Use frameset to frame the window and build a simple background page. This blog is as a simple background management page of the actual combat drill.1 First, you need a page, using Give each The code is as follows (the file name is custom, I write frameset.html):2 We need to specify a different URL in three frames, we need to write several HTML files: head.html; menu.html;menu1.html;menu2.html;menu3.html;menu4.html; Main.htmlHead.html:Four options, ea

Fill in the background pattern and open the material 1 you can define the pattern and then fill it. Here you can pull the material directly in, and then move to the background layer above, as long as the copy and then docking can only effect as shown in Figure 6. If you want to need another pattern material, please click here to download Open the material 2, use the Magic wand to check out and copy in, correct the edge size and direction, and then

These two tips, do not write do not know, a write scare! Are seemingly simple, actually do up on the Meng, have to think carefully, can write right! All have the date operation of the program should be careful Oh! Let's say the second one: 2. Calculate the age accurately according to the date of birth! The so-called calculation of the exact age is: birthday is not a day to grow one year old! Everyone commonly used, the number of years counted as age

5.8. hexadecimal. 2 5.8.1 hexadecimal DescriptionIn hexadecimal notation, we will first ask: there are only 10 Arabic numerals in total: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, how can we express the concept of "every 16 to 1? The method is to use English letters (uppercase and lowercase)Can be): expression a, B, c, d, e, f 10 ~ 15. So if I tell you: this is a number: "17fca0", you can certainly guess it is a hex
