To best demonstrate see these images.
I have basic constraints but what looks ok on the larger screens does not on the smaller (images shown are 7+ and SE).
I am wanting the same look on both so which constraints are causing my issue here?
If i set a fixed height width on the image then its too big on the SE. How to have auto layout adjust these constraints in relation to the view?
Set an Aspect Ratio constraint to your UIImageView and delete the bottom constraint, plus change your UIImageView content mode property to aspect fit from the attributes inspector.

I am working on an ASP.NET MVC application which uses Bootstrap for layout of the views. The main browser that we support is IE 10+. I have a few data fields that I am using multiline Textareas for. I am trying to achieve a simple behavior; I want to give a certain maximum width for the Textareas (say 700px, even if window is wider), but have the width reduce down for small window sizes.
I set up a special class in my Site.css file for them. But it seems like the only way that I can get the Textareas to use the full 700px width is to use the CSS width property. But when using width, the width does not reduce for narrower window sizes. If I use max-width, the initial size is smaller even for large windows. Isn't there any way to achive my desired effect?
I ended up using width with a percentage of 70% (rather than 700px). That gave me the size I wanted with larger screens. Then, I put in a min-width value of 300px to give me (close to) 100% on smaller screens.
I always wondered how to fix the gap between floating elements if they don't have the same height:
Here you can see a gap between Featured and Notice which I would like to get rid of. (Get's even larger when the screen resolution is larger since the Featured box becomes more stretched and thus the text spreads over less lines)
Maybe important to note that this is the order of the floating left elments:
Featured
News
Headlines
Notice
Layout for smaller screens (this is looking perfectly fine I just wanted to show you what I mean in the following description with inconsistent layout based on screen resolution)
If the design would be consistent I wouldn't mind implementing some kind of grid system but in my case I'm using styles based on screen resolution so at a certain screen resolution the boxes change from 50% to 100% width (no fixed value used here).
I thought that fluid girds might be the right way to go but after checking them (never used them before) they feel rather static and I'm not sure that they can solve this problem.
EDIT:
Sample of the broblem: http://jsfiddle.net/UfVrH/. Note the fixed height values in A-D are only there to simulate content stretching the div.
To fix such an issue you need to calculate the width and height of each element and re-arrange them by positioning them absolutely, luckily for you there is such a plugin that does this, Isotope
I've built a dynamically sized grid layout that can adapt to reasonably in any sized resolution (phone, tablet, desktop) and handle resizing, all while being near pixel-perfect (sorry, I'm OCD -- and I say "near" because my math is broken right now and you can't fit two evenly sized elements inside of an odd sized container without padding being 1px off on one side).
Anyway, below is a link to what I've hacked together with JavaScript. It's an example of what I'm trying to pull off. Resize the width of the bottom pane a bit to see what I'm going for.
http://jsfiddle.net/langdonx/uFW2C/2/
It has some ugly manual JavaScript that's since been ported to Angular, but still the ugly JavaScript that calculates all the styles remains.
So my question... can I pull this off with strictly CSS? Or a lot more CSS and a lot less JavaScript? And by this I mean dynamically sized cells based on the width of the screen?
Here are the business rules:
Max cell width: 320px
Minimum # cells per row: 2
this might be impossible with CSS, so I'd be fine with settling on Min Cell Width: 178 for Chrome on my Galaxy Nexus(whose portait mode is 360px wide)
Cell border: 5px with a 2px outline
Visible margin between cells: 3px (margin is actually 5px, but outline bleeds out)
In this example, I'm redrawing the cells on resize every time, but in my Angular version, I believe that just the styles get updated. That said, I could probably get away with redrawing a table on resize, but I'd only have to calculate the cell width based on the document width, and well... I wouldn't be thrilled to use a table. =[

Media queries
CSS media queries might get you pretty close to a CSS-only solution.
The key concept here is using different layout grids based on the width of the browser, to vary the number of columns.
Media queries are the natural CSS way to change the layout based on the browser width. And they require no JavaScript. If you use a set of media queries -- each one targetting a different range of browser widths -- to control which layout grid is used, then all each grid has to do is be responsive -- percentage widths for each column, and let the content stretch to fill the column width.
Responsive Design
The question then becomes: Is it possible to automatically stretch each piece of content to fill the column using CSS alone? That depends on the type of content, how it's expected to behave when it stretches, and if there's any room for compromise with the graphic design.
Typically, the graphic design for a responsive website has to be tailored to suit the limitations of Responsive Design (with the graphic designers having a rough idea of what's feasible and what isn't). But... whatever can't be done automatically, can be done using JavaScript.
Relevant search terms for attempting to stretch the content: Responsive Design, Adaptive Content, Fluid Grid
Note: "Columns" in this case may simply mean the percentage width used for the floated containers for each piece of content. It doesn't have to mean "physical" columns, in the traditional sense.
Got sample set up here: http://codepen.io/rctneil/pen/myxDc and full page sample at: http://codepen.io/rctneil/full/myxDc
On that sample, I have a header with a .container within it, header is full width and .container is fixed to a particular width.
If you set the width to be 980 pixels or less then the page renders nicely on an iPad, if you set that width to be greater than 980 pixels then you start getting erroneous space on the right hand side.
I thought the default layout mode on iPad was that if an element is wider than the visual viewport, the visual viewport would zoom out until everything fitted and then allow the user to manually zoom into parts of the page. This is how it has worked in the past for me, I am sure.
Anyone know why the site is not auto zooming out to fit correctly?
If you set the height of the page large enough to require vertical scrolling, it will automatically shrink down the width. For example, set the width and height to 2000px on .container, and it shrinks the page appropriately. This probably isn't a viable solution in this circumstance, but it is a interesting observation of iPad viewport behavior.
I would recommend using iOS meta viewport tags. http://developer.apple.com/library/safari/#documentation/appleapplications/reference/SafariHTMLRef/Articles/MetaTags.html
I am using the built in canvas widget (javadoc) and wondering how to make it take the full browser window.
I tried setting 100% width and height and removing all padding and margins, for body,html and canvas.
I have 3 problems:
1. I checked with chrome's dev tools and the clean.css seems to override myproject.css
2. Even after those css rules and removing the margin on the body in the dev tools, there is still a vertical scrollbar.
3. I struggle a bit with the fact that the canvas coordinate space is independent of actual pixel size. The mause events give me pixel location. Is there a way to get events in coordinate space "pixels"?
After another 4 hours of fiddling I found the answer, and decided to share:
1. I saw that the way i used to load css was deprecated so i used client bundle
2. This was my main problem, solved by explicitly disabling scrollbars
Window.enableScrolling(false);
3. setting just the coordinate space will automatically adjust pixel size to it.
So basically for a full window canvas: 100% width and height and 0px margin in css for html and body. Adjusting coordinate space to client size in the on resize event and explicitly disabling scorllbars.
