How can I get my :before selector behind its box and in front of containing boxes backgrounds? I'm trying to make paper curl effect but I can't get the :before selector where it must go. I made a jsfiddle to illustrate my problem. And here are the codes:
HTML:
<body>
<div class="wrapper">
<div class="content">
<div class="paper">Lorem ipsum dolor sit amet...</div>
</div>
</div>
CSS:
body {
background-color: #ddd;
}
.wrapper{
width: 960px;
background-color: #fff; /* The :before selector seems to hide behind this */
margin: 0px auto 0px auto;
overflow: auto;
font-size: 18px;
line-height: 1.4em;
word-spacing: 0.05em;
letter-spacing: 0.01em;
}
.content {
width: 700px;
margin: 160px 10px 10px 120px;
float: left;
}
.paper {
background-color: #fff;
position: relative;
border: 1px solid #777;
width: 600px;
height: 300px;
margin: 30px auto;
}
.paper:before {
content: "hallo";
width: 300px;
height: 100px;
background-color: #777;
position: absolute;
top: 200px;
left: -100px;
z-index: -1;
}
I need to get the :before selector to appear between "content" and "paper" divs. Any ideas?
You need to play with z-index. Check the DEMO first.
Here is the modify CSS.
.content {
width: 700px;
margin: 160px 10px 10px 120px;
float: left;
position:relative; /*Added Line*/
z-index: 1; /*Added Line*/
}
.paper:before {
content: "hallo";
width: 300px;
height: 100px;
background-color: #777;
position: absolute;
top: 200px;
left: -100px;
z-index: -1; /*Added Line*/
}
I made an example in the jsfiddle with your elements. See if this is want you want
http://jsfiddle.net/nGx5Q/
<body>
<div class="wrapper">
<div class="content">
<div class="paper">Lorem ipsum dolor sit amet, consectetuer adipiscing elit...</div>
</div>
</div>
</body>
body {
background-color: #ddd;
}
.wrapper {
width: 960px;
background-color: #fff; /* The :before selector seems to hide behind this */
margin: 0px auto 0px auto;
overflow: auto;
font-size: 18px;
line-height: 1.4em;
word-spacing: 0.05em;
letter-spacing: 0.01em;
position:relative;
}
.content {
width: 700px;
margin: 160px 10px 10px 120px;
float: left;
background: #e7e7e7;
position: relative;
z-index: 999;
}
.paper {
background-color: #fff;
position: relative;
border: 1px solid #777;
width: 600px;
height: 300px;
margin: 30px auto;
}
.paper:before {
content: "hallo";
width: 300px;
height: 100px;
background-color: #777;
position: absolute;
top: 200px;
left: -100px;
z-index: -1;
}
Z-index.
Change:
.paper:before {
z-index: -1;}
To
.paper:before {
z-index: 1;}

I'm currently working in a final assignment for a class. I need to create a basic webpage (actually, the main goal of the assignment is to learn to use the local storage) but i got stuck on a very early stage of the making (i'm pretty novice in this). I've been using fixed divs for the main structure of the webpage and now idk how to add more content. i tried inherent position but everything went wrong.

thanks for all the patience
I think you may have misunderstood the fixed position. As it is, you can add more content perfectly well in your site: try setting .new { height: 2000px; background: orange;} and you'll see the orange wall does appear and the site scrolls. One thing that might be misleading you is because your header is also fixed, so any content you do add (an <h1> for example) is going to go under it.
In any case, because the banners are fixed, their position is relative to the screen, so they "go down" as you scroll, and they'll be in front of any content you add.
I don't understand what led you to set them fixed in the first place, but it's probably not a good idea. Try taking that out, give the ejemplo pictures a fixed height and let it scroll (try setting you header to sticky rather than fixed). When you're done with your homework, try researching CSS positions a bit more.
I would like to design a border like below picture. But I am running out of ideas about how to do it.
https://codepen.io/szn0007/pen/VRGPyE
div.about-me h2{
color: #000;
border-bottom: 1px solid #efefef;
width: 20%;
margin: 0 auto;
padding: 20px;
}
THank you in advance.
Luckily with CSS you have access to two pseudo elements on every container. I added the Asterix to one of the pseudo elements :after and the line to another :before.
For example:
.fancy-underline {
position: relative;
display: inline-block;
}
.fancy-underline:before {
content: '';
position: absolute;
top: calc(100% + 10px);
left: 0;
width: 100%;
height: 1px;
background: grey;
}
.fancy-underline:after {
content: '*';
position: absolute;
top: 100%;
left: 50%;
transform: translateX(-50%);
background: #fff;
}
<h2 class="fancy-underline">About Me</h2>
try this out:
<div class="about-me">
<h2>About Me</h2>
<p>*</p>
</div>
css:
div.about-me{
width: 100%;
text-align: center;
}
div.about-me h2{
color: #000;
border-bottom: 1px solid #efefef;
width: 20%;
margin: 0 auto;
padding: 20px;
}
p {
font-size: 50px;
transform: translatey(-72px);
}
I am facing a typical situation. I am trying to practice dropdown menu in CSS. Here, the child div .dropdown (grey colored) appears whenever the parent div .content-small (green colored) is hovered upon. Please note, that I have used the .max-width property for all div's because I want all the div's to scale down/up whenever the browser window is scaled.
Now, what I want to do is that I want to increase the max-width of the child div dropdown. But whenever I try to enter a value above 50px, nothing happens. The width DOES NOT increases.
I know that this can be resolved by replacing max-width with only width in the .dropdown class. But if I do that, then the child div dropdown will not scale with the browser window. So in any case, I have to use .max-width property for all divs.
I also don't want to use media queries at this stage. In totality, this is what I am looking for:
I want to increase the width of the dropdown child div .dropdown, I also want it to be scaled along with the browser windows like all other div's (max-width)
I don't want to use media queries at this stage, since I am trying to practice with plain CSS
I don't mind if the .dropdown div DOES NOT remain the child of the parent .content-small (if a possible solution needs it that way)
Would appreciate a solution for this.

Hopefully this does not interfere with what you are trying to accomplish, but what about restructuring your code a little bit:
HTML
<div class="wrapper">
<div class="content">
<div class="content-small">Home</div>
<div class="container" style="height:60px;padding-top:10px;">

}

margin-left: auto;

}
.content-small:hover + .container, .container:hover{

}
.container{visibility:hidden;display: inline-block;
max-width: 100px;
width: 100%;}
.dropdown {
background-color: rgba(214,214,214,1);
border: 3px solid rgba(255,0,0,1);
max-width: 100px;
height: 100%;
max-height: 50px;
position: relative;
margin-right: auto;
margin-left: auto;
top: 5px;
}
And here is:
UPDATED JS FIDDLE
[EDIT]
The + in the css select is saying to look for elements after the first criteria. So, in this case, the css is saying, when you hover over .content-small, it then targets the element AFTER .content-small with .dropdown and applies the css to it. Although it is not the most clear, here is a link of some documentation on css selectors
[SECOND EDIT]
I changed the code above to wrap the dropdown in a container and then set it so on container:hover it alters the visibility of .dropdown the same way, making it persist as visible if you are hovering over either. The reason I had to introduce a container is to give it that spacing between .dropdown and .content-small - which you can see I did with padding-top: and not margin-top: because margin would not have worked with the :hover
when you tell: width:100%; to an absolute child, it takes innerwidth and won't mind the borders,why should it overflow :) ?
You may size it with coordonates like you did for left, use right as well and drop the width:100%;
max-width will still be efficient and you may use margin:auto as well if you wish.

just practicing with css dropdown. In the following code, the .container div (blue colored one) contains the child dropdown div .dropdown (green colored one, I have disabled this color to avoid confusion). The container div is perfectly horizontally aligned to its above div .content-small (red colored one). Since I want the position and margins of all the div's to be mantained whenever I scale down the browser window, I used left: 41.66%; in percentage so that the container div should stay aligned to its top red div.
The container div stays aligned, but whenever the window is scaled down to lowest size, the container div shifts slightly to the right. PLEASE see the attached screenshot. Why is that?

That's because you're saying left: 41.66%;, which is not an accurate way to center. Instead, use this:
CSS
.container {
margin-left: auto;
margin-right: auto;
left: 0;
right: 0;
}
*{
box-sizing:border-box;
}
html,body {
margin: 0px;
height: 100%;
width: 100%;
left: 0px;
top: 0px;
background-color: rgba(0,0,0,1);
padding: 0px;
}
a {
color: rgba(0,0,0,1);
text-decoration: none;
}
a:hover {
color: rgba(0,0,255,1);
}
.wrapper {
height: 600px;
max-width: 960px;
margin-left: auto;
left: 0px;
top: 0px;
background-color: rgba(204,204,204,1);
margin-right: auto;
position: relative;
padding: 0px;
margin-top: 0px;
}
.content {
position: relative;
box-sizing: border-box;
height: 100%;
max-height: 200px;
max-width: 600px;
background-color: #FFF;
margin-right: auto;
margin-left: auto;
margin-top: 0px;
left: 0px;
right: 0px;
font-size: 32px;
text-align: center;
border: 3px solid rgba(0,0,0,1);
border-radius: 15px 15px 0px 0px;
width: 100%;
}
.content-small {
max-width: 100px;
height: 100%;
max-height: 50px;
background-color: rgba(255,0,0,1);
position: relative;
margin-right: auto;
margin-left: auto;
border: 3px solid rgba(0,0,0,1);
top: 5px;
margin-top: 10px;
}
.content-small:hover + .container, .container:hover{
visibility: visible;
}
.container{
visibility: visible;
height: 100px;
max-width: 100px;
background-color: rgba(204,102,255,1);
position: absolute;
margin-left: auto;
margin-right: auto;
left: 0;
right: 0;
}
.dropdown {
/* [disabled]background-color: rgba(0,255,0,1); */
/* [disabled]border: 3px solid rgba(255,0,0,1); */
width: 100px;
height: 100%;
max-height: 50px;
position: relative;
margin-right: auto;
margin-left: auto;
top: 3px;
}
<div class="wrapper">
<div class="content">

<div class="container">

I need when you hover a mouse on one div other div with parametres appear from below and these both divs have common border.
Now I have border only on first div. It looks like first div don't contain second, but in html code div with parametres is beetwen of first.
What is wrong?
.item {
width: 220px;
height: 300px;
margin: 10px 3px;
float: left;
position: relative;
}
.item:hover .item_inner {
position: absolute;
top: 0;
left: 0;
z-index: 10;
background: #fff;
box-shadow: 0 1px 14px rgba(0,0,0,0.3);
height: 100%;
}
.item_param {
display: none;
text-align: left;
padding: 0 5px;
margin: 10px 0;
background-color: #f3f3f3;
}
.item_inner{
width: 100%;
height: 100%;
position: relative;
padding-bottom: 5px;
border: 1px solid green;
}
.item_inner:hover .item_param {
display: block;
top: 100%;
width: 100%;
position: absolute;
}
<div class="item">
<div class="item_inner">
TEXT
<div class="item_param">
<p>Parametres</p>
<p>Parametres</p>
<p>Parametres</p>
</div>

.item_inner:hover .item_param {

}
