I am just using a simple CSS code for this:
button {
border: 1px dotted #bebebe;
background: #eeeeee;
font-size: 20px;
color: black;
padding: 7px;
border-radius: 4px;
}
But the dotted border doesn't show up in the left side:
What am I doing wrong?
EDIT:
Well, for everyone who has this problem, it is about the navigator you're using and zoom. I don't know why but some buttons you can see the border in all sides, and some buttons you can't.
There are bugs in browsers in rendering one pixel wide dotted borders, see e.g. the Mozilla bug report Dotted/dashed border-radiused corners are rendered as solid and the Chromium bug report Another Border-Bug: dotted line turns solid on the half way. You seem to have triggered one of such bugs in Chrome. Testing your jdsfiddle in Chrome 28beta on Win 7, I can see the left border as solid and the bottom border solid in the left half. (This is a bit difficult to see but it becomes more visible if you take a screenshot and zoom it or set the border color to red, for example.)
I’m afraid it might be difficult to find an acceptable workaround. In this particular case, the bug seems to disappear if you remove the rounding of corners (which you probably don’t want to do) or set the border width to 2px.
A dotted 1px border is very hard to see. If you zoom in Cntrl + + I think you'll see that there is actually a dotted border.
Alternatively, changing 1px to 2px : border: 2px dotted #bebebe; also shows that the border is present.
EDIT:
Remove the border-radius: 4px; and you'll see the dotted border.

I'm using CSS box-shadow to mimic a background that "bleeds" to the edges of the browser window. It works great in Chrome, Firefox, Safari, and Internet Explorer 9 & 10. However, Internet Explorer 11 renders a transparent 1px "space" before the left (negative) box-shadow.
Take this HTML:
<div class="wrapper">
<div class="widget">Test</div>
</div>
And this CSS:
.wrapper {
background:red;
padding:20px 0;
}
.widget {
width:600px;
height:400px;
margin:0 auto;
text-align:center;
background:white;
box-shadow:20em 0 0 0 white, -20em 0 0 0 white;
}
In most browsers, the widget DIV has a white background and white left & right box shadows that fill the width of the browser window with no spaces, breaks or red from the wrapper bleeding through. In IE11 there is a 1px red line that runs vertically along the left side of the widget DIV.
Take a look at this fiddle for an example: http://jsfiddle.net/Bxsdd/. (You may need to manually adjust the width of the fiddle Results pane as slight differences in the width of the window show the issue more apparently - again, only in IE11.)
Things I've tried to remove the transparent space:
Changing the box-shadow from using em's to using px's
Adding or subtracting 1px from the other box-shadow attributes
Adding a border around the widget DIV
Adjusting the padding, display, position and other CSS elements for the widget
So many things I can't even remember right now
Any ideas how to remove the 1px transparent space in IE11?
Now that we know it's a bug, here's one acceptable workaround:
.widget {
width:600px;
height:400px;
margin:0 auto;
text-align:center;
background:white;
box-shadow:20em 0 0 0 white, -20em 0 0 0 white;
position:relative;
z-index:2;
}
.widget:before, .widget:after {
position:absolute;
content: " ";
width:1em;
left:-1em;
top:0;
height:100%;
background:white;
z-index:1;
}
.widget:after {
left:auto;
right:-1em;
}
Basically, I'm adding absolutely positioned :before & :after pseudo elements that contain nothing more than the same background color as the widget DIV and that DIV's box-shadow. These pseudo elements are offset just to the outside-left and outside-right of the widget DIV and positioned behind it so that they provide the correct color for the box-shadow bleed through.
Obviously this adds complication if one is already using the :before & :after elements, but this works for my purposes. I suppose one could also try setting negative margins on the widget DIV.

THE PROBLEM:
This appears to be an graduated alpha transparency/aliasing issue to do with even/odd pixelation calculations.
As best I can tell, colour is spilling into that pixel line but the antialiasing calculation is stripping its alpha value in an attempt to try graduate the distinction of the box-shadow with its surrounds.
That is fine on the outside border of the box shadow, but not so great in the inside border - which is why we are all here!
WHAT (PRETTY MUCH) WORKED FOR ME (PURE CSS):
In my use case, this was fixed by adding several additional box-shadows (of different and lesser values) like so:
div {box-shadow: 10px 0px 0px 0px red,
4px 0px 0px 0px red,
3px 0px 0px 0px red,
1px 0px 0px 0px red;}
Though not elegant, this cumulatively increase the "spill" into the inner pixel line. About three additional box-shadows were required to achieve the desired value - suggesting the antialiasing spill is set at about 25%. Different device densities may change that?
Simply repeating the same box-shadow didn't work - so I am guessing IE treated them as an repetition error and ignored them.
THE "PRETTY MUCH" PART (FOR ME):
In my use case I was adding a purely horizontal box shadow to the right of a text span to create the impression of padding if the line broke and became more than one line. I wasn't adding a shadow to the top or bottom or around a div.
The "pretty much" part for me is that there is a little vertical spill "dot" of about 1px or 2 pixels at the top and bottom of pixel line at certain widths. Essentially, the same problem above in reverse.
Not ideal, but far more preferable than having a whole line transparent.
I hope this will work for you (the reader) in similar other scenarios, but I haven't tested this.
Good luck, and let's all thank good ol' IE for its "challenges"!! ;)
You can fill the space with outline:1px solid color; It worked for me.
.container{
display:block;
position: relative;
width:450px;
height:450px;
margin: 0 auto;
background-color: #654d7f;
}
.header-emphasis{
position: absolute;
bottom:5px;
max-width: 420px
}
span{
position: relative;
left:8px;
background-color: white;
padding:4px 4px 4px 0px;
color: #666666;
box-shadow: 6px 1px 0px 2px #ffffff, -8px 1px 0px 2px #ffffff;
outline: 1px solid white;
}
<div class="container">
<h3 class="header-emphasis">
<span class="highlight">
If there are no dogs in heaven then when i die i want to go where they went.
</span>

</div>
I thought I would share my answer to this issue. I cannot be sure that I have had the same exact problem as everyone else, but what I have observed is this: The problem occurs in EI11 (and EI10 according to other which I have not tested) when an element with a set width of pixels is centered using margin: auto; (my case was a left/right issue). I noticed that on resize, the div would shift over to the right 1px on every other pixel width of the screen.
I used a transparent background to observe that instead of just a gap appearing on the left, the div did in fact shift 1px to the right.
Changing the width of the div 1px does work on the current screen width. However, change the screen width will bring back the problem on every other pixel.
To solve the issue, we need to identify the screen width as even or odd. In my case, on even I added a css rule to my culprit div. The new rule changes the left positioning by 0.5px.
Furthermore, the function needs to be executed on the screen resize.
Below is the script I used to fix the issue:
(function (window, document) {
function isEven() {
var windowWidth = window.innerWidth;
// Find out if size is even or odd
if (windowWidth % 2 === 0) {
document.querySelector("#container").classList.add("container_left_1px");
} else {
document.querySelector("#container").classList.remove("container_left_1px");
}
};
document.addEventListener("DOMContentLoaded", isEven);
window.addEventListener(('onorientationchange' in window) ? 'orientationchange':'resize', isEven);
})(this, this.document);
And the css rule
.container_left_1px {left: .5px;}
Executing the script only on EI10 and 11 would be optimum. Please forgive my scripting as this is the first js I have made. Please feel free to correct any issues. This solved my problem; I hope someone finds it helpful!
DaveE gave a nice solution. I played with this myself as well. I had an issue with the top and bottom blur of a box-shadow, instead of left and right. I eventually solved it by just adding a border on top and use important next to it.
.class
{
border-top:1px solid $colorBg !important;
border-bottom:1px solid $colorBg !important;
}
Perhaps not as well tought out as the previous solution, but it worked for me.
Found this solution(Small space between box shadow and div when alpha set) and it works for me: div width must be an odd number.
width: 800px; => not working, but width:799px; => works and white gap disappeared!
In my case, I had a white line between the div bottom and the shadow and I resolved the issue adding a height to the div with decimals:
height:30px; -> height:30.1px;
I have this piece of CSS:
.ab-banner
{
background-color: #212121;
background-image: url(logo.png);
background-repeat: no-repeat;
width: 100%;
height: 45px;
text-align: right;
border-bottom: 2px solid #4DD2FF;
}
which produces:
Adding this: box-shadow: 0px 2px 2px 0px #000;
produces this:
If you look closely at the shadow, it starts in the middle of the border. Increasing the border thickness causes the same behavior, so its not started at the layer's bottom.
How can I get the shadow to start from the bottom of the border?
I saw that you can do this by setting the border as a background image as done here, but is there no way to do this in CSS? I can get around this by making the shadow larger, though, that is not what my design calls for.
This is what I'd like:
EDIT:
#StackOverFlow UI, you are right, this will work correctly. Thank you for the example! The reason why the shadow was appearing in the middle was because the style was applied both to the table itself as well as the row that it contained. Removing that style class reference from one or the other would fix the issue. This unearthed a deeper issue in the layout, beyond the scope of this question. Accepting your answer as it is relevant.
What you have seems to be fine. Check this out, it is just that the shadow is deeper near the borders.By increasing the box-shadow property to a higher value, you can get what you want. http://liveweave.com/DkpyhE
It seems that when you have an element with different sized/colored borders, you can see a very strange jagged line happening. I never noticed this before, but was looking at Vimeo's super hot new design when I noticed this (don't really want to say "glitch") weird occurrence.
So if you had a div hanging out, styled as in below, you'll notice a pixel stepping (almost like it's set to inset, rather than solid...)
div {
height : 25px;
width : 50px;
background : #eee;
border-style : solid;
border-color : green;
border-left-color : black;
border-width : 3px 3px 3px 15px;
}
Anyone notice this/ know why it happens?
The reason this happens is because it's creating a 'frame' around the box.
Think of a wooden picture frame, you don't use four rectangular pieces of wood to create a frame, you use 4 trapezoidal pieces and put them together. When you set a larger width on one side, its diagonally rendering it inward towards the corner of the box.
The reason it looks bad is because the antialiasing between borders has never been good.
Alternative
You could just do div:before{border-left: 15px solid #000;} if you didn't want the borders cropped like that.
That's not a "glitch" - it's how borders work. They connect diagonally.
If you take it one step further and create a <div> with no height and width, but a large border you can see the result - http://jsfiddle.net/mFzrA/
BTW - this is the technique being used to create pure CSS triangles and speech bubbles. You just make 3 of the borders transparent and the 4th gives you a nice triangle.
I just wanted to suggest using box-shadow on the border with bigger border-width to avoid "jagged line".
Works for me, hope it helps :)
div {
height : 25px;
width : 50px;
background : #eee;
border-style : solid;
border-color : green;
border-width : 3px 3px 3px 0px;
box-shadow:-15px 0px black;
}
I'm trying to highlight the row the mouse is over in a table of data. I'm trying to do this with a border-top and border-bottom. To help the readability i also have a light transparent png on alternate rows.
It seems that when I turn on and off the borders (works in IE8+ and FF) the rows jump around a little. I think I can fix it by having a a non-hover transparent border, rather than none at all. Is this x-browser compatible now days?
In Chrome, the highlighted row's border does not go away when you move the mouse off the row, why?
http://justinzaun.com/Tree/people/
Update: I've fixed the border issue in chrome where they wouldn't go away. I moved the border to the TDs rather than the TR. The rows are still jumping around though.
Thanks!
put an transparent border on your normal state elements.
When the :hover is applied the size of the border changes the size the element takes up.
eg:
.myelement
{
border:4px solid transparent;
}
.myelement:hover
{
border: 4px solid green;
}
http://jsfiddle.net/mPmRA/
EDIT:- more specifically to your table (ugh: tables ... collapse border makes the above not work properly)
http://jsfiddle.net/mPmRA/1/
put the transperant border on the tr
tr
{
border-top:4px solid transparent;
border-bottom:4px solid transparent;
}
And for the hover do something like:
tr:hover td
{
border-top:4px solid green;
border-bottom:4px solid green;
}
The td borders will then appear ABOVE the row's border.
An easier way is adding "margin-top:-1px; margin-bottom: -1px;" to the :hover style, this corrects the new height with the border.
Make sure your border is set to the INSIDE instead of the outside. Unfortunetly, the inset option for borders is not yet part of CSS. Here's a bit of CSS to make the borders inside the element using box shadows:
.mytable tr:hover {
-moz-box-shadow: inset 0 0 1px #000;
}
That will make a 1px black border on the INSIDE of your element! :D
I hope this helps, if you're set on a black dotted border, your only option is to set absolute positioning, and position each table row individually, which is a pain in the ass. :/
If you've got relative or static positioning, elements will move when other increase in size. Wulf's idea may work with a little configuring, but to be honest, the box shadow is a much nicer border then the dotted one. (a bit tacky if I say so myself. ^_^ Sorry.)
I am using RGBA to create a transparent background that overlays on top of an image. Works just fine. My questions is this: Is there a way to "soften" the edges of the box to where it flows more into the picture vs a hard edge.
Here is my CSS for the box:
#past{
position:absolute;
left:0;
top:363px;
background-color: rgba(34,34,34,0.6);
/* For IE 5.5 - 7*/
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#99222222, endColorstr=#99222222);
/* For IE 8*/
-ms-filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#99222222, endColorstr=#99222222);
z-index:10;
padding:10px;
}
I know I can do this by creating a background image in Photoshop but I was looking for a CSS only way vs using an image.
Also I would prefer if at all possible for this to work in all browsers.
Thanks for the help. =>
Another option is to use one of my personal favorite CSS tools: box-shadow.
A box shadow is really a drop-shadow on the node. It looks like this:
-moz-box-shadow: 1px 2px 3px rgba(0,0,0,.5);
-webkit-box-shadow: 1px 2px 3px rgba(0,0,0,.5);
box-shadow: 1px 2px 3px rgba(0,0,0,.5);
The arguments are:
1px: Horizontal offset of the effect. Positive numbers shift it right, negative left.
2px: Vertical offset of the effect. Positive numbers shift it down, negative up.
3px: The blur effect. 0 means no blur.
color: The color of the shadow.
So, you could leave your current design, and add a box-shadow like:
box-shadow: 0px -2px 2px rgba(34,34,34,0.6);
This should give you a 'blurry' top-edge.
This website will help with more information: http://css-tricks.com/snippets/css/css-box-shadow/
It depends on what type of fading you are looking for.
But with shadow and rounded corners you can get a nice result. Rounded corners because the bigger the shadow, the weirder it will look in the edges unless you balance it out with rounded corners.

You can use CSS gradient - although there are not consistent across browsers so You would have to code it for every one
Like that: CSS3 Transparency + Gradient
Gradient should be more transparent on top or on top right corner (depending on capabilities)
