firefox absolute positioning problem - css

I am having trouble rendering this correctly in firefox. It renders nicely in chrome and in safari.
<div style="" id="login_inline">
<form accept-charset="utf-8" action="/users/login" method="post" id="UserLoginForm">
<div style="display:none;">
<input type="hidden" value="POST" name="_method">
</div>
<input type="text" id="UserDummyEmail" tabindex="1" value="Email" name="data[User][dummyEmail]" style="display: block;">
<input type="text" id="UserDummyPassword" tabindex="2" value="Password" name="data[User][dummyPassword]" style="display: block;">
<input type="text" id="UserEmail" maxlength="255" tabindex="3" name="data[User][email]">
<input type="password" id="UserPassword" tabindex="4" name="data[User][password]">
<div class="submit">
<input type="submit" value="Login">
</div>
</form>
</div>
CSS:
#login_inline {
position:absolute;
right:10px;
top:30px;
width:420px;
}
.submit {
display:inline;
position:absolute;
left:360px;
}
#UserPassword {
position:absolute;
left: 185px;
}
#UserDummyPassword {
position:absolute;
left:185px;
z-index:1;
color:gray;
}
#UserDummyEmail {
position:absolute;
left:10px;
z-index:1;
color:gray;
}
#UserEmail {
position:absolute;
left:10px;
}

EDIT: Live example (Correct rendering)

By positioning absolute you become dependent on correct width of the input elements. This is difficult to do cross-browser because browsers tend to use custom or native elements that don't style consistently. You're better off with an inline-block or floated layout that handles inconsistent width.
If you really have to do it that way there are some hacks using css3 box-sizing property and/or manually tuning properties like line-height and font size and padding to get all browsers to agree on input sizing but that's harder than it sounds.
This question has some info on box-sizing and using percentage/auto width to get consistency: input with display:block is not a block, why not?
EDIT: Based on your comment above you may need to set up some div wrappers to set the size/position of both the hidden and visible elements and then use percentage widths and box-sizing as explained.
<div class="input_wrapper" style="width:100px;position:relative">
<input style="width:100%;box-sizing:border-box;position:absolute">
<div class="fake_input" style="width:100%;position:absolute">
</div>
The key to it all is that box-sizing:border-box is less susceptible to browser differences in padding and border calculations on form inputs.

I found it that usually it is good to put a font-size on input fields, this will make the size of them (more) consistent

add-on height is not adjusting while joining with input box

I am using input group add-on at the front of the input box. While fixing it, the height of the add-on is getting little higher than the box. How to fix the addon to the size of input box?-
<div class="form-group">
<div class="input-group">
<div class="input-group-addon">
<i class="icon-home"></i>
</div>
<input class="form-control" type="text" placeholder=" ">
</div>
</div>
The default image used for the addon is having a bigger height. So, to match it with the input box I have changed the same image into an appropriate size.
Use this image in its place http://i.imgur.com/sCrdOXO.png
Check the FIDDLE
Work with the code in the following way:
.icon-home {
background:url('http://i.imgur.com/sCrdOXO.png') no-repeat;
width:23px;
height:22px;
display:block;
}
.input-group-addon {
display:block;
float:left;
}
#input_css {
display: inline;
margin-top:0px;
}
Hope this answers your question

Perfect 100% width of parent container for a Bootstrap input?

How do I make a Bootstrap input field be exactly 100% as wide as its parent?
As steve-obrien wrote in Bootstrap Issue #1058:
Setting to 100% does not work when applied directly to an input field as it does not take in to account the padding. So you end up with 100% of the container plus the padding on the input box, so the input box usually breaks outside its container.
That ticket offers various solutions, but I'm looking for the best way to do it -- preferably a CSS class already provided by Bootstrap.
Applying the input-block-level class works great for me, across various screen widths. It is defined by Bootstrap in mixins.less as follows:
// Block level inputs
.input-block-level {
display: block;
width: 100%;
min-height: 28px; // Make inputs at least the height of their button counterpart
.box-sizing(border-box); // Makes inputs behave like true block-level elements
}
This is very similar to the style suggested by 'assembler' in his comment on issue #1058.
Just add box-sizing:
input[type="text"] {
box-sizing: border-box;
}
If you're using C# ASP.NET MVC's default template you may find that site.css overrides some of Bootstraps styles. If you want to use Bootstrap, as I did, having M$ override this (without your knowledge) can be a source of great frustration! Feel free to remove any of the unwanted styles...
/* Set width on the form input elements since they're 100% wide by default */
input,
select,
textarea {
max-width: 280px;
}
For anyone Googling this, one suggestion is to remove all the input-group class instances. Worked for me in a similar situation. Original code:
<form>
<div class="bs-callout">
<div class="row">
<div class="col-md-4">
<div class="form-group">
<div class="input-group">
<input type="text" class="form-control" name="time" placeholder="Time">
</div>
</div>
</div>
<div class="col-md-8">
<div class="form-group">
<div class="input-group">
<select name="dtarea" class="form-control">
<option value="1">Option value 1</option>
</select>
</div>
</div>
</div>
</div>
<div class="row">
<div class="input-group">
<input type="text" name="reason" class="form-control" placeholder="Reason">
</div>
</div>
</div>
</form>
New code:
<form>
<div class="bs-callout">
<div class="row">
<div class="col-md-4">
<div class="form-group">
<input type="text" class="form-control" name="time" placeholder="Time">
</div>
</div>
<div class="col-md-8">
<div class="form-group">
<select name="dtarea" class="form-control">
<option value="1">Option value 1</option>
</select>
</div>
</div>
</div>
<div class="row">
<input type="text" name="reason" class="form-control" placeholder="Reason">
</div>
</div>
</form>
I found a solution that worked in my case:
<input class="form-control" style="min-width: 100%!important;" type="text" />
You only need to override the min-width set 100% and important and the result is this one:
If you don't apply it, you will always get this:
In order to get the desired result, you must set "box-sizing: border-box" vs. the default which is "box-sizing: content-box". This is precisely the issue you are referring to (From MDN):
content-box
This is the initial and default value as specified by the CSS standard. The width and height properties are measured including only the content, but not the padding, border or margin.
border-box
The width and height properties include the content, the padding and border, but not the margin."
Reference: https://developer.mozilla.org/en-US/docs/Web/CSS/box-sizing
Compatibility for this CSS is good.
Use .container-fluid, if you want to full-width as parent, spanning the entire width of your viewport.
What about?
input[type="text"] {
max-width:none;
}
Checking that some css file is causing problems. By default bootstrap displays over the entire width. For instance in MVC directory Content is site.css and there is a definition constraining width.
input,select,textarea {
max-width: 280px;}
just add:
width: 100% !important;

I face differences on IE and chrome

I face some layout differences in IE and in Chrome. I have searched Stack overflow high and low for solutions and tried some of it... I tried setting box-sizing to initial...it did not work...there fore tried setting height of the text box it did work but still a big differences. I also tried changing doctype to strict. I encounter this problem as part of my project.
The Problem:
I have form in a div tag. In the form there are 4 rows of text field. I put the preview on IE and the preview on Chrome side by side to compare and realise that it is the spacing between the text area that causes the differences in height.
The Code on my html file:
<div class="leftdetails">
<form class="form2" name="form2" method="post" action="">
<label for="fname">First Name: </label>
<input type="text" name="fname" id="fname" class="regfields"/>
<br />
<label for="cdsid">CDSID: </label>
<input type="text" name="cdsid" id="cdsid" class="regfields"/>
<br />
<label for="mail">Mail Drop: </label>
<input type="text" name="mail" id="mail" class="regfields"/>
<br />
<label for="dateofbirth">D.O.B.: </label>
<input type="text" name="dateofbirth" id="dateofbirth" class="regfields"/>
<br />
</form>
</div>
The code on my CSS (external)
.leftdetails
{
font-family:Myriad Pro;
font-size:18px;
float:left;
width:50%;
text-align:center;
}
.regfields
{
width:200px;
height:20px;
vertical-align:bottom;
}
.form2
{
text-align:right;
margin-right:50px;
}
This is not published online yet therefore there is not link...but I will be glad to provide screenshot. Its a very minor difference but I just want to understand why.
Try to set the padding-top and padding-bottom to 0px in the regfields CSS class. Maybe also margin-top and margin-bottom
Try using a conditional IE statement in your CSS to target only the Internet Explorer browser.
If you don't know how to do so, examples can be found here

Blur effect on the entire webpage

I want that the unregistered users on my website, see the entire website's pages with a blur effect.
How can I create this blur effect with css ?
Try this...
body {
filter:blur(3px);
}
You'll need to add -moz-, -webkit- prefixes (or use something like PrefixFree)
Here's some results, if by blur you mean fuzziness:
This guy uses image shifting and opacity techniques in combo, I know your users are looking at a blurred website, but if there's no easy solution then perhaps taking a snapshot of your rego page and overlaying the image then it might do:
http://web.archive.org/web/20120211000759/http://simurai.com/post/716453142/css3-image-blur
If you wanted to attempt duplicating your rego page, given that it may be a) disabled and b) minimal, then perhaps you could even have a bash at using the above image technique and applying it to node sets, offsetting the copies with CSS positioning and opacity - idk if zoom might help you too there. Even if your page was minimal enough, this would obviously require Javascript to duplicate the nodes, unless your backend can do this node duplication. Just an idea, really. Here's a really awful, very quick example:
http://jsfiddle.net/9qnsz/2/
This SO posts outlines some of the limitations and difficulties with gaussian blur when not done with image, and has some interesting links:

Edit (2015): The filter css property is forming tantalisingly complete coverage. This lets you write rules like body { filter: blur(10px); }, which blurs the entire page.
From what I can tell, there's no cross-browser way of blurring an element, even in this "modern age" of html5, css3, etc...
There is a blur filter for IE (and only IE). An svg blur filter can also be applied to an html element but from what I can tell, it only works in Firefox.
If you're happy for browser-specific hacks, go ahead, but if you need the effect to work on all browsers you're outta luck.
If you just want to blur text, you can use a clever text-shadow trick:
.blurry {
color: transparent;
text-shadow: 0 0 3px black; /* set to colour you want */
}
There are also ways to blur images, either by overlaying transparent, shifted copies of the image, or by processing the data with javascript.
Perhaps you can cobble together these techniques, and it will achieve what you want.
But the broad answer, regrettably, for the moment is: there is no easy, holistic way to blur stuff in HTML.
(I thought we were living in the future, man? What gives?!)
Addendum: Hope is in sight. At the time of writing, some webkit nightly ("bleeding edge") builds are implementing some of the new css filter specification. That demo doesn't work on any webkit browser I have installed, so it's still far from mainstream yet.
You can add a fixed div set to 100% width and height to your body. That will fill the screen and you can put either a semi-transparent background on it or use CSS3 to create the effect you are looking for.
Create a new div tag with id="body_bag" and put your rest of the site edits within that div and use following css to give the blur effect.
#body_bag {
position: absolute;
width: 100%;
top: 0;
left: 0;
background: #000;
opacity: 0.5;
filter: alpha(opacity = 50); /* required for opacity to work in IE */
}

Replace input type=file by an image

Like a lot of people, I'd like to customize the ugly input type=file, and I know that it can't be done without some hacks and/or javascript. But, the thing is that in my case the upload file buttons are just for uploading images (jpeg|jpg|png|gif), so I was wondering if I could use a "clickable" image which would act exactly as an input type file (show the dialog box, and same $_FILE on submitted page).
I found some workaround here, and this interesting one too (but does not work on Chrome =/).
What do you guys do when you want to add some style to your file buttons? If you have any point of view about it, just hit the answer button ;)
This works really well for me:
.image-upload>input {
display: none;
}
<div class="image-upload">
<label for="file-input">
<img src="https://icons.iconarchive.com/icons/dtafalonso/android-lollipop/128/Downloads-icon.png"/>
</label>
<input id="file-input" type="file" />
</div>
Basically the for attribute of the label makes it so that clicking the label is the same as clicking the specified input.
Also, the display property set to none makes it so that the file input isn't rendered at all, hiding it nice and clean.
Tested in Chrome but according to the web should work on all major browsers. :)
EDIT:
Added JSFiddle here: https://jsfiddle.net/c5s42vdz/
Actually it can be done in pure css and it's pretty easy...
HTML Code
<label class="filebutton">
Browse For File!
<span><input type="file" id="myfile" name="myfile"></span>
</label>
CSS Styles
label.filebutton {
width:120px;
height:40px;
overflow:hidden;
position:relative;
background-color:#ccc;
}
label span input {
z-index: 999;
line-height: 0;
font-size: 50px;
position: absolute;
top: -2px;
left: -700px;
opacity: 0;
filter: alpha(opacity = 0);
-ms-filter: "alpha(opacity=0)";
cursor: pointer;
_cursor: hand;
margin: 0;
padding:0;
}
The idea is to position the input absolutely inside your label. set the font size of the input to something large, which will increase the size of the "browse" button. It then takes some trial and error using the negative left / top properties to position the input browse button behind your label.
When positioning the button, set the alpha to 1. When you've finished set it back to 0 (so you can see what you're doing!)
Make sure you test across browsers because they'll all render the input button a slightly different size.
Great solution by #hardsetting,
But I made some improvements to make it work with Safari(5.1.7) in windows
.image-upload > input {
visibility:hidden;
width:0;
height:0
}
<div class="image-upload">
<label for="file-input">
<img src="https://via.placeholder.com/300x300.png?text=UPLOAD" style="pointer-events: none"/>
</label>
<input id="file-input" type="file" />
</div>
I have used visibility: hidden, width:0 instead of display: none for safari issue and added pointer-events: none in img tag to make it working if input file type tag is in FORM tag.
Seems working for me in all major browsers.
Hope it helps someone.
A much better way than writing JS is to use native,
and it turns to be lighter than what was suggested:
<label>
<img src="my-image.png">
<input type="file" name="myfile" style="display:none">
</label>
This way the label is automatically connected to the input that is hidden.
Clicking on the label is like clicking on the field.
You can replace image automatically with newly selected image.
<div class="image-upload">
<label for="file-input">
<img id="previewImg" src="https://icon-library.net/images/upload-photo-icon/upload-photo-icon-21.jpg" style="width: 100px; height: 100px;" />
</label>
<input id="file-input" type="file" onchange="previewFile(this);" style="display: none;" />
</div>
<script>
function previewFile(input){
var file = $("input[type=file]").get(0).files[0];
if(file){
var reader = new FileReader();
reader.onload = function(){
$("#previewImg").attr("src", reader.result);
}
reader.readAsDataURL(file);
}
}
</script>
I would use SWFUpload or Uploadify. They need Flash but do everything you want without troubles.
Any <input type="file"> based workaround that tries to trigger the "open file" dialog by means other than clicking on the actual control could be removed from browsers for security reasons at any time. (I think in the current versions of FF and IE, it is not possible any more to trigger that event programmatically.)
This is my method if i got your point
HTML
<label for="FileInput">
<img src="tools/img/upload2.png" style="cursor:pointer" onmouseover="this.src='tools/img/upload.png'" onmouseout="this.src='tools/img/upload2.png'" alt="Injaz Msila" style="float:right;margin:7px" />
</label>
<form action="upload.php">
<input type="file" id="FileInput" style="cursor: pointer; display: none"/>
<input type="submit" id="Up" style="display: none;" />
</form>
jQuery
<script type="text/javascript">
$( "#FileInput" ).change(function() {
$( "#Up" ).click();
});
</script>
I have had lots of issues with hidden and not visible inputs over the past decade sometimes things are way simpler than we think.
I have had a little wish with IE 5,6,7,8 and 9 for not supporting the opacity and thus the file input would cover the upload image however the following css code has resolved the issue.
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: alpha(opacity=0);
The following snipped is tested on chrome, IE 5,6,7,8,9,10 the only issue in IE 5 is that it does not support auto margin.
Run the snippet simply copy and paste the CSS and HTML modify the size as you like.
.file-upload{
height:100px;
width:100px;
margin:40px auto;
border:1px solid #f0c0d0;
border-radius:100px;
overflow:hidden;
position:relative;
}
.file-upload input{
position:absolute;
height:400px;
width:400px;
left:-200px;
top:-200px;
background:transparent;
opacity:0;
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: alpha(opacity=0);
}
.file-upload img{
height:70px;
width:70px;
margin:15px;
}
<div class="file-upload">
<!--place upload image/icon first !-->
<img src="https://i.stack.imgur.com/dy62M.png" />
<!--place input file last !-->
<input type="file" name="somename" />
</div>
its really simple you can try this:
$("#image id").click(function(){
$("#input id").click();
});
You can put an image instead, and do it like this:
HTML:
<img src="/images/uploadButton.png" id="upfile1" style="cursor:pointer" />
<input type="file" id="file1" name="file1" style="display:none" />
JQuery:
$("#upfile1").click(function () {
$("#file1").trigger('click');
});
CAVEAT:
In IE9 and IE10 if you trigger the onclick in a file input via javascript the form gets flagged as 'dangerous' and cannot be submmited with javascript, no sure if it can be submitted traditionaly.
The input itself is hidden with CSS visibility:hidden.
Then you can have whatever element you whish - anchor or image.., when the anchor/image is clicked, trigger a click on the hidden input field - the dialog box for selecting a file will appear.
EDIT: Actually it works in Chrome and Safari, I just noticed that is not the case in FF4Beta
Working Code:
just hide input part and do like this.
<div class="ImageUpload">
<label for="FileInput">
<img src="../../img/Upload_Panel.png" style="width: 18px; margin-top: -316px; margin-left: 900px;"/>
</label>
<input id="FileInput" type="file" onchange="readURL(this,'Picture')" style="cursor: pointer; display: none"/>
</div>
form input[type="file"] {
display: none;
}
