I'd like to create a bit of embeddable code that a user can drop into their website that will load some Javascript. If some conditions are met, I'd like to add a small header to the top of the site, pushing down the rest of the content. Is there a simple way to do this that'll work on most websites?
I understand how to load and execute the JS - I guess I'm just wondering what the HTML/CSS would look like on both my header, and what would need to be altered on the user's site.
Have you considered using a floating header on top of their websites as opposed to shifting their entire website down? I think that'd be significantly easier.
That way you could just smack a div anywhere like so:
<div id="header">Whatever content</div>
<style>
#header {
left: 0px;
top: 0px;
width: 100%;
height: 30px;
background-color: black;
z-index: 1;
overflow:hidden;
min-width:280px;
position: fixed;
}
</style>
Or you could remove the position: fixed if that's too annoying and just make sure your div is on top.

I've got a cordova app using jquery, jquery-mobile, iscroll and iscrollview
I'm not exactly committed to any of these tools.
I've got the jquery-mobile header/footer stuck to the top and bottom of the screen just fine.
I have a scrollable div between the header and footer. It will contain variable amounts of data. Sometimes the data will be less than the height of the div and sometimes it will be greater (hence the scrolling)
Here's the tricky part. I want to stick the bottom of the scrollable div to the top of the footer. When I add stuff to the div i want the most recently added closest to the top of the footer so the top of the scrollable div looks like its growing upwards towards the bottom of the header as data is added.
Once the top of the scrollable div is fille by its content then i want to be able to scroll it.
Has anyone been able to achieve something like this?
Here's a neat little trick for you.
<div class="header"></div>
<div class="content"></div>
<div class="footer"></div>
Now the CSS
div {
width: 100%;
}
.header {
position: absolute;
top: 0px;
left: 0px;
height: 50px;
}
.footer {
position: absolute;
bottom: 0px;
left: 0px;
height: 100px;
}
/* the magic */
.content {
position: absolute;
top: 50px; /* matches height of header */
bottom: 100px; /* matches height of footer */
left: 0px;
overflow: scroll;
}
The neat thing about forcing .content to have both a top and a bottom is that it stretches the div so that it's always the proper height. IF you specified height on it, it wouldn't work, but because the height is determined by the top/bottom property, it's dynamic. I think this gets you to where you want to be.
Here's a fiddle
Edit: Here's what it looks like with content
Edit 2 - forcing content to grow from the bottom.
I'm not sure this is a good idea, and I'm not sure I would ever seriously recommend doing things this way. However, using vertical-align it's possible to force content to grow from the bottom. I suspect that it would be better to just set a margin with javascript that shrunk as content grew, but... maybe not. With all that said, here's one way to do things with CSS.
This requires a little bit of restructuring of the content div.
<div class="content">
<span class="margin"></span>
<span class="inner"></span>
</div>
And a little bit more CSS
span.left-margin {
height: 98%;
width: 0px;
display: inline-block;
}
span.inner {
width: 99%;
background-color: white;
display: inline-block;
vertical-align: bottom;
}
It looks like this with a little content
It looks like this with a lot of content
If you want the scroll bar to stick to the bottom as content comes in, you'll need to do some javascript (easy to google it).
I'm not completely happy with doing things this way because if you set height 100% or width 100%, the content div gets a scrollbar automatically from the beginning. However... it looks pretty good and should work in most (if not all) browsers.
I've looked through a variety of other posts, and to no avail, I have yet to find the kind of solution I'm looking for. Many solutions involved people using CSS with methods like fixing the right and left (which wouldn't make it worth floating and a waste of brain power) or to word-wrap at a certain amount to the right (which also defeats the purpose of what I'm trying to do.
My problem exists like this:
I have 3 divs: wrapper, menu, and content. Wrapper is used to apply a background to 100% of the page, and create extra styling properties to be inherited by other CSS. Menu is for my menu script I coded in JQuery and it takes up 400px of space on the left hand of the screen and descends downwards at 100vh. I may change it to fixed, but it doesn't change the issue. Anyway, content is the rest of the page; let's say the other 80% of it. I have both menu and content floating left and it works just fine. However, until text wraps at the end of the screen, the div goes under (disappears in my case) the screen and no longer viewable.
My solution:
function simplyWidth(changed, menu1, wrapper){
var wrapperWidth = $(wrapper).width();
var menuWidth = $(menu1).width();
var newWidth = wrapperWidth - menuWidth;
$(changed).css("width", newWidth);
};
Does it work? Of course it works. The only problem is, it isn't dynamic at all! It resizes to the screen once, and you have to refresh the page just to get it to update again. Is there a way to take that JQuery/Javascript and make it so I can just update it every .1 of a second? Would that make the page lag? Or am I doing it wrong.
Also assume that my HTML is spot on, and it needs no corrections. The reason I won't disclose it is because there's too much there for me to post and to not confuse the living crap out of you people.
This is the basic layout of my page:
<div id="wrapper">
<div id="menu1"></div>
<div id="content"></div>
</div>
As for my wrapper CSS:
#wrapper {
width: 100%;
background-color:black;
margin: 0 auto;
top: 0px;
overflow:hidden;
height: 100vh;
background-image:url(Assets/background1.jpg);
}
Menu1 CSS:
#menu1 {
margin: 0 auto;
height: 100%;
width: 400px;
background-color:#191919;
color:white;
z-index: 400;
float: left;
}
Content CSS:
#content {
float:left;
color:white;
height: 100vh;
}
listen to resize event and call the same function when the window is resized:
$(window).resize(simplyWidth);
So I have a header bar for a page I made with a height of 150px. Under that area I want another DIV to fill the remaining space (width and height) all across the screen and to the bottom of the screen. I've tried setting height: 100% for the DIV, but that causes the screen to become scrollable and I only want it to fill the remainder of the page. NOTE: There is NO footer or anything under it.
Using jQuery/Javascript is acceptable, but CSS-only is prefered (if possible). If using jQuery, please explain the proper way to have it implemented into the page (I'm assuming $(function() {...}); under the <style> tag in the head.
I've tried searching for a result before, but nothing seems to work correctly.
tl;dr I basically made 3 options for you. click on the 'like this' in the below paragraph to see what they all look like without any text. Click on the A). B). and C). links in the paragraphs below that to see the difference between the three options. Check how each one scrolls differently, they are all different I promise. After you look at all three you can read how the one you want is implemented. (that is if you like any of them.) Hope you like it, no problem if you don't :)
I'll have a go at this, because it honestly depends on what you're going after there are multiple ways to look at it and it depends on your end goal. I will cover three possible scenarios: (which all look the same without text mind you, like this, but if you want to see what they look like with text click the letters. Make sure you scroll the page to see the difference between them.)
(Just as a side note I based A). and B). off how Twitter Bootstrap does it.)
A). You just want it to look like one div on top of the other (header div on top of main-content div) and display like that, but you still want the page to scroll if the 2nd div's text overflows. In this implementation when they scroll will move the header out of view, but if you don't want the header div to move out of view that leads me to
B). Same as the first header div on top of main-content div, but when they scroll the header div will still stay in place at the top instead of moving out of view.
and last of all,
C). You really do want the div to stretch to the bottom of the screen and never have the scroll bar for the whole page. This could be used in some cases, for instance, Spotify makes a nice music app with this kind of style so that you never scroll the whole page just panes in the page.
Ok so first here is the html code used to construct all three of them
<body>
<div class="header"></div>
<div class="main-content"></div>
</body>
And now to the fun part...
I will provide a Fiddle for the following examples, and with the css I will put the necessary code at the top and the unneccessary code at the bottom. (The html may have some unneccasary text so just ignore that. I just want you to see the page scrolls differently on the three.)
A).
no need to rephrase what it is so I'll just show you the code that is necessary.
First, here is A). without the text just so you can see what it looks like the others until the content gets too large.
Here is the fiddle with the text so you can see how it differs.
Here is the necessary css for A). (the background-color isn't completely necessary, but it is somewhat necessary to show the point.)
body {
padding-top: 150px;
background-color: #ddd;
}
.header {
position: absolute;
top: 0;
left: 0;
right: 0;
height: 150px;
background-color: #676767;
}
and now for...
B).
First, here is B). without the text just so you can see what it looks like the others until the content gets too large.
Here is the fiddle with the text so you can see how it differs.
Here is the necessary css for B).
body {
padding-top: 150px;
background-color: #ddd;
}
.header {
position: fixed;
top: 0;
left: 0;
right: 0;
height: 150px;
background-color: #676767;
}
As you can probably tell the only difference is the position: fixed on the .header, but look at the two examples to see the difference it makes.
and now last of all C).,
C).
First, here is C). without the text just so you can see what it looks like the others until the content gets too large.
Here is the fiddle with the text so you can see how it differs, and with I'll call option 1 where it has a scroll bar just for that area's overflowing content.
Here is the fiddle with the text so you can see how it differs, and with I'll call option 2 where it hides the overflowing content. (This is honestly bad practice and I wouldn't do it. So if I may suggest. I would go with option 1 of C).)
Here is the necessary css for C).
body {
padding-top: 150px;
}
.header {
position: fixed;
top: 0;
left: 0;
right: 0;
height: 150px;
background-color: #676767;
}
.main-content {
position: fixed;
top: 150px;
left: 0;
right: 0;
bottom: 0;
background-color: #ddd;
}
I won't explain it, but here is an article on positioning that will.
here is the only necessary css for option 1 is adding overflow-y: auto to .main-content, but if you want to go with option 2 which I don't suggest you can go with overflow-y: hidden on .main-content
Well that's all for my post which is probably too long for most people sorry if I bored you, but I'm just trying to help. Hope you figure out the layout you want. This is only a few examples of the layouts possible with good old css. If you don't get the layout you want from this or any other post feel free to send me a message by commenting below, and I'll be happy to answer it sometime. Hope this helped. If it didn't that's fine too. :)
You can try css3 flexbox.
http://jsfiddle.net/wL9aM/1/
.container {
display: -webkit-flex;
display: flex;
flex-direction: column;
height: 700px;
}
.header {
height: 200px;
background: red;
}
.main {
-webkit-flex: 1;
flex: 1;
background: blue;
}
try using script..
var window_h = $(window).height();
var header_h = $("header").height(); //This is what you said you had 150px
$(".filler_div").height(window_h - header_h);
You can also put that inside a function() so that you can add it also when you resize the browser, the filler space also adjusts...
function setfillerDivHeight(){
//the code above
}
$(document).ready(function(){
setFillerDivHeight(); //the initial setting of height
});
$(window).resize(function(){
setFillerDivHeight(); //reapply setting of height when window resizes
});
<div class="full-page-height-wrapper">
<header></header>
<main></main>
</div>
html,body {
height: 100%;
margin: 0;
}
header {
height: 150px;
}
.full-page-height-wrapper {
min-height: 100%;
position: relative;
}

I don't think you cannot acheive that in pure CSS.
So, there is two different solutions:
1) You can put the 150px div in the 100% div.
2) You can do it with jQuery:
If your top div is <div id="A"> and the second one is <div id="B">, you'll have:
var b = $("#B");
var height = $("body").height() - b.position().top;
b.css({ height: height });
Feel free to adapt the code if you have some margins.
Found a solution myself finally. Doing it this way makes the design more responsive since (if i choose to add something to the bottom), it will automatically resize the div's height.
.container {
display: table;
}
.row {
display: table-row;
}
.column {
display: table-column;
}
#fullDiv {
height: 100%;
}
I found two solution.
The one is that I have must set the div in the absolute position.
the div float over the screen.
another one is use table-row display.
If you use just CSS, you cant achieve your task by giving 100% height to div. Because what basically CSS is doing is giving 100% height to your DIV plus giving 150 px to above header. Consider giving height of DIV less than 100% or some static value such as 600px or 700px.
Alternate is having a class of DIV with min-height 100% and inside it putting your header and body.
I have searched everywhere and have yet to get a solution. Okay heres the deal, I have a one page website which has several div elements underneath each other, sort of acting like individual pages I guess. What I want to achieve is to disable the scrolling of the actual web page all together, yet keeping the scroll of the active div in play if it goes below the web browser. To get to each other section of the page is simple done by using anchor links on the header.
I'm not exactly sure what you're looking for, but I think you want a div to be scrollable, but not the actual document. You can do this by absolutely positioning the div on the screen with a fixed height and set the overflow to auto. I've done this using the following CSS code:
#scrollable {
position: absolute;
top: 10px;
right: 10px;
bottom: 10px;
left: 10px;
overflow: auto;
}
See an example: http://jsfiddle.net/rustyjeans/rgzBE/
Have you tried with
overflow-x:hidden;
turns out its quite simple.
CSS
body{
overflow:hidden;
}
#div_you_need_scrolling{
overflow:auto;
}
I'm developing a chrome extension, without going too much into it I need to inject some code into webpages and put an overlay over the full page. Thus far I have nearly achieved this butI just cannot seem to get the overlay over certain parts of some websites. These include videos from youtube, the searchbar on top of google search results, random parts of kongregate (the stars and monthly comp info).
Below is the css I'm currently using to achieve this, I have played around and looked for solutions at various places but no solutions seems to work.
.cssX9482Overlay
{
position: fixed;
width: 100%;
Height: 100%;
vertical-align: middle;
background: #000000;
opacity: 0.97;
filter: alpha(opacity=97);
text-align: center;
top: 0;
left: 0;
}
The strange css name is just so it doesn't clash with pages formatting. As you probably guessed this is being used to format a div
Remember this is a Chrome extension, therefore HTML5 and CSS3 solutions are valid.
<style type="text/css">
iframe, div {
position:absolute;
top:20px;
left:20px;
width:200px;
height:25px
}
iframe { z-index:1 }
div {
z-index:2;
background:#000;
border:solid 1px red;
color:#fff;
}
</style>
<applet code="myApp.class" width="700" height="700"></applet>
<iframe></iframe>
<div>EXAMPLE TEXT</div>
TAKEN FROM: http://www.bluestudios.co.uk/blog/?p=6
Also you had height capitalized
You might need a z-index in there; on a Google search results page for me, adding a z-index: 999; covers everything except the top navigation (Web, Images, Videos). This is because Google's CSS looks like:
#gbz, #gbg {
...
z-index: 1000;
}
Elements with a larger z-index are placed on top of others. Even while using this property, I've had problems in the placing content on top of Adobe Flash elements and Java applets.
