The full name of PDA is personal digital assistant, that is, personal digital assistant. It is generally called a handheld computer.
PDA is a self-developed industry. There are also handheld computers with only PDA functions without mobile phone functions on the market.
There are several simple standards for dividing PDA mobile phones and ordinary smart phones.1. The current PDA mobile phone should be a

Sometimes the problem of a sudden disappearance of text or background images is encountered, and the refresh appears again, which is more likely to occur near the floating element (note: not seen). At this point, you can set the vanishing element: position:relative, and if not, consider specifying a width for these elements.

Invisible TextFor whatever reason you want some of the page text to not be displayed in the browser, for example, to print or to have some text not displayed for a small screen, you can use Display:none. This is very simple, but sometimes for some people this is a bit useless, they can remove this

The form cannot be displayed in part until the entire table is downloaded and rendered.
Typically, the amount of CSS code is less than a clunky table.
All layout code can be saved to an external CSS file, only once and then cached in the user's browser, and the table layout must be saved in each HTML document and downloaded again each time the refresh is refreshed.
You can control the order in which CSS items are downloaded by using
qualitative change.
Next, look at the evolution of handheld devices:
The handheld device development process is the continuous optimization of the input/output mode, in this accumulation of quantitative changes to the ultimate change, that is, changed the traditional input/output mode, the introduction of physical and chemical sensors, mobile phones become more intelligent, able to perceive people's to

Background difference method to realize the challenge of moving object detection is: must adapt to the environment changes (such as the change of the illumination of the image color changes), camera jitter caused by the picture jitter (such as the handheld camera to take photos of the movement), images of dense objects (such as leaves or trunks, such as dense appearance of objects, Properly detected), it must be possible to correctly detect chan

find that there are some defects in this pattern:
Because each parent module maintains all of its submodules itself, the coupling between parent and child modules is too strong, and the parent module must couple all submodules
Because the modules cannot leapfrog directly between calls, the Submodule must pass the event up and down if the sub-module requires additional module assistance, which can affect system efficiency if the hierarchy
In itself this sentence is very good explanation, the function has two main characteristics, quoted from the Chen Xin translation of "javascript mode":
1. The function is the first class of objects:
Functions can be created dynamically at run time, and can also be created during program execution.
Functions can be assigned variables, they can be copied to other variables, can be extended, in addition, except for a few special cases, functions can also be deleted.
