I use the live streaming broadcast rtmp function.
I want to add css to make my live streaming broadcast in rtmp on youtube prettier. According to the documentation, the css properties are limited. I tried to see the properties "border and background-color" but I had an error response, so it blocks well.
Is there another way for me to improve the graphical aspect of my content on youtube?
To summarize how can I add graphic elements to my live content rtmp youtube.
[EDIT]
The request body and CSS I Tried :
broadcast {
position: relative;
padding:0;
margin:0;
width: 1280px;
height:720px;
overflow: hidden;
}
stream:first-child{
display : inline-block;
width: 49%;
height: 99%;
z-index: 2;
}
stream:first-child + .stream {
position : absolute;
z-index:1;
width : 20%;
height : 40%;
top : 30%;
left : 40%;
}
stream:last-child{
display : inline-block;
width: 49%;
height: 99%;
z-index:2;
}
The error OpenTok is giving
error 400 Stylesheet has unsupported features
What is the layout you want to show
In finally a layout with 3 block, 2 in horizontal and one more small in center and in first plan.
What do you mean with add graphic elements
I want the opportunity to decorate my content. Example of graphic element: borders, background color, logo addition, image, graphic text etc...

I have an <img> that shows a remote image.
I want it to fallback to another local image, in the case where the remote one is not reachable.
<img class="cc_image fallback" src="http://www.iconarchive.com/download/i82888/limav/flat-gradient-social/Creative-Commons.ico">
.cc_image {
width: 256px;
height: 256px;
}
.cc_image.fallback {
/* this URL here is theoretically a local one (always reachable) */
background-image: url('https://cdn2.iconfinder.com/data/icons/picons-basic-3/57/basic3-010_creative_commons-256.png');
}
It works so that when the src image is not found then the background image will be shown.
The drawbacks are:
it will always load the background image (additional HTTP request)
it shows a little not-found-icon (a question mark on Safari) at the place of te original image, that is displayed above the background-image (not a big issue, but I'd like to get rid of it)
How could I solve these issues?
Or: are there other technics to achieve the same result?
I found this question but the given solutions rely on Javascript or on <object> (that seems to not work on Chrome). I would like a pure CSS/HTML solution, without Javascript if possible.
I know about the multiple background-image but am not sure whether it is a good option (browser support? and will it fallback with an unreachable image?).
Or I was thinking about embedding a SVG image as data-uri.
Suggestions for the most flexible (and compatible) method?
Unfortunately, you can't achieve both without Javascript or object tag.
You could do this to avoid the missing image icon:
Place your image in a container (it might already be in one).
Make the container have the same width and height as the image.
Set the fallback image as the background image of the container.
Set the remote image as the background image of your img tag.
Load an 1x1 pixel transparent png as the src of your image (see code for how that can be done without an extra HTTP request).
Code:
HTML
<!-- you could use any other tag, such as span or a instead of div, see css below -->
<div class="cc_image_container fallback">
<img class="cc_image" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" style="background-image: url(*your remote image*)"/>
</div>
CSS
.fallback {
background-image: url(*fallback image here*);
display: inline-block; /*to ensure it wraps correctly around the image, even if it is a a or span tag*/
min-width: specify a minimum width (could be the width of the fallback image) px;
min-height: specify a minimum height (could be the height of the fallback image) px;
background-position: center center; // fallback for older browsers
background-size: cover;
background-repeat: no-repeat;
}
.cc_image {
min-width: same as container px;
min-height: same as container px;
background-position: center center; // fallback for older browsers
background-size: cover;
background-repeat: no-repeat;
}
min-width and max-width make sure that the background images remain visible.
background-position makes sure that the central part of the images remains visible and is a graceful degradation for older browsers
background-size resizes the background image to fill the element background. The cover value means that the image will be resized so it will completely cover the element (some of the outer edges of the image may be cropped)
The base64 data in the img src tag is a transparent 1px png.
This will have an additional benefit that regular users and some bots may not be able to save your images (a rudimentary image protection)
The only drawback is, that you will still have one extra HTTP request for the fallback image.
I have found a solution on Codepen, which I would like to share with you:
https://codepen.io/anon/pen/Eqgyyo
I prefer this solution, because it works with real image tags, not background images.

I've been working on a theme for the site http://silversoundz.com and have it looking just how my client wants it on browsers but the problem comes when I shrink the screen to check the site on mobiles, in particular the Iphone.
It seems like there's a minimum threshold (around 768px width) before the header+icon svg files go back to their enormous default dimensions thus rendering everything else tiny in relation to that. I've changed the icons to smaller pngs but I'm not sure what the best course of action is for resolving the header scaling/sizing so everything is proportional on a small screen.
Here's the problematic css
media="all"
#media only screen and (min-width: 768px)
.logo-img {
width: 100%;
float: left;
margin: 0;
position: inherit;
}
Ok I figured it out:
Basically I just had to find the relevant bit of css which was only kicking in for screens > 768 and re-paste it below the general styles which says:
body {
font-family: "Open Sans", sans-serif;
font-size: 1.0em;
color: #000000;
background: #ffffff;
font-weight: 400;
min-height: 100%;
}
.wrap {
width: 96%;
margin: 0 auto;
}
so it would come into affect for the general styles too.
I often float images either left or right around text on desktop but I want them centered for small mobile devices and the paragraph to drop below the image using Responsive design. I've got the paragraph dropping below the image using an online mobile viewing device but not when I try to view it via my computer. The image won't center online or on my computer.
Here is what I have found after many hours of research:
I have this set up for all images:
img{
border:0;
max-width:100%;
height:auto;
}
I have this set up for all paragraphs: it pushes the paragraph down below a floated image when the width of the paragraph is less than 10em (about 200 px).
p:before{
content: "";
width: 10em;
display: block;
overflow: hidden;
}
I have applied the following for images to media queries less than 320 and max of 480:
img{
max-width:100%;
display:block!important;
margin:0 auto !important;
float:none !important;
}
(i had to add !important to some of them or they wouldn't take but it's still not accepting margin: 0 auto; )
Can anyone see what I'm doing wrong?
Here you have a working update of what you need: http://jsfiddle.net/ancpjmet/3/
I changed min-devide-width to min-width and max-devide-width to max-width to be able to see the changes on my desktop browser in Google Chrome.
You have to set the div wrapping the img to float: none;, not the img:
#media only screen and (min-width:320px) and (max-width:480px) {
#image-wrapper{
float: none !important;
}
#image-wrapper img{
max-width: 80%;
display: block;
margin: 0 auto;
}
}
I also rebuild your .clearfix class to be more consistant and work in all browsers:
.clearfix:before,
.clearfix:after {
content: '\0020';
display: block;
overflow: hidden;
visibility: hidden;
width: 0;
height: 0; }
.clearfix:after {
clear: both; }
.clearfix {
zoom: 1; }
Take a look at the changes in the jsfiddle given.
For my website this is what I am using for the image with regards to responsive design:
.logo {
max-width: 100%;
display: block;
height: auto;
margin-left: auto;
margin-right: auto;
}
The image scales properly width wise but the image's height is too big. In these kinds of situations what can one do to make the image scale properly? If I remove height auto and assign 70px the image looks good when viewed in full version but as you begin to shrink the size of the browser the image looks like it's going inwards.
HOw can i fix this?
try this:
{
max-height: 100%;
max-width: 100%;
height: auto;
width: auto;
}
for this wrapp a div around img and apply the height you want and overflow hide it
.imgwrapp {width:100%;height:70px;overflow:hidden;float:left}
So given the css you have there, the ratio of width to height of the image is what's giving you problems. If you don't like the height of the image when the browser is wide, then you should probably get a different image/crop it. When you set the height to 70px what you're doing is forcing the image into a box that it doesn't fit in, so the image will look funny as it's being scaled weird.
But alas there is another option. here is a jsfiddle that shows only the amount of the image that fits within my first n pixels (in your case 70) so that way it will kind of slide out of view. Check the css here :
.header {
width: 100%;
height: 100px;
overflow:hidden;
}
.everythingelse {
width: 100%;
height: 200px;
}
for the reference: Check this:

I'm creating a website for mobile (it's pretty sure not the best way to do it.. but anyway) I'm using percentages all the way, since it should be relatively equal in size on any mobile (portrait) screen.
I've tried numberous things, such as:
#header img {
vertical-align:middle;
padding-top: auto;
padding-bottom: auto;
margin-top: auto;
margin-bottom: auto;
}
But I still can't get it working.
The only thing that will be in that div is that single image, which presents the school logo.
Thanks in advance!
Use your image as the background of your #header id:
#header img {
background:url(your_image.jpg) center center no-repeat;
}
remove width and height from img tag and
#header{text-align:center;}
