I have a DIV container in which I have a SVG document (bigger than DIV). In this same container I have another DIV (lets call it DIV#2) that moves over my SVG, to help people locate some feature. When I scroll the container DIV I would like DIV#2 to stay anchored on the same position on my SVG, so as to be coherent my the new position of the selected feature (cf Rect_Follow() function below).
Can someone help me troubleshooting that without the use of jQuery?
Here's a small portion of the code:
CSS:
<style type="text/css">
<!--
div.SVG_container {
height:800px;
width:900px;
margin-top:250px;
overflow:scroll;
}
div.select_div {
position: absolute;
height: 98px;
width: 98px;
background: #CCF;
border: 1px solid #AAD;
text-align: center;
font-size: 10px;
border:1px solid black;
filter:alpha(opacity=60); /* for IE */
opacity:0.6; /* CSS3 standard */
}
-->
</style>
HTML/JavaScript:
<head>
<!-- ... -->
<script type="text/javascript">
function Rect_Follow(obj){
var rect = document.getElementById('arect');
rect.style.top = obj.scrollTop;
}
</script>
</head>
<body bgcolor="white">
<div id="DivCont" class="SVG_container" onscroll="Rect_Follow(this)">
<div id="arect" name="arect" class="select_div"></div>
<object id="aSVG" data="out.svg" style="margin-top:0px;overflow:hidden;" />
</div>
<!-- ... -->
</body>
Add position:relative to .SVG_container, and remove the JavaScript.
I hope this is what you mean.

I am aware I can use background-image: url("www.linktoimage.com/image.png"), in css, to place an image in the background. I also know I can add a javascript file into html with tag. My challenge is how do I apply css characteristics of a background image to my javascript file?
To add some context, the javascript file is a simple animation (randomly bouncing balls, that responds to the screen width and height. I want to place text on top of this as if it was background, but no matter what I do, text will place itself above the script, in a white box, instead of directly on top of my script. Below is the general result of my various attempts:
I would like to place "Welcome" on top of my javascript, as oppose to how it currently appears on top of window with a white background. My css is as follows:
#font-face {
font-family:'HighTide';
src: url('assets/HighTide.otf')
font-family:'HighTideSans';
src: url('assets/HighTideSans.otf')
}
body {
padding: 0;
margin: 0;
}
canvas {
vertical-align: top;
z-index: -1
}
.title {
font-family:'HighTide';
font-size: 10vw;
margin: auto;
text-align: center;
z-index: 1;
}
.enter {
font-family:'HighTideSans';
font-size: 2vw;
text-align: center;
margin: auto;
z-index: 1;
}
And here is the html:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>LockeDesign</title>
<script src="libraries/p5.js" type="text/javascript"></script>
<script src="libraries/p5.dom.js" type="text/javascript"></script>

<link rel="stylesheet" href="style.css">
</head>
<body>
<div class=title> WELCOME </div>
<a href="main.html" class=enter> </a>
</body>
</html>
Any suggestions are appreciated, thank you!
EDIT
Using position: absolute; works partially, all I had to do was add left: 0;
right: 0; and bottom: 50%; to re-center the text. Resizing the window would cause scrollbars to appear, which was less than desirable, so I added overflow:hidden; to the body tag. Now this works exactly as intended, thanks all!
I would suggest WRAPPING all of the content you wish to display over the dynamic background in a single div
Example
<html>
<body>
<div id="BodyWrapper">
<h1> This is an HTML Page </h1>
</div><!-- End BodyWrapper -->
</body>
</html>
Then apply some Z positioning to the BodyWrapper with css
#BodyWrapper{position:absolute; top:0; left:0; width:100%; height:100%; z-index:5;}
If the above is still not enough then you may have to delay the
showing of the body content (make sure the dynamic background
completely loads first).
You can set the initial display styling of the wrapper to
#BodyWrapper{position:absolute; top:0; left:0; width:100%; height:100%; z-index:1; display:none;}
and onLoad... call this function
function show_PageBody()
{
setTimeout(function(){ update_Wrapper(); },1000);
function update_Wrapper()
{
document.getElementById('BodyWrapper').style.display='block';
document.getElementById('BodyWrapper').style.zIndex = 5;
}
}
You can add a css transition for the opacity of the BodyWrapper so that it fades onto the screen instead of just appearing.
This should work (has worked for me in the pass).
If not please let me know.

I'm struggling on my website with members selecting in Firefox/Chrome etc to disable popup boxes / javascript alerts.
I use alert boxes to confirm things like, for example, if someone wants to delete a message.
However, if they delete a few messages too fast one after the other then Firefox etc gives the option to block further javascript alerts. Then my members can no longer delete their messages.
I'm sure they can fix it client-side, but what can I do server-side to stop members being given the option to block javascript alerts?
Thanks
Matt
I'm not sure that default browser alerts/popups are a great way to go from a UX perspective. Browsers typically block them for a very good reason - ads.
You might be interested in a library called alertify.js (http://fabien-d.github.io/alertify.js/).
Creating alerts with this library is pretty simple, and browsers will not block them:
alertify.alert("Hello World");
Confirm dialogs like what you mentioned in your question are pretty simple too:
alertify.confirm("Are you sure you want to delete the message?", function (e) {
if (e) {
// user clicked "ok"
} else {
// user clicked "cancel"
}
});
I whipped this together quickly if you do not want a heavy footprint (Not really styled either). But you can put raw html into your confirm boxes with this code.
HTML
<div id="confirm">
<div class="message"></div>
<button onclick="$('#confirm').hide()[0].success();">Ok</button>
<button onclick="$('#confirm').hide()[0].failure();">Cancel</button>
</div>
JS
var $confirm = $("#confirm");
function confirm(msg, success, failure) {
$confirm.find(".message").html(msg);
$confirm.show();
$confirm[0].success = success;
$confirm[0].failure = failure;
}
CSS
#confirm {
display : none;
width : 100px;
height : 100px;
position : fixed;
border : 1px solid black;
top : 5px;
right : 5px;
}
http://jsfiddle.net/hVC5A/4/
you can use a custom confirm/alert/prompt box here is an example i have made just note the css animations was some experimenting i was doing you dont need to include these

FIDDLE - working with exception of dialog close
Trying to change the background color of a box when it is flipped (it would be much easier to show you what I mean: (http://iam.colum.edu/students/jordan.max/demo/demo.php). I am new to jQuery and did a tutorial, and very easily able to de-engineer the code and figure out what to do to make it do what I want. I did this with relative ease up until I tried to change the color of the background when the element is flipped. It's very odd, because when I use 'inspect element' and i click the mouse thing over the object it says I set the background in "element" but that is non-existent in my CSS. Not trying to be confusing (this probably did sound confusing which is why I gave the link), hopefully someone knows what my issue is.

I have 5 diffrent backgrounds which change from one to another when mouseover menu links like that:
3 different screenshots out of 5
I want that the web site works properly in all browsers, but I get very different results. In firefox, background image dissapears and reappears on each menu link, but only first time when I go over a link with a cursor, other times works fine. In chrome backgrounds disappear and reappear on every onmouseover. And in IE onmouseover doesn't work at all nor the menu.
So I'm asking you to help me fix this, both things, dissapearing and the menu in IE. I found out that this disappearing and reappearing happens because of slow image loading, but I have no idea how to repair my code to fix this.
I just wrote my code in jsFiddle and menu doesn't work in it as well. And I noticed that when I downscale windows into the size smaller than div, the whole thing starts to deform. I thought I already fixed it, but it seems that I don't know how to that as well. You can see my code here:

For blinking background images, and other images which you want to use from JS, you need to preload, or it will be blinking. How to preload an image? Click here
(It's blinking, because when the page was loaded, the image wasn't. So, that image which you want to use, isn't at the user. The browser download it, but until that time, theres no image what it can show for him/her. This is the reason.)
IE is blocking JS in default (like IE 10). You need to enable it. I've got a warning bubble an the bottom, which say, I've blocking everything... or something like that. You can't enable this from script. Only you can create a warning message for the user, which you remove if JS is enabled.
An extra thing, in jsFiddle it will work the page if you select the "no warp - in <head>" option from the second drop down list at top left. After that you need to click run at top.
There are 5 floated divs which heights are stretched to 100% of document height using Javascript. All 5 of them contain img element.

Javascript:

function colsHeight(){
var docHeight = $(document).height();
$("#wrapper div").height(docHeight);
};
$(document).ready(function(){

});
and CSS:

}
#wrapper img{

div.clear:after{

}
I've tried setting parent's div display: table and img display: table-cell, vertical-align: middle but no luck. Defining margin-top: 50% is acting anything but expected.
JSFIDDLE HERE!!!
Any help appreciated.
Thanks!
You could position them absolutely, then set top: 50% and margin-top: -63px. Of course, this only works if you know the height of the image (126px in your case). If the image sizes are dynamic, the easiest, but yucky way would be to set the margin-top on the images using js after they are loaded.
Anyway, the static method can be seen here: http://jsfiddle.net/3gqcS/2/
This feels a bit dirty, but you can set the div's line-height to div height + image height then overflow:hidden
<div id="static" style="height: 481px; line-height: 607px; overflow: hidden;">
since you using javascript and jQuery(can't live without him) you can do....
check this: http://jsfiddle.net/828pW/
here is the code:
function verticalAlignImage(img)
{
if(img.height)
{
$(img).css({
position:'absolute',
top: ($(img).parent().height() - img.height)/2
}).parent().css('position', 'relative');

setTimeout(function(){
verticalAlignImage(img);

}
}
Try setting the columns:
position:relative;
width:<width>;/* width must be set */
and the images as:
position:absolute;
top:0;
bottom:0;
margin:auto 0;
That should perfectly center them however then you need to set column width as the image with absolute positioning take up no space at all.
Also, instead of using java script just add:
html, body, #wrapper, #wrapper div{height:100%;}
instead.
