Let's say my html is setup like this:
<html>
<head>
</head>
<body>
<div id="site_banner">
<img>
</div>
<div id="site_content">
<div id="home_menu"></div>
<div id="home_content"></div>
</div>
</body>
</html>
All I want is my home_content to fill the rest of the view and then any additional content in home_content to be in overflow instead of overflow being in html, so that the site_banner and home_menu are always on screen as the user scrolls down and never disappears.
From what you're saying it sounds like you should be putting the "site banner" and "home menu" in a header tag which means it should be structured like this.
<html>
<head>
</head>
<body>
<header>
<div id="site_banner"><img></div>
<div id="home_menu"></div>
</header>
<div id="site_content">
<div id="home_content"></div>
</div>
</body>
here's a fiddle of it https://jsfiddle.net/Optiq/rx2qn1h9/
Here's the CSS I added to make it stay put
header{
position:fixed; /*this makes it stay in place*/
display:block;
top:0px; /*this bumps it to the very top of the page*/
width:100%;
height:80px;
background-color:red;
}
Using jQuery:
$("#site_content").height($(window).height()-$("#site_banner").height());
$("#home_content").css("overflow-y","auto").height($("#site_content").height()-$("#home_menu").height());
Here's a JSfiddle:

I was was wondering if I could make an alert and a picture appear then disappear here's my code
<!DOCTYPE html>
<html lang="en">
<head>
<title></title>
<meta charset="utf-8">
<style>
</style>
</head>
<body>
<center><h1>Are you human???</h1></center>
<button id="button">Yes</button>
<button onclick="no" id="no">No</button>
<script>
function no(){
alert("Really you are interesting")
}
There is no pictures in your code.
But if you mean - show alert popup window, you should add parentheses like so onclick = "no()"
You cannot customize alert window.
But if you want just show some picture after button click, you should add <img> with display: none to the page and onclick change it to display: block.
You can't put a picture in the alert box.You can achieve it by putting up an image in a div keeping the display:none for that and then show hide it like this
function no() {
alert("Really you are interesting")
$("#msg").fadeIn("slow").delay("100").fadeOut("slow");
}
div{
position:fixed;
background-color:rgba(0,0,0,0.8);
width:100%;
height:100%;
display:none;
}
<div id="msg">
<img src="https://www.w3.org/html/logo/downloads/HTML5_Logo_512.png"/>
</div>
<center>
<h1>Are you human???</h1>
</center>
<button id="button">Yes</button>
<button onclick="no()" id="no">No</button>

I have a website where ALL of my content pages open inside of an iframe.
One of the issue I am having, is when a visitor opens a 2nd page on my site, it opens at the same 'scroll position' as the previous page they were on.
I would like all of my pages to open at the top.
NOTE: I have spent days and hours searching on this site and other sites trying to find something that works. None of the solutions I have found have worked so far.
So... I decided to post my question and a very stripped down example of 3 pages to see if I can get some much needed help with this.
Any help or advice is appreciate.
Here is the 'index' (parent) page:
<!DOCTYPE html>
<html>
<head>
<style>
body{margin:0;}
.header{width:100%; height:60px; background-color:blue;}
.header a{vertical-align:middle; line-height:60px; font-family:Arial; font-size:12pt; color:#ffffff;}
#myiframe{width:100%; height:2000px;}
.footer{width:100%; height:60px; background-color:blue; margin-bottom:20px;}
.footer a{vertical-align:middle; line-height:60px; font-family:Arial; font-size:12pt; color:#ffffff;}
</style>
</head>
<body>
<div class="header"><a>This is the Header of the index (parent) page.</a></div>
<iframe id="myiframe" name="myiframe" src="1stPage.html"></iframe>
<div class="footer"><a>Footer</a></div>
</body>
</html>
Here is the 1st 'content' page (including the last failed scroll code):
<!DOCTYPE html>
<html>
<head>
<style>
body{margin:0;}
.text{font-family:Arial; font-size:12pt;}
.link{margin-top:1900px;}
</style>
<script>
$(document).ready(function(){
$('html, body').scrollTop(0);
$(window).on('load', function() {
setTimeout(function(){ $('html, body').scrollTop(0);}, 0);
});
});
</script>
</head>
<body>
<div class="text">This is the 1st page in iframe (..and this is 'page postition' "Top" or "0").</div>
<div class="text">Please scroll down to the link to 2nd page.</div>
<div class="link"><a class="text" href="2ndPage.html" target="myiframe">Click here to go to 2nd Page</a></div><br>
<div class="text">This is the 1st page in iframe (..and this is 'page postition' "Bottom" or "X").</div>
</body>
</html>
And finally... the 2nd 'content' page (also including the last failed scroll code):
<!DOCTYPE html>
<html>
<head>
<style>
body{margin:0;}
.text{font-family:Arial; font-size:12pt;}
.link{margin-top:1900px;}
</style>
<script>
$(document).ready(function(){
$('html, body').scrollTop(0);
$(window).on('load', function() {
setTimeout(function(){ $('html, body').scrollTop(0);}, 0);
});
});
</script>
</head>
<body>
<div class="text">This is the 2nd page in iframe (..and this is 'page postition' "Top" or "0").</div>
<div class="text">Please scroll down to the link to 2nd page.</div>
<div class="link"><a class="text" href="1stPage.html" target="myiframe">Click here to go back to the 1st Page</a></div><br>
<div class="text">This is the 2nd page in iframe (..and this is 'page postition' "Bottom" or "X").</div>
</body>
</html>
You can do it in the iFrame onload event, as this:
<iframe id="myiframe" name="myiframe" src="1stPage.html" onload="scroll(0,0);"></iframe>
I am struggling to change CSS based on user actions with some script. Currently I have each navBar button performing 5 functions onClick. 1 each to change the CSS of 5 different divs. Since I am newer to scripting, I wanted to make an example similar to what I am doing in order to refer back in the future as well as hopefully help out the next person to come along.
Can someone please help me with this short example? I have tried many various scripts and just end up destroying my spirits.
For this, I want to click an openButton in the navBar and have it change the width (essentially open) a corresponding div on the page.
<div id="navBar">
<a id="div1OpenButton" class="openButton" onClick="openDiv()">div1</a>
<a id="div2OpenButton" class="openButton" onClick="openDiv()">div2</a>
<a id="div3OpenButton" class="openButton" onClick="openDiv()">div3</a>
</div>
<div id="main">
<div id="div1"></div>
<div id="div2"></div>
<div id="div3"></div>
</div>
<style>
#div1 {width: 0px;}
#div2 {width: 0px;}
#div3 {width: 0px;}
</style>
Don's use onclick within your HTML - that is bad practice. You want a separation of concerns, with your JS in a separate file.
If you use jQuery (which a good library for a use-case like this), you can use its powerful selector to select all five elements at the same time. jQuery's selector is nice for beginners because it's identical to how you use selectors in CSS.
I also like to attach my JS to my HTML via IDs, not classes. This way, you know your JS has unique HTML targets to attach to.
Putting all of this together, use the jQuery selector to select all buttons, then use a .click() event to encapsulate your CSS manipulation in an anonymous function:
$(".openButton").click(function() {
$("#div1, #div2, #div3").css("width", "500px");
});
There are better ways to do it, but following the line of your code, you must pass a param to your openDiv function such as the ID of the element you want to show.
<a id="div1OpenButton" class="openButton" onClick="openDiv('div1')">div1</a>
Your onClick function must to hide all divs inside your "main" and show only the id you just passed by param.
If you need more help, paste your code please.
Try this
<html><head>
<script src=path/to/jquery.js></script>
</head><body>
<div id="navBar">
<!-- openDiv(1) with "1" is the div number -->
<a id="div1OpenButton" class="openButton" onClick="openDiv(1)">div1</a>
<a id="div2OpenButton" class="openButton" onClick="openDiv(2)">div2</a>
<a id="div3OpenButton" class="openButton" onClick="openDiv(3)">div3</a>
</div>
<div id="main">
<div id="div1">div1 opened</div>
<div id="div2">div2 opened</div>
<div id="div3">div3 opened</div>
</div>
<style>
div#main div {overflow:hidden;width:0px} //to hide div content while closed
</style>
<script>
function openDiv(n) {
$('#div'+n).width(400);} // set width to 400px
</script>
</body></html>
OR without the inline onClick()
<html><head>
<script src=path/to/jquery.js></script>
</head><body>
<div id="navBar">
<a id="div1" class="openButton" >div1</a>
<a id="div2" class="openButton" >div2</a>
<a id="div3" class="openButton" >div3</a>
</div>
<div id="main">
<div id="div1">div1 opened</div>
<div id="div2">div2 opened</div>
<div id="div3">div3 opened</div>
</div>
<style>
div#main div {overflow:hidden;width:0px} //to hide div content while closed
</style>
<script>
$('a.openButton').click(function() {
var itm = $(this).attr("id");
$("#main div#"+itm).width(400);} );// set width to 400px
</script>
</body></html>
Firstly, don't mix HTML, CSS and JavaScript in the same file. You should write your JavaScript code in a .js file, and your styles in an external stylesheet ;
Add handlers on events in your JavaScript code by using element.addEventListener() ;
Use data attributes on your buttons to link them with target divs.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1">
<title>My page</title>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
</head>
<body>
<div id="navBar">
<a class="openButton" data-target="div1">div1</a>
<a class="openButton" data-target="div2">div2</a>
<a class="openButton" data-target="div3">div3</a>
</div>
<div id="main">
<div id="div1" class="container hide"></div>
<div id="div2" class="container hide"></div>
<div id="div3" class="container hide"></div>
</div>
</body>
</html>
And in the script.js file:
document.addEventListener('DOMContentLoaded', function(event) {
var divs = document.querySelectorAll('.openButton');
for (var i = 0; i < divs.length; i++) {
divs[i].addEventListener('click', openDiv);
}
});
function openDiv(e) {
// Use e.target.dataset.target
// Add 'hide' class on all containers
var containers = document.querySelectorAll('.container');
for (var i = 0; i < containers.length; i++) {
containers[i].classList.add('hide');
}
// Remove 'hide' class on the container to display
document.getElementById(e.target.dataset.target).classList.remove('hide');
}
<a id="div1OpenButton" class="openButton" onClick="openDiv(this)">div1</a>
<script>
function openDiv(e){
document.getElementById(e.innerHTML).style.width= '20px'
}
</script>
i want to make the map'e height is auto with the device's screen...
but when i change the style.height to auto, 100%, screen.height, the map is disappear...
how to make the height is auto?
this is my code...
script.js
$('#home').live('pagecreate',function(){
document.getElementById('map_canvas').style.width=screen.width;
document.getElementById('map_canvas').style.height="20em";
});
in index.html i just called
<div id="home" data-role="page">
<div data-role="header">
*my header*
</div>
<div data-role="content">
<div id="map_canvas"></div>
</div>
</div>
if you use jquery you can do as below:
instead of this:
document.getElementById('map_canvas').style.width=screen.width;
document.getElementById('map_canvas').style.height="20em";
you can use:
$("#map_canvas").css({
'width':screen.width,
'height':"20em"
});
Please check this example:
I think your problem is related to css not to javascript.
The % height you want to set will be based on the parent height, so if the parent is empty, the 100% of 0 will be 0: check this
code example:
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<body>
<style>
#map_canvas{
background-color:#00F;
}
#cont{
background:#F00;
height:200px;
}
</style>
<button onClick="doit1()">Click me to put something in map_canvas</button>
<button onClick="doit()">Click me to make the height 100%</button>
<div id="home" data-role="page">
<div data-role="header">
*my header*
</div>
<div id="cont" data-role="content">
<div id="map_canvas"></div>
</div>
</div>
</body>
<script>
$('#home').live('pagecreate',function(){
$('#map_canvas').css('height','auto');
});
function doit(){
$('#map_canvas').css('height','100%');
}
function doit1(){
$('#map_canvas').html('a')
}
</script>
</html>
I want to make the last/third div to be filled the whole remaining space. I given the 100% height but there is scroll bar is coming, which i dont want to show. I there any CSS solution for same. if not possible from css then the jQuery/JS solution will be fine.
<html style="height:100%">
<head>
<style type="css">
html , body {
width:100%; height:100%;
padding:0px;
margin:0px;
}
</style>
</head>
<body style="height:100%;padding:0px;margin:0px;">
<div style="height:100%;width:100%">
<div style="height:100px;background-color:#ddd"> </div>
<div style="height:25px;background-color:#eee"> </div>
<div style="display:block;height:100%;background-color:#ccc"> </div>
</div>
</body>
</html>
In jQuery, you can try something like this:
$(function() {
$(window).resize(function() {
$('div:last').height($(window).height() - $('div:last').offset().top);
});
$(window).resize();
});
Whenever the window is resized, the last div's height is modified so that the div extends to the bottom of the page. Window's resize method is called on page load so that the div is resized immediately.
If you substract the top offset of the div from the height of the window, you are left with the maximum height available. If you have margins, borders of padding applied, you might have to adjust the value which is substracted, for example:
$('div:last').height($(window).height() - $('div:last').offset().top - 30);
Assuming you want the div 30px from the bottom of the window.
On modern browsers: set position: relative on the container div, position: absolute on the third div. Then you can position it to the top and bottom of the container the same time: top: 0px, bottom: 0px;
You could also use faux columns by adding a vertically repeating background image to the CSS making the columns appear toy the space - this gives the appear. You could add this image to the div that wraps the three columns or to the body tag.
If these columns a going to have content in them it's probably worth adding some as the columns will behave differently.
You can hide the overflow in the containing DIV:
<html>
<head>
<style>
*{margin:0;padding:0;}
html,body{height:100%;}
</style>
</head>
<body>
<div style="overflow:hidden;height:100%">
<div style="height:100px;background-color:#ddd"></div>
<div style="height:25px;background-color:#eee"></div>
<div style="height:100%;background-color:#ccc"> </div>
</div>
</body>
</html>
Note that content might dissapear when resizing the window using this technique.
You can use pure CSS height:100% (where 100% is the height of the visible area in the window) values in quirks mode by not using DOCTYPE at all or using IE-faulty HTML 4.0 DOCTYPE (without the .dtd url)
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<body style="margin:0; padding:0; overflow:hidden;">
<div style="height: 100%; background: red"></div>
</body>
</html>
You can ditch the <!DOCTYPE.. entirely, it still would have the same effect. overflow:hidden declaration in body style is to get rid of the empty scrollbar in IE. But remember - this is quirks mode which means that you are on unpredictable territory, CSS box model differs from browser to browser!
html style="height:100%">
<head>
<style type="css">
html , body {
width:100%;
height:100%;
padding:0px;
margin:0px;
}
</style>
</head>
<body style="height:100%;padding:0px;margin:0px;">
<div style="height:100%;">
<div style="height:100px;background-color:#ddd"> </div>
<div style="height:25px;background-color:#eee"> </div>
<div style="position:fixed;top:125px;height:100%;width:100%;background-color:#ccc"> </div>
</div>
</body>
</html>
Perhaps this could work?! But I don't know whats happens if there is to mutch text...
Simply don't worry about it if your goal is to have the colour fill the bottom.
Set the colour of the outer div, and let the third one resize its height however it wants as content goes in.
<html style="height:100%">
<head>
<style type="css">
html , body {
width:100%; height:100%;
padding:0px;
margin:0px;
}
</style>
</head>
<body style="height:100%;padding:0px;margin:0px;">
<div style="height:100%;width:100%;background-color:#ccc">
<div style="height:100px;background-color:#ddd"> </div>
<div style="height:25px;background-color:#eee"> </div>
<div style=""> </div>
</div>
</body>
</html>
The property 'height: 100%;' will instruct browsers to take the 100 per cent of the available screen space for that particular div, which means that your browser will check the browsing space size and return it to the CSS engine without checking whether there are any elements inside it.
The only workaround that I see to fit here is to use the solution provided by David to use 'position: absolute; bottom: 0;' for that div.
it a bit ugly, but it works..
<html style="height:100%">
<head>
<style type="css">
html , body {
width:100%;
height:100%;
padding:0px;
margin:0px;
}
</style>
</head>
<body style="height:100%;padding:0px;margin:0px;">
<div style="width:100%;height:100%;">
<div style="width:100%;height:100px;background-color:#ddd;"> </div>
<div style="width:100%;height:25px;background-color:#eee;"> </div>
<div style="width:100%;height:100%;background-color:#ccc;margin-bottom:-1000em;padding-bottom:1000em;"> </div>
</div>
</body>
</html>
Here's a litle jquery fix I have done:
<html>
<head>
<title>test</title>
<script src="jquery-1.3.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
var heightToFill = $("#parentDiv").height() - $("#firstDiv").height() - $("#secondDiv").height();
$("#thirdDiv").height(heightToFill);
});
</script>
</head>
<body style="height: 100%; padding: 0px; margin: 0px;">
<div id="parentDiv" style="height: 100%; width: 100%; position:absolute;">
<div id="firstDiv" style="height: 100px; background-color: #ddd">
</div>
<div id="secondDiv" style="height: 25px; background-color: #eee">
</div>
<div id="thirdDiv" style="background-color: #ccc;">
a</div>
</div>
</body>
</html>
$(window).resize(function(){
$('.elastic').each(function(i,n){
var ph = $(this).parent().height();
var pw = $(this).parent().width();
var sh = 0;
var s = $(this).siblings().each(function(i,n){
sh += $(this).height();
})
$(this).height(ph-sh);
sh = 0, ph = 0, s=0;
});
});
put the following on on your script tag or external javascript.
then change
when you resize the window... it will automatically fit its height to available space on the bottom. you could have as many divs as you like however you can only have one elastic inside that parent. couldnt be bothered to calculate multiple elastics :) hope it helps
$(document).ready(function() {
var heightToFill = $("#parentDiv").height() - $("#firstDiv").height() - $("#secondDiv").height();
$("#thirdDiv").height(heightToFill);
$(window).resize(function(){ var heightToFill = $("#parentDiv").height() - $("#firstDiv").height() - $("#secondDiv").height();
$("#thirdDiv").height(heightToFill);
});
This should be included in case the browser is resized....
window.onload = setHeight
window.onresize = setHeight
function setHeight() {
document.getElementById('app').style.height = window.innerHeight + "px"
}
