You know, the 8 small iframes that show your most visited websites. How do they get the snapshots of the websites? How do they decide which websites to use? Just how do they work.
Edit: So that I can do something similar.
Edit 2: Is this not programming? I'm asking how to code an iframe that takes a snapshot of a websites.

By using an internal method that shows the picture (in this particular case; chrome-search://thumb/53/22) ? Did you take a look at the source?
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="common.css">
<link rel="stylesheet" href="thumbnail.css">
<script src="util.js"></script>
<script src="thumbnail.js"></script>
</head>
<body dir="ltr">
<a href="http://www.reddit.com/" ping="/log.html?pos=1" title="reddit: the front page of the internet" target="_top" tabindex="-1" style="color: rgb(119, 119, 119); font-size: 11px; font-family: arial, sans-serif;">
<span class="shadow"></span>
<!-- RIGHT HERE! -->
<img src="chrome-search://thumb/53/22">
</a>
</body>
</html>
Have a look at chrome-search://most-visited/thumbnail.js:
function createThumbnail(src) {...} // creates the thumbnails
you can try to remove the contents of
function showDomainElement() {}
if you don't want to see those in new tab page. I haven't tried this.

These snapshots are generated by internal layout engine. But, you can do it with some classes, like html2image, DOMPDF, etc.

What is the most beginner way to put some little changes into an HTML page?
For example, we need to choose between "./textC.js" and "./imgC.js" files, both having function countCows() {} of different algorithms.
I've spent lots of time browsing through "changing script src dynamically" articles, but location.reload() reloads the whole page (or a <div>, I haven't found the pattern yet), some things don't work at all, some answers use complicated high software technologies I have never seen before.
This be the template html page:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Template page</title>
<link id="sizescheme" rel="stylesheet" type="text/css" href="./texty.css" media="screen"/>
</head>
<body class="custombackground">
<div id="commonblock">
<button id="coucow" onclick="countCows()">Count the cows</button>
<div id="countResult"></div>
</div>
<div id="textOnly">
Something that has nothing to do with images
</div>
<script id="counter" src="./textC.js"></script>
</body>
</html>
The caller HTML page has something like this:
<div id="initial-things" >
<button id="txb" onclick="setType("t")"> Text </button><br />
<button id="imb" onclick="setType("i")"> Image </button>
</div>
And could have done this if it were the same page as the template (but scripts do not load dynamically, see the first paragraph):
<script>
function setType(param) {
if (param == "i") {
document.getElementById("sizescheme").href = "./imgy.css";
document.getElementById("counter").href = "./imgC.js";
document.getElementById("textOnly").style.visibility = "collapse";
}
if (param == "t") {
document.getElementById("sizescheme").href = "./texty.css";
document.getElementById("counter").href = "./textC.js";
}
}
</script>
So, how does one create a page from a template?

Please I'm trying to knockoff a loading bar on my site, I have searched through the files, still can't find it. I also tried inspecting using google chrome, but I couldn't target the loader. Kindly help out
Click here for to visit website.
<div class="pace pace-inactive">
<div class="pace-progress" style="width: 100%;" data-progress-text="100%" data-progress="99">
<div class="pace-progress-inner"></div>
</div>
<div class="pace-activity"></div>
</div>
Remove this html construct. There also should be a javascript/css which triggers the loading bar. You can remove that too.
It's inside your head:
<script src="assets/plugins/pace/pace.min.js"></script>
<link href="assets/plugins/pace/pace.css" rel="stylesheet">
just go the HTML of your page. there from the top, search for <body> tag. Just below it you'll find this :
<div class="pace pace-inactive"><div class="pace-progress" data-progress-text="100%" data-progress="99" style="width: 100%;">
<div class="pace-progress-inner"></div>
</div>
<div class="pace-activity"></div></div>
Remove all these lines and you'll be fine
and remove these two lines in your <head> tag
<link href="assets/plugins/pace/pace.css" rel="stylesheet">
<script src="assets/plugins/pace/pace.min.js"></script>
Remove Pace library/plugin from your index.html in head section
& from assets folder inside your application.
<link href="assets/plugins/pace/pace.css" rel="stylesheet">
<script src="assets/plugins/pace/pace.min.js"></script>

What has the best cross-browser support, JQuery dialogs or HTML5 modal dialogs? [closed]

I am trying to create an online app that needs to have multiple items of content open at one time. I have looked at JQuery dialogs and also HTML5 modal dialogs. Which of these should I choose to get the best cross-browser support? Is there a different implementation that would work better?
Sounds like maybe jQuery UI's Dialogs are what you're looking for? All you do is set aside some HTML in a container (such as a Div) and then render the dialog box.
Link: https://jqueryui.com/dialog/
To "create" the dialog, you'll just need to create a dialog from the container whenever you need it to be visible. Such as:
<script type="text/javascript">
$('#myPopup').dialog();
</script>
That page has an example of how to get started. For more detail with what you can do with them (such as adding buttons), check out the full API page:
Link: http://api.jqueryui.com/dialog/
Even better - you can also use custom themes or a variety of premade themes for jQuery UI. Check out Themeroller (http://jqueryui.com/themeroller/) to get yourself started.
Finally, you'll need to have both jQuery (https://jquery.com) and jQuery UI (https://jqueryui.com/) included in both of your projects for this to work. I'd recommend reading over the basic jQuery/jQuery UI tutorials if you are new to them.
Edit:
Here is an example on jsFiddle as well as an example of what a page would look like.
Fiddle: http://jsfiddle.net/uLGRA/
Code:
<html lang="en">
<head>
<title>Test</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.1.0.js"></script>
<script type="text/javascript" src="http://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.4/themes/humanity/jquery-ui.css">
<script type="text/javascript">
// when the document has loaded..
$(document).ready(function() {
// turn this ID into a dialog
$('#popupTest').dialog();
// also, turn the input type="button" into a jQuery UI Button
// for consistency
$('#btnRandom').button();
});
</script>
</head>
<body>
<div id="popupTest" title="Stackoverflow Example">
<p>Hello, world.</p>
<p>Care for a cup of tea?</p>
<input type="text" value="" placeholder="sample input form">
<input id="btnRandom" type="button" value="this button does nothing... yet">

I have a html page with a button whos onclick calls a javascript function...but I have been getting a function not defined error for two days! Can someone help?

<div data-role="dialog">
<div data-role="content" id = "test" data-theme="c">
$confirm
Cancel
</div>
</div>
</body>
</html>
This might be handy:
http://jquerymobile.com/demos/1.2.0/docs/pages/page-scripting.html
You need to stick your scripts within the page element:
<div data-role="page">
<script>
function doSomething(){
alert('this is a test');
}
</script>
<!-- the rest of your stuff -->
</div>
In fact i have passed personally with this error even with valide HTML all what you need to do is move all of your functions to the head element.
Here is a fiddle:

To demonstate what i have said in the framework & change the NoWrapToHead to onload
