I. First introduce the PXPX is the most basic length of the CSS, the unit with PX do not have any problems, you can make the page according to the precise presentation of the routine!But it is! But, but! If the entire use of PX layout will hide an egg pain problem, that is, when the user and Ctrl roll the page (white is ctrl+,ctrl-), you will find the page structure produced unpredictable confusion, so there are bricks advocate using em instead of px

coefficient between 1pt and 1sp can be set to X, 1 * density_device/72 = x * 1 * density_device/160 => X = 160/72 = 2.2222 That is to say, in Android, 1pt is roughly equal to 2.22sp (3) relationship and Difference Past,ProgramUsers usually design the computer user interface in pixels. For example, define a form field with a width of 300 pixels. the spacing between columns is 5 pixels, And the Icon size is 16 × 16 pixels. The problem with this processing is that if you run the prog

PxPixel (pixel), which represents a physical pixel point on the screenIt is not recommended to use the px drawing UI directly, because the px actual size displayed on different phones will be different for the UI drawn for units affected by pixel densityDP (used to define the size of the control)Density-independent pixels. One of the virtual pixel units that Android recommends is to have the same effect on

and SP take the same value of 1, you can set the coefficient of x between 1pt and 1SP, 1 * density_device/72 = x * 1 * density_device/160 =gt; x = 160/72 = 2.2222 Which means that in Android, 1pt is about 2.22SP. =================================================================== What is dip and SP In the past, programmers used to design computer user interfaces in pixel units.

I. Overview of UI interfaceUI, a very important part of the user interface for an app, is the face of the app, and the user's first impression of the app comes from the interface, so it's hard to retain users without a perfect user interface.A good user interface will greatly improve the user's desire to use and maintain customer loyalty, like a connotation of the girl with a beautiful face, this will let many gentlemen remember.All UI components are called view, generally divided into two categ

You can set a color. The general syntax of notation is #aabbcc. And there are no spaces, commas, and other separators between three numbers.H1{color:rgb (255,255

A unit of relative length:The relative length is measured by the relationship to other things. A total of 3 relative length units: em,ex,px.1 "em" is defined as the value of a font-size of a given font, for example, a font-size of one element is 14 pixels, and for that element, 1em is equal to 14 pixels.Ex refers to the height of the small write x in the font use
