I'm trying to create a border inside an image instead of outside of the image. I want to do this because I would like to put some alpha value on the border so that i can see the image through the border.
I tried placing a div a few pixels smaller than the image around the image and then setting "overflow:none". The border is now inside the image, but when i apply alpha to the border nothing can be seen through the border because overflow is set to none.
On the other hand. If i don't set "overflow", then the border won't show up.
I want something like this:
Tested in firefox and ie8 (no opacity yet in ie8, but you can use a filter for that):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>test</title>
<style type="text/css">
.imgcontainer{padding:0; position: relative;
display: inline-block; overflow: hidden;}
.imgcontainer img{display:block;}
.borders, .borders2{position: absolute; width:100%; height:100%;
border: 4px solid #000;}
.borders{opacity: .5;}
.borders2{bottom: 4px; right: 4px;}
</style>
</head>
<body>
<div class="imgcontainer">
<div class="borders"><div class="borders2"></div></div>
<img src="img" />
</div>
</body>
</html>
This creates a 4px transparent border, but that can easily be changed.
Because the opacity only affects the absolute positioned divs the image doesnot become transparent. Two border-divs are needed in this example because this way the image size is variable, if your images always have the same size you could do this with only one.

You can use a wrapper with negative margins and rgba(255,255,255,.5) as border-color.

I'm developing chrome extension, I want to make border radius and use radius border propery in css, but it boder in child elemement.
My code html here :
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" style="border-radius:10px">
<head>
</head>
<body>
content here
</body>
</html>
I want border as picture below :
http://postimg.org/image/8ct4dcq93/
Unfortunately, I don't think you can do it.
The frame around the popup page (highlighted in red in a graphics editor) is fully controlled by Chrome:
You can't change its shape / color, just like you can't change normal Chrome chrome (pun intended).
There is one to make the popup.html border-radius that to add another Div container to popup HTML, set the body background to none and give the background color to the div container. After that, you can give the radius to the container.
e.g
body {
background: none
}
.container {
background: green;
border-radius: 10px;
width: 50%;
height: 100px;
text-align: center;
}
<body>
<div class="container">
The content is here....
</div>
</body>
Your supposed to style the html tag, not the body tag.
html {
border: 5px solid rgb(200, 200, 200);
}
<!DOCTYPE html>
<html>
<header>
<link rel="stylesheet" href="popup.css">
</header>
<body>
<h1>Hello World!</h1>
<script src="popup.js"></script>
</body>
</html>
Consider the webpage below. The <img> is positioned absolutely relative to its parent, and when I load this page on Safari or Firefox, the <img> appears in the top-right, as expected (see first image). However, when the border is removed from from the <div>, for example, by setting border-width: 0, the <img> positions itself absolutely relative to the <p> tag, its sibling! See picture #2. Why is this? What difference should the border make?
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<style type="text/css">
body {
margin: 0;
}
div {
position: relative;
left: 0;
top: 0;
border: 1px solid red;
}
img {
position: absolute;
right: 0;
top: 0;
}
p {
margin: 20px;
}
</style>
</head>
<body>
<div>
<img src="content/en/flag.png" />
<p>This is a test</p>
</div>
</body>
</html>
Your image is always at the top-right. It has to do with collapsing margins.
Try to do it with a background color. You will see that your div is moving away from the top of the body a few pixels. If you delete p's margin everything would be fine, or setting p as an inline element or floating it, or even setting an overflow to auto, hidden or scroll to the parent. Another way to fight the collapsed margin is to add a border to the container element. So you really was solving this with that border.
But image is always where it is supposed to be.
Its really strange indeed but let me try to explain this actually the elements are not float and you are using margin on p tag which the div is taking properly when it has border and failed to implement it when its removed if add float property than the div will also gain its height
add overflow:auto; to div it will fix the problem

I want my button div to be placed horizontally inside the confirm div: example.
Right now my dialog-button div width is equal to the width of the confirm Div. Why?
I am just placing two buttons inside my Div, so it's width should be equal to 128 (the total of two button witdh). Similarly the height should be equal to button height, but it isn't.
Second i want that mt button-div placed center horizontally . I tried left: 50% inside my button-div. But it is aligning the left margin with the centre of the confirm div. How can i do it?
EDIT
--------------------------------------------------
May be I didn't understand correctly, but if you want it inside then put it inside.
<div id="message">
Are you sure you want to
<div id="dialog-button">
<button>Ok</button>
<button>Cancel</button>
</div>
</div>
Demo
Update 1
Right now my dialog-button div width is equal to the width of the confirm Div. Why?
Why, because <div>s are block tag, they always take 100% width of the containing element. It is not equal to the width of confirm Div.
To make the dialog-button take the actual width use display: inline-block as its CSS. Demo
Update 2:
To the best from what i understood. This is what you want. If not help me help you.
Update 3:
Ok, here is a demo with the image. I will leave the without image part to you. ;)
The div which the two buttons are in is actually the width of the of the comfirm div. The reasons why divs stretch to the width of their parent, is because that is block level element.
the reason every thing seems so confusing is that you have a lot left floating divs in your example. These are changing how things would normally laid out. To make things simpler why dont you try removing some of the more confusing elements. I suggest trying a more simple example like the one below:
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link rel="stylesheet" href="css/ie-css3.htc" type="text/css">
<link rel="stylesheet" href="css/messageDialogStyle.css" type="text/css">
<script type="text/javascript" src="js/jquery-1.7.1.js">
</script>
<script type="text/javascript" src="js/jquery-ui-1.8.17.custom.min.js">
</script>
<script type="text/javascript" src="js/puff.js"></script>
<script type="text/javascript" src="js/jquery.dialog.js"></script>
</head>
<body>
<div id="confirm">
<div id="message">
Are you sure you want to
</div>
<div id="dialog-button">
<button>Ok</button>
<button>Cancel</button>
</div>
</div>
</body>
</html>
If you want to center a button. If you change the margin-left and margin-right to auto you will center any block element. try changing your css to the css below:
#confirm {
background-color: #ddd;
display:block;
width:400px;
min-height:120px;
position:absolute;
border:1px solid #ccc;
border-radius: 15px;
-moz-border-radius: 15px; /*FireFox*/
-webkit-border-radius: 15px; /*Opera, safari*/
behavior: url(css/border-radius.htc); /*IE*/
}
#message {
width: 280px;
border:1px solid #ccc;
white-space: normal;
word-wrap: break-word;
margin:20px 0 0 0;
overflow: hidden;
}
#dialog-button {
border:1px solid #ccc;
position: relative;
}
button {
display:block;
margin-left:auto;
margin-right:auto;
width: 64px;
}
Note if you have to make the button a block element for the margin auto trick to work.
You can find more about block level element here.
I am trying to replace div elements with button elements to improve accessibility, but I need the buttons to layout like the divs used to do. (note this only needs to work in webkit)
The div takes the width of the parent container, while the button only takes the place needed to display its content.
How can I change that?
I would not like to set something like width: 100%, because if you are using more then one button in a container with display: webkit-box the divs nicely layout to use remaining space.
Here is a small example:
<!DOCTYPE html>
<html>
<head>
<title>button test</title>
<style>
.mybutton{
display: block;
border: 1px solid red;
-webkit-appearance: none;
-webkit-border-radius: 6px;
background-color: transparent;
-webkit-gradient(linear,left bottom,left top,color-stop(0, #A8ACB9),color-stop(1, #eee));
text-align: center;
}
</style>
</head>
<body>
<div class="mybutton">Div Button</div>
<button class="mybutton">Button</button>
</body>
</html>
If your button is in a container with "display: -webkit-box" then just add "-webkit-box-flex: 1" to the button (or any elements) within that container. This solves it.

I'm not sure why you have backward slashes on your -webkit rules. Remove them and they will behave the same as divs, except for some inherited styles that need to be resetted.
You can see an example of buttons and inputs playing nicely with webkit box here:
http://jsfiddle.net/dt592/
Maybe you should go more specific. Try button.mybutton { in your css...
Consider the next code:
#container {
width:500px;
}
#inside {
padding:10px;
width:100%;
}
If I choose width:100%; will it be the same as stating "width 480:px" (that is, calculating the padding already) or will it be as "width:500px"
Thanks
Joel
It will be like width:500px and adding the padding it will push the insides of overflow the #container..
But if #inside is a block element, then just giving the padding will make it behave as if it were width:480px
Example at http://www.jsfiddle.net/uA9LV/
It will be the same width as the parent container provided it's a block level element. So #inside will be 500px wide with 10px of padding on every side.
I put this in a sample document and the container div only resized 3 sides (left, top, and bottom).. and the inside div pushed it's boundaries outside of the container by 20px to the right.
I tested in IE8, Firefox 3.6.10, and the latest Chrome. Using various doctypes had no effect.
The code I used was:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Untitled</title>
<style>
#container {
width:500px;
border: solid 1px blue;
}
#inside {
padding:10px;
width:100%;
border: solid 1px red;
}
</style>
</head>
<body>
<div id="container">
<div id="inside">
Hello World!
</div>
</div>
</body>
</html>
Note: if you remove the Width declaration from the #inside div then you'll get exactly what you want. Which is an inner div that is 480px in width + 10px on each side for padding. See this link for more information on it: Solving the CSS Padding problem.
