How to make such a scroll of content? - javascript

Please help me to style the scrolling of content using react and scss like this:
So that when the scrolling elements overlap each other, they have something like a parallax style.

a simpler solution would be something along the lines of:
.contentDivContainer {
position: absolute;
left: 100px;
width: 200px;
height: 200px;
}
.contentDivs {
background-color: lightpink;
font-size: 18px;
margin: 20px;
}
.contentDivs:nth-child(2n) {
background-color: lightblue;
}
.windowDivs {
position: fixed;
width: 200px;
height: 200px;
left: 100px;
}
.windowDivs2 {
top: 300px;
}
.windowDivsBlank {
top: 0px;
z-index: 2;
background: white;
height: 50px;
}
.windowDivsBlank2 {
top: 250px;
z-index: 2;
background: white;
height: 50px;
}
.windowDivsBlank3 {
top: 500px;
z-index: 2;
background: white;
height: 50px;
}
<div class='windowDivs'></div>
<div class='windowDivs windowDivsBlank'></div>
<div class='windowDivs windowDivs2'></div>
<div class='windowDivs windowDivsBlank2'></div>
<div class='windowDivs windowDivsBlank3'></div>
<div class="contentDivContainer">
<div class='contentDivs'>
ONE - Scroll Up and Down this page to see the parallax scrolling effect. This div is just here to enable scrolling. Tip: Try to remove the background-attachment property to remove the scrolling effect.

Overlay the Contents of a DIV

I am trying to overlay 2 DIV's in my main parent DIV:
I want to overlay the the second div over on top of the first one. I have a problem overlaying it as I cannot keep it in the middle of the screen.
I have tried this to overlay:
The overlay works fine here, but my container is no longer center when I do this. How can I overlay and keep it center ?
div {
border: 5px solid red;
}
#first {
position: absolute;
z-index: 1;
border-color: orange;
}
#second {
position: absolute;
z-index: 2;
border-color: green;
}
<div id="container" class="container text-center">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
Here is what you need to do (see width of both divs and text-align properties):
You can give them background color to see z-index works perfectly :)
#first {
text-align: center;
height: 300px;
width: 100%;
position: absolute;
z-index: 1;
}
#second {
text-align: center;
height: 300px;
width: 100%;
position: absolute;
z-index: 2;
}
<div id="container" class="container text-center">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
When you position absolute, the positioned element is taken out of the document flow and positioned relative to the next highest parent element that is not the default position, i.e. not position: static;
The following will cause the absolute positioned children to stay within the containing div:
#container {
position: relative;
}
Your container's text is no longer centered because you have removed its children from the document flow. In essence, it has no content and collapses, and therefore, has no width to which to align the text.
One thing you could do is set the container to position: relative and full-width (i.e. width: 100vw), then set its children to width: 100%.
Then the inner divs will take on the width of their parent.
See this working JSFiddle.
#container {
position: relative;
width: 100%;
height: 100px;
background-color: yellow;
display: flex;
justify-content: center;
align-items: center;
}
#first{
position: absolute;
}
#second{
position: absolute;
}
<div id="container" class="container">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
Your main issue is that the divs will not have any relative width to the parent div.
Therefore the text is still technically "centered" in each corresponding div because they're inheriting text-align: center from the container div.
However, the divs' widths will automatically be as wide as they needs to be (i.e. to fit the text, in this case).
You can remedy this one of two ways:
Force the divs to be centered
Give both divs the following (extra) CSS:
left: 50%;
width: 100%;
margin-left: -50%;
This will literally center them in their parent div.
or
Force the divs to be the same size as their parent
Give both the divs the following (extra) CSS:
top: 0;
bottom: 0;
left: 0;
right: 0;
This sets the divs to span their entire parent's height and width.
In both situations, you might need to make the .container class use position: relative, in order for the child divs to have something to be absolute to.
If you're using Bootstrap, there is no need to worry about this, as .container class already has this applied.
Hope one of these solutions helps you :)
Try this style:
#first,
#second {
left: 50%;
transform: translate(-50%, 0);
}
div {
border: 5px solid red;
}
#first {
position: absolute;
z-index: 1;
border-color: orange;
}
#second {
position: absolute;
z-index: 2;
border-color: green;
}
#first,
#second {
left: 50%;
transform: translate(-50%, 0);
}
<div id="container" class="container text-center">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>

How can I use toggle("slide") to show a phrase one letter at a time

I am using a `.toggle("slide") function to try and get a piece of text I have to appear as if each letter is sliding in. Unfortunately, it looks as if the text is flying in instead. I tried to squeeze the margins in tight, so that it would start at a closer place, but it still looks as if it is flying in from the left side.
Is there a better way to do this, so it looks as if the letters are sliding in without "flying in"?
$("#home-learn").toggle("slide");
#blue {
background-color: #0085A1;
width: 100%;
height: 300px;
}
#home-learn {
color: #FFF;
display: none;
text-align: center;
position: relative;
margin: 0 40%;
top: 50%;
font-size: 2.3em;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="blue">
<div id="home-learn">Learn more...</div>
</div>
For the effect you want, put a div inside your container. Make the div position absolute, make it 100% the height and width of the container, and make it the same background color as the main background. Make the div's z index higher than the container so the div sits over the text like a curtain. Then use toggle() to slide the curtain to the right exposing the text underneath.
Note that this uses jQuery UI, without it, you can't make toggle() slide to the right like this needs.(at least to my knowledge you cant). If you dont want to use jquery UI, you could use .animate() instead of toggle()
$("#curtain-div").toggle("slide", {
direction: "right"
}, 3000);
#blue {
background-color: #0085A1;
position: relative;
width: 100%;
height: 300px;
}
#home-learn {
color: #FFF;
text-align: center;
position: relative;
top: 50%;
font-size: 2.3em;
}
#curtain-div {
width: 100%;
height: 100%;
position: absolute;
background-color: #0085A1;
top: 0;
left: 0;
z-index: 10;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
<div id="blue">

Responsive code ceases to work after manually toggling a DIV

I have two divs. I want the left div to hide and show automatically according to the window size, i.e. I want it to be responsive.
On the other hand, I want to hide/show the left div manually if necessary. I added a black separator in the middle. When the separator is clicked the left div hides and the right div takes the whole width.
Until now, everything is ok.
BUT. When I hide/show the left div manually, it ceases to react to the responsive code.
Please check this JSFiddle and lend me some help.
Thank you very much.

Have a play with having two classes for identifying whether something is hidden or not i.e. desktop and mobile. You can then check whether its actually hidden with is(':hidden') and respond accordingly.
Check this fiddle for a quick demo http://fiddle.jshell.net/tmx3p6ts/31/
Read this: getbootstrap.com/css/#grid You can use the grid system to make a page like you have, but when the screen is getting to small, you can getbootstrap.com/css/#responsive-utilities use this link to know when to hide things.
So to help you maybe a step in the right direction:
<div class="container">
<div class="col-sm-4 hidden-xs">
This is the left div.
</div>
<div class="col-sm-8 col-sm-12">
This is the left div.
</div>
</div>
Something like this should work. Check out this fiddle: Fiddle with bootstrap
You can adjust the classes to any style you want.

Darken area around jQuery draggable div?

I'm looking for a way to darken all of the area within a container except for a transparent child div. This div is draggable, so the dimmed area would have to move with it. Does anyone know of a way to achieve this using jQuery/CSS? Here is a picture of the effect I am trying to achieve:
EDIT: SOLVED
See #Robby Cornelissen's answer
Could do something like this fiddle. It relies on an absolutely positioned viewport element with a fixed background. If you click the viewport element, you'll see that it moves while the background stays fixed.

<div class="back">
<div class="overlay">

background-attachment: fixed;
background-position: 0,0;
}
.back {
width: 1024px;

.front {
position: absolute;

.overlay {
