Nested divs Background-color - css

I am trying to change background-color of the parent div behind the children ones. Kind of like how the how the background in this image is darker than the other divs.
here is my HTML:
<div class="main">
<div class="sub">
</div>
</div>
CSS:
div.main {
background-color:#AAAAAA;
}
div.sub {
border-style:solid;
border-width:1px;
border-color:#AAAAAA;
border-radius:2px;
margin:10px;
box-shadow: 0px 0px 5px #AAAAAA;
}
The main div is not the color #AAAAAA
Thanks, Ben

You forgot to add background-color in sub class and also add padding for the clear view.
div.main {
background-color:#AAAAAA;
padding:20px;
}
div.sub {
border-style:solid;
border-width:1px;
border-color:#AAAAAA;
border-radius:2px;
margin:10px;
box-shadow: 0px 0px 5px #AAAAAA;
padding:10px;
background-color:#fff;
}
I tried doing the same thing, it may help: JSFiddle

just assign a different background color to your different divs, maybe add some padding to make it show?
div.main {
background-color:#888888; //<---------- darker
padding: 10px; //<-------- padding
}
div.sub {
border-style:solid;
background-color:#AAAAAA; //<---------- lighter
border-width:1px;
border-color:#AAAAAA;
border-radius:2px;
margin:10px;
box-shadow: 0px 0px 5px #AAAAAA;
}

Changing stacking order for CSS pseudo element

I am in the process of designing a 3 stage progress bar in pure CSS. My current effort is shown below.
#progBar
{
background-color:#bdbdbd;
padding:1.5vw;
position:relative;
height:9vw;
}
.progcapt
{
background-color: #526cfd;
color: transparent;
text-shadow: 0px 2px 3px #526cfd;
-webkit-background-clip:text;
font-family:'arial black';
font-size:3vw
}
#cOne
{
position:absolute;
left:calc(50% - 2.5vw);
top:calc(50% - 2.5vw);
border-radius:5vw;
height:5vw;
width:5vw;
border:1px solid #526cfd;
text-align:center;
display:flex;
align-items:center;
justify-content:center;
box-shadow:0px 0px 3vw #526cfd;
background-color:white;
}
#cOne::before
{
position:absolute;
width:50vw;
height:1vw;
background-color:rgba(82,108,253,0.5);
content:'';
/*z-index:-1; does not give the expected result*/
}
#cOneRing
{
position:absolute;
top:-calc(0.5vw + 1px);
left:-calc(0.5vw + 1px);
width:6vw;
height:6vw;
border:1px solid #526cfd;
border-radius:6vw;
}
<div id='progBar'>
<div id='cOne'>
<span class='progcapt'>1</span>
<div id='cOneRing'> </div>
</div>
</div>
The intent here is this
There will be three disc, one for each step
I am using the central disc as my "anchor"
Each disc is shown with an annular border which I create by absolutely positioning the disc and making the annulus its child.
The ::before pseudo-element for this anchor is used to create the track for the progress bar
The ensemble - the three circles and the track - are placed in an relatively positioned rectangular bar which acts as the background
The issue I have run into - I thought I would be able to send the track bar behind its parent disc element by setting its z-index attribute to -1. However, that simply causes it to disappear altogether. Clearly, I am doing something wrong here but I am unable to spot what that might be. Hopefully, someone here will be able to spot the error.
As far as I understood you need this
#progBar {z-index: -2;}
#cOne::after { z-index: -1;}
#progBar
{
z-index: -2;
background-color:#bdbdbd;
padding:1.5vw;
position:relative;
height:9vw;
}
.progcapt
{
background-color: #526cfd;
color: transparent;
text-shadow: 0px 2px 3px #526cfd;
-webkit-background-clip:text;
font-family:'arial black';
font-size:3vw
}
#cOne
{
position:absolute;
left:calc(50% - 2.5vw);
top:calc(50% - 2.5vw);
border-radius:5vw;
height:5vw;
width:5vw;
border:1px solid #526cfd;
text-align:center;
display:flex;
align-items:center;
justify-content:center;
box-shadow:0px 0px 3vw #526cfd;
background-color:white;
}
#cOne::before
{
position:absolute;
width:50vw;
height:1vw;
background-color:rgba(82,108,253,0.5);
content:'';
z-index:-1;
}
#cOneRing
{
position:absolute;
top:-calc(0.5vw + 1px);
left:-calc(0.5vw + 1px);
width:6vw;
height:6vw;
border:1px solid #526cfd;
border-radius:6vw;
}
<div id='progBar'>
<div id='cOne'>
<span class='progcapt'>1</span>
<div id='cOneRing'> </div>
</div>

box shadow in css

How can i get these spaces covered with this box shadow?
CSS-
.button
{
height:24px;
width:120px;
background:black;
position:absolute;
border-radius:2px;
padding:3px;
box-shadow:4px 4px 0px 0px #444;
}
Just a fiddle
Changing the h-shadow and v-shadow will position the shadow on the box.
If you want the shadow to be closer, change the distance of the shadow.
Test it here
Using close shadows might not get you that much effect. Instead you can use background properties and positions... Here is a good example.
Try this:-
.button
{
height:24px;
width:120px;
background:black;
position:absolute;
border-radius:2px;
padding:3px;
box-shadow:2px 2px 0px 2px #444; // changed
}

how to force a div to expand to its content?

although my questions has been answered lots of times before, but all the proposed solution I have tried and nothing seems to work.
what am trying to do is a big div that contains li tags; the li tags will also contain anchor tag, 2 divs and p tag.
to understand the big picture.. am trying to make a posting wall (activity-board), the wall will have posts looks like a bubble (div post) and the bubble will point (post-arrow) to a thumbnail image (a thumb3), to make the bubble style I made the post div absolute positioned with z-index less than the arrow-post.
and here is my css:
.activity-board {
background:#fff;
width:600px;
min-height:652px;
height:auto;
border:solid 2px #e7d28d;
border-radius: 6px;
-moz-border-radius: 6px;
-webkit-border-radius: 6px;
-webkit-box-shadow: inset 0px 0px 0px 3px rgba(255, 255, 255, 1);
box-shadow: inset 0px 0px 0px 3px rgba(255, 255, 255, 1);
float:left;
margin-left:20px;
}
.post-body{
position:relative;
display:block;
list-style-type:none;
width:600px;
height:auto;
background:#f9f9f9;
border-bottom:1px solid #CBCBCB;
border-radius:4px 4px 0 0;
-moz-border-radius:4px 4px 0 0;
-webkit-border-radius:4px 4px 0 0;
background: #fff;
float:left;
overflow:visible;
clear:both;
z-index:9;
}
.post{
position:absolute;
width:500px;
line-height:20px;
height:auto;
background:#FFF;
display:block;
margin-top:22.5px;
margin-left:77px;
text-align:left;
float:left;
z-index:1;
}
.post-arrow{
position:relative;
margin-top:32px;
margin-left:6px;
width:12px;
height:18px;
background:url(images/post-arrow.png);
float:left;
z-index:5;
}
.post p{ color:#025373; padding:8px; word-wrap:break-word; }
a.thumb-3 {
margin-top:18px;
display:block;
margin-left:18px;
width:46px;
height:46px;
border-radius: 5px;
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
z-index:10;
float:left;
}
a.thumb-3 img{
padding:0;
margin:0 auto;
width:46px;
height:46px;
float:left;
border-radius:3px;
-moz-border-radius:3px;
-webkit-border-radius:3px;
}
here is my html:
<ul>
<li class="post-body">
<a class="thumb-3"><img src="images/Alsheikh Center (177).jpg" /></a>
<div class="post-arrow"></div>
<div class="post">
<p>
Hi there!
</p>
</div>
</li>
</ul>
http://jsfiddle.net/r9YpX/
Everything worked fine but the li tag does not expand to the content.. it only expands if I change the position of the post div to relative not absolute, which I cant change because it must be absolutely positioned under the arrow image to give it the bubble look.
any help would be appreciated.
Thanks.
ok Thanks guys i figuered it out.. I made position:relative and changed margin for post div and it worked! I thought I did this but perhaps I did something wrong that make it not work

Why doesn't the title tooltip work for floated elements?

I have a floated element, the whole purpose of which is to display an 'x' signifying that you can remove something:
.remove_button{
background-color:#ff3300;
color:#ffffff;
font-family:Courier New,sans-serif;
font-weight:900;
font-size:20px;
float:right;
border-radius:5px;
padding:0px 6px 0px 6px;
margin-right:15px;
}
<div class="remove_button" title="Remove">x</div>
It does display a neat little 'x' over a red background (no need to make a picture, I'm bad at that), but the problem is that when the mouse hovers over the button the title attribute shows up inside the button, and as a tooltip too:
------xRemove------ one '-' is one pixel of padding
try this,
.remove_button{
background-color:#ff3300;
color:#ffffff;
font-family:Courier New,sans-serif;
font-weight:900;
font-size:20px;
float:right;
border-radius:5px;
padding:0px 6px 0px 6px;
margin-right:15px;
position:relative;
}
​ .tip{
position:absolute;
display:none;
border:1px solid #aab;
background:#eef;
padding:0 3px;
left:15px;
top:25px;
}
.remove_button:hover .tip{
display:block;
}

CSS hover border makes elements adjust slightly

I have an unordered list full or anchors. I have a CSS :Hover event that adds borders to it but all the anchors to the left slightly adjust when i hover because it is adding 1px to the width and auto adjusting. how do i make sure the positioning is absolute?
div a:visited, #homeheader a{
text-decoration:none;
color:black;
margin-right:5px;
}
div a:hover{
background-color:#D0DDF2;
border-radius:5px;
border:1px solid #102447;
}
div li{
padding:0;
margin:0px 10px;
display:inline;
font-size:1em;
}
<div>
<ul>
<li>this</li>
<li>that</li>
<li>this again</li>
<li>that again</li>
</ul>
</div>
I made a JS Fiddle demo here.
You can add a transparent border to the non-hover state to avoid the "jumpiness" when the border appears:
http://jsfiddle.net/TEUhM/3/
#homeheader a:visited, #homeheader a{
border:1px solid transparent;
}
You can also use outline, which won't affect the width i.e. so no "jump" effect. However,support for a rounded outline may be limited.
You could use a box shadow, rather than a border for this sort of functionality.
This works because your shadow doesn't 'take size in the DOM', and so won't affect the positioning, unlike that of a border.
Try using a declaration like
box-shadow:0 0 1px 1px #102447;
instead of your
border:1px solid #102447;
on your hover state.
Below is a quick demo of this in action:
DEMO
#homeheader a:visited,
#homeheader a {
text-decoration: none;
color: black;
margin-right: 5px;
}
#homeheader a:hover {
background-color: #D0DDF2;
border-radius: 5px;
box-shadow: 0 0 1px #102447;
}
#homeheader li {
padding: 0;
margin: 0px 10px;
display: inline;
font-size: 1em;
}
<div id="homecontainer">
<div id="homeheader">
<ul>
<li>this
</li>
<li>that
</li>
<li>this again
</li>
<li>that again
</li>
</ul>
</div>
</div>
Add a margin of 1px and remove that margin on hover, so it is replaced by the border.

After taking a long time pressure i found a cool solution.
Hope that it will help others.
on the add the folloing code :
HTML
<div class="border-test">
<h2> title </h2>
<p> Technology founders churn rate niche market </p>
</div>
CSS
.border-test {
outline: 1px solid red;
border: 5px solid transparent;
}
.border-test:hover {
outline: 0px solid transparent;
border: 5px solid red;
}

Hope it will help.
No one has mentioned it here, but the best and simplest solution to this in my opinion is to use "box shadow" instead of borders. The magic is on the "inset" value which allows it be like a boarder.
box-shadow: inset 0 -3px 0 0 red;
You can offset the X or Y to change top/bottom and use -negative value for opposite sides.
.button {
width: 200px;
height: 50px;
padding: auto;
background-color: grey;
text-align: center;
}
.button:hover {
box-shadow: inset 0 -3px 0 0 red;
background-color: lightgrey;
}
<div class="button"> Button </div>
You can use box-shadow which does not change your box-size, unlike border.
Here is a little tutorial.
Just add the following code into your css file
#homeheader a {
border:1px solid transparent;
}
The CSS "box-sizing" attribute fixed this problem for me. If you give your element
.class-name {
box-sizing: border-box;
}
Then the width of the border is added to the inside of the box when the browser calculates its width. This way when you turn the border style on and off, the size of the element doesn't change (which is what causes the jittering you observed).
This is a new technology, but the support for border-box is pretty consistent. Here is a demo!
The easiest method I found was using 'outline' instead of 'border'.
#home:hover{
outline:1px solid white;
}
instead of
#home:hover{
border:1px solid white;
}
Works the best!
https://www.kirupa.com/html5/display_an_outline_instead_of_a_border_hover.htm
Add a negative margin on hover to compensate:
#homeheader a:hover{
border: 1px solid #102447;
margin: -1px;
}
updated fiddle
In the fiddle the margin: -1px; is a little more complex because there was a margin-right getting overridden, but it's still just a matter of subtracting the newly-occupied space.
I too was facing the same problem. The fix mentioned by Wesley Murch works! i.e. adding a transparent border around the element to be hovered.
I had a ul on which :hover was added to every li. Every time, I hovered on each list item, the elements contained inside li too moved.
Here is the relevant code:
html
<ul>
<li class="connectionsListItem" id="connectionsListItem-0">
<div class="listItemContentDiv" id="listItemContentDiv-0">
<span class="connectionIconSpan"></span>
<div class="connectListAnchorDiv">
Test1
</div>
</div>
</li>
</ul>
css
.listItemContentDiv
{
display: inline-block;
padding: 8px;
right: 0;
text-align: left;
text-decoration: none;
text-indent: 0;
}
.connectionIconSpan
{
background-image: url("../images/connection4.png");
background-position: 100% 50%;
background-repeat: no-repeat;
cursor: pointer;
padding-right: 0;
background-color: transparent;
border: medium none;
clear: both;
float: left;
height: 32px;
width: 32px;
}
.connectListAnchorDiv
{
float: right;
margin-top: 4px;
}
The hover defn on each list item:
.connectionsListItem:hover
{
background-color: #F0F0F0;
background-image: linear-gradient(#E7E7E7, #E7E7E7 38%, #D7D7D7);
box-shadow: none;
text-shadow: none;
border-radius: 10px 10px 10px 10px;
border-color: #AAAAAA;
border-style: solid;
}
The above code used to make the containing elements shift, whenever I hovered over connectionsListItem. The fix was this added to the css as:
.connectionsListItem
{
border:1px solid transparent;
}
Use :before to create the border, that way it won't modify the actual content and gives you more freedom. Check it out here:
http://codepen.io/jorgenrique/pen/JGqOMb
<div class='border'>Border</div>
<div class='before'>Before</div>
div{
width:300px;
height:100px;
text-align:center;
margin:1rem;
position:relative;
display:flex;
justify-content:center;
align-items: center;
background-color:#eee;
}
.border{
border-left:10px solid deepPink;
}
.before{
&:before{
content:"";
position:absolute;
background-color:deepPink;
width:10px;
height:100%;
left:0;
top:0;
}
&:hover{
background-color:#ccc;
&:before{
width:0px;
transition:0.2s;
}
}
}
Be careful if you also use padding.
In my case, I had a 5px padding inside the hover defn. It should be moved inside the actual class of the element you want to hover over.
