In my html page I have an input component placed above a div component.
I want the input and the div to have the same width, the input has a "size" attribtue of 30.
If I use the "style" attribute of the div with "width : 30ch" or with "width : 30em" it doesn't seem to work, the div component is getting way wider than the input component in both cases.
Which attribute should I use to make the div's width match the input's size attribute?
code :
<input type="text" readonly="yes" value="a" size="30" ID="b">
<div id="c" style="width : 30ch"></div>
The size attribute sets the visible width in “characters”, and browsers interpret this differently. The ch unit, in supporting browsers, means the width of the digit 0, so it is defined very exactly, though it of course depends on the font. So these two ways of setting width are incommensurable.
To make a div element after an input element exactly as wide as the input element, the simplest way is to wrap them in a table with fixed layout. (Those who can’t bear with HTML tables can use a CSS table instead.) You don’t set the width of the div element at all in this approach; it gets its width from the table formatting. I have just set some content and a background color for it so that the width of the element is visible.
<table style="table-layout: fixed" cellspacing=0>
<tr><td><input type="text" readonly="yes" value="a" size="30" ID="b">
<tr><td><div id="c" style="background: green">Hello world</div>
</table>
try width attribute in both i.e. in input and div also , plus try to give width in %
html:
<html>
<input id="myinput"></input>
<div id="myDiv"></div>
</html>
css :
#myDiv{
width:x%(set x per your requirement)
}
Use this style to set exact same width for both your input and your div
input#b, div#c {width:100px;}

I am using bootstrap for layout. I have set max-width on the input control to 280px. But this causing input-group-addon not render properly when i use bootstrap's grid column size larger than 280px. input-group-addon does not stick with the control.
I have JSFiddle here
I guess input-group-addon always renders to the right of the column so there is a space between input control and addon.
How do i fix this without messing with max-width and col.
In your fiddle an .input-group-addon has width 32px, and both of .form-control (max-width: 280px;)and .input-group-addon (width: 32px) are included in the .input-group, then you just need to define max-width for .input-group:
.input-group {
max-width: 312px;
}
jsfiddle
I would NOT recommend to set the width of max-width of your inputs (or any other element), within Bootstrap.
Bootstrap elements are designed to fill all the available space. They can be made responsive very easily by using the built-in grid system. My recommendation is to limit their width by limiting the width of their container, like this:
<div class="row">
<div class="col-xs-6"><!-- NOTE THE 'XS' HERE -->
<div class="input-group">
<input name="FirstName" class="form-control" id="FirstName" type="text" value="399035034">
<span class="input-group-addon">+</span>
</div>
</div>
</div>

For some reason, the following HTML snippet wraps the % sign onto a new line (FireFox only):
<span class="label">
<input type="radio" />
<span>
<span>1,22</span>
<span>%</span>
<br />
</span>
</span>
And css:
.label {display: inline-block;}
Its a snippet, so it doesn't make much sense on its own, but I don't understand why this is happening, I think its valid HTML5. Can someone explain what the problem is with this snippet, because it works in Chrome and not in FireFx ?
DEMO
Adding white-space:nowrap; should fix it:
.label {
background-color: yellow;
display: inline-block;
white-space:nowrap;
}
jsFiddle example
Firefox renders this incorrectly.
Inline blocks should use the shrink-to-fit algorithm:
calculate the preferred width by formatting the content without
breaking lines other than where explicit line breaks occur,
calculate the preferred minimum width, e.g., by trying all possible
line breaks.
find the available width: in this case, this is the width of the
containing block minus the used values of 'margin-left',
'border-left-width', 'padding-left', 'padding-right',
'border-right-width', 'margin-right', and the widths of any relevant
scroll bars.
Then the shrink-to-fit width is:
min(max(preferred minimum width,available width), preferred width)
In this case:
preferred width is the width without any word wrapping.
preferred minimum width is the width of the widest element, in this case "1,22."
available width is the width of the document body, in this case 100%.
min(max(preferred minimum width,available width), preferred width) should therefore be equal to preferred width.
You can fix Firefox's behavior by changing your HTML or by using white-space:nowrap.
But I have another alternative: br is an inline element, but changing it to a block element fixes the problem.
Doing so shouldn't have an impact on any other br elements in your HTML (that I can think of).
Fiddle
What's happening is Firefox is interpreting your second span as being inline with the <br/> element. Try putting the <br/> element outside of the span wrapping the 2 spans like so:
<span class="label">
<input type="radio" />
<span>
<span>1,22</span>
<span>%</span>
</span>
<br />
</span>

Say I have a div. If I give it a height and width of 500*500px in HTML code, like this: <div width="500px" height="500px">test</div> it will not have dimensions of 500*500px unless it's filled with enough code/text to push it to those dimensions. However, if I set the exact same width and height with CSS (either inline CSS or external document) like this: <div style="width:500px; height:500px;">test</div> the dimensions are always what I set.
Why is there a difference?
Doing this isn't valid syntax. You cant add width & height attributes to a DIV the same as you can to a table or an image tag.
<div width="500px" height="500px">test</div>
This is valid syntax:
<div style="width:500px; height:500px;">test</div>
A div tag does not have the attributes width and height.
Dear community members,
I would like to position the text inside test in the center of a div. The code would look like the following:
<div id="main" style="width: 960px;">
<form>
<label for="test">Testing everything:</label>
</form>
Now if I try the following section of code:
<label for="test" style="width: 100%; text-align:center;">Testing everything:</label>
It does not center the text inside my main layer. Do I need to put a layer arround the label tags making it:
<div style="width:100%; text-align:center;"><label for="test">Testing everything:</label></div>
What is the standard method to accomplish that?
Thank you for your responses!
Your problem is very simple : label is not a block-level tag, which means that you can't give label elements a width. In other words, the width of a label element is the width of its content.
In your case, that means that it doesn't fill the entire width of your "test" div and then can't be centered.
To fix this, just add the following CSS property to your label :
display: inline-block;
This way, your label will be considered as a block for everything width (and height) related and your 100% width will be applied successfully, leading to a nicely centered text.
I'd like to center a submit button. How do I accomplish this? I dont know the width of the button, it may be flexible based on the text inside it. I'm trying not to use float and set the margin auto on it because that will require a width.
<input type="submit" value="may vary" />
If the width is variable, your best bet is to use the text-align property of the container. If that would effect other sibling elements in an undesirable way, consider wrapping the input in a div.
<div style="text-align: center">
<input type="submit" value="may vary" />
</div>
NOTE: The inline CSS above is just an example, feel free to create a css rule for the div.
