. Grid lines Grid lines have horizontal and vertical lines, and criss-cross lines cut the mesh container into the smallest unit 单元格 . Gridlines are numbered and numbered starting with the number 1. There are 6 horizontal lines and 6 longitudinal line. If you like, you can give the line a name, and a line can have multiple names.

sea, and an elephant was standing on the back of the turtle, and the land on which we lived was the elephant's spine. Of course, what supports the sea is another problem. They also don't know the answer to the question.This cosmic outlook of the ancients is the result of imagination. It is a poetic, beautiful and vivid worldview. Let's take a look at what people today think about the universe. The earth is a rotating sphere, human beings live on its surface, when we head upward, some people are

Link: Click to open linkThe main idea:There is a timer, consisting of a ball numbered from 1 to N, with three tracks, corresponding to 1 minutes, 5 minutes, and 1 hours respectively. These three tracks can be thought of as stacks, each minute out of the heap of a ball, a ball heap can be considered a queue, the capacity of three tracks is 4,11,11. The ball first enters the 1-minute orbit, and when the fifth ball enters, the ball of the one-minute trac

Small knowledge The week system originates from astronomy.The ancients according to the known movement of the Stars: day, month, fire, water, water, gold, Earth. Seven planets. MovementEvery 24 hours around its own axis for a week, causing the sky around the earth a week phenomenon.The Earth rotates around the sun every 365 and 1/4, a second to 30-kilometer, the fastest or 1000 times times faster (but with the high-speed rail, it is wrong). The train chases the Earth, just like a turtle c

The mascript usetts Institute of Technology often mails out its acceptance letters to be delivered to prospective students on Pi Day.[3] Some also celebrate PI approximation day in addition to Pi Day, which can fall on any of several dates: Limit L 26: The Earth has traveled two radians of its orbit by this day (Limit l 25th in leap years); thus

As the company's products to the WebKit kernel, in the writing of public CSS, do not want to use the plug-in simulation, the way online review of the next CSS3 scroll bar beautification.First of all, first on a pair.The (source http://zhangyaochun.iteye.com/blog/1743283) of the stolen map from the network.The following are the corresponding pseudo-classes:::-webkit-scrollbar {/*1*/}/* scroll bar Overall section, can generally set width */::-webkit-scrollbar-button{/*2 */}/* buttons at both ends

the future, such a game could be used to fully simulate all the details of the real world. People enter this game, just like entering another real world. Therefore, this game does not require human design of any plots and roles. Yes, this game is just like the Matrix system in the hacking empire.Can such a game be developed? As we already know, if we focus on all the details of the real world, we will not be able to see any reproducible state. Similarly, if the game simulates all the details of

Generate a div of an animated ball, and generate five balls, five to generate a certain number of balls to use as the operation, according to the speed of the ball animation, generally speaking five can also guarantee that there is enough ball number to run the animation The contents of the animation are the outer and inner layers, the outer layer controls the orbit and direction of the animated ball, and the inner layers control the running state

, and your phone are all running on the program. The importance of the program is needless.And we're not sure that the whole world is a god-designed Sims program. I always really feel that our whole world is a program. Understanding programming may be the key to understanding our world. Let me give you some examples of what science fiction or popular science articles might be in these examples, I can't remember.The electrons run around the nucleus in orbit
