transparencyNote: Why use PNG32 instead of "Png8 alpha Transparent"? Because the PC side of the internet is mostly good, it is recommended to use a better PNG image, obviously PNG32 is the most suitable, of course, you can also use "Png8 alpha Transparent", But the quality under the HD monitor is inferior to PNG32. bg{Background:url (global.png?v=20130530) no-repeat;_background:url (global_png8.png?v=20130530) no-repeat;//ie6 using the background map}Scenarios for using IE filters:Compare consu
characters long. But the rules are a little strange and I can't find an exact rule. If I use two escape characters, the file name is shortened by 5 characters, but when I use a lot of escape characters, the file name ends up with only two characters shortened.Other browsers do not have this length limitation issue. As long as the system is able to process the file, it will be able to save the file successfully. I tested the next 250 character-length file names, and chrome prompted me to reduce

Although PHP provides us with a lot of functions, some things are not very convenient to deal with. For example, the date-time functions provided by PHP are limited. MySQL provides us with a number of such functions. Is it possible to use MySQL functions to handle PHP programs? The author has made the following attempts.
$data _time= "1998-12-31 23:59:59";
$c
$query _id=mysql_query ("Select Date_add (' $data _time ', INTERVAL 1 year)", $connect _id);
$data _time=mysql_result ($query _id,0);

Number of perceptual child elements
This is one of the most complex techniques I have ever seen, from this article, do not rely on JS implementation of the number of child elements to apply different styles.
For example, CSS like this:
. List Li:nth-last-child (n+4) ~ li,.list li:nth-last-child (n+4): first-child { color:red}
You can achieve this effect: if the number of LI elements in the. List is greater than or equal to 4, it is d
