DPT was written to help me check my own screens (Couldn't find one that worked across multiple desktops so had to write my own!) by cycling through the three primary colours used (red,green,blue) and all on (white) and all off (black).ġ) Ensure your screen is free from dirt and marks,if possible clean it with correct recommended products.Ģ) Make sure your screen resolutions are correct for your monitor, e.g. There's only a slim chance that all of these will be perfect more likely, some will be stuck on (creating a "bright" defect) or dead (resulting in a "dark" defect). NEW VER 3.00 - TFT screens have thousands of pixels, on a 1024x768 monitor, there are three cells for each pixel - one each for red, green, and blue - which amounts to nearly 2.4 million cells (1024x768x 3 = 2,359,296). devicePixelRatio > 1.Dead Pixel Tester, with display tests. For example, suppose you wanted to go from a vertical layout to a horizontal layout based on orientation.įirst, set CSS properties to default to portrait. One of the main CSS features you'll want to use is media queries.Ī media query is a way of applying CSS to elements based on a device's characteristics. Here we will look at some simple examples of how you can adapt your UI and images, but if you want to dig in to other topics then this article on HTML5Rocks is a good point of reference. Responsive design is the notion of changing your UI depending on the dimensions of the screen size.

In addition to doing this, you may want to use the new layout algorithm TEXT_AUTOSIZING introduced in Android 4.4, which increases the font size to make it more readable on a mobile device.
If these methods are not set and no viewport is specified, the WebView will try and set the viewport width based on the content size. In this case, you need to force the WebView to use a desktop-size viewport: In some cases, you may need to display content that isn't designed for mobile devices–for example, if you're displaying content you don't control.
However, for reliable and controlled behaviour it's good practice to include the viewport meta tag. Setting width to the special value device-width will give you more control over the page layout.īy default the WebView will set the viewport to device-width, rather than defaulting to a desktop viewport. If you want the width of your site to be 100% of the WebView's width, as shown on the right, you need to set the viewport meta tag: In most cases, the result is a tiny overview version of the page that requires the user to pan and zoom to actually read content, like the image on the left. This causes your web page to be given a larger width (typically 980px) and scales it to fit the WebView's width. Without it, the WebView may act as if your site is designed for desktop browsers. The viewport meta tag is of the most important tags you need to add to your web app.
There are a number of options you can use to create the perfect UI, this article will outline some of the best practices for the mobile web in general and then some specific tricks you could use for hybrid applications.
