Iframe Loading image and IE - html

I'm loading an Iframe from an External server of mine onto my webpage, and I wanted a loading image, because sometimes it take a good 10 seconds to load. All is well in Chrome but in IE nothing.
<center>
<div style="background: #ffffff url(http://mentalized.net/activity-indicators/indicators/simon-claret/progress_bar.gif) no-repeat 50% 5%;">
<iframe src="http://x.x.x.x/panel.php" allowTransparency="true" width="100%" height="450px" scrolling="no"></iframe>
</div>
</center>
My other question is, is there a better way of doing this? I can't use ajax because it's an external server, but is there a better way of doing a loading image with an iFrame? Thanks!

Try putting the style with the background image information on the iframe itself, rather than the separate div.
<iframe src="http://x.x.x.x/panel.php" allowTransparency="true" width="100%" height="450px" scrolling="no" style="background: #ffffff url(http://mentalized.net/activity-indicators/indicators/simon-claret/progress_bar.gif) no-repeat 50% 5%;"></iframe>

How can I make an iFrame next to another iFrame?

Currently the way the code works is that it places the iFrame on the bottom on the bottom. I want the last two iFrames to be next to each other so that one can hold, lets say a menu and the other can hold another web page. They would need to be adjacent to each other. That is side by side (no pun intended)
Someone suggested float : left. I tried this and it did float left but it floated the iFrame above it one to the left and not the current iFrame.
Code:
<!DOCTYPE html>
<html>
<body>
<iframe src="http://www.w3schools.com" width="600" height="200">
<p>Your browser does not support iframes.</p>
</iframe>
<iframe src="http://www.w3schools.com" width="200" height="500">
<p>Your browser does not support iframes.</p>
</iframe>
//I want this right next to the second iframe that is 400 width
//which would fill the rest of the screen
<iframe src="http://www.w3schools.com" width="400" height="500">
<p>Your browser does not support iframes.</p>
</iframe>
</body>
</html>
New Code:
<!DOCTYPE html>
<html>
<body>
<iframe src="http://www.w3schools.com" width="600" height="200">
<p>Your browser does not support iframes.</p>
</iframe>
<iframe src="http://www.w3schools.com" width="200" height="500">

</iframe>
//I want this right next to the second iframe that is 400 width
//which would fill the rest of the screen
<iframe src="http://www.w3schools.com" width="400" height="500" float : right>
<p>Your browser does not support iframes.</p>
</iframe>
</body>
</html>
easily done, you just need to set the display to inline-block for those two iframes.
iframe:nth-child(2),iframe:nth-child(3){
display:inline-block;
}
here's an example.
iframes are somewhat frowned upon. You might like to consider using divs with ajax instead, utilizing the jquery $.load function to load whatever you like into them. You can read up on that here.
Hope that helps...
Here is my attempt... The width of the window has to be more than 600px for the last 2 iframe to be beside each other. I used a div with clear:both; to make sure the last 2 iframe are under the first iframe
CSS:
body{
margin:0;
padding:0;
width:100%;
}
HTML:
<body>
<iframe src="http://www.w3schools.com" width="600" height="200" style="float:left;"></iframe>
<div style="clear:both;"></div>
<iframe id="test" src="http://www.w3schools.com" width="200" height="500" style="float:left"></iframe>
<iframe id="test1" src="http://www.w3schools.com" width="400" height="500" style="float:left"></iframe>
</body>
DEMO
You can set the two lower iframes to be side-by-side by giving them the display: inline-block style, as lukeocom mentioned above.
However, you should also then give them box-sizing: border-box and wrap them in a div with style display: table so that their width includes the size of the border, or else they won't line up well with the top iframe, as in lukeocom's example.
Here's what I mean:
http://jsfiddle.net/L87PE/1/
Having done that, you could even give them widths as a percentage, eg. width: 34% and width: 66%, and have them fill the whole browser:

How to display PDF file in HTML?

I have an auto generated PDF file by itext and I need to display that PDF file in HTML. My question is: How to display a local PDF file in HTML using pdf.js? Should that PDF file be generated by some standards?
Implementation of a PDF file in your HTML web-page is very easy.
<embed src="file_name.pdf" width="800px" height="2100px" />
Make sure to change the width and height for your needs.
I use Google Docs embeddable PDF viewer. The docs don't have to be uploaded to Google Docs, but they do have to be available online.
<iframe src="https://docs.google.com/gview?url=https://path.com/to/your/pdf.pdf&embedded=true" style="width:600px; height:500px;" frameborder="0"></iframe>
1. Browser-native HTML inline embedding:

frameBorder="0"
scrolling="auto"
height="100%"
width="100%"
></iframe>
Pro:

It’s the fastest solution
Cons:
It doesn’t work on mobile browsers

you can display easly in a html page like this
<embed src="path_of_your_pdf/your_pdf_file.pdf" type="application/pdf" height="700px" width="500">
In html page for pc is easy to implement
<embed src="study/sample.pdf" type="application/pdf" height="300px" width="100%">
but pdf show in mobile by this code is not possible you must need a plugin
if you have not responsive your site. Then above code pdf not show in mobile but you can put download option after the code
<embed src="study/sample.pdf" type="application/pdf" height="300px" width="100%" class="responsive">

The element is supported by all browsers and defines an embedded object within an HTML document.
Bottom line: OBJECT is Good, EMBED is Old. Beside's IE's PARAM tags, any content between OBJECT tags will get rendered if the browser doesn't support OBJECT's referred plugin, and apparently, the content gets http requested regardless if it gets rendered or not. Reference

Update - Adobe PDF Embed API
Adobe released their Adobe PDF Embed API which is completely free. Since they created the PDF format itself, their API is probably the best for this.
It delivers the highest quality PDF rendering available.
You can fully customize user experience and choose how to display a PDF.
You will also have analytics on PDF usage so you can understand how users interact with PDFs, including time spent on a page and searches.
All you have to do is create an api_key and use it in the code snippet.
Displaying PDF as buffer (local file for example)
Here is the example of the code snippet that you can just add to your HTML and take advantage of their API for displaying PDF if you have the buffer (local file for example).
<div id="adobe-dc-view"></div>
<script src="https://documentcloud.adobe.com/view-sdk/main.js"></script>
<script type="text/javascript">
document.addEventListener("adobe_dc_view_sdk.ready", function(){
var adobeDCView = new AdobeDC.View({clientId: "api_key", divId: "adobe-dc-view"});
adobeDCView.previewFile({
content: { promise: <FILE_PROMISE> }
metaData: { fileName: "file_name_to_display" }
}, {});
});
</script>
You can use
<iframe src="your_pdf_file_path" height="100%" width="100%" scrolling="auto"></iframe>
Or, if you want to make it take up the whole page:
Link
I understand you want to display using HTMl but you can also open the PDF file using php by pointing out the path and the browser will render it in a few simple steps
<?php
$your_file_name = "url_here";
//Content type and this case its a PDF
header("Content-type: application/pdf");
header("Content-Length: " . filesize($your_file_name ));
//Display the file
readfile($your_file_name );
?>
The answer provided by gofilord is right but I might also add that if you create an empty bucket to pour your pdf into you should give it a src="" like...
<embed id="fooEmbed" src="">
...in the HTML and in the javascript...
document.getElementById('fooEmbed').src = 'bar.pdf';
...it will work. If instead you do this...
<embed id="fooEmbed">
...it will not work.
If you're working with a local file this is the solution that worked for me.
const objectUrl = URL.createObjectURL(file);
<iframe src={objectUrl} width="100%" height="100%" />

Iframes in HTML noob

My (fan) website has this code so far. I want the crop I have specified (-360px on the top and -50px to apply to each iframe, but no matter WHAT I do the other three iframes do not have the crop). Is there a way to make the crop apply to all the iframes? I am completely lost. :(
<div style="overflow: hidden;
margin-top: -360px;
margin-left: -50px;">
<iframe src="http://dragcave.net/view/XD" frameborder="0" width="750" height="450" " scrolling="no"></iframe>

iFrames only show the whole page, there's not really any way for you to only show part of a page in an iframe.
What you need to do is some jquery trickery, which you can find here: iframe to Only Show a Certain Part of the Page

Iframe preventing rest of page from loading?

I have an iframe loaded within a page. This code works fine in firefox but not in ie - it does not load anything following the iframe. If i move the iframe to the bottom of the page everything loads correctly. Has anyone encountered this error before?
head----
<style>
iframe{
margin-left: 22px;
height: 112px;
width: 612px;
}
body{background-color:transparent}
</style>
body---
<img align="left" border="0" src="http://picurl.com"/><br />
<p>text</p>
<iframe frameborder="0" src='http://URL.com'</iframe><br />
<p>big load of text</p>
Text loads fine, content of iframe loads correctly but 'big load of text' does not. Why does this happen? I am using internet explorer 8 for this task, can't change this.
You missed a > from the end of your iframe tag:
<iframe frameborder="0" src='http://URL.com'></iframe>

IFrame scroll bars not coming on Chrome

I am using an IFrame to make show some content from some other domain. The problem is that I can use a specified height and width (which I am using) and the content inside the IFrame cannot be accommodated completely in the IFrame. Hence, I need scrollbars.
I used the following html code -
**<iframe style = "overflow-x:scroll; overflow-y:scroll;" src = "http://shopsocial.ly/merchant/fanpage?merchant_name=cafepress"
height = "400" width = "500">**
This works fine in Firefox. But in Chrome I'm not getting any scrollbar in the IFrame. I have searched this problem and have tried many things all of which did not solve my problem. Can someone help me with this?
In your iframe content add inline:
<body style="overflow:auto;">
or in the css file attached to the iframe
html, body {
overflow:auto;
}
and of course as recommended by Tom make sure you use scrolling="yes" and style="overflow:visible;" on the iframe:
<iframe scrolling="yes" src="http://example.com" style="overflow:visible;"></iframe>
If it still does not work then try to wrap the iframe like this:
<div style="overflow:visible; height:400px;">
<iframe scrolling="yes" src="http://example.com" style="overflow:visible; height:2000px;"></iframe>
</div>
Instead of using the CSS style you could use the scrolling property of the iframe and set it to yes (i.e. always display scrollbars):
<iframe scrolling="yes" src="http://domain.com" height="400" width="500"></iframe>
Yap Tom is absolutely right you can use
<iframe style="overflow:visible; width:400px; height:400px;" frameborder="0" scrolling="yes" marginheight="0" marginwidth="0" src="yourfile.html"></iframe>
and it should be work as i have tested.
If it still does not work then update Chrome to latest version. :)
To make this scrollable on all mobile devices (specially iPhone devices), you will need to add CSS to the div around the iframe:
<div style="overflow: auto!important; -webkit-overflow-scrolling: touch!important;">
<iframe scrolling="yes" src="http://example.com" height="400" width="500">Loading...</iframe>
</div>
