I am using this code http://cssdeck.com/labs/pa0yqlki that displays a canvas covering the size of the browser's window.
I am able to display content on top of the canvas (by using absolute positioning and z-index: -1)
What I am not able to do is add content AFTER the canvas.
Once the canvas ends, and so does the window, I want to have an <h1> lets say. So a scroll bar should appear when the page is loaded I should be able to scroll a bit more so that I see the <h1>.
Any ideas?
Okay, thanks to markE's reply I was able to achieve what I wanted.
[...] <canvas> </canvas>
<h1 id="myText"> Text </h1> [...]
this is the part of my HTML. The "myText" will be displayed under the canvas based on the size of the window.
To achieve that I added the following code in the CSS.
#myText
{
padding-top: 100vh;
}
You can achieve this with playing with CSS positions;
Try something like this:
<div>
<canvas width="300" height="200" class="custom-canvas" />
<div class="text">
<div class="main">20 %</div>
<div class="head">Completed</div>
</div>
</div>
SCSS:
.custom-canvas{
position: relative;
clear: both;
width: 450px;
height: 200px;
}
.custom-canvas {
.text {
bottom: 13px;
position: absolute;
left: 6px;
right: 0;
text-align: center;
}
.head {
margin-top: 14px;
}
}
Play with left,right,top and bottom to achieve the exact position.

Hi i'm learning html/css and javascript and I think I'm having an issue with my html structure. Basically what I want to do is that my particles animation stays on the website while scrolling the page. I have a Javascript file that does a getElementById('particles') to run the canvas on a div but it only stays on the first page.
I tried to move the "particles" div as a main div that will contain all the sections but it didn't work.
Here's the repository of the files if anyone is interested: https://github.com/DanielVillacis/DanielVillacis.github.io
Here's my html structure :
document.addEventListener('DOMContentLoaded', function() {
particleground(document.getElementById('particles'), {
dotColor: '#FFFFFF',
lineColor: '#FFFFFF'
});
var intro = document.getElementById('intro');
intro.style.marginTop = -intro.offsetHeight / 2 + 'px';
}, false);
html,
body {
width: 100%;
height: 100vh;
}
canvas {
display: inline-block;
vertical-align: baseline;
}
header,
section {
display: block;
}
#particles {
width: 100%;
height: 100vh;
overflow: hidden;
position: relative;
}
.container {
scroll-snap-type: y mandatory;
overflow-y: scroll;
height: 100vh;
}
section {
height: 100vh;
width: 100%;
display: inline-block;
scroll-snap-align: start;
}
<body>
<div class="container">
<main role="main">
<section class="intro">
<div id="particles">
<header class="splash" id="splash" role="banner">
<div id="intro">
</div>
</header>
</div>
</section>
<section class="AboutMe">
<div class="introduction">
</div>
</section>
<section class="box">
<div class="projectContainer">
</div>
</section>
<section class="Contact">
<h2 class="ContactTitle">Contact</h2>
<div class="contactLinks">
</div>
</section>
</main>
</div>
</body>
Use the CSS position: fixed; property.
With position set to fixed, your canvas is positioned relative to the viewport and hence would remain even while scrolling.
.pg-canvas {
display: block;
position: fixed;
top: 0;
left: 0;
pointer-events: none;
width: 100%;
height: 100vh;
}
You have put the particles (which are shown on a canvas) into a section which will scroll out of view.
The particles library you are using places this canvas just before the element you have given it, which has id particles.
You can fix just the canvas by adding position: fixed to the canvas selector in your style sheet (watch out if you have other canvases to give a more definite selector).
This will work in many cases to fix the canvas with the particles to the viewport. But note this description from MDN
The element is removed from the normal document flow, and no space is
created for the element in the page layout. It is positioned relative
to the initial containing block established by the viewport, except
when one of its ancestors has a transform, perspective, or filter
property set to something other than none (see the CSS Transforms
Spec), in which case that ancestor behaves as the containing block.
(Note that there are browser inconsistencies with perspective and
filter contributing to containing block formation.) Its final position
is determined by the values of top, right, bottom, and left.
You are OK at the moment because you move intro with top but if that were a translate you’d have to put the canvas out of intro.
So I have this carousel from http://kenwheeler.github.io/slick/. I decided with my carousel that once you click the image-a video appears. Well I want this video to load into a Modal Image-with a closeout function. The first line of code for div id....is the image onced clicked the video appears. The rest below it I'll just copy and paste the first part. (Repeat of the same image/video four times-until I decide to switch things out)
<section class="center slider">
<div id="video" style="display:none;"><iframe width="560" height="315" src="https://www.youtube.com/embed/36_e3qbYhEs" frameborder="0"></iframe></div>
<a href="javascript:document.getElementById('video').style.display = 'block'; document.getElementById('videopic').style.display = 'none'; void(0);">
<img id="videopic" src="images/350x300.png" alt="Video Picture" /></a>
<div>
<img src="http://placehold.it/350x300?text=2">
</div>
<div>
<img src="http://placehold.it/350x300?text=3">
</div>
<div>
<img src="http://placehold.it/350x300?text=4">

I have the JS and CSS all working fine I just can't implant a function where you click the image the "image(video)" will open in a new window. Sorry about my wording. I am beginner and learning as I go. I know what I want it to do but can't figure out how.
Please let me know if I need to provide anything further.
I think the term you're looking for that might help you in Googling would be that you want your video to open in a lightbox.
Answering specifically how to do this in your particular circumstance is too broad for this site, even if you give us more code to look at. But generally the way you can accomplish this is to use JavaScript to toggle a class on one or more elements when your slideshow images are clicked, and adding that class would trigger the video to show up, while clicking the exit button would remove the class so things go back to their original appearance.
Here is a really basic example, but you can basically take this concept and make it as simple or complicated as you want. You could, for example, toggle a class on the html or body tag of your page and then adjust the CSS of a bunch of stuff on the page based on whether that class is applied.
If you're using jQuery, there are plugins designed exactly for this purpose that will automatically give you a ton of settings to do things like automatically size and perfectly center your lightbox in the viewport and take care of mobile functionality and whatnot. Fancybox and Colorbox are a couple examples.
var lightboxImg = document.getElementsByTagName('img')[0];
lightboxImg.addEventListener('click', function(){
this.parentNode.classList.toggle('lightbox');
});
document.getElementById('exit').addEventListener('click', function(){
lightboxImg.parentNode.classList.toggle('lightbox');
});
/* relevant stuff */
#iframe {
display: none;
position: absolute;
top: -100px;
left: -100px;
}
#exit {
position: absolute;
top: 10px;
right: -290px;
padding: 5px;
background-color: white;
}
section div.lightbox #iframe {
display: block;
}
img:hover, #exit:hover {
cursor: pointer;
}
/* just for display purposes */

height: 300px;
background-color: gold;
position: relative;
left: calc(50% - 200px);
top: calc(50% - 150px);
}
section div {
position: relative;
top: 50px;
left: 50px;
width: 300px;
height: 200px;
}

I found this codepen showcasing a zoom and pan effect for images. As far as I can tell, the code works by assigning a background-image to each div based on its data-image attribute. Is there any way that I can do this on a direct img tag instead of a div with a background-image?
EDIT: This is the kind of mark-up I'm talking about. A container div with an actual img tag inside of it.
Take a look at the CodePen now.
Think i got it to look kinda like you want it
<div class="tiles">
<div data-scale="1.1" class="product-single__photos tile" id="ProductPhoto">
<img class="photo" src="//cdn.shopify.com/s/files/1/1698/6183/products/bluza_dama_39377a_large.jpg?v=1487178925" alt="Last Skirt" id="ProductPhotoImg">
</div>
</div>
You can play with the margin to adjust the image position
div{
width:100%;
height:200px;
overflow:hidden;
}
img{
width:100%;
margin:0%;
transition:0.5s;
}
img:hover{
width:120%;
margin:-10;
}
<div>
<img src="https://cdn.pixabay.com/photo/2015/07/06/13/58/arlberg-pass-833326_960_720.jpg">
</div>
Absolutely. It would involve giving the elements some CSS:
div.product-single__photos {
position: relative;
overflow: hidden;
}
div.product-single__photos > img {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: auto;
}
And have the Javascript manipulate the <img>'s width, height, top and left properties.
I want to have a long page, with a fixed top 100px div, and a fixed 50px bottom div. However, I want the bottom div to scroll as you scroll down the page.
Its hard to explain, but the best example of this is on the front page of PayPal.com
On the first page load, the bottom div looks like it is fixed, and as you adjust the height of the browser window, that div stays at the bottom. Yet as you scroll down the page it is not fixed.
Can anyone explain how they have done this? I am trying to re-create something similar, but cant see how they have managed it.
As far as I can see they have this html...
<div id="fixed-top">
<header class="table-row">
// header content
</header>
<div class="table-row table-row-two">
// Video content
</div>
<div class="table-row">
//bottom content
</div>
</div>
And this CSS...
#fixed-top {
height: 100%;
width: 100%;
display: table;
position: relative;
top: 0;
left: 0;
z-index: 1;
}
.table-row {
display: table-row;
}
But that alone doesn't do it. I also can't see any js thats getting window height and applying it to the main fixed div.
Help! :)
EDIT:
Have just found a way to do it with javascript, controlling the height of the middle row using the window height, minus the 150px for the header and third row.
jQuery(document).ready(function(){
$('div.table-row-two').css({'height':(($(window).height())-150)+'px'});
$(window).resize(function(){
$('div.table-row-two').css({'height':(($(window).height())-150)+'px'});
});
});
But saying that, Zwords CSS only method seems like a winner.
From what I understand, you are looking for something like a sticky footer. So basically if the content is not enough, the footer should go sit at the bottom like its fixed, but if content comes in, it should scroll down like other content.
Try this - http://css-tricks.com/snippets/css/sticky-footer/
First off, you'll need to set the height of the body and html tag, otherwise the table won't take the full screen. Then I altered your code, made it a bit easier.
HTML:
<div id="fixed-top">
<header>
// header content
</header>
<div>
// Video content
</div>
<div>
//bottom content
</div>
</div>
CSS:
html, body {
margin: 0;
padding: 0;
height: 100%;
min-height: 100%;
}
#fixed-top {
display: table;
width: 100%;
height: 100%;
}
#fixed-top > * { /* makes all the direct children of #fixed-top a table row*/
display: table-row;
background: lightblue;
}
#fixed-top > *:nth-child(1) {
background: lightgreen;
height: 40px;
}
#fixed-top > *:nth-child(3) {
background: lightgreen;
height: 25%;
}
You can either set the height to a fix height (in px) or percentages. If you only give two of the three rows a height, the third one will automaticly fill up the rest space.
Also, check this demo.

You can do this easily with jQuery using $(window).height() and subtracting your footer/header's heights. See Fiddle for an example.
I'm using Telerik Radeditor which is rich text area and the editor content is an iframe, something like below:
<iframe frameborder="0"
src="javascript:'<html></html>';"
style="width: 100%; height: 100%; margin: 0px; padding: 0px;"
title="hello world"
id="contentIframe"></iframe>
My goal is to display the "hello world" tooltip when a user mouse hover the iframe area.
As you can see I put "title" attribute but it is not showing up.
To mimic the tooltip behavior I tried placing overlay div and title which worked but then I lost mouse control because of the overlay div.
I also desperately tried putting title in the iframe body but then I had to click inside of iframe to make it happen which is not the solution.
var iframe_html = $(wrapper).find("iframe").contents().find("html");
$(iframe_html).prop("title", "hello my tooltip 1");
var iframe = $(wrapper).find('iframe');
$(iframe).prop("title", "hello my tooltip 2");
var iframebody = $(iframe).contents().find('body');
$(iframebody).prop("title", "hello my tooltip 3");
I'm using jQuery UI 1.8.16 which does not come with Tooltip capability thus that cannot be an option..
Could anyone help me figure how to show the tooltip?
You are able to assign a title to the iframe but you wont be able to see it in the iframe.. Change the frameborder to "2" and move your cursor to it.. there you go..Title appears...
To see the title on iframe you must set the title of iframe content and not the iframe itself..
just like i've done below..
<iframe frameborder="0"
src="javascript:'<div id=\'hey\' title=\'Hello World\'>Helllo World</div>';"
style="width: 100%; height: 100%; margin: 0px; padding: 0px;position:relative;"
title="hello world"
id="contentIframe">
</iframe>
Alternatively..
using jQuery
$(document).ready(function () {
$("#contentIframe").contents().find("body").attr('title','Hello World');
});
This is a fiddle for your reference..
I just added an iframe to the div in the w3 schools tooltip tutorial (TryIt editor here) and it worked perfectly. To my surprise.
<!DOCTYPE html>
<html>
<style>
.tooltip {
position: relative;
display: inline-block;
border-bottom: 1px dotted black;
}
.tooltip .tooltiptext {
visibility: hidden;
width: 120px;
background-color: #994444;
color: #ffffff;
text-align: center;
border-radius: 6px;
padding: 5px 0;
/* Position the tooltip */
position: absolute;
z-index: 1;
bottom: 100%;
left: 50%;
margin-left: -60px;
}
.tooltip:hover .tooltiptext {
visibility: visible;
}
</style>
<body style="text-align:center;">
<h2>Proof of Concept</h2>
<p>This, cobbled from the W3 schools tutorial on CSS tooltips. I added an Iframe inside the div; one may still interact therewith, yet enjoy full tooltipitude.</p>
<p> So, move the mouse over the text below:</p>
<div class="tooltip">Hover over me
<span class="tooltiptext">Hello World</span>
<iframe height="600px" src="https://imgur.com/a/71J1gQZ" width="600px" ></iframe>
</div>
</body>
