Using Featherlight jQuery plugin and setting text as the content of my lightbox, my lightbox's width is about 80% of the screen: http://goo.gl/4BVzHM. But if I replace the text by a YouTube iframe, the lightbox's width is reduced to 500px or so, cropping the video.
Code:
<a id='open_lightbox' data-featherlight='.lightbox_content' href='#'>open lightbox</a>
<div class='lightbox_content'>
<iframe width="1280" height="720" src="https://www.youtube.com/embed/g7fbe-oV-X0?rel=0" frameborder="0" allowfullscreen></iframe>
</div>
I tried to use the jQuery binding method too:
$( '#open_lightbox' ).featherlight(
{
iframe: 'https://www.youtube.com/embed/g7fbe-oV-X0?rel=0',
iframeWidth: 1200,
iframeHeight: 800
}
);
Same problem.
(also there are thin white horizontal bands above and below the video, I don't understand why)
To remove the background white color
add background: none; to featherlight-content div
To change the width use '!important`
style="width: 600px !important;
first of all: GREAT STUFF!!
SITUATION: The image loaded in my slider are smaller than the slides container. Using "$FillMode: 5" I can make sure that images have the right size to display within the slides-container, but they are centered.
Q: Is there a way to have them align to the right, so that i can display the caption to the left of it.
TRIED: using CSS to align the image: neither
#slides img { float: left !important };
nor
#slides img {
position: absolute !important;
right: 0px !important;
}
did the job.
A:
After some fiddling and around analyzing the actual sourcecode generated by the script i found out that
using #slides results in a coding error as the tag "" is duplicated (for whatever reason) and would therefor give 2 identical IDs, so better use ".slides" / ""
the following CSS does the job an aligns a smaller image to the right of the slide
.slides {
div {
img {
right: 0px !important;
left: auto !important;
}
}
Jssor slider will fill and align image (in following format) automatically according to $FillMode,
<img u="image" src="url" />
To fill image manually by your self, please remove u="image",
<img src="url" />
I'm working on some Google Web Toolkit Code that places an AbsolutePanel on top of an image. The way I'm doing this is to:
wait until the image is loaded (i.e. width/height are >0)
get the absolute coordinates of the image in the viewport using image.getAbsoluteLeft() and image.getAbsoluteTop
Set the position of the AbsolutePanel (a direct child of the RootPanel) to the same coordinates using RootPanel.get().setWidgetPosition(myPanel, imageAbsLeft, imageAbsTop);
This works in Chrome and IE. Strangely, though, Firefox always positions the AbsolutePanel "a few" pixels (I'd say between 1 and approx 10? But it varies from page load to page load) above the image. I'm clueless as to what's causing this. Any hints much appreciated!
A live example of this is here: http://yuma-js.github.com. If you click the "Add Annotation" there's a draggable box, which movement is constrained by the AbsolutePanel. You'll notice that the constraining works perfect for Chrome, but is off for FireFox.
Morning,
well, I did some research how I could overlay an image with a another object too, and found this article: How to overlay one div over another div.
Based on that I made a similar example using SVG and drawing example, where I draw a rectangle around a space station. What I can tell you is, that you don't want to mix pixel and percentage positioning, and if you can, you should use percentage positioning!
Hope this helps somehow.
Here is my example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
<title>SVG Example</title>
<style>
html, body {
margin: 0px;
padding: 0px;
}
#container {
width: 100%;
height: 100%;
position: relative;
}
#navi,
#infoi {
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
}
#infoi {
z-index: 10;
}
#navi img {
}
</style>
</head>
<body>
<div id="container">
<div class="navi"><img src="http://www.bing.com/fd/hpk2/SpaceStation_ROW1605701719.jpg" width="100%" height="100%"/></div>
<div id="infoi"><svg xmlns="http://www.w3.org/2000/svg" version="1.1">
<rect x="65%" y="40%" width="20%" height="30%"
fill="none" stroke="red" stroke-width="2"/>
</svg>
</div>
</div>
<p>This example draws a fullscreen image and places a fullscreen svg element above it. The svg element then draws a rectangle based on percentage sizes,
which is around the space Station. If the browser window resizes, the size of the drawn rectanlge changes as well, to always be on top of the space
station.</p>

I have a HTML code as follows;
<div>Content table with varying height</div>
<div id="buttons">
<TABLE>
<TBODY>
<TR>
<TD>2 buttons here....</TD>
</TR>
</TBODY>
</TABLE>
</div>
And there is a CSS defined as;
div#buttons{
position: absolute;
bottom: 1em;
left: auto;
}
Now there is an issue on the iPad Safari..i.e. The position of the buttons remain fixed/stick to the bottom of the screen...i.e. if the height of the content table above it increases, it kind of overlaps with the buttons at the bottom.
Is there any way by which I can avoid that overlap and instead have it positioned based on the dynamic height content above ?
Try with:
position: relative;
absolute
The element is positioned relative to its first positioned (not static) ancestor element
relative
The element is positioned relative to its normal position, so "left:20" adds 20 pixels to the element's LEFT position
(source)
Relative allows you to adjust the element position relative to the "content above".
With position absolute in Ipad, or Iphone you need of position absolute in elemtent, and position relative inside father, but imporant to function in ipad and iphone is add left:0, or right:0;
I'm developing an internal web app on our company intranet using PHP. One section of the app displays a couple of high resolution images to the user. These images are in the region of 5000x3500 pixels. Each image has an image map (using rectangular areas), and all works fine in the desktop browsers I've tried.
The problem I'm finding, is that when users access the site via their iOS devices, the images are being rescaled by safari on the device, however the image map coordinates are not being adjusted to match.
An example of the HTML being generated by my PHP is as follows:
<img src="largeimage.jpg" width="5000" height="3500" usemap="#examplemap">
<map name="examplemap">
<area shape="rect" coords="0,0,5000,500" href="blah1"/>
<area shape="rect" coords="0,500,2500,3500" href="blah2"/>
<area shape="rect" coords="2500,500,5000,3500" href="blah3"/>
</map>
(The actual rectangle coordinates in the image map are calculated as a percentage of the image size).
I know that safari is resizing the image due to memory constraints on the device, but I need to either find a way of scaling the image map to suit, or replacing the image map with something else that will do the same job. Can anyone offer any advise?
This topic was solved here on stackoverflow: jquery-image-map-alternative
The best idea is to use absolutely positioned anchors (also as suggested by steveax) instead of imagemap.
Update
As this is an old question, you might consider using SVG maps these days. They are supported in all modern browsers, works responsively and are as easy to use as image maps. (thanks to user vladkras for reminder)
Why don't you use Responsive Image Maps instead. This way you can still use poly maps for oddly shaped items.
http://mattstow.com/experiment/responsive-image-maps/rwd-image-maps.html
It's as easy as adding the script. And one line of javascript:
$('img[usemap]').rwdImageMaps();
Nathan's comment is correct. You need to fix the viewport to prevent scaling. Basically, either specify a fixed pixel width, or set the scale to 1.0 and set user-scalable=no
See this document for reference:
http://developer.apple.com/library/ios/#DOCUMENTATION/AppleApplications/Reference/SafariWebContent/UsingtheViewport/UsingtheViewport.html
An alternative to using the area tag is to use javascript with events x/y & bounds for your hit areas.
I ran into this limitation recently on a project where we needed to be able to zoom and this is what I did to solve it:
Split the image up into 4 quadrants
Placed the 4 images into divs with width and height set to 50% and position: absolute;
Absolutely positioned <a> elements within the quadrant's parent element using
percentage values and a high z-index
Like this:
CSS
#map-frame { position: relative; }
.map {
display: block;
position: absolute;
width: 5%;
height: 3%;
z-index: 99;
}
.q {
position: absolute;
width: 50%;
height: 50%;
}
.q img {
display: block;
max-width: 100%;
}
.q1 {
top: 0;
left: 0;
}
.q2 {
top: 0;
right: 0;
}
.q3 {
bottom: 0;
left: 0;
}
.q4 {
bottom: 0;
right: 0;
}
HTML
<div id="map-frame">
<a class="map" href="foo.html" style="top: 20%; left: 20%;">
<a class="map" href="foo.html" style="top: 40%; left: 20%;">
<a class="map" href="foo.html" style="top: 20%; left: 40%;">
<a class="map" href="foo.html" style="top: 40%; left: 40%;">
<div id="q1" class="q">
<img alt="" src="q1.jpg" />
</div>
<div id="q2" class="q">
<img alt="" src="q2.jpg" />
</div>
<div id="q3" class="q">
<img alt="" src="q3.jpg" />
</div>
<div id="q4" class="q">
<img alt="" src="q4.jpg" />
</div>
</div>
Put all the content INSIDE A TABLE. Set to 100% width. The iphone doesnt seem to scale tables... I was struggling with this problem as i had my images just lose, or inside a div.
none of the rect coords links were working. But when i put the whole lot inside a table... Well, just try it and see :)
I dig out this post because I've just found a solution to get image map working on iOS.
Put your map within an anchor and listen click/tap events on it, to check if the target element matches with a map's area.
HTML
<a id="areas" href="#">
<img src="example.jpg" usemap="#mymap" width="1024" height="768">
<map name="mymap">
<area id="area1" shape="poly" coords="X1,Y1,X2,Y2...">
<area id="area2" shape="poly" coords="X1,Y1,X2,Y2...">
<area id="area3" shape="poly" coords="X1,Y1,X2,Y2...">
</map>
</a>
JAVASCRIPT
$("#areas").on("click tap", function (evt) {
evt.preventDefault();
if (evt.target.tagName.toLowerCase() == "area") {
console.log("Shape " + evt.target.id.replace("area", "") + " clicked!");
}
});
Tested on iPad4 with mobile safari 6.0
Do not use Default <img usemap="#map"> and <map name="map"> change it. Like <img usemap="#mapLink"> and <map name="mapLink">. It's working !!!
Simply using a # in the usemap attribute appears to solve the problem on iPhone.
For example <img usemap="#mapLink"> and <map name="mapLink">
My solution was easy. I just assigned a height and width in the DIV's css to match the size of the image and everything worked fine. Original image size was 825 x 1068, so
<div style= width: 825px; height: 1068px;">
...
</div>
Hope it helps.
I solved this with only 1 line of code, no JavaScript. Only CSS, you need to use zoom property to scale your image and everything will work fine, just like this
img {
zoom: 0.3;
}
<img src="largeimage.jpg" width="5000" height="3500" usemap="#examplemap">
<map name="examplemap">
<area shape="rect" coords="0,0,100%,10%" href="blah1"/>
<area shape="rect" coords="0,10%,50%,70%" href="blah2"/>
<area shape="rect" coords="50%,10%,100%,70%" href="blah3"/>
</map>
please try using percentage values inside coordinates
