What is the best way to dynamically change the width and height of an HTML5 video within a webpage? The kind of behaviour I'm referring to is the same thing in the intro video of http://flipboard.com/
When the window is resized, the video still takes up 100% of the viewable size (without scrolling). I noticed that the video gets resized to a certain degree, but stops resizing and gets cropped at some point.
What is the best way to get the same behaviour? I want to have a video take up the entire viewable area of the browser without scroll bars. This is only on a desktop/laptop, I am not considering any mobile devices ATM.
What I have in mind right now is to dynamically change the width/height properties of the video to fit the viewable area using javascript, but also set a minimum size such that the video doesn't get distorted. The video can be placed in a container that is always centered, so if the browser gets to a size that is too small, it effectively gets cropped. I'm not sure if this is too long-winded and if there is an easier way.
Thank you.
It looks like they have the css properties of height and width set to 100%. If you use an element inspector like the one built into chrome or firebug for Firefox, you should be able to see exactly how they structured the html/css for the video element as well as the div its nested in. Then, as you said, also set a min-width/min-height property.
Unless I'm misreading your question, it should be that simple. Hope this helps!
you could do it with "Responsive CSS", there are some ways to do that,
you could set the viewport, max-width, min-width, etc.
This link have a nice explanation how to do that : http://kyleschaeffer.com/best-practices/responsive-layouts-using-css-media-queries/

I'm running into a problem. When I view my website on a computer and phone, it's built perfectly; but, when I pull it up on an iPad, the background images are like blown up. My website is http://www.zwdalpha.com/, any help will be very appreciated! Also, my Github is https://github.com/zcsmouse970/zwdalpha
To address the issue, you first need to understand what is happening. Background image sizes are handled with the background-size attribute, which you currently have set to cover. cover is great for large screens because it makes sure the image "covers" the height of the element. This allows for clipping on the sides to make sure it fills from top to bottom. contain is the opposite of that. It makes sure you can see the entire image at all times. It does this by making sure the width is 100% and the height is left to clip or expand. When you see on tablets and smaller that the images are "blown up", the CSS is making sure that the entire content area is filled with the image, and it does this by making sure the height of the image fills the content pane. Here's where we get a little more detailed.
You have your images setup as fixed. Obviously this was the effect you were going for, but lets think about what needs to happen here. Now the image needs to be covering the screen from top to bottom because it is able to be viewed anywhere the content pane is while being fixed. So now your image is covering the entire viewport. You can see the changes it makes when you change it to background-attachment:scroll;. It instead fits the image into the content pane instead of the viewport.
All of that being said, the way you can change this is by implementing media queries and switching backgrounds to cropped versions that are more appropriate to the viewing dimensions.
Your issue appears to be to do with background-attachment: fixed not behaving as expected.
Try background-attachment: scroll

So my wordless theme has a built in slider. It is responsive. The slider is in the background and seems to have a height of 100%. On browsers that are normal width but tall this means that a lot of the image is hidden behind the white background of the content lower down the page. If you resize the page while the slider is on the slide image of the queen you will see why this is a problem. My boss would like it to always show her heard and shoulders.
Is there a way of, on longer shaped browser windows, stopping the image from being 100% height and therefore making it display better on longer height browsers as well as normal shaped ones?
As you can probably tell I'm kind of out of my depth on this one, so any help would be fantastic!
Thanks
Luckily for you there is a quick fix on this particular slider. The elements are set to have a background-attachment of fixed on #slider-container .full-bg-image. Clear it and the whole picture will display. You should then be able to use the background-position to align more specifically for mobile, or only have the fixed position for desktop use with a media query. I'm not sure what method the powers that be would like best :)
I've looked and there doesn't appear to be another post the is exactly what I am looking for, and I am on a deadline to make this work so lets see if I can explain it better.
We have one page in development on a Drupal site that uses Panels and Views Slideshow. There are a lot of absolute and fixed position elements because of where they need to be on the page. The parent div needs to have a width and height of 100% to fill the page. Keeping in mind that the point of this page is to not have scrollbars and present everything to the user no matter what screen size they are on. So I have media queries cleaning up elements where need be on certain screen sizes.
Though when a user uses their browser to zoom into the page, the elements start shifting and stacking on top of each other. I believe this is because the 100% height/width is adhering specifically to the window size and doesn't expand beyond the window when a user zooms in.
I was able to fix it by removing the 100%'s and replacing them with pixels, but this becomes an issue because if the screen isn't the correct height or width, then you have scrollbars and the user doesn't immediately see everything on the page.
Is there any JavaScript or anything that can utilize the 100% height/width and allow them to expand beyond the page, and turn on scrollbars, during Browser Zoom?
Keep in mind that if a user is zooming in, its OK for the page to spill off and scrollbars to show, but the default screen this is not allowed.
I hope this is OK to show but an example of a page that uses Javascript to scale the entire page is pretty much what I can see myself needing but don't know how.

Any help appreciated and the quicker the better of course :)
This should help. Lets you detect the browser zoom level in mordern browsers.

All,
I am writing the CSS for our web application. The whole application needs to fit in the browser window without any scrollbars appearing. I also want to set a min-height & min-width properties so that if the browser window gets smaller than our min., only then will the scroll bars appear.
Is there a way of achieving this in CSS please?
Your problem depends to the screen size of the viewers, which may varies greatly. My propose is that you should create a fix width/height div which is the wrapper of all the content (usually 1024x768).
If we make fluid layout we can use em or % for font and div width and height to make fluid but how to make images resizable?
I want to make one layout for all sizes and devices
Joel Spolsky managed to find a very easy solution (a small proprietary CSS definition for IE). He found the solution here.
There's no simple solution for this. You can use flexible units for the images just like you can your other page elements. But this will result in inefficiencies and aesthetic issues including excess file size for a tiny image (if you're sizing it down), pixellation of sized-up images, etc. So what you likely want is to start with a large image and scale down to the appropriate size versions, and use Javascript to write out a tag referring to the correct size image depending on context.
Well you can size images relative to the viewport width (eg. img.thing { width: 50%; }, but you don't generally want to. Scaled images will at best (when the browser does bicubic resizing) look a bit blurry, and at worst totally blocky/jaggy (nearest neighbour resizing). You can include some CSS (SVG's image-rendering will be supported for HTML in Firefox 3.6; -ms-interpolation-mode in IE) to try to coax the browsers to use the better scaling mode, but it's far from reliable and still the best rendering isn't that great.
In addition, CSS background-images cannot be resized at all (yet; it is proposed for CSS3 but you'll have a long wait).
Liquid layout generally aims to adjust the distances between fixed-size images to respond to changes in viewport width, rather than scale the whole page including images. The user can, at least in modern browsers, zoom the whole page including images themselves, taking the image quality hit if they need to.
I reckon you will have to make use of the canvas element from HTML5. Or you could have some JavaScript that sets the size of the image tag but you would have to do some math to figure out the correct proportions.
