Pseudo element in after starting from center - CSS - html

Following is my code in which I am trying to apply a red color bottom to a div in such a way that it takes 50px left and right margin and then stretch to the max width, but somehow it is moving to the left. Let me know how can I make to appear in center to the bottom of the div with 50px space left from left and right.
Also let me know why the ::after element is creating from the center than from the extreme left. [Refer to the image of its creation].
HTML -
<div class="container">
<h1>This is a simple heading</h1>
<h3>This is only a test description</h3>
</div>
CSS -
.container {
background: #34EACC;
width: 100%;
text-align: center;
}
.container:after {
content: "";
position: absolute;
width: 100%;
margin: 0 50px;
height: 1px;
background-color: red;
}

While defining absolute you also should declare left or right properties if want to position the element
.container {
background: #34EACC;
width: 100%;
text-align: center;
}
.container:after {
content: "";
position: absolute;
width: 90%;
left: 0;
right: 0;
margin: 0 auto;
height: 1px;
background-color: red;
}
<div class="container">
<h1>This is a simple heading</h1>
<h3>This is only a test description</h3>
</div>

Just use left and right properties
.container {
background: #34EACC;
width: 100%;
text-align: center;
}
.container:after {
content: "";
position: absolute;
height: 1px;
background-color: red;
left: 50px;
right: 50px;
}
<div class="container">
<h1>This is a simple heading</h1>
<h3>This is only a test description</h3>
</div>

You can use translate: transform(),
hope this helps :)
.container {
background: #34EACC;
width: 100%;
text-align: center;
}
.container:after {
content: "";
position: absolute;
width: 90%;
left: 50%;
transform: translateX(-50%);
height: 1px;
background-color: red;
}

Text won't absolutely position using CSS?

I am new to CSS and HTML, and I am working on my final project for school.
I am trying to absolutely position some text "Welcome" to a div I've made. For some reason it won't position in relation to the div, I've looked it over 10 times and can't figure out why.
I want the "Welcome" text to sit at the bottom of the welcome div, however when I put bottom:0px; into the CSS, it doesn't position according to its parent container and instead goes 0px from the top of the whole screen.
Here's the code:
#wrapper {
height: 1000px;
margin: 0 auto;
background-image: url(images/background.jpg);
background-size: 100% 100%;
}
#header {
height: 150px;
position: relative;
background-color: red;
}
#welcome {
position: absolute;
bottom: 0;
width: 420px;
height: 100px;
background-color: green;
}
.w {
height: 150px;
position: absolute;
font-size: 64px;
left: 20px;
bottom: 0px;
color: #fff;
}
<div id="wrapper">
<header id="header">
<div id="welcome">
<p class="w">Welcome</p>
</div>
<nav id="main nav"></nav>
</header>
</div>
You are very close. Take the height away from the .w p tag and remove its margin as well:
#wrapper {
height: 1000px;
margin: 0 auto;
background-image: url(images/background.jpg);
background-size: 100% 100%;
}
#header {
height: 150px;
position: relative;
background-color: red;
}
#welcome {
position: absolute;
bottom: 0;
width: 420px;
height: 100px;
background-color: green;
}
.w {
/*height: 150px;*/
margin: 0;
position: absolute;
font-size: 64px;
left: 20px;
bottom: 0px;
color: #fff;
}
<div id="wrapper">
<header id="header">
<div id="welcome">
<p class="w">Welcome</p>
</div>
<nav id="main nav"></nav>
</header>
</div>
The problem, as CalvinNunes pointed out, is that you have a height set on .w div. And, p elements have margin and line-height values by default. You need to remove the margin and set the line-height to 1 or less (.5 makes the text touch the bottom of the green box).
#wrapper {
height: 1000px;
margin: 0 auto;
background-image: url(images/background.jpg);
background-size: 100% 100%;
position: relative;
}
#header {
height: 150px;
background-color: red;
position: absolute;
width: 100%;
}
#welcome {
position: absolute;
bottom: 0;
width: 420px;
height: 100px;
background-color: green;
}
.w {
position: absolute;
font-size: 64px;
left: 20px;
bottom: 0px;
color: #fff;
margin: 0;
line-height: 1;
}
<div id="wrapper">
<header id="header">
<div id="welcome">
<p class="w">Welcome</p>
</div>
<nav id="main nav">
</nav>
</header>
</div>
<!-- End of wrapper-->
If you use absolute on something, related dom element should be relative, absolute or fixed, depending on your needs.
Also check if your absolute element doesn't have some unneeded margins etc.
But in your usage case i don't think that there is absolute needed. you can use bigger paddings for parent element top. Also this can be achieved using flex-end, which will allow dynamic text input.

My floating element disturbs other elements

I have a problem with my brand new html & css sites : I want to have a that opens when hovering on a floating element of itself. The problem is not on animation but on layout. When it's empty, it works well, but when I add content into the , it goes under the floating element. To solve this, I've tried different overflow values as explained here, but of course the part of the whitch is "outside" of it got impacted.
(in this sample, the "menu" is already opened)
section
{
background-color: white;
margin: 10px;
}
.scroll_aside{
overflow-y: auto;
width: 100%;
height: 100%;
}
.aside_left{
width: 70%;
height: 100%;
display: block;
background-color: gold;
position: fixed;
top:0;
}
.aside_left .cote{
position: relative;
top:0px;
right: -80px;
width: 80px;
background-color: orange;
margin-top: 100px;
margin-left:0;
float: right;
}
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="TEST2.css"/>
</head>
<body>
<div class='aside_left'><span class='cote' onclick="openjourney()">Floating on the right</span>
<div class="scroll_aside">
<section style='height: 400px'>Section 1</section>
<section style='height: 800px'>Section 2</section>
</div>
</div>
</body>
</html>
Another thing I've noticed is that when the content is thin enough, it goes to the top....
But what I want, is to have the content taking all the , so going at the top and with width=100%.
Is there a way to do that ?
Thank you in advance....
Instead of float use absolute position:
section {
background-color: white;
margin: 10px;
}
.scroll_aside {
overflow-y: auto;
width: 100%;
height: 100%;
}
.aside_left {
width: 70%;
height: 100%;
display: block;
background-color: gold;
position: fixed;
top: 0;
}
.aside_left .cote {
position: absolute;
left: 100%;
width: 80px;
background-color: orange;
top: 100px;
}
<div class='aside_left'><span class='cote' onclick="openjourney()">Floating on the right</span>
<div class="scroll_aside">
<section style='height: 400px'>Section 1</section>
<section style='height: 800px'>Section 2</section>
</div>
</div>

Keep element aligned to background

So, I'm trying to create a layout where the paragraph tag should always be aligned to a specific part of the background image.
Link with working example https://codepen.io/marcelcruz/pen/BRgaVL
I want the text to be always inside the crystal ball, but once I resize the window the background shrinks, the crystal ball goes up and they're not aligned anymore.
Is there a way of making the background only shrink on both sides, but not on the top and bottom? Some other better approach for this?
This part of the code looks something like this:
* {
padding: 0;
margin: 0;
}
body {
background: url("https://s-media-cache-ak0.pinimg.com/originals/d5/b0/57/d5b057f0816424bf45ab7d7a72deec5a.jpg") no-repeat;
background-size: cover;
height: 100vh;
}
#text {
color: red;
background: yellow;
width: 60px;
position: absolute;
top: 900px;
left: 50%;
}
<div id="main">
<p id="text">TEXT COMES HERE</p>
</div>
Thanks!
This could be done with an <img> tag and relative positioning, example
.container img {
max-width: 100%;
}
.img-container {
display: inline-block;
position: relative;
}
.positioning {
position: absolute;
left: 45%;
bottom: 30%;
background-color: red;
color: white;
padding: 4px;
font-size: 17px;
line-height: 18px;
}
<div id="container" class="container">
<div class="img-container">
<div class="positioning">
Some Text
</div>
<img src="https://s-media-cache-ak0.pinimg.com/originals/d5/b0/57/d5b057f0816424bf45ab7d7a72deec5a.jpg" />

It works, when You set background-size: 100% 100%;

Fixed navbar covered by rest of the page when scrolling down

I would like to have an element looking like a navbar at the top of my website:
It should be fixed, like a navbar. However, as soon as the user scrolls down, it should disappear under the rest of the content:
I tried something like that, where the #title element is the "navbar":
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<div id="title" class="center-align">
<h1>Title</h1>
<h2>Subtitle</h2>
</div>
<div id="showcase" class="center-align">
</div>
</body>
<style>
#title {
position: fixed;
width: 100%;
height: 50vh;
z-index: -1;
}
#showcase {
margin-top: 50vh;
height: 75vh;
background-color: #212121;
}
</style>
</html>
However this is not working, the #title seems to be also affected by the 50vh margin-top (you can see it by setting its z-index to 1 instead of -1).
No need to use z-index
By default sibling are stacking by the order from bottom to top so the 1st child will at the bottom, the last child at the top. See example here:
Example of sibling z-index:
.div1 {
width: 100px;
height: 100px;
background: red;
}
.div2 {
margin-top: -50px;
margin-left: 50px;
width: 100px;
height: 100px;
background: green;
}
.div3 {
margin-top: -50px;
margin-left: 100px;
width: 100px;
height: 100px;
background: aqua;
}
<div class="div1">
div1
</div>
<div class="div2">
div2
</div>
<div class="div3">
div3
</div>
Solution to your problem:
#title {
width: 100%;
height: 100px;
text-align: center;
position: fixed;
top: 0;
}
#showcase {
margin-top: 120px;
height: 90vh;
background: black;
}
<div id="title">
<h1>Title</h1>
<h2>Subtitle</h2>
</div>
<div id="showcase">
</div>
Try change your style with the following css . I made some changes for test purpose.
#title {
position: fixed;
width: 100%;
height: 50vh;
z-index: -1;
background: red ;
top:0;
}
#showcase {
margin-top: 50vh;
height: 275vh;
background-color: #212121;
}
Hope it helps
Here's an example using a fixed navabr and a normal div for the content having a margin-top:
body {
margin:0;
height:100%;
}
.navbar {
width: 100%;
height: 50px;
line-height: 50px;
position: fixed;
background-color: lightblue;
z-index:-1;
}
.content {
width: 100%;
float: left;
height: 1000px;
margin-top: 50px;
background-color: red;
}
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<div class="navbar">
Navbar
</div>
<div class="content">
Content
</div>
</body>
</html>
Add top: 0 to the title id. Like:
#title {
position: fixed;
width: 100%;
height: 50vh;
z-index: 1;
top: 0;
}

Position image over image on two neighbour divs

I want to have a centered box with two images on each side of a box, overlapping. Later, I'll move top image for each box with jquery animate function away from bottom image.
This is my code so far:
html,
body,
#wrapper {
height: 100%;
min-height: 100%;
}
#wrapper {
align-items: center;
display: flex;
justify-content: center;
}
#center {
width: 800px;
border: 1px solid black;
text-align: center;
position: relative;
}
img {
width: 100%;
height: auto;
float: left;
}
#left {
//border:1px solid red;
width: 400px;
float: left;
//position:absolute;
}
#right {
//border: 1px solid green;
width: 400px;
float: right;
//position:absolute;
}
#top {
z-index: 1;
}
#under {
z-index: -1;
}

I have managed to center this box and add one picture for each side (left, right), but when I want to add another picture on either side, that has z-index: -1 it breaks into new line..
Fiddle that is showing problem: https://jsfiddle.net/bjgydLvo/
You need to give your second image a class and position it absolute.
<img class="second" src="http://s32.postimg.org/4vp56ei11/workout_left.jpg" id="under">
.second {
position: absolute;
top: 0;
z-index: 2;
left: 0;
width: 100%;
}
Make sure you position your left element relative too
#left {
width: 400px;
float: left;
position: relative;
}
Remove #under
Working example
https://jsfiddle.net/46pk1vdf/4/
z-index wont work without assigning position..
Updated fiddle : https://jsfiddle.net/bjgydLvo/2/
#under{
z-index:-1;
float: none;
height: auto;
left: 0;
position: absolute;
width: 400px;
z-index: -1;
}
