How can you remove the weird white space between two nested divs on Chrome.
<div class="bar">
<div class="progress">
</div>
</div>
.bar {
width: 200px;
height: 6px;
border: 1px solid black;
border-radius: 3px;
}
.progress {
height: 100%;
width: 50%;
background: black;
}
Here is the link to the fiddle: http://jsfiddle.net/hfob7yz4/1/.
On Chrome it looks like
this for me with the weird margin.
On Firefox it looks pretty normal like expected:
firefox-img
It also depends on the screen width. The problem only shows up on my laptop.
Thanks
The reason is that there is a border around the main div, and gets visible on some screens
to avoid this add
.bar {
box-sizing: border-box;
}

You are hitting a sort of edge effect when on different zoom levels - there are bits of pixel 'left behind' in the system's calculations as it tries to map part CSS pixels to the several screen pixels that might make up a CSS pixel on modern screens.
Instead of needing a second, inner div, you could paint the progress with a background image using a linear-gradient - this can be altered by JS dynamically as required.
.bar {
--progress: 50%;
width: 200px;
height: 6px;
border: 1px solid black;
border-radius: 3px;
background-image: linear-gradient(to right, black 0 var(--progress), transparent var(--progress) 100%);
}
}
<div class="bar">

I want a border for my entire page on the left and right sides but whenever i try to set the border image it just comes up white, I can change the color without a problem but I want it to be a certain png image only on the left and right sides of the page.
I have already tried all of the border image properties and i have set the border left and right to transparent. I have tried changing my file path too but I know that isn't the issue because I have the same image placed elsewhere.

<div id="margins">
ENTIRE BODY OF PAGE HERE WOULD BE HERE
</div>
#margins {
border-left: 50px solid transparent;
border-right: 50px solid transparent;
border-image-source: url('/images/background.png');
I need the image to show only in the borders but it isn't showing at all and instead it is showing white.
You need to also set a border-image-slice and/or border-image-width, and a border-image-repeat property. Note, border-image-width and border-width are different.
#margins {
border-left: 50px solid transparent;
border-right: 50px solid transparent;
border-image: url('https://picsum.photos/id/237/200/300') 50 round;
}
<div id="margins">
ENTIRE BODY OF PAGE HERE WOULD BE HERE
</div>
Here is an example that uses a background image on the body that can be seen in the margins around other elements. You can set the image to tile, or use a fixed, centered background with background-size cover for a nice effect.
body {
margin: 0 50px 20px;
background: url('https://picsum.photos/id/237/200/300') repeat center;
}
header {
background: white;
min-height: 80px;
margin-bottom: 50px;
}
main {
background: white;
min-height: 200px;
margin-bottom: 50px;
}
footer {
color: white;
}
<header>Nav</header>
<main>Content</main>
<footer>Footer</footer>
As you can see in this picture, I've got an orange div inside a green div with no top border. The orange div has a 30px top margin, but it's also pushing the green div down. Of course, adding a top border will fix the issue, but I need the green div to be top borderless. What could I do?
.body {
border: 1px solid black;
border-top: none;
border-bottom: none;
width: 120px;
height: 112px;
background-color: lightgreen;
}
.body .container {
background-color: orange;
height: 50px;
width: 50%;
margin-top: 30px;
}
<div class="header">Top</div>
<div class="body">
<div class="container">Box</div>
</div>
<div class="foot">Bottom</div>
You could add overflow:auto to .body to prevent margin-collapsing. See http://www.w3.org/TR/CSS2/box.html#collapsing-margins
What you experience is margin collapsing. The margin doesn't specify an area around an element, but rather the minimum distance between elements.
As the green container doesn't have any border or padding, there is nothing to contain the margin of the orange element. The margin is used between the top element and the orange element just as if the green container would have the margin.
Use a padding in the green container instead of a margin on the orange element.
Use padding instead of margin:
.body .container {
...
padding-top: 30px;
}
Not sure if this will work in your case, but I just solved this with the following CSS properties
#element {
padding-top: 1px;
margin-top: -1px;
}
#element was being pushed down because it's first child element had a margin-top: 30px. With this CSS, it now works as expected :) Not sure if it'll work for every case, YMMV.
You can either add padding-top: 30 on the green box, use relative positioning on the orange box with top: 30px, or float the orange box and use the same margin-top: 30px.
You read this document:
Box model - Margin collapsing
CSS
.body {
border: 1px solid black;
border-bottom: none;
border-top: none;
width: 120px;
height: 112px;
background-color: lightgreen;
padding-top: 30px;
}
.body .container {
background-color: orange;
height: 50px;
width: 50%;
}
Not sure how hackish this sounds, but how about adding a transparent border?
I have a <div> element and I want to put a border on it. I know I can write style="border: 1px solid black", but this adds 2px to either side of the div, which is not what I want.
I would rather have this border be -1px from the edge of the div. The div itself is 100px x 100px, and if I add a border, then I have to do some mathematics to make the border appear.
Is there any way that I can make the border appear, and ensure the box will still be 100px (including the border)?
Set box-sizing property to border-box:
div {
box-sizing: border-box;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
width: 100px;
height: 100px;
border: 20px solid #f00;
background: #00f;
margin: 10px;
}
div + div {
border: 10px solid red;
}
<div>Hello!</div>
<div>Hello!</div>
It works on IE8 & above.
You can also use box-shadow like this:
div{
-webkit-box-shadow:inset 0px 0px 0px 10px #f00;
-moz-box-shadow:inset 0px 0px 0px 10px #f00;
box-shadow:inset 0px 0px 0px 10px #f00;
}
Example here: http://jsfiddle.net/nVyXS/ (hover to view border)
This works in modern browsers only. For example: No IE 8 support.
See caniuse.com (box-shadow feature) for more info.
Probably it is belated answer, but I want to share with my findings. I found 2 new approaches to this problem that I have not found here in the answers:
Inner border through box-shadow css property
Yes, box-shadow is used to add box-shadows to the elements. But you can specify inset shadow, that would look like a inner border rather like a shadow. You just need to set horizontal and vertical shadows to 0px, and the "spread" property of the box-shadow to the width of the border you want to have. So for the 'inner' border of 10px you would write the following:
div{
width:100px;
height:100px;
background-color:yellow;
box-shadow:0px 0px 0px 10px black inset;
margin-bottom:20px;
}
Here is jsFiddle example that illustrates the difference between box-shadow border and 'normal' border. This way your border and the box width are of total 100px including the border.
More about box-shadow:here
Border through outline css property
Here is another approach, but this way the border would be outside of the box. Here is an example.
As follows from the example, you can use css outline property, to set the border that does not affect the width and height of the element. This way, the border width is not added to the width of an element.
div{
width:100px;
height:100px;
background-color:yellow;
outline:10px solid black;
}
More about outline: here
Yahoo! This is really possible. I found it.
For Bottom Border:
div {box-shadow: 0px -3px 0px red inset; }
For Top Border:
div {box-shadow: 0px 3px 0px red inset; }
You can use the properties outline and outline-offset with a negative value instead of using a regular border, works for me:
div{
height: 100px;
width: 100px;
background-color: grey;
margin-bottom: 10px;
}
div#border{
border: 2px solid red;
}
div#outline{
outline: 2px solid red;
outline-offset: -2px;
}
Using a regular border.
<div id="border"></div>
Using outline and outline-offset.
<div id="outline"></div>
Although this question has already been adequately answered with solutions using the box-shadow and outline properties, I would like to slightly expand on this
for all those who have landed here (like myself) searching for a solution for an inner border with an offset
So let's say you have a black 100px x 100px div and you need to inset it with a white border - which has an inner offset of 5px (say) - this can still be done with the above properties.
box-shadow
The trick here is to know that multiple box-shadows are allowed, where the first shadow is on top and subsequent shadows have lower z-ordering.
With that knowledge, the box-shadow declaration will be:
box-shadow: inset 0 0 0 5px black, inset 0 0 0 10px white;
div {
width: 100px;
height: 100px;
background: black;
box-shadow: inset 0 0 0 5px black, inset 0 0 0 10px white;
}
<div></div>
Basically, what that declaration is saying is: render the last (10px white) shadow first, then render the previous 5px black shadow above it.
outline with outline-offset
For the same effect as above the outline declarations would be:
outline: 5px solid white;
outline-offset: -10px;
div {
width: 100px;
height: 100px;
background: black;
outline: 5px solid white;
outline-offset: -10px;
}
<div></div>
NB: outline-offset isn't supported by IE if that's important to you.
Codepen demo
Use pseudo element:
.button {
background: #333;
color: #fff;
float: left;
padding: 20px;
margin: 20px;
position: relative;
}
.button::after {
content: '';
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
border: 5px solid #f00;
}
<div class='button'>Hello</div>
Using ::after you are styling the virtual last child of the selected element. content property creates an anonymous replaced element.
We are containing the pseudo element using absolute position relative to the parent. Then you have freedom to have whatever custom background and/or border in the background of your main element.
This approach does not affect placement of the contents of the main element, which is different from using box-sizing: border-box;.
Consider this example:
.parent {
width: 200px;
}
.button {
background: #333;
color: #fff;
padding: 20px;
border: 5px solid #f00;
border-left-width: 20px;
box-sizing: border-box;
}
<div class='parent'>
<div class='button'>Hello</div>
</div>
Here .button width is constrained using the parent element. Setting the border-left-width adjusts the content-box size and thus the position of the text.
.parent {
width: 200px;
}
.button {
background: #333;
color: #fff;
padding: 20px;
position: relative;
}
.button::after {
content: '';
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
border: 5px solid #f00;
border-left-width: 20px;
}
<div class='parent'>
<div class='button'>Hello</div>
</div>
Using the pseudo-element approach does not affect the content-box size.
Depending on the application, approach using a pseudo-element might or might not be a desirable behaviour.
I know this is somewhat older, but since the keywords "border inside" landed me directly here, I would like to share some findings that may be worth mentioning here.
When I was adding a border on the hover state, i got the effects that OP is talking about. The border ads pixels to the dimension of the box which made it jumpy.
There is two more ways one can deal with this that also work for IE7.
1)
Have a border already attached to the element and simply change the color. This way the mathematics are already included.
div {
width:100px;
height:100px;
background-color: #aaa;
border: 2px solid #aaa; /* notice the solid */
}
div:hover {
border: 2px dashed #666;
}
2 )
Compensate your border with a negative margin. This will still add the extra pixels, but the positioning of the element will not be jumpy on
div {
width:100px;
height:100px;
background-color: #aaa;
}
div:hover {
margin: -2px;
border: 2px dashed #333;
}
11 Years Later but heres the answer:
Just use outline:
outline: 0.2vw solid red;
I hope i can help someone who sees this question also 11 Yeas Later.
for consistent rendering between new and older browsers, add a double container, the outer with the width, the inner with the border.
<div style="width:100px;">
<div style="border:2px solid #000;">
contents here
</div>
</div>
this is obviously only if your precise width is more important than having extra markup!
If you use box-sizing: border-box means not only border,
padding,margin, etc. All element will come inside of the parent
element.
div p {
box-sizing: border-box;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
width: 150px;
height:100%;
border: 20px solid #f00;
background-color: #00f;
color:#fff;
padding: 10px;
}
<div>
<p>It was popularised in the 1960s with the release of Letraset sheets</p>
</div>
Best cross browser solution (mostly for IE support) like #Steve said is to make a div 98px in width and height than add a border 1px around it, or you could make a background image for div 100x100 px and draw a border on it.
You can look at outline with offset but this needs some padding to exists on your div. Or you can absolutely position a border div inside, something like
<div id='parentDiv' style='position:relative'>
<div id='parentDivsContent'></div>
<div id='fakeBordersDiv'
style='position: absolute;width: 100%;
height: 100%;
z-index: 2;
border: 2px solid;
border-radius: 2px;'/>
</div>
You might need to fiddle with margins on the fake borders div to fit it as you like.
A more modern solution might be to use css variables and calc. calc is widely supported but variables is not yet in IE11 (polyfills available).
:root {
box-width: 100px;
border-width: 1px;
}
#box {
width: calc(var(--box-width) - var(--border-width));
}
Although this does use some calculations, which the original questions was looking to avoid. I think this is an ok time to use calculations as they are controlled by the css itself. It also has no need for additional markup or misappropriating other css properties that may be needed later on.
This solution is only really useful if a fixed height isn't needed.
One solution I didn't see mentioned above is the case where you have padding on your input, which I do 99% of the time. You can do something along the lines of...
input {
padding: 8px;
}
input.invalid {
border: 2px solid red;
padding: 6px; // 8px - border or "calc(8px - 2px)"
}
What I like about this is that I have the full menu of border + padding + transition properties for each side.
just wanted to know how i can change my navigation menu to have an indented effect. Like 1px of one light colour, and 1 px of darker colour.
Also does anybody know why i couldn't auto center the content in white, i tried margin:0 auto; but had to code in a weird workaround.

You could probably use border-style: inset; for the border effect you want, there's no need for nested block trickery or anything like that.
Your #infowrap element won't auto-center with a simple margin: 0 auto; because it is a block element and hence its default width is the width of its parent, this causes the auto left and right margins to come out as zero. The margin: 0 auto; will work if you wrap the insides in a block and give it an explicit width (for example: http://jsfiddle.net/ambiguous/aMemg/).
http://jsfiddle.net/jkmwy/
you can style the border left/right/top/bottom to create a bevel effect.
