.
The bootstrap framework might be overcomplicating that one example, you could have just had a standalone div with your own styling, something like:
<div class="login-container">
<!-- Your Login Form -->
</div>
and style:
.login-container {
margin: 0 auto;
width: 400px; /* Whatever exact width you are looking for (not bound by preset bootstrap widths) */
}
That should work fine if you are nested somewhere within a bootstrap .container div.
add the class centercontents
/** Center the contents of the element **/
.centercontents {
text-align: center !important;
}
#ZuhaibAli code kind of work for me but I changed it a little bit:
I created a new class in css
.center {
float: none;
margin-left: auto;
margin-right: auto;
}
then the div become
<div class="center col-md-6"></div>
I added col-md-6 for the width of the div itself which in this situation meant the div is half the size, there are 1 -12 col md in bootstrap.
Follow this guidance https://getbootstrap.com/docs/3.3/css/
Use .center-block
.center-block {
display: block;
margin-left: auto;
margin-right: auto;
}
wrap the div in a parent div with class row then add style margin:0 auto; to the div
<div class="row">
<div style="margin: 0 auto;">center</div>
</div>
I'm sure this will be ridiculously simple, but whatever... I'm trying to display a text area with a button to its right, similar to how StackOverflow displays a comment field with button when one clicks the 'Add Comment' link...the problem I'm experiencing is with the button alignment; it appears to align at the top right of its div (see image), I want to align it at the bottom left. I've tried using text-align, align, nothing works to move that pesky button, I used padding-top to move the button down, but padding-right appears to have no effect, but there's got to be a better way than padding. I need it to be cross-browser compatible as well.
Here is the html/css I'm using...
.newComment {
position: relative;
width:475px;
background-color:WHITE;
}
<div class='newComment'>
<div style='float:left;width:375px;'>
<textarea style='border:1px solid #888;overflow:auto' rows='3' cols='40'>comments </textarea>
</div>
<div style='float:left;width:75px;'>
<input type='submit' value='Add Comment'/>
</div>
</div>
The reason why it is not adjacent to the textarea is because the div encompassing the text area is too large. If you inspect element on Chrome, you will notice where all the elements are.
I'd suggest you do not put them in separate divs if you want them stuck together.
<style>
.newComment {
position: relative;
width: 475px;
background-color: white;
}
</style>
<div class='newComment'>
<textarea style='border:1px solid #888; overflow:auto' rows='3' cols='40'>comments</textarea>
<input type='submit' value='Add Comment' />
</div>
You've set the widths of the container divs but you haven't specified the height, so your padding is not taking. I've provided a sample below so you can visually see what is happening...
http://jsfiddle.net/g6JSU/
Below is a possible solution with the button aligned to the vertical center:
http://jsfiddle.net/g6JSU/1/
try this
.newComment {
position: relative;
width:475px;
background-color:WHITE;
}
<div class='newComment'>
<div style='float:left;width:375px;'>
<textarea style='border:1px solid #888;overflow:auto' rows='3' cols='40'>comments </textarea>
</div>
<div style='float:left;width:75px;'>
<input style="float: left; margin-top: 20px;" type='submit' value='Add Comment'/>
</div>
</div>
How can we have the text "Create New Position" be vertically centered?
HTML/CSS is below.
Adding margin-top:5px to the "Create new.." div helps but it seems hacky.
<div style="margin-top:5px">
<div style="float:left">Create new position</div>
<div style="float:right"><input type="submit" id="x" value="Save"></div>
<div style="clear: both;"></div>
</div>
The following will work based on creating a line-height which is equivalent for both items.
HTML:
<div class="row">
<span class="left">Create new position</span>
<span class="right"><input type="button" value="Save" />
</div>
CSS:
/* REMOVE THIS PORTION FOR YOUR IMPLEMENTATION, IT IS EXAMPLE ONLY */
* { font-family: Tahoma, sans-serif; font-size: 12px; }
.row { border: 1px solid #ccc; }
/* END EXAMPLE ONLY PORTION */
.row { height: 24px; }
.row > span { line-height: 24px; }
.left { float: left; }
.right { float: right; }
The trick is to set the .row containing DIV to be 24px tall, and also set the contained SPAN elements to have a line-height of 24px. By doing this, you tell the browser how much vertical space to take up for the line of text.
Note, however, that 24px is not the important part - the important part is identifying how tall your button is, which is based on your CSS and your selected font for the button itself.
The reason the example I'm giving you works to vertically center in this case is based on the EXAMPLE ONLY CSS I put in at the top - which says the font-size should be 12px. The default browser sizing (at least in Chrome) is then going to provide a little extra margin and padding around the button, as well as a border - which results in a total height of roughly 24px, and this appearance:
The border is created by the example CSS also, and is only there to show you that the vertical alignment is correct. Once you remove .row { border: 1px solid #ccc; }, it will disappear.
Here is a JSBin which shows it working:
http://jsbin.com/otekil/1/edit
The below may help you.
<div align="center">
</div>
So it would look like this maybe:
<div align="center">
<div style="float:left">Create new position</div>
<div style="float:right"><input type="submit" id="x" value="Save"></div>
<div style="clear: both;"></div>
Make the line-height of the interior div the same height as the height of the exterior div.
Example:
<div style="margin-top:5px; height: 100px;">
<div style="float:left; line-height: 100px;">Create new position</div>
<div style="float:right"><input type="submit" id="x" value="Save"></div>
<div style="clear: both;"></div>
</div>
Slightly different approach but you don't need the floats, vertical-align should work fine in this instance IMO:
<div>
Create new position:
<input type="submit" id="x" value="Save" style="vertical-align:baseline;" />
</div>
This method should work in all browsers, is stable, and allows you to easily choose the object to which you want your content centered. The empty container is the only problem I have with this method, but I can easily overlook it when comparing the pros/cons of other methods.
Solution:
You use a div at half of the parent's height to push your content block (push_to_center class), then reduce it by half the content height (content class).
In-line style declaration
<div style="float:left; height:50%; margin-bottom:-55px;"></div>
<div style="clear:both; height:110px; position:relative; width:200px;">
<div style="float:left">Create new position</div>
<div style="float:right"><input type="submit" id="x" value="Save"></div>
</div>
Complete HTML page (see it working):
<html><head><title>Test Center Div</title>
<style>
.push_to_center {float:left; height:50%; margin-bottom:-55px;}
.content {clear:both; height:110px; position:relative;}
</style>
</head>
<body>
<div class="push_to_center"></div>
<div class="content" style="width:200px; height:110px;">
<div style="float:left;">Create new position</div>
<div style="float:right;"><input type="submit" id="x" value="Save"></div>
</div>
</body>
</html>
To exclude the Save button from centering simply move it out of the Content classed div (put it earlier in the page flow if you want it above, and below in the page if you want it at bottom):
I always used such trick:
style="height: 30px; line-height: 30px; vertical-alignment: middle;"
Having fixed height plus the same height as line height plus middle vertical alignment.
Maybe the above are better answers, I'm posting this because it's simple and worked for me. :)
Addressed this by adding margin-top:4px to the "Create Position" div. This was the only solution I could get to work!!
This will work.....
<table style="height:500px;width:100%">
<tr>
<td>
<div style="margin-top:px;vertical-alignment: middle;height: 30px; line-height: 30px;">
<div style="float:left;">Create new position</div>
<div style="float:right"><input type="submit" id="x" value="Save"></div>
<div style="clear: both;"></div>
</div>
</td>
</tr>
