How to get rid of white space around an <embed> element? - html

SUMMARY: an embed with 100% width and height pushes its parents size to be 100% width and height of the grandparent. How do I get the embed element to collapse all the white space around it so that it fits the width and height of its parent perfectly?
I have a page with an image, which upon being clicked gets replaced by an embed element that plays a quicktime movie.
The problem is that the embedded movie has a large amount of white space around it.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head><title></title></head>
<body>
<div style="border:1px solid #000;">
<embed id="iframeMovie" height="100%" width="100%" controller="true" target="myself" href="" src="http://images.apple.com/quicktime/troubleshooting/mov/qt_installed.mov" type="video/quicktime"></embed>
</div>
</body>
</html>
The video is of unknown size so how do I get rid of this whitespace while leaving height and width at 100%?
EDIT: Though it doesn't show, I am actually clearing the padding and margins. The white space still remains.
EDIT 2: The white space in question is between the movie and the black border, not the black border and the browser.

Are you clearing the default browser margin and padding? Otherwise, you need to do that.
Most people use CSS reset styles to normalize margin and padding across browsers. A good one to use is Eric Meyer's: CSS Reset
EDIT: To remove the space underneath the embed, set display: block on the embed. See: http://media.nodnod.net/embed.html

WOOHOO, I've searched a very long time for this answer and I finally found it!
You'll have to put the embed element in an object element which is in an iframe or a frame:
The iframe page
<html>
<body>
<iframe src="sample.html" height="100%" width="100%">
</iframe>
</body>
</html>
the iframe source
<html>
<body>
<object height="100%" width="100%">
<embed src="sample.mov" height="100%" width="100%"/>
</object>
</body>
</html>
Make sure that the height and width value in the iframe, object and embed element the same is.

I am not familiar with embed elements, but it seems to me that when you set the width to 100%, you set it to the width of the parent element, which is a div in this case and a div occupies the whole available width as it is a block element.
So you can either float the surrounding div or display it inline to have its size adjust to the contents instead of the available space around it.

Try setting float: left on both the div and the embedded element just like this. That will remove the extra white space.
<div style="border:1px solid #000; float: left; width: 100%; height: 100%;">
<embed id="iframeMovie" height="100%" width="100%" style="float: left" controller="true" target="myself" href="" src="http://images.apple.com/quicktime/troubleshooting/mov/qt_installed.mov" type="video/quicktime"></embed>
</div>

Hmm...
It's an ugly hack, but you could use a table:
<table width="100%" height="100%">
<tr>
<td align="center" valign="middle"><embed /></td>
</tr>
</table>

Have you used a DOM inspector to verify the whitespace isn't part of the embed?
Also, you can put it in a panel/div/etc and mess with the css:
position: relative; top: -10px; left: -10px; overflow: hidden;

it turns out that theres no way of doing this other than making the movie scale to the size of the parent by using scale="aspect".
While not the perfect solution, it will have to do for now.

Embed an html web-page inside another one and scroll it using the parent scollbar

I would like to have the contents of an html webpage displayed in another (parent) html webpage, stretch the embedded webpage to the width of the parent and also remove the scroll bar of the embedded webpage while being able to scroll down the contents of the embedded webpage using the the scroll bar of the main page as the height of the embedded contents are too long to fit. I tried using code from answers to similar problems including this:
<iframe style='overflow:hidden; width:100%; height:100%' scrolling = "no" src="annotated list of courses.html" frameborder="0" width="100%" height="100%"> </iframe>
but I cannot achieve the desired outcome. I would like is to be able to scroll the contents of the embedded webpage using the scrollbar of the parent page. It is possible (with no need to copy code form the embedded HTML to the parent one instead) and how? Thanks.
I solved the problem by specifying a specific height for the embedded webpage which is greater than or equal to the height of the webpage like this:
<div id="content" class="content content-full" style="margin-top: -40px;">
<iframe style='overflow-y:hidden; width:100%; height:17560px' src="annotated list of courses.html" frameborder="0" width="100%" height="17560px" type="text/html"> </iframe>
</div>
I hope this can solve the problem also for others and any better or different slolution is also appreciated.
ps: You have to specify a height that is at least equal to the height of the contents of the embedded webpage or element for the scrollbar to disappear.
I've solved it by using two DIVs, one inside the other.
<div style="overflow-y: hidden; border: 2px solid black; width: 300px; height: 300px; position:absolute; left: 100px; top: 100px">
<div style="margin-top: -100px; width: 300px; height: 400px">
<iframe scrolling="no" style='pointer-events: none; width:100%; height: 100%' src="https://earth.nullschool.net/#current/wind/surface/level/orthographic=-325.19,32.21,3000/loc=35.073,31.923" frameborder="0" type="text/html"></iframe>
</div>
</div>
I've disabled The scrollbars by setting scrolling="no"
I've diasbled user clicks by setting style='pointer-events: none;'
Here is a working sample - https://jsfiddle.net/q46L1ynv/

height="100%" works with <object> but not with <img>, difference HTML vs CSS width/height property?

I've got two codes and I don't know why the use of height=100% works only on image? in other cases it does nothing and the content choose the minimum height
the object ignore it but not the image.
<section id="corps">
<object data="images/test.pdf" type="application/pdf" width="100%" height="100%">
</object>
<img src="images/test.png" width="90%" height="90%">
</section>
And plus, Why width and height property works in html without style = "..." but others like min-height needs it. Is it just because html support these?
Thanks!
<style>
#corps{ height: Xpx} //replace X with the value that suits you
#corps object{height: 100%} //Now you'll get the 100% height
</style>
Alternatively, if you use position: absolute then height: 100% will work just fine.
About why <img src="images/test.png" width="90%" height="90%"> works, because height and width are HTML5 properties for images.
You can achieve the same thing by using <img src="images/test.png" style="width: 90%; height: 90%;">, Now this is CSS.

How to center iframe horizontally when there's a vertical scroll bar?

I have a top navigator, and an iframe below the navigator which load the content.
The layout is kind of like
<body>
<div style="text-align:middle">
<div id="nav"></div>
<iframe></iframe>
</div>
</body>
The navigator is set to fixed width to match the width of iframe content which is not full screen width. So that the navigator and the iframe are aligned at both sides.
But when iframe's height grows beyond the screen, the vertical scroll bar for the iframe shows up and the the iframe becomes a little left(no longer in the absolute horizontal position) and not aligned with the top navigator.
How could I make the iframe always showing at the center even with a vertical bar?
I think this should be a common issue but haven't searched out a similar question here...
Edit 1:
Attach a full sample here to illustrate this question.Here index is the main page, iframe2.html is a frame without vertical bar and iframe.html is the one with a bar. The blue block(iframe) is not aligned with the other two:
index.html:
<html>
<head></head>
<style type="text/css">
iframe {
width : 100%;
padding : 0;
margin: 0 auto;
display : block;
}
</style>
<body>
<div style="text-align:center;margin:0 auto;overflow:hidden">
<div style="background-color:red;width:900px;margin:0 auto;padding:8px 0 8px 0">
<span>test</span>
</div>
<iframe frameborder="0" scrolling="auto" src="iframe2.html" style="height:200px;"></iframe>
<iframe frameborder="0" scrolling="auto" src="iframe.html" style="height:100%;"></iframe>
</div>
</body>
</html>
iframe2.html
<html>
<head></head>
<body style="padding:0px;margin:0px;">
<div style="width:900px;height:190px;background-color:green;margin:0 auto"></div>
</body>
</html>
iframe.html
<html>
<head></head>
<body style="padding:0px;margin:0px;overflow-y:scroll">
<div style="width:900px;height:2000px;background-color:blue;margin:0 auto"></div>
</body>
</html>
Result:
You can center the iframe using css,
iframe {
margin: 0 auto;
display: block;
}
See the example: https://jsfiddle.net/bnby6umd/
After my comment (as this seemed to help you with the edits you have made):
Perhaps always force scrollbar even when it is not needed, and then align the navbar to that? body { overflow-y: scroll; }
and further to your reply, I would suggest the simplest way to keep the elements aligned would be to ensure they are the same width. As you are now forcing the scrollbar permanently, perhaps the easiest way to do this would be to add to the width of the first element, or remove from the width of the second, to account for the width of the scrollbar.
Although this would be very browser dependant as each browser may use a slightly different width scrollbar, as per this article, I suggest altering whichever width by 17 pixels, and see if that achieves the effect you are after.
UPDATE
Apologies, I misunderstood what you were after. The reason you are experiencing this issue is because you are getting confused between styling the iframe element and the content within the document it is displaying.
By setting the <div> within the 'iframe.html' files to a width of 900px, you are only styling the content being displayed. The 'outer' iframe element is being styled to 100% width, and so will span the full width of the window. Because of this, the centered content will be offset by the horizontal scrollbar, giving the appearance of not being aligned - however the actual iframe is not moving at all.
It is only possible to align the edges of two elements, regardless of their position, is for them to have the same width (obviously, as otherwise the edges could never line up). To do this, style the <iframe> to be of the correct width - what you do with the content behind that is then unimportant. This way, the width of the scrollbar will then be taken into account automatically, and the total width adjusted accordingly.
Basically, in the styling for the iframe, change width: 100%; to width: 900px;.
Here's a Fiddle.
I've tried to create a diagram to help explain:
On the left the content is offset by the scrollbar, whereas on the right, the element is styled and centered, not the content, and so the scrollbar just overlaps the content.

How to reposition content in no scroll iframe?

I have an iframe for a google chart which has too much spacing around it. I want to embed this in my page but crop it to get rid of the surrounding space.
I was trying to do this by setting the iframe with smaller height and width attributes but I cannot work out how to reposition the content within the iframe to center it.
Here is the iframe for the chart:
<iframe width="550" height="170" seamless frameborder="0" scrolling="no" src="https://docs.google.com/spreadsheets/d/1r56MJc7DVUVSkQ-cYdonqdSGXh5x8nRum4dIGMN89j0/pubchart?oid=1407844401&format=interactive" onload="window.frames['itunes'].scrollTo(250,250)">></iframe>
How do you reposition the content of an iframe in this way or is there a better solution?
Thanks
You should wrap the iframe in a div or something and position the iframe.
here the code:
<div class="wrapper">
<iframe></iframe>
</div>
and this is the css
.wrapper{overflow:hidden;}
.wrapper iframe{position:relative; left:-40px; top:-30px;}

<div> with image has a bigger height than expected

Here is an HTML code to reproduce the problem:
<!DOCTYPE html>
<html>
<body>
<div style="width:800px; margin:0 auto;">
<img src="logo.gif" width="100" height="40" />
</div>
</body>
</html>
When it is rendered in a desktop browser, the height of the only <div> becomes 45 pixels but not 40 as I expect (tested this in IE11 and Opera Next v20). logo.gif is 100x40, and the situation remains the same even if I apply zero border through CSS to the <img> tag (border, border-width, etc).
Why does it happen and how to fix it?
I believe it is not a bug as it is rendered the same way in all major browsers. The problem is fixed if we set just the display:block style. Without this, the image is rendered as an inline element, and its bottom border is aligned to the so called text baseline.
Let's change our code to demonstrate this:
<!DOCTYPE html>
<html>
<body style="background-color: #FFFF99;">
<div style="width:800px; margin:0 auto; background-color: #00CCFF;">
<img src="logo.gif" width="100" height="40" style="border: 3px solid black;" />
Some text yyy qqq
</div>
</body>
</html>
The result is the following:
As you can see, the extra space is needed to render the text without clipping!
I found a confirmation of that in the well-known book by Eric Meyer CSS: The Definitive Guide - in the section dedicated to alignment, when it describes the {vertical-align: baseline} attribute for the <img> tag. Here is the corresponding excerpt:
This alignment rule is important because it causes some web browsers always to put a replaced element's bottom edge on the baseline, even if there is no other text in the line. For example, let's say you have an image in a table cell all by itself. The image may actually be on a baseline, but in some browsers, the space below the baseline causes a gap to appear beneath the image. Other browsers will "shrink-wrap" the image with the table cell and no gap will appear. The gap behavior is correct, according to the CSS Working Group, despite its lack of appeal to most authors.
Same issue in FireFox and IE and Chrome.
You can fix this with a hack and add a Height:40px; to your div (I had to use an image to with the same width/height as your logo so don't be surprised that I have a different picture)
<div style="width:800px; margin:0 auto;border:solid;height:40px;">
<img src="http://a2.mzstatic.com/us/r30/Video/16/96/5f/mzi.rxlappss.100x100-75.jpg" width="100" height="40" />
</div>
Or, add some CSS to your image tag and keep the original code as is (will affect all images which may not be desirable)
img {padding:none;margin:none;display:block;}
http://jsfiddle.net/h6wrA/
Or, you can do this for only certain images with http://jsfiddle.net/h6wrA/2/
The only way I found to fix this problem correctly without height hacks, etc. is to set the container to line-height:0; (see demo example below).
.image { background:red; }
.image-fix { line-height:0; }
Image without Fix:
<div class="image">
<img src="http://via.placeholder.com/100x100" alt="">
</div>
<br>
Image with Fix:
<div class="image image-fix">
<img src="http://via.placeholder.com/100x100" alt="">
</div>
This is not a issue , you just need to write a correct CSS. Try
height:40px;display:block; for div tag and keep margin:0,padding:0
Thats all...
