How to get box-shadow over another box - html

I am trying to create a box shadow but as soon as another box hits it the box shadow is invisible. I'd like to have the box-shadow go over the other box.
Here an example of what is going wrong. As you can see there is a shadow where there is not box.
Fiddle
HTML
<header>
</header>
<div id="content">
</div>
CSS
header {
height: 100px;
background: black;
box-shadow: 1px 1px 5px rgba(0,0,0, 0.7);
}
#content {
width: 350px;
height: 300px;
margin: 0 auto;
background: #CCCCCC;
}

HTML elements are positioned statically by default in document normal flow.
You have to position the header as relative and add a higher z-index (if needed) to bring that element at the top of the others without changing layout, as follows:
header {
height: 100px;
background: black;
box-shadow: 1px 1px 5px rgba(0,0,0, 0.7);
position: relative;
z-index: 10; /* optional */
}
WORKING DEMO.

try position:absolute or relative for the header
header {
height: 100px;
background: black;
box-shadow: 1px 1px 5px rgba(0,0,0, 0.7);
position:absolute;
width:100%;
}
#content {
width: 350px;
height: 300px;
margin: 0 auto;
background: #CCCCCC;
}

Create inset window boxshadow border with space between actual window and border

I want to create the white border seen in the image below with CSS. White border that is set 25px inside the window. Iv'e tried to use box-shadow inset however was not able to create the space between the edge of the window.
I used this css:
border: 3px solid white; //took this out but still no luck
box-shadow: inset 0 0 0 5px #FFFFFF;
I also tried without the normal border as well.
I think I can create an overlay div that has a padding or margin and give it a border, but the problem is the content needs to be scrollable and clickable below it.
The goal:
The white box just above the icons.
Use a pseudo element
.parent {
position: relative;
height: 200px;
}
.wrapper {
height: 100%;
overflow-y: auto;
}
.content {
height: 600px;
background: url(http://lorempixel.com/600/600/abstract/1) no-repeat center center / cover;
}
.parent:after {
content: '';
position: absolute;
left: 25px;
top: 25px;
right: 40px;
bottom: 25px;
border: 2px solid white;
}
<div class="parent">
<div class="wrapper">
<div class="content">
</div>
</div>
</div>
Use a transparent border to set the shadow where you want it.
The remaining problem is to extend the image to the borders. Use background-origin for this.
.test {
height: 250px;
width: 400px;
background-image: url(http://lorempixel.com/600/400);
background-origin: border-box;
background-size: cover;
border: 50px transparent solid;
box-shadow: inset 0px 0px 5px 5px cyan;
}
<div class="test">
</div>
hope this help.
body{
background: #000;
}

How to create a border gap illusion

This is the illusion that I am attempting to create:
Notice that my designer wants the border cut off in the middle of the div, this is what I need to know how to do. I don't think overlapping with a z-index will work because of how the HTML is laid out.
This is the HTML code of which the structure may not be changed for maximum device compatibility, however, if adding an element is the solution, I believe that may be done:
<div id="nav_icons_con" class="mopn">
<div id="inner_nav_container" class="show_inner_nav">
<div class="nav_link_container">Home</div>
</div>
</div>
Here is the basic current CSS code:
#nav_icons_con {
z-index: 1;
cursor:pointer;
height: 5.005em;
width: 5.005em;background-image:url(background.png);
background-size:70%;
background-repeat:no-repeat;
background-position:center;
margin:.385em .385em 0 0;
}
#nav_icons_con.mopn{
background-color:#FFF;
border:2px solid #83C5E6;
border-bottom:none;
box-shadow:5px 5px 10px #666;
}
#inner_nav_container, .inner_nav_container{
cursor:pointer;
display:none;
position:absolute;
top:5.39em;
right:.385em;
width:12.5em;
white-space:normal;
background-color:#FFF;
border:2px solid #83C5E6;
border-top:none;
box-shadow:5px 5px 10px #666;
}
#inner_nav_container.show_inner_nav, .inner_nav_container.show_inner_nav{display:block;}
The typical way to do this is to position the tab element over the sub element, so as to cover up that section of the border. However, the use of box-shadow complicates this.
One way is to add another element inside the root element, so that the root element can still cast the shadow, but the element inside is positioned above. See my code below, for a basic example.
Working Example:
.icon {
width: 50px;
height: 50px;
position: relative;
/*Create the shape for the shadow.*/
border: 5px solid #83C5E6;
box-shadow: 5px 5px 10px #666;
}
.icon-content {
background: #fff;
position: relative;
/*Move back over the border.*/
top: -5px;
left: -5px;
/*Make tall enough to cover the top border.*/
width: 50px;
height: 55px;
/*Add border, except on the bottom.*/
border: 5px solid #83C5E6;
border-bottom: 0;
/*Position up a layer.*/
z-index: 1;
}
.nav {
position: absolute;
left: -5px;
top: 100%;
width: 400px;
padding: 1em;
background: #fff;
border: 5px solid #83C5E6;
box-shadow: 5px 5px 10px #666;
}
<div class="icon">
<div class="icon-content">
</div>
<div class="nav">
<div class="item">Home</div>
</div>
</div>

why wont my containers extend to encompass my content?

I'm having issues getting my content box to extend to encompass everything within it. shouldnt max-height:100% do this?
http://codepen.io/anon/pen/xujAC
There's the codepen of my code. The red and blue background are for visual reference only.
Shouldnt the blue background (.container) only extend 20px below the blocks?
Pretty new at this and learning as I go. I'm probably missing something easy.
Thanks a lot.
You have the height of your .container set to 100%. In this sample, it will be as tall as its containing element. Because its top is set to 80px and its height is that of its parent, it will extend below the bottom by ~ 80px.
Other things that throw this off are:
floated elements are outside the regular flow which means the containing element can't calculate the height of its children. In this case, I think the simplest fix would be to use position: inline-block; for the children.
The child elements banner and container are absolutely positioned. This also take them outside the flow of the document. In this example, I believe you can get the results you are looking for using relative positioning.
Margins are also throwing off the layout. Here you can using padding in #content to achieve better results.

CSS transparency issues in nested elements

hey there i wonder if any of you have come across a similar issue? i am working on an ad section of the webpage and its got a really cool background that i would like to carry on into sections of the elements so i have a box that hold a box for a rss feed into updates made on the website and then i have a box for adverts. here is my html:
<div class="side">
<div id="ad">
bla
</div>
<div id="rss_news">
double bla
</div>
</div>
and the css:
.side {
float: left;
background-color: black;
width: 300px;
min-height: 710px;
padding: 0 0 0 0px;
margin-top: 25px;
border: 1px solid white;
border-radius: 8px 8px 8px 8px;
opacity: 0.3;
}
#ad {
border: 1px solid blue;
height: 320px;
max-height: 350px;
margin: 15px;
opacity: 1;
}
#rss_news {
border: 1px solid yellow;
height: 320px;
max-height: 350px;
margin: 15px;
opacity: 1;
}
as you can see and as i was anticipating the side class immits his attributes on the ones nested within him. is there a way that i could somehow tell the other id tags to ignore that opacity?
thanks in advance :D
There is no way to make descendants ignore the parent's opacity.
You can use rgba/hsla colors to get a partially transparent background, without affecting the children's visibility. Example:
.side {
background-color: rgba(0,0,0, 0.3);
}
Demo: http://jsfiddle.net/ywQy5/
See also:
MDN: hsla colors
MDN: rgba colors
You can use css3 rgba property for this & for IE you can use IE filter.Write like this:
.side{
background-color: rgba(0,0,0, 0.5);
background: transparent;
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#7F000000,endColorstr=#7F000000); /* IE*/
zoom: 1;
}

CSS Inset Borders

I need to create a solid color inset border. This is the bit of CSS I'm using:
border: 10px inset rgba(51,153,0,0.65);
Unfortunately that creates a 3D ridged border (ignore the squares and dark description box)
You could use box-shadow, possibly:
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 10px #0f0;
}
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 10px #0f0;
}
<div id="something"></div>
This has the advantage that it will overlay the background-image of the div, but it is, of course, blurred (as you'd expect from the box-shadow property). To build up the density of the shadow you can add additional shadows of course:
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 20px #0f0, inset 0 0 20px #0f0, inset 0 0 20px #0f0;
}
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 20px #0f0, inset 0 0 20px #0f0, inset 0 0 20px #0f0;
}
<div id="something"></div>
Edited because I realised that I'm an idiot, and forgot to offer the simplest solution first, which is using an otherwise-empty child element to apply the borders over the background:
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
padding: 0;
position: relative;
}
#something div {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
border: 10px solid rgba(0, 255, 0, 0.6);
}
<div id="something">
<div></div>
</div>
Edited after #CoryDanielson's comment, below:
jsfiddle.net/dPcDu/2 you can add a 4th px parameter for the box-shadow that does the spread and will more easily reflect his images.
#something {
background: transparent url(https://i.stack.imgur.com/RL5UH.png) 50% 50% no-repeat;
min-width: 300px;
min-height: 300px;
box-shadow: inset 0 0 0 10px rgba(0, 255, 0, 0.5);
}
<div id="something"></div>
I would recomnend using box-sizing.
*{
-webkit-box-sizing:border-box;
-moz-box-sizing:border-box;
-ms-box-sizing:border-box;
box-sizing:border-box;
}
#bar{
border: 10px solid green;
}
To produce a border inset within an element the only solution I've found (and I've tried all the suggestions in this thread to no avail) is to use a pseudo-element such as :before
E.g.
.has-inset-border:before {
content: " "; /* to ensure it displays */
position: absolute;
left: 10px;
right: 10px;
top: 10px;
bottom: 10px;
border: 4px dashed red;
pointer-events: none; /* user can't click on it */
}
The box-sizing property won't work, as the border always ends up outside everything.
The box-shadow options has the dual disadvantages of not really working and not being supported as widely (and costing more CPU cycles to render, if you care).
It's an old trick, but I still find the easiest way to do this is to use outline-offset with a negative value (example below uses -6px). Here's a fiddle of it—I've made the outer border red and the outline white to differentiate the two:
.outline-offset {
width:300px;
height:200px;
background:#333c4b;
border:2px solid red;
outline:2px #fff solid;
outline-offset:-6px;
}
<div class="outline-offset"></div>
If you want to make sure the border is on the inside of your element, you can use
box-sizing:border-box;
this will place the following border on the inside of the element:
border: 10px solid black;
(similar result you'd get using the additonal parameter inset on box-shadow, but instead this one is for the real border and you can still use your shadow for something else.)
Note to another answer above: as soon as you use any inset on box-shadow of a certain element, you are limited to a maximum of 2 box-shadows on that element and would require a wrapper div for further shadowing.
Both solutions should as well get you rid of the undesired 3D effects.
Also note both solutions are stackable (see the example I've added in 2018)
.example-border {
width:100px;
height:100px;
border:40px solid blue;
box-sizing:border-box;
float:left;
}
.example-shadow {
width:100px;
height:100px;
float:left;
margin-left:20px;
box-shadow:0 0 0 40px green inset;
}
.example-combined {
width:100px;
height:100px;
float:left;
margin-left:20px;
border:20px solid orange;
box-sizing:border-box;
box-shadow:0 0 0 20px red inset;
}
<div class="example-border"></div>
<div class="example-shadow"></div>
<div class="example-combined"></div>
I don't know what you are comparing to.
But a super simple way to have a border look inset when compared to other non-bordered items is to add a border: ?px solid transparent; to whatever items do not have a border.
It will make the bordered item look inset.

Simple SCSS solution with pseudo-elements
Live demo: https://codepen.io/vlasterx/pen/xaMgag
// Change border size here
$border-width: 5px;
.element-with-border {
display: flex;
height: 100px;
width: 100%;
position: relative;
background-color: #f2f2f2;
box-sizing: border-box;
// Use pseudo-element to create inset border
&:before {
position: absolute;
content: ' ';
display: flex;
border: $border-width solid black;
left: 0;
right: 0;
top: 0;
bottom: 0;
border: $border-width solid black;
// Important: We must deduct border size from width and height
width: calc(100% - $border-width);
height: calc(100% - $border-width);
}
}
<div class="element-with-border">
Lorem ipsum dolor sit amet
</div>
You can do this:
.thing {
border: 2px solid transparent;
}
.thing:hover {
border: 2px solid green;
}
If box-sizing is not an option, another way to do this is just to make it a child of the sized element.
Demo
CSS
.box {
width: 100px;
height: 100px;
display: inline-block;
margin-right: 5px;
}
.border {
border: 1px solid;
display: block;
}
.medium { border-width: 10px; }
.large { border-width: 25px; }
HTML
<div class="box">
<div class="border small">A</div>
</div>
<div class="box">
<div class="border medium">B</div>
</div>
<div class="box">
<div class="border large">C</div>
</div>
I know this is three years old, but thought it might be helpful to someone.
The concept is to use the :after (or :before) selector to position a border within the parent element.
.container{
position:relative; /*Position must be set to something*/
}
.container:after{
position:relative;
top: 0;
content:"";
left:0;
height: 100%; /*Set pixel height and width if not defined in parent element*/
width: 100%;
-webkit-box-sizing:border-box;
-moz-box-sizing:border-box;
-ms-box-sizing:border-box;
box-sizing:border-box;
border:1px solid #000; /*set your border style*/
}
You may use background-clip: border-box;
Example:
.example {
padding: 2em;
border: 10px solid rgba(51,153,0,0.65);
background-clip: border-box;
background-color: yellow;
}
<div class="example">Example with background-clip: border-box;</div>
So I was trying to have a border appear on hover but it moved the entire bottom bar of the main menu which didn't look all that good I fixed it with the following:
#top-menu .menu-item a:hover {
border-bottom:4px solid #ec1c24;
padding-bottom:14px !important;
}
#top-menu .menu-item a {
padding-bottom:18px !important;
}
I hope this will help someone out there.
Simpler + better | img tag | z-index | link image | "alt" attribute
I figured out a method where you do not need to use the image as a background image but use the img HTML tag inside the div, and using z-index of the div as a negative value.
Advantages:
The image can now become a link to a lightbox or to another page
The img:hover style can now change image itself, for example:
black/white to color, low to high opacity, and much more.
Animations of image are possible The image is more accessible because
of the alt tag you can use.
For SEO the alt tag is important for keywords
#borders {
margin: 10px auto;
width: 300px;
height: 300px;
position:relative;
box-shadow: inset 0 0 0 10px rgba(0, 255, 0, 0.5);
}
img {
position:absolute;
top:0;
bottom:0;
left:0;
right: 0;
z-index: -1;
}
<div id="borders">
