Trying to solve a recent question, I found out what looks like a Chrome and IE bug.
When I set 2 divs, and the containing div has border-radius and overflow: hidden, the inner div is responding to hover on the area that shouldn't be
In this snippet, hover the grey area. The inner div will change color. This happens in IE and Chrome, but not in FF
.innerw, .innerw2 {
width: 240px;
height: 240px;
position: relative;
border-radius: 50%;
}
.innerw {
left: 0px;
top: 0px;
overflow: hidden;
}
.innerw2 {
left: 80px;
top: 0px;
background-color: palegreen;
}
.innerw2:hover {
background-color: green;
}
.inner2 {
left: 168px;
top: 13px;
width: 79px;
height: 229px;
background-color: grey;
z-index: -1;
position: absolute;
}
<div class="innerw">
<div class="innerw2">
</div>
</div>
<div class="inner2"></div>
I would like to know a way to avoid this bug.
I think this has to do with the relative positioning. If you drop the relative positioning on .innerw2, and use margin-left instead, this no longer occurs.

I have made a footer in Photoshop looking like this:
As you can see, the footer here is slightly arced all the way across. I have tried doing something with border-radius, but that almost only targets the edge, which makes the arc more curved in the edges, and not even receiving the effect of a subtle arced footer as seen in the image.
Is there an easy CSS way to do this, or do I need some JavaScript or something to achieve this?
Use a pseudo element of the footer with border-radius to make the arch.
I made them different colors here so you can see which element is which.
body {
margin: 0;
max-height: 100vh;
overflow: hidden;
}
footer {
bottom: 0; left: 0; right: 0;
position: absolute;
background: brown;
height: 10vh;
}
footer::before {
content: '';
background: red;
width: 200%;
position: absolute;
left: 50%;
top: -100%;
transform: translateX(-50%);
height: 1000%;
border-radius: 50%;
z-index: -1;
}
<footer></footer>
This solution uses a large width to get a more pleasant curve, but without the pseudo-element:
footer {
background-color: red;
width: 200%;
transform: translateX(-25%);
height: 200px;
border-radius: 50% 50% 0 0;
}
<div>
<footer></footer>
</div>
Its not perfect, but here i've got a really really big circle that's absolutely positioned with the overflow hidden so that you only see the top part of the arc.
#container{
background: grey;
height:300px;
width:500px;
position:relative;
overflow:hidden;
}
#arc{
position: absolute;
top:200px;
left:-800px;
width:2000px;
height:2000px;
border-radius:2000px;
background:brown;
}
<div id="container">
<div id="arc">
</div>
</div>

You can actually use border-radius to do this without a pseudo element.
.arc {
width: 100%;
height:500px;
background: #000000;
border-radius: 50% / 30px;
border-bottom-right-radius: 0;
border-bottom-left-radius: 0;
}
<div class="arc"></div>
will work just fine. Make sure that when you use:
border-radius: 50% / 30px;
the first property is always "50%" as this will ensure the arc meets in the middle. The second property (after the "/") is the height of the arc measured from the middle to the edges
The circle solution, but it's responsive!
footer {
background: #ececec;
height: 200px;
width: 100%;
position: relative;
overflow: hidden;
}
.arc {
position: absolute;
top: 0px;
right: calc(-80%);
width: 300%;
padding-top: 100%;
border-radius: 100%;
background: black;
}
<footer>
<div class="arc">
</div>
</footer>
I have been battling this problem for a good 6 hours now on IE. There seems to be extra padding when we use the before tag with position to be absolute.
CSS
.rteEditable{
background-color:green;
position: relative;
width: 200px;
height: 400px;
min-height: 400px;
}
.rteEditable p{
padding-left: 46px;
}
.rteEditable:before{
position: absolute;
height: 100%;
width: 40px;
content:'';
background-color:red;
}
HTML
<div class="rteEditable" contenteditable="true">

Let me share an example for better illustrating:
jsFiddle: http://jsfiddle.net/yhurak3e/
Or you can read it here:
HTML:
<div id="box1">box1</div>
<div id="box2">box2
<div>
<div id="box4">box4</div>
</div>
</div>
<div id="box3">box3</div>
CSS:
#box1 {
width: 100%;
height: 40px;
position: fixed;
top: 0;
left: 0;
background: green;
z-index: 5;
}
#box2 {
height: 300px;
position: relative;
background: yellow;
}
#box3 {
height: 100%;
width: 100%;
left: 0;
top: 0;
position: fixed;
background: black;
opacity: .8;
z-index: 10;
}
#box4 {
left: 20px;
top: 20px;
right: 20px;
bottom: 20px;
position: fixed;
background: blue;
z-index: 11;
}
In every other browser, the #box4 (the blue one) appears on the top of the other elements unless I give a z-index property to one of it's anchestors. This is the expected result.
In Android's default browser (tested on 4.1) the #box4 lies under the #box1 and #box3.
Does anybody know a CSS workaround to fix it?
Thx!
A workaround for a similar problem from this thread is to apply
-webkit-transform:translateZ(0);
to #box4.
You have to apply the above mentioned workaround on the parent element or elements of the #box4, along with applying the -webkit-transform:translateZ(0); to the #box4 like this:
#box1, #box2{ /*parent*/
-webkit-backface-visibility: hidden; /* Chrome, Safari, Opera */
backface-visibility: hidden;
}
#box4{ /*child*/
-webkit-transform:translateZ(0); /* Chrome, Safari, Opera */
transform:translateZ(0);
}

I am trying to over lap a div on another div by using css, while background should become blur, like modal pop up show.
But the background of modal pop is still getting displayed through the modal pop up.
As u can see background is visible through the modal pop up!!
I have setted z-index of pop up more than the background
CSS:
.MoreDetails
{
background-color: #000;
z-index: -1;
width: 100%;
height: 100%;
top: 0px;
left: 0px;
position: fixed;
display: block;
opacity: 0.7;
z-index: 100;
text-align: center;
}
.tblView
{
position: fixed;
top: 10%;
left: 30%;
z-index:1;
opacity: 2.0;
}
My design:
<div id="MoreDetails" class="MoreDetails" >
<div id="tableDetails" class="tblView">
</div>
</div>
Child element cannot be stacked below parent element, even by using z-index.
Use z-index for maintaining stack level of absolute positioned elements that are siblings.

HTML
<div class="wrapper">
<div id="MoreDetails" class="MoreDetails" >
<div id="tableDetails" class="tblView">
</div>
</div>
<div id="tableDetails2" class="tblView2">
</div>
</div>
CSS
.MoreDetails
{
/*background-color: #000;*/
background-color: rgba(0,0,0,0.8);
z-index: -1;
width: 100%;
height: 100%;
top: 0px;
left: 0px;
position: fixed;
display: block;
/*opacity: 0.7;*/
z-index: 100;
text-align: center;
}
.tblView
{
position: fixed;
top: 10%;
left: 30%;
z-index:1;
opacity: 1;
background-color: red;
height: 100px;
width: 100px;
}
.tblView2
{
position: fixed;
margin:auto;top:0;bottom:0;left:0;right:0;
z-index: 101;
opacity: 1;
background-color: red;
height: 100px;
width: 100px;
}
The biggest issue is that you're nesting the tableDetails inside the MoreDetails div. Any opacity or z-index you apply to tableDetails will affect MoreDetails. Another approach might be to use the ::before pseudo class on tableDetails and position the two with CSS.
Some other tips:
Don't share id and class names. Using MoreDetails as both an id and
a class may end up breaking things as you progress.
opacity can
only have a value from 0 - 1.
Hope this helps! Good luck!
What I am trying to is have a header image centered on the top with a different color background on either side, dynamically filling the rest of the page. The structure would look like this:
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Center"></div>
<div id="Header_Right"></div>
</div>
The Header_Center is of 960px and the Header_Left and Header_Right should fill either side of the image to the edge of the page and change width as the page width changes.
I can not get the CSS to work properly.
I assume you want those 3 divs to fill each with different content, the outsides filled fluidly or multiline. Otherwise the answer could be much 1) more simple. I also assume that the center div defines the total height of the header.
Given these two assupmtions, still a few different scenarios are thinkable of which I will give 4 examples from which you can choose the best fitting solution.
The HTML is exactly yours.
The CSS looks like:
#Header_Container {
width: 100%;
position: relative;
}
#Header_Left {
position: absolute;
left: 0;
right: 50%;
margin-right: 480px;
}
#Header_Right {
position: absolute;
left: 50%;
right: 0;
margin-left: 480px;
top: 0;
}
#Header_Center {
width: 960px;
position: relative;
left: 50%;
margin-left: -480px;
}
Now, you could change behaviour of left and right with a few extra styles:
height: 100%;
overflow: hidden;
See demonstration fiddle.
1) When the sides may be partially invisible outside the browser window (in case which you would align content in de left div to the right, and vise versa), then I suggest the solution in this fiddle demo which does not require absolute positioning at all so that any content below the header is properly cleared in all circumstances.
You must fix it using padding and box model + position : relative - it can be done without HTML Change
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
And CSS ( 100px is for example )
#Header_Container{ overflow: hidden; height: 100px; }
#Header_Container *{ box-sizing: border-box; height: 100%; }
#Header_Left{ width: 50%; padding-right: 480px; }
#Header_Right{ margin-left: 50%; width: 50%; padding-left: 480px; position: relative; top: -100% };
#Header_Center{ margin: 0 auto; width: 960px; position: relative; top: -200%; }
Example is here http://jsfiddle.net/ZAALB/2/
EDITed incorrect example
If I got you right then this might be a possible solution.
#container {
width: 100%;
height: 150px;
}
#left {
position: absolute;
left: 0;
width: 50%;
height: 150px;
background-color: #FF0000;
}
#right {
position: absolute;
right: 0;
width: 50%;
height: 150px;
background-color: #0000FF;
}
#center {
position: absolute;
left: 50%;
margin-left: -480px;
width: 960px;
height: 150px;
background-color: #888888;
}
#left basically says that the element will be positioned absolute and attached to the left side with a width of 50%. Same applies to #right just for the right side.
#center positions the element absolute pushed 50% to the left and then with a negative margin of width/2 which in your case would be 480px to position it in the center.
The order of the elements in the HTML is important for this hack.
<div id="container">
<div id="left"></div>
<div id="right"></div>
<div id="center"></div>
</div>
The #center DIV must be the last element if you don't want to work with z-indexes.
Here's a fiddle to test it.
HTML:
<div id="Header_Container">
<div class="Header_Side" id="Header_Left"></div>
<div class="Header_Side" id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
CSS:
#Header_Container {
position: relative;
width: 100%;
}
#Header_Container > div {
height: 158px; /* height of the image */
}
.Header_Side {
position: absolute;
width: 50%;
}
#Header_Left {
left: 0;
background-color: blue;
}
#Header_Right {
left: 50%;
background-color: green;
}
#Header_Center {
position: relative;
width: 158px; /* width of the image */
margin: 0 auto;
background-image: url('...');
}
Also see this example.
This works, but you need to change your HTML: http://jsfiddle.net/gG7r7/1/
HTML
<div id="header_background_container">
<div id="header_left"></div>
<div id="header_right"></div>
</div>
<div id="header_content_container">
<div id="header_content"><p>Content goes here</p></div>
</div>
CSS
#header_content_container {
position:absolute;
z-index:1;
width: 100%;
height: 100%;
}
#header_content {
width: 960px;
margin: 0 auto;
background: red;
height: 100%;
}
#header_left {
background: white;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
#header_right {
background: black;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
