css textbox with a floating button beside it - css

I'm working on a mobile template for my site and I want a textbox inside a div to be width:100% with an html submit button beside it, however the button always seems to wrap to the second line. Can someone help me out with some CSS for this?
<style type="text/css">
.form_input {}
.form_submit{}
</style>
<div>
<input type="text" name="s" value="" class="form_input" />
<input type="submit" value="Search" class="form_submit" />
</div>

The wrapping happens because of the workings of the css box model. 100% means 100% of the context box. So the input field will fill the line completely -> the submit button has to wrap to the next line. You can give the input box a width of e.g. 80% and the submit button a width of 20%.
I guess what you really want to do is something like input{ width: 100% - 200px }, submit {width: 200px}. That is not possible with css2.

Set the div to position:relative; and then set both the textbox and submit button to absolute position:
div.box{ position:relative; }
input[type="text"]{position:absolute;left:0;top:0;}
input[type="submit"]{positon:absolute;right:0;top:0;}

If you set the textbox to width: 100%;, then it will take up all the space available, and always push the submit button down.
This code specifies a width for both input elements:
.form_input {
width: 70%;
}
.form_submit{
width: 20%;
}
and they will be on the same line. (70% + 20% = 90% because I've left a little room for margins.)

Content-dependent div with labels

<div id="combobox">
<label><input type="checkbox" id="tag3"
name="checkbox" onclick="toggleTag('tag3')"/>DialogProc</label><br/>
<label><input type="checkbox" id="tag2"
name="checkbox" onclick="toggleTag('tag2')"/>fds</label><br/>
</div>
I'm using div as a container for checkboxes with labels. Corresponding css:
div#combobox
{
max-height: 150px;
overflow: auto;
border: 1px solid #000000;
}
And this does exactly what I want - vertical scrollbar (no horizontal one), capped height and content-dependent width. With one exception - it doesn't take vertical scrollbar's width into account. So when there are few lines/checkboxes and the vertical scrollbar isn't needed - the width of the div is the width of the widest checkbox. But when the scrollbar appears, the width of the div is unchanged:
The label is broken into 2 lines. I fixed this with span:
<span><label><input type="checkbox" id="tag4"
name="checkbox" onclick="toggleTag('tag4')"/>InitializeWindow</label></span><br/>
and:
span
{
white-space:nowrap;
}
but the div's width is still incorrect:
Is there any way to get make the div take scrollbar's width into account with just html/css? If not, what's the best way to do it with javascript?
I would suggest you to use something like this:
(function($) {
$.fn.hasScrollBar = function() {
return this.get(0).scrollHeight > this.height();
}
})(jQuery);
So you can check if there is a scroll activated:
$('#combobox').hasScrollBar(); // returns true if there's a `vertical` scrollbar
after that you can expand the size of your div with some javascript...this would probably work for you:
$('#combobox').css("width",$('#combobox').width+13); //this is just an example to use 13px but you need to test it in all browsers to see how it all works

CSS Absolute Positioning

I have a div inside a field set that looks like this:
<fieldset>
<legend>Device</legend>
<label id="select-6-container">
<select id="select-6" name="device_select" style="display:none"></select>
</label>
</fieldset>
<div id="ctrl">
<button type="button" id="restart1" name="button1" onclick="window.location.reload()" value="Restart Wizard">Restart Wizard</button>
<button type="button" id="gotostep2" class="gotostep2" name="button1" value="Next Step">Next Step</button>
</div>
My select box is populated with YUI and then shown (notice that its hidden on load). My CSS for the box looks like this:
#ctrl {
margin-top: 102px;
margin-left: -200px;
position: absolute;
width:100px;
}
But when My select box is generated, the ctrl box moves down everytime! Do I have my CSS wrong? Or is it because the select box is generated by Javascript after the page has loaded?
I should mention that when YUI renders the select box as a menu button it changes it's markup to be a button, I didn't think this should matter because the positioning of ctrl is what I'm trying to change.
Any advice would help!
Thanks!
Your div doesn't seem to be inside the fieldset, as you had mentioned.
Try to assign a position to the div using top, right, bottom and/or left. The div's position will be then depending on the next positioned parent element, so have an eye on that as well.
If all of this doesn't work — please post as well the surrounding mark–up and CSS.

width:auto for <input> fields

Newbie CSS question. I thought width:auto for a display:block element meant 'fill available space'. However for an <input> element this doesn't seem to be the case. For example:
<body>
<form style='background:red'>
<input type='text' style='background:green; display:block; width:auto'>
</form>
</body>
Two questions then:
Is there a definition of exactly what width:auto does mean? The CSS spec seems vague to me, but maybe I missed the relevant section.
Is there a way to achieve my expected behavior for a input field - ie. fill available space like other block level elements do?
Thanks!
An <input>'s width is generated from its size attribute. The default size is what's driving the auto width.
You could try width:100% as illustrated in my example below.
Doesn't fill width:
<form action='' method='post' style='width:200px;background:khaki'>
<input style='width:auto' />
</form>
Fills width:
<form action='' method='post' style='width:200px;background:khaki'>
<input style='width:100%' />
</form>
Smaller size, smaller width:
<form action='' method='post' style='width:200px;background:khaki'>
<input size='5' />
</form>
UPDATE
Here's the best I could do after a few minutes. It's 1px off in FF, Chrome, and Safari, and perfect in IE. (The problem is #^&* IE applies borders differently than everyone else so it's not consistent.)
<div style='padding:30px;width:200px;background:red'>
<form action='' method='post' style='width:200px;background:blue;padding:3px'>
<input size='' style='width:100%;margin:-3px;border:2px inset #eee' />
<br /><br />
<input size='' style='width:100%' />
</form>
</div>
"Is there a definition of exactly what width:auto does mean? The CSS

No one actually answered the above part of the original poster's question.
Here's the answer:
http://www.456bereastreet.com/archive/201112/the_difference_between_widthauto_and_width100/
As long as the value of width is auto, the element can have horizontal
margin, padding and border without becoming wider than its container...
On the other hand, if you specify width:100%, the element’s total
width will be 100% of its containing block plus any horizontal margin,
padding and border... This may be what you want, but most likely it isn’t.
To visualise the difference I made an example:
http://www.456bereastreet.com/lab/width-auto/
ORIGINAL answer using Angular: Because input's width is controlled by it's size attribute, this is how I initialize an input width according to its content:
<input type="text" class="form-list-item-name" [size]="myInput.value.length" #myInput>
UPDATE for JavaScript (10/01/2022): My original answer was from the time I was studying Angular. If you need pure, Vanilla JavaScript the solution is even simpler:
<input type="text" oninput="this.size = this.value.length">
Or add an "input" event listener to your input html element and run a code like this:
const myInput = document.querySelector('input');
myInput.addEventListener('input', this.typing);
(...)
typing(e) {
e.target.setAttribute('size', e.target.value.length);
}
Obs: Depending on the browser, input may restore to its default size of something between 150px and 250px if/when size gets the 0 value. In this case, just add +1 to value.length:
<input type="text" oninput="this.size = this.value.length + 1">
OR:
typing(e) {
e.target.setAttribute('size', e.target.value.length + 1);
}
As stated in the other answer, width: auto doesn't work due to the width being generated by the input's size attribute, which cannot be set to "auto" or anything similar.
There are a few workarounds you can use to cause it to play nicely with the box model, but nothing fantastic as far as I know.
First you can set the padding in the field using percentages, making sure that the width adds up to 100%, e.g.:
input {
width: 98%;
padding: 1%;
}
Another thing you might try is using absolute positioning, with left and right set to 0. Using this markup:
<fieldset>
<input type="text" />
</fieldset>
And this CSS:
fieldset {
position: relative;
}
input {
position: absolute;
left: 0;
right: 0;
}
This absolute positioning will cause the input to fill the parent fieldset horizontally, regardless of the input's padding or margin. However a huge downside of this is that you now have to deal with the height of the fieldset, which will be 0 unless you set it. If your inputs are all the same height this will work for you, simply set the fieldset's height to whatever the input's height should be.
Other than this there are some JS solutions, but I don't like applying basic styling with JS.
It may not be exactly what you want, but my workaround is to apply the autowidth styling to a wrapper div - then set your input to 100%.
If you're willing to include a little JavaScript to solve this, you can get exact sizing. This doesn't rely on approximating width with size or ems, doesn't rely on any hardcoded element widths, and works for e.g., type="number", which don't accept a size attribute.
The trick is to get your input sized exactly like a span with the same content, by actually having an invisible span with the same content.
Put your input inside a div along with a span that mirrors the input's value. Give both the input and the span the same styling, give the input 100% width, then hide the span and absolute-position the input to sit on top of the span.
This way, the container (and thus the input) are automatically sized by the visual appearance of the content of the invisible span.
https://codepen.io/spiffytech/pen/abwWRqo
<div id="relative-parent">
<span id="size-calibration"></span>
<input id="autosized-input" />
</div>
<style>
#relative-parent {
position: relative;
/* Have some width if the input is empty */
min-width: 1em;
/* Adjust size to match the span */
width: min-content;
}
#size-calibration {
visibility: hidden;
/* Prevent the span from wrapping the text when input value has multiple words, or collapsing multiple spaces into one */
white-space: pre;
}
#autosized-input {
position: absolute;
left: 0;
width: 100%;
}
#size-calibration, #autosized-input {
/* Normalize styles that the browser sets differently between spans and inputs.
Ideally, use a "CSS reset" here. */
font-family: "Arial";
padding: 0;
/* Demonstrate that this works for input with custom styles */
font-size: 24px;
}
</style>
<script>
function updateSize() {
const span = document.getElementById('size-calibration');
const input = document.getElementById('autosized-input')
span.innerText = input.value;
}
document.addEventListener('DOMContentLoaded', () => {
const input = document.getElementById('autosized-input');
input.oninput = updateSize;
// Provide some initial content
input.value = "I'm sized exactly right!"
updateSize();
})
</script>
After tried methods all above and failed, I workaround by modifying   width property in style by unit em:
tgt.style.width = `${(tgt.value.length + 1) / 2}em`
The only option I can think of is using width:100%. If you want to have a padding on the input field too, than just place a container label around it, move the formatting to that label instead, while also specify the padding to the label. Input fields are rigid.
Answer 1 - "response" gave a nice answer/link for it. To put it in short, "auto" is the default, so it is like removing any changes in the width of an element
Answer 2 - use width: 100% instead. It will fill the 100% of the parent container, in this case, the "form".
Using JQuery
$(document).on('input', '.input-fit-width', (e) => {
$(e.currentTarget).attr('size',e.currentTarget.value.length);
})
Nowdays, flex or grid makes it much easier , it overrides default style/behaviors of https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input#size which has a default value set at 20 see : https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input#size
Giving you 2 plain CSS options without requiring JavaScript nor setting width to 100% and deal with box-sizing.
flex/flex-grow
<form style='background:red;display:flex;'>
<input type='text' style='background:green; flex-grow:1'>
</form>
grid
<form style='background:red;display:grid;'>
<input type='text' style='background:green;'>
</form>
Jquery way of adjusting size of input automatically.
In general:
$('#my_input_id').width( ($('#my_input_id').val().length) + "ch" );
On text input:
$(document).on("input", '#my_input_id', function () {
$(this).width( ($(this).val().length) + "ch" );
});
I think the simplest solution is to set parent element's width:
form{
width: 100%!important;
}

How do I set the size of an HTML text box?

How do I set the size of an HTML text box?
Just use:
textarea {
width: 200px;
}
or
input[type="text"] {
width: 200px;
}
Depending on what you mean by 'textbox'.
Your markup:
<input type="text" class="resizedTextbox" />
The CSS:
.resizedTextbox {width: 100px; height: 20px}
Keep in mind that text box size is a "victim" of the W3C box model. What I mean by victim is that the height and width of a text box is the sum of the height/width properties assigned above, in addition to the padding height/width, and the border width. For this reason, your text boxes will be slightly different sizes in different browsers depending on the default padding in different browsers. Although different browsers tend to define different padding to text boxes, most reset style sheets don't tend to include <input /> tags in their reset sheets, so this is something to keep in mind.
You can standardize this by defining your own padding. Here is your CSS with specified padding, so the text box looks the same in all browsers:
.resizedTextbox {width: 100px; height: 20px; padding: 1px}
I added 1 pixel padding because some browsers tend to make the text box look too crammed if the padding is 0px. Depending on your design, you may want to add even more padding, but it is highly recommend you define the padding yourself, otherwise you'll be leaving it up to different browsers to decide for themselves. For even more consistency across browsers, you should also define the border yourself.
input[type="text"]
{
width:200px
}
Your textbox code:
<input type="text" class="textboxclass" />
Your CSS code:
input[type="text"] {
height: 10px;
width: 80px;
}
or
.textboxclass {
height: 10px;
width: 80px;
}
So, first you select your element with attributes (look at first example) or classes(look last example). Later, you assign height and width values to your element.
This works for me in IE 10 and FF 23
<input type="text" size="100" />
If you don't want to use the class method you can use parent-child method to make changes in the text box.
For eg. I've made a form in my form div.
HTML Code:
<div class="form">
<textarea name="message" rows="10" cols="30" >Describe your project in detail.</textarea>
</div>
Now CSS code will be like:
.form textarea {
height: 220px;
width: 342px;
}
Problem solved.
Lookout! The width attribute is clipped by the max-width attribute.
So I used....
<form method="post" style="width:1200px">
<h4 style="width:1200px">URI <input type="text" name="srcURI" id="srcURI" value="#m.SrcURI" style="width:600px;max-width:600px"/></h4>
You can make the dependent input width versus container width.
.container {
width: 360px;
}
.container input {
width: 100%;
}
Try:
input[type="text"]{
padding:10px 0;}
This is way it remains independent of what textsize has been set for the textbox. You are increasing the height using padding instead
Elements can be sized with the height and width attributes.

Ie6 and Ie7 XHTML strict input form controls have massive padding

I'm using submit controls in my web page
<input type="submit" name="BtnSearch" value="Search" id="btnSearch" title="Search" />
Even when I turn off CSS I get a big gap before the start and after the end of the text of my button. My buttons are also bigger than I want. Is there a way to style buttons in IE6 and 7 to make them more compact?
Set overflow to visible:
input {
overflow: visible;
}
And then set the padding to whatever you want it to be.
Most of the browser-specific styling is done with the border--set border-width to 0 if you want a plain square button.
You could try to style like so:
input [type="submit"] {
padding: 0;
border: 0;
}
or simply add a class to your button and add style rules for that class.
