Exmaple:
http://jsfiddle.net/vjqjv/7/
I have an image inside of a container (see #slider-section in the jsFiddle) which has a fluid height and a fixed max-height.
I have set max-height and max-width on my image to 100% (see #slider-img).
The Problem: When the browser window gets beyond a certain width, the image ignores the max-width and max-height setting and just gets larger then its container.
You can see it if you open the jsFiddle and expand the width of the browser.
The goal is to get the image to never exceed the width and height of its container and keep its aspect ratio.
This could be achieved by giving the container (#slider-section) a fixed height. However this is not a possible solution for me since it needs to be a fluid height.
Does anyone have a solution?
Is this what you need ? http://jsfiddle.net/vjqjv/10/

Re media query in code
I have had to put all of the code here so you can see my question in context with this code for a basic website. The part of this code I'm referring to is the media query coded below as:
# media (max-width: 700px)
body { background-color: #fff; }
I've done some research on media queries as required and know that in this code that when the page is at width 700px or less it will become the color of #fff which I think is a white color. But what would be the purpose of putting the code here besides a teaching exercise? Is it so that it will fit a mobile phone if the web page where to be opened on such a device? I thought that instead of using a media query that the width of the webpage to fit a device like a mobile phone was established in the meta tags viewport description. Please bear in mind I'm a newbie and just starting to learn about coding about a month ago.

It looks like your code is missing a bracket for the media query. I believe it should look like this. When the window is less than 700px the background is white. When greater than 700px it's a gray. Try re-sizing the window to see what I mean.
#media (max-width: 700px) {
body {
background-color: #fff;
}
div {
width: auto;
margin: 0 auto;
border-radius: 0;
padding: 1em;
}
}
Snippet
body {
background-color: #f0f0f2;
margin: 0;
padding: 0;
font-family:"Open Sans", "Helvetica Neue", Helvetica, Arial, sansserif;
}
div {
width: 600px;

Look at following JSFiddle: http://jsfiddle.net/ep6mtoa7/ (Btw. there was a missing { after the Media Query that I inserted here)
#media (max-width: 700px) {
body {
background-color: #fff;
}
div {
width: auto;
margin: 0 auto;
border-radius: 0;
padding: 1em;
}
}
If you increase the width of the box, you will see a grey background and in the middle will be a Box with rounded edges. If you decrease the width of the box, you will see that the grey background disappers and the box disappears too, but the white Background stays. The real need is because the box has a height, so only the box part would be white and the rest (top and bottom area) would still be grey.
Look at following JSFiddle: http://jsfiddle.net/ep6mtoa7/1/ (I removed the background-color: #fff)
You will see that the bottom part is still grey. If you put in the background-color part it will be white.
To your other question: The media query looks for device width, so mostly devices have a smaller width than your PC would have. The meta-tag part says something like if the zoom should kick in or if it's even allowed.
So if you saying that your page should be 1024px wide, the phone would fit the page into a 1024px viewport and you don't have to zoom in/out as an user.
At this point I am not sure if it's smart to go so deep into it, maybe first learn the basics more and then go deeper. But I like the effort you putting in, also google and read read read read as much blogs and stackoverflow threads as you can, this is a must do and will improve you alot!
dompdf: top-margin after page break not working
I'm experimenting with Wordpress and (the recent version of) dompdf at the moment and ran into an annoying problem regarding the formating.
My Problem: The top-margin of the main content seems not to be considered on the second page generated, resulting in an overlapping with my logo. You can view the generated PDF under this link.
The relevant code from which the PDF is generated reads as follows (it is not perfect yet as i want to resolve the issue first):
function ppt_pdf_output() {
// post-ID of referring page needed
$post=get_post($_POST['postid']);
$output = '<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>'.$post->post_title.'</title>
<style>
body {
margin: 30px 0 0 0;
font-family:sans-serif;
text-align:left;
}
img {
margin: 15px 0;
}
#header,
#footer {
position: fixed;
left: 0;
right: 0;
color: #aaa;
font-size: 0.9em;
line-height:1.2em;
}
#header {
top: -30px;
/*border-bottom: 0.1pt solid #aaa;*/
}
#footer {
bottom: 0;
border-top: 0.1pt solid #aaa;
}
#header table,
#footer table {
width: 100%;
border-collapse: collapse;
border: none;
text-align: center;
color: #000;
font-size: 24px;
}
.entry-content {
margin: 100px auto 35px auto;
top: 0; left: 0; bottom: 0; right: 0;
background-color: #d1d977;
width:90%; height:auto;
}
.entry-title {
font-size: 18px;
text-align: center;
}
#header td,
#footer td {
padding: 0;
width: 50%;
}
#footer .page-number {
text-align: center;
}
.page-number:before {
content: "Seite " counter(page);
}
.gallery-item {
display:inline-block;
}
br[style] {
display:none;
}
.gallery + p {
clear:left;
}
</style>
</head>
<body><div id="header">
<table>
<tr>
<td>ANTRAG</td>
<td style="text-align: right;"><img src="path/to/logo.png" /></td>
</tr>
</table>
</div>
<div id="footer">
<div class="page-number"></div>
</div>';
$output .='
<!--<h1 class="entry-title">'. $post->post_title .'</h1>-->
<div class="entry-content">' .
apply_filters('the_content',$post->post_content) . '</div>';
$output .= '</body></html>';
return $output;
}
As you can see, the formatting on the first page is as it should be (or at least as I intended it to be), but after the page break the content area (for visualization reasons provided with a green background) just starts at the beginning of the page, regardless of which number I give the margin.
Has anybody an idea how to resolve this issue? I've been working on this for countless hours and just don't know what to do at this point.
Any help would be greatly appreciated.
Kind regards
Olli
UPDATE: Of course I found this solution only just. I will try this and see if I can get the issue resolved with this.
UPDATE2: Still no luck. I'm now stuck with the following code (the output can be found under the link provided earlier):
function ppt_pdf_output() {
// post-ID of referring page needed
$post=get_post($_POST['postid']);
$output = '<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>'.$post->post_title.'</title>
<style>
#page {
margin: 120px 50px 80px 50px;}
#header {
position: fixed;
top: -82px;
width: 100%;
height: 109px;
background: #aaa url("path/to/logo.png") no-repeat right;
}
#content {
width: 100%;
height: 85%;
background-color: #d1d977;
}
footer {
position: fixed;
bottom: -65px;
height: 30px;
background-color: #333399;
}
footer .page-number {
text-align: center;
}
.page-number:before {
content: "Seite " counter(page);
}
br[style] {
display:none;
}
</style>
</head>
<body><div id="header">
<h2>ANTRAG</h2>
</div>
<footer>
<div class="page-number"></div>
</footer>';
$output .='<h1>'. $post->post_title .'</h1>
<div id="content">' .
apply_filters('the_content',$post->post_content) . '</div>';
$output .= '</body></html>';
return $output;
}
It seems just so fragile. For example, as soon as I change the font-size of the h1 element, it gets overlapped by the logo. After the page break, it looks okay, but that just seems an coincidence - as soon as I change the font-size or the text, the text again gets overlapped. Will absolute positioning change anything or do you have any other tipps as how to resolve this anoying issue? Margins of any kind don't seem to work either.
You're on the right track. As you've seen, when an element is split across pages (as your content area is) some of the formatting information does not follow. This is by design.
The correct tact is to define the page margins so that they are large enough to hold your header/footer content and place the header/footer into that space. The content will then just fill the "body" of the document (i.e. the space inside the page margins). This is what you've attempted, but you haven't given enough space for the header. The header is positioned 82px inside the page margin but the height of the header is 109px. Because of this any content that has a small margin will still fall under the header.
Try this instead:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>"Kaffeefahrten" in Bornheim: hart durchgreifen, Senioren vor Betrügern schützen</title>
<style>
#page {
margin: 120px 50px 80px 50px;
}
#header {
position: fixed;
top: -115px;
width: 100%;
height: 109px;
background: #aaa url("path/to/logo.png") no-repeat right;
}
#content {
background-color: #d1d977;
}
footer {
position: fixed;
bottom: -65px;
height: 30px;
background-color: #333399;
}
footer .page-number {
text-align: center;
}
.page-number:before {
content: "Seite " counter(page);
}
br[style] {
display:none;
}
</style>
</head>
<body>
<div id="header">
<h2>ANTRAG</h2>
</div>
<footer>
<div class="page-number"></div>
</footer>
<h1>"Kaffeefahrten" in Bornheim: hart durchgreifen, Senioren vor Betrügern schützen</h1>
<div id="content">
...
</div>
</body>
</html>
Note that you also don't have to specify any height/width for the content element (unless you want to further constrict the space it uses).
With CSS3 you could go with your original styling and re-use the margins by applying the box-decoration-break property. However as of writing dompdf does not yet support this property.
Why my image doesn't respect its parent's (section) padding
I have a strange situation with an image and a section. You can download html, css and img1 from my github
The situation: I have a section tag which has padding:15px from all sides. In the section I have an img, floated left, then a p and a span with two buttons. The section has also a border and margin:35px
My problem: The image doesn't respect the section's bottom padding and goes through the sections bottom border.
I tried to put the img in a div inside the section, and also tried to give a height value for the section and 100% for the image's height but it didn't change anything
What is the best solution for this problem, so that the picture takes all the height of the section respecting the section's top, left and bottom paddings?
In the github, one step back, is a ppt-file TASKS.ppt. The third slide is what I try to achieve.
EDIT: Since code is requested, here it is:
HTML:

padding-bottom: 25px;
}
body header h1 {

}

padding: 15px;
margin: 35px 0px;
}
section img {
float: left;
}
section img:after {
clear: both;
}
image img1.png
This is a classic, search for clearfix. One possible solution is
section {
overflow: hidden;
}
See JSFiddle
Update:
There's an article about CSS float and clear at CSS-Tricks - All About Floats.
Essentially, you need clear, when
an element should stay below a floated element
and some clearfix, when
the parent of a floated element collapses and you want the parent wrap around/include the floated children
You can also look at Stackoverflow css-float tag wiki (an alias of css-clear) or clearfix
Background Image is Hiding Header and Navigation
I added a BG images to the body of a html document. after config of size and other properties, the head and list have just removed themselves. I looked at the webpage index file via web inspector, and they are physically there. just not displayed. and ideas why this behavior would happen? if you guys need to see the code just ask. thanks in advance... ~Ryozaki
A couple of HTML issues... Your <title> needs to go inside of your <head></head> tags. You can't put <div> tags between your <head></head> tags. You're missing a closing </head> tag Try this: Insert a <head> tag before your <title> tag. Then change your <head> tag after </title> to </head>
You need to review your positioning rules
If you have an element positioned as absolute it will overlay any elements below it, unless you position the elements below to absolute as well or position them to relative with a z-index greater than 0.
But for your particular case you don't need to add absolute positioning to your image, just leave it as static and it solves your problems.
here is the your css code revised and works (per as your Fiddle):
#font-face {
font-family: 'FlexDisplay-Thin';
src: url('mywebsite/fonts/FlexDisplay-Thin');
src: local('?'), url('FlexDisplay-Thin') format('ot'), url("FlexDisplay-Thin") format('truetype'), url(FlexDisplay-Thin) format('avg');
}
h1
{
font-family: 'FlexDisplay-Thin', arial, sans-serif;
}
#bg {
position: static;
top: -50%;
left: -50%;
width: 200%;
height: 200%;
}
#bg img {
position: static;
margin: auto;
min-width: 50%
min-height: 50%;
z-index:0
}
#navigation{
width: 550px;
height: 35px;
font-size; 16px;
font-family: 'FlexDisplay-Thin', arial,sans-serif;
text-align; center;
}
Z-index broken in IE8?
This code works in every other browser I've tried, except IE8.
IE8 appears to ignore the z-index - and the pop-up becomes a pop-under.
It's in the right place, just renders underneath the thumbnail.
Anyone?
Thanks!
HTML:
<a class="thumbnail" href="#thumb">
<img src="comic_a3_thumb.jpg" height="300" width="212" border="0"
style="float:right; margin-top:10px;margin-bottom:10px;"
alt="description" />
<span>
<img src="/images/comic_a3_popup.jpg" />
</span>
</a>
CSS:
.thumbnail{
position: relative;
z-index: 0;
}
.thumbnail:hover{
background-color: transparent;
z-index: 50;
}
.thumbnail span{ /*CSS for enlarged image*/
position: absolute;
background-color: lightyellow;
padding: 5px;
left: 0px;
border: 1px dashed gray;
visibility: hidden;
color: black;
text-decoration: none;
}
.thumbnail span img{ /*CSS for enlarged image*/
border-width: 0;
padding: 2px;
}
.thumbnail:hover span{ /*CSS for enlarged image on hover*/
visibility: visible;
top: -140px; /*position where enlarged image should offset horizontally */
left: -500px;
}
The simple answer is to add a z-index value that is greater than the .thumbnail:hover value to the hover state of the span.
.thumbnail:hover span{ /*CSS for enlarged image on hover*/
visibility: visible;
top: -140px; /*position where enlarged image should offset horizontally */
left: -500px;
z-index: 51;
}
Put these lines in your page head
<!--[if IE]>
<style>
#your_faulty_div{
background-color:#000; /*any color it doesn't matter*/
filter: alpha(opacity=0);
}
</style>
<![endif]-->
your_faulty_div is the div which is misbehaving due to IE z-index bug.
Works smooth , i use it in all of my projects where i have positioned elements overlaping.
If I understand you correctly, you want the span to show above the element marked as the thumbnail. You have not specified the z-index for the span element. Here is a working example:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-type" content="text/html; charset=UTF-8" />
<title>Pop-up Test</title>
<style type="text/css">
#vbox {
border: 1px solid black;
height: 200px;
position: relative;
width: 200px;
z-index: 0;
}
#vbox:hover #hbox {
display: block;
}
#hbox {
border: 1px solid blue;
display: none;
height: 200px;
left: 50px;
position: relative;
top: 50px;
width: 200px;
z-index: 1;
}
</style>
</head>
<body>
<div id="vbox">
<p>Hover over this box to show a hidden "pop-up".</p>
<p id="hbox">This box is a pop-up.</p>
</div>
</body>
</html>
The way to fix this issue is by adding a class to the thumbnail image like this:
.thumbnail:hover img.thumb {z-index:-50; position:relative;}
