This is the effect I'm trying to achieve:
This is a Facebook chat message, notice how the width of the element is strictly based around its textual contents.
If I change the text I write inside, the size of the <div> changes:
I'm trying to do the same thing with the following layout:
<div>Test message that goes ontothenextline</div>
And CSS:
div {
max-width: 190px;
// other arbitrary styles
}
But this is what I'm getting (as a basic example): https://jsfiddle.net/dr76t4t7/
How can I make the <div> better suit the contents of the text inside?
You are missing the display: inline-block and the padding.
.speech-bubble {
display: inline-block;
max-width: 190px;
background-color: #e1edff;
border: 1px solid #bdc7d6;
color: #4f5359;
text-shadow: 1px 1px 0 #fff;
padding: 8px 12px;
box-sizing: border-box;
border-radius: 15px 0 15px 15px;
}
https://jsfiddle.net/q35qmkgx/3/
Try this https://jsfiddle.net/q35qmkgx/7/
div {
background-color: blue;
color: white;
display:inline-block;
max-width:190px;
padding:5px;
word-break:break-all;
}
There is an odd problem here that I don't really understand.
I'm trying to just make the middle of the 3 vertical divs have another div inside it which has a black border and 10px of margin on all sides.
However, on the right side there is no visible margin, and on the bottom the div flows right out of the parent div and out of site into the footer.
What am I doing wrong? CSS for the middle div pair...
#mainContent {
height: 100%;
width: 100%;
}
#platter {
border: 1px solid black;
margin: 10px;
height: 100%;
width: 100%;
}
http://jsfiddle.net/Lf7wuty0/1/
Solution: http://jsfiddle.net/efordek0/1/
Borders are applied outside of the element, therefore if your element is width:100%; with a border: 1px solid black;, the border will fall outside of your desired constraint.
Instead of applying a margin to the inner-div #platter, apply a padding to the outer div #mainContent. This way the 100% values will still apply but be subtracted by the 10px padding of the #mainContent and your borders remain inside the desired area.
Here's the correct solution : http://jsfiddle.net/5L4tnwtg/
The changes:
Add:
*{
box-sizing:border-box;
-webkit-box-sizing:border-box;
-moz-box-sizing:border-box;
}
Modify:
#mainContent {
height: 100%;
width:100%;
padding: 10px;
}
#platter {
border: 1px solid black;
height: 100%;
width: 100%;
}
I have some divs and and input box. When I resize the window, the divs adapt appropriately, but the input gets clipped. How do I make the input resize to the screen size while having a max width of 400px? Here are screenshots of the two states: Looks good. But when the page is narrowed the divs respond but the input gets cut but the divs are good.
Here is how I styled my input
.text-input {
display: block;
width: 100%;
font-family: sans-serif;
font-size: 1em;
appearance: none;
border-radius: none;
padding: 0.5em;
border: solid 1px #fff;
box-shadow: inset 1px 1px 2px 1px #707070;
transition: box-shadow 0.3s;
max-width: 400px;
display: inline-block;
}
.text-input:focus,
.text-input.focus {
outline: none;
box-shadow: inset 1px 1px 2px 1px #c9c9c9;
}
My question is, how should I style the input to make it behave the same as the divs? Please also what is the intuition behind the solution?
You can put the input inside a div, give the input a width:100%;.
HTML
<div>
<input type="text" />
</div>
CSS
input[type=text] {
width: 100%;
max-width: 400px;
box-sizing: border-box;
}
div {
border: solid 1px red
}
DEMO
here is the fiddle
the problem was width was 100% and padding was xx px so it comes to 100% + xxpx thats the reason it was exceeding 100%
Js Fiddle
box-sizing:border-box;
this property gives padding, border from inside which doesn't allow the width to exceed from 100%
Simply remove max-width from your code. Replace it with 100%.
If you want to be more web-responsive, you can define more deffinitions, each for different window size, like so:
#media screen and (max-width:720px) { width: 90%; }
#media screen and (min-width:720px) { width: 100%; }
Google responsive web design and screen width examples:)
I have the following CSS:
#imageContainer {
width: 100%;
margin: 0px;
margin-bottom: 10px;
}
.divSelectImage {
border: 2px solid red;
width: 25%;
margin: 0px;
margin-bottom: 10px;
float: left;
}
I have four instances of .divSelectImage which is why the width is 25%. I expect to see all four images side by side inside #imageContainer. So essentially, the four images should take up 100% of the #imageContainer which in turn takes up 100% of the screen.
But I don't. Despite checking firebug, at 25% each, the last image goes to the next line. I have to make them to about 24.5% for them to fit, but I don't want the white space at the end.
This occurs in both Firefox and Google Chrome.
Is there some kind of CSS wizardry that I am missing? How can I accomplish this?
I have set up the scenario on JSFiddle: http://jsfiddle.net/J3KXE/
Its because you haven't accounted for the 2px of border on each image, adding 12px in addition to the 100% width of its containing block. You can use the box-sizing property thats new to CSS to constrain the border and padding areas to the elements' content width:
#imageContainer {
width: 100%;
margin: 0px;
margin-bottom: 10px;
}
.divSelectImage {
border: 2px solid red;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;
width: 25%;
margin: 0px;
margin-bottom: 10px;
float: left;
}
http://jsfiddle.net/J3KXE/1/
2 solutions :
box-sizing: border-box;
or
flexbox and all this shit (see http://coding.smashingmagazine.com/2013/05/22/centering-elements-with-flexbox/)
You have a border of 2px which increases the size of the boxes to 25% plus these 2px on each side. If you don't have to support IE7- you can simply use box-sizing: border-box. If you have to take older browser into account you'd have to declare a wrapper div width 25% without any border/margin/padding and add those styles to the child element.
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.
