With HTML5 documents to make the page on the effect of the PC is no problem, but the mobile browser will zoom to the page is very small, you can see the entire page but can't see the word!! Just add the META tag to the Page Head tab viewport statement: can help you solve this seemingly bad problem. Viewport Syntax Introduction: Content= "Height = [Pixel_value | device-height],width = [Pixel_value | device-width],Initial-scale = Float_value,Minimum-scale = Float_value,Maximum-scale = Float_value

= [Dpi_value | device-dpi | high-dpi | medium-dpi | low-dpi] 11 " 12 /> WidthControls the size of the viewport, you can specify a value or a special value, such as device-width as the width of the device (in pixels of the CSS when scaled to 1

category). So after android3.2, this classification is not used, the new classification method is defined by the available screen width, in the project resource file (such as layout) use, here are some examples: LAYOUT-SW600DPLAYOUT-SW720DPVALUES-SW340DP the definition of these classifications will be explained in detail later, now we have a concept.Screen densitiesThere are several concepts to understand before you speak screen densities: px,ppi,dpi

Today, my friend uses Photoshop to process the picture to save the specified size, but she only to the centimeter to shape the sense, but in the software to save the picture does not have this unit, can only save the units of pixels; Other software can only be saved in inches. I went to the internet to find the next information, finally found the conversion formula, special record:) 72 Megapixels/inch = 28.346 px/cm300 megapixels/inch = 118.11 px/cm1 cm = 0.3937 inches1 inch = 2.54 cm First of a

resolution does not mean the aspect ratio of the screen. In Android systems, the program generally does not directly process the resolution. DensityPixels arranged along the length and width of the Screen Based on the screen resolution.Low-density screens have only a small number of pixels in the long and wide directions, while high-density screens usually have many-or even very many-pixels arranged in the same area. The screen density is very important. For example, the interface elements (suc

Pre-development knowledge supplement: length units and screen resolutions of Android, which are also reproduced ~~, Android screen resolutionThis article is a bit early, but it is very practical. For more information about the Unit, see the red part. Screen Resolution Basics 1. terms and concepts Terms Description Remarks Screen size) It refers to the actual physical size of the mobile phone, such as the commonly used 2.8 inch, 3.2 inch, 3.5 inch, 3.7 inch

Knowledge required for mobile webapp development and webapp Development There are more and more mobile devices, and more than 1.3 million android mobile phones are activated every day. Therefore, our webapps for mobile terminals are also starting to follow up. This article describes the knowledge and experience of webapp development and debugging, and provides several optional solutions.I. Basic concepts (1) CSS pixels and device pixels CSS pixels: the abstract unit used by the browser to draw c

PX (pixel) pixels, that is, the display point on the screen, in (inch) inch, per inch = 2.54 cm, we often say that a few inches of mobile phones, refers to the phone screen diagonal is a few inch, dpi (dots per inch) the number of pixels, 320x480 screen, If the width is 1 inches, the horizontal dpi is 320/1 (wide), and if the height is 1.5, the vertical dpi is 48

size to display the maximum page pixels, such as in this window can display a 800-pixel page, the page is designed to 800 pixels, the full display, This window you can understand as the picture, the picture looks the same size, but their pixels may not be the same, that is the meaning.You can define the properties of the window in the For example, in the following paragraph from the HTML code, it sets the window size exactly matches the width of the device screen, and the zoom function is disab

which the user is allowed to zoom.User-scalable: Whether the user can manually scale Width Sets the width of the layout viewport , as a positive integer, or the string "Width-device" Initial-scale Sets the initial zoom value of the page, which is a number that can be taken with decimals Minimum-scale Allows the user's minimum zoom value to be a number that can be taken with decimals Maximum-scale Allows the user's

before I do, I'm going to introduce a little trick for a friend who is designing with PS.As I said before, we want to think about the interface in logical pixel size. Embodied in the design process, is to set the unit into a logical pixel. Open the PS Preferences-unit and ruler interface to change the size and text units to point. The point here is PT, which is used by the organization, whether it's iOS, Android or Web apps. Of course, the name of each platform unit should be remembered. Here w

See the responsive design in bootstrap.The complete viewport syntax is as follows:-name= "Viewport" Content = " height = [Pixel_value | device-height], width = [Pixel_value | device-width], Initial-scale = Float_value, minimum-scale = float_val

different phones, such as a 96*96 pixel control that looks smaller in the overall UI in the increasingly high-resolution phone.ImageAppears similar to this, the overall layout effect may deform, so the PX unit is not recommended in the layout file.DP Direct AdaptationFor this scenario, Android recommends using DP as a unit of size to fit the UI.So what is DP? DP refers to a device-independent pixel, a DP-sized unit of control, in different resolutions and sizes of the phone on behalf of differe
