How to make website responsive to current screen aspect ratio? - html

As the title says how do you make a website responsive to the screens aspect ratio? So if it's 16:9 it'll look one way, but if it's 9:16 it'l look another way.
I've only tried setting a max/min width/height but I realized it wouldn't actually consider the aspect ratio just the screen size. So if a smartphone had a 1920px width it would look the same as a normal 1920p monitor, which would obviously be a problem.

Scaling parent div and all it's children while maintaining parent's aspect ratio

I'm trying to create two sections website. First is a part with inputs and the second one is 'preview part' showing these informations in adjusted way.
The important part is that the preview part is supposed to keep A4 page aspect ratio, while the input part can be stretched freely. How can I scale the preview with all children components so that it always fits screen width while keeping it's aspect ratio? I'm using bootstrap.
website on desktop - no problem
website on smaller screens - without scaling width of the page is to big

Viewport width having no effect?

Quick Overview of my Problem:
I made a site for mobile, it looks great. Move on tablet it looks horrible. As in it's like 5x stretched out from left and right. Imagine your face stretched horizontally up to 4ft.
Research and Possible Solution
I had a feeling i could viewport. As I thought, if i could just SCALE the layout instead of having browser provide more width and then my layout spreading to accommodate.
Article told me that if i set viewport meta tag width=300 or anything custom then browser scales whole page to fit the current viewport's actual width so 300px would be covering 1200px, at least that's what my impression was.
However, it DIDN'T work. No matter what viewport settings I do they appear to have no effect on scaling.
What i want
I want my page to scale up. I don't want to specify every border width in em units than create dozen media query checkpoints to increase font size. Especially since my layout remains the same only it needs to scale up.
If i was going after different layouts then obviously i'd've used media queries.
I've tried this:
<meta name="viewport" content="width=300">
I solved it using some javascript
first add (i'm using jade)
meta(id="myViewport", name="viewport", content="width=device-width")
Now window.innerWidth will give correct browser width and not some arbitrary number set by browser like 960 which was being reported by chrome on 360 width phone and 2100+ tablet.
Now just check if screen is wide then limit the viewport's width that way browser will scale it up so, for my tablet, 500 pixels will take up 2100 pixels.
if (window.innerWidth > 450) {
var mvp = document.getElementById('myViewport');
mvp.setAttribute('content','width=500');
}
//- first set device width so window.innerwidth shows actual width then change accordingly.

Is it possible to resize a web page for different screens resolutions while maintaining a preset aspect ratio set by a given height and width?

I have set the height and width of my parent div to:
width:1060px;
height:650px;
Which gives me an appearance as far as its size in Chrome on my 720 laptop but when I plug the 1080 TV through the HDMI it's too little on the screen.
I wonder if there is a way to resize the parent div to keep the same distance I get from top/bottom/right/left for 16:9 ratio.
Yes, you need to trigger a resize on the container each time on orientation change with js, then calculate your designed width height aspect ratio, then resize your container to screen.height, then multiply your screen height * your desired aspect, then that result is your width, then check if your width is not minor than screen width, if not is good, if true make the same but in backwards, dividing screen width / desired aspect ratio. lastly center your container in the screen with js or css.
that is the idea, i know works because i ve done it, probably there will be an easy way to accomplish the same.
In this way you can build percentually inside the container and will allways look the same in any kind of stuff, the only change will be a strip on the width or height depending your aspect ratio and your device specs, but it will be allways at biggest possible way.
EDIT,
Is something like;
var ratio = 1060/650;
$(window).on('resize', function() {
$('#container')
.css({width: screen.width + 'px', height: screen.width*ratio + 'px'});
if ($('#container').height() > screen.height) {
$('#container')
.css({width: screen.height/ratio + 'px',height: screen.height+'px'});
}
$('#container').css({left: (screen.width - $('#container').width()) / 2+'px',
top: (screen.height - $('#container').height()) / 2+'px'});
});
In jsfiddle wont be nice as this is using screenwidth (you could also use innerHeight, depends if you are going full screen).
Didnt test it but thats the general idea
What you want is a responsive design. In order for your page to resize, you have to start using percentages instead of fixed widths.
For example, change your width:1060px; to width:90%;. The height can stay the same, but if you wanted it to get taller, you can set height:100% and that adjusts according to the content on the page.
Also, instead of using px for text-size, use em. em is like percentages for text.
Here is a great tutorial that helped me a lot with responsive design.
Use CSS media Queries to specify styles for different screen resolutions & sizes. Your browser will choose the respective style depending on the size of the view port.

fluid portrait images with max height

I'm having some issues with fluid images when using a max height. I'm trying to bound the image in a box that is at most 450x450 or any arbitrary box thats not in the same aspect ratio as the image. What's happening is that the width of the image is being restricted to 450px but the height is not and the image is overflowing the wrapper div.
my code is:
<div class="wrapper">
<div class="container">
<img src="http://i.imgur.com/iw4yOa0.jpg"/>
</div>
</div>
see http://jsfiddle.net/5fuZ5/ for full code and css.
I know I could achieve this by using jquery but I need a responsive solution that doesn't require javascript.
OK i've got a similar issue and could find nothing to help. My situation is that i have a single column of images that are fluid (fit their container 100% in width) works fine for landscape images but portrait are huge as its the width being fitted, therefore tall and skinny image (portrait) is having its width fit to container thus making it massively tall.
My solution was to think about the container, if in the instance of a portrait image i set the container to be 50% of the landscape container then when i fit the images width (when portrait) to a smaller container i get them proportional (ish).
So wat you want is 2 containers to use, one for portrait and landscape, the landscape one will be the maximum width you want so 450px. Now make your portrait container half a width so 225px (half of the width) if all your images are the same aspect ratio then they should all match nicely and give you a structured grid - or if single column the portrait images will be more or less as tall as the landscape images are wide.
If you want to see this working (for a short time) I'll leave this link up so you can see how i solved it. The example is an email (please don't moan about poor coding, its not finished) template I'm making, where i have a single column of images (its responsive) both portrait and landscape - use a class on the table that contains the portrait image (class=portrait) but this could easily be a div.

My main point is to stop thinking about trying to control the height, just control the container, let the image fill it, and by adjusting the width of the container (making it smaller) you naturally reduce the height of the image.
Aspect ratio of the images in general will ensure you can predict the layout as you have a baseline of sorts - portrait images relate to the landscape ones.
Hope this helps or at least give you another idea.

Responsive design site title, and slider block

I have just make a responsive design, but there are 2 mistakes. One that when window is resized to different size, entire website will automatically resize, but Heading title and slider doesn't resize. But if i reload it, it will resize.
I have made different css rules of font sizes and slider height, which don't work without reload. You can see online website at: http://www.itmediagroup.lt you see slider, change window size, then u will see a problem, when reload website, and see all changes, I think all bugs are on my css, but i dont know how to fix it.
P.S fontsize i was trying to do in percent, but then the size of font is too small.
You can either set font sizes for elements using media queries, javascript (fittext.js) or you can use css viewport units. For example;
Viewport unit syntax
1vw: 1% of viewport width
1vh: 1% of viewport height
1vmin: 1vw or 1vh, whatever is smallest
1vmax: 1vw or 1vh, whatever is largest
It is supported by most new browsers but can be made more "bulletproof" by using VminPolly
