(1) Cut the big image into 16 small images and use the src label of the img label
(2) There is only one large image, and then the background image of each element is cut and located using the background-position of css. In this way, 16 arrays [0, 0], [-, 0] are required. [-] ......

Last weekend, the Department organized a tour and went to Huashan, which was very nice.
Tianhuashan is located in the northern part of gushui town, Kuan Dian Manchu Autonomous County, in the Eastern Mountainous Area of Liaoning province. It is the southwestern region of Changbai Mountains, with an altitude of more than 1100 meters and a total area of 63 square kilometers. The natural beauty of Qifeng, strange rock, forest, ancient wood, cave gorge, youjian, waterfall, and xishui is shining brigh

Preface
In terms of transmission rate, 802.11n can increase the WLAN transmission rate from 54 Mbps currently provided by 802.11a and 802.11g to 600 Mbps or even up to Mbps. The mimo ofdm technology, which is applied in combination with MIMO (multi-input and multi-output) and OFDM (Orthogonal Frequency Division Multiplexing) technology, improves the quality of wireless transmission and greatly improves the transmission rate.
The existing 802.11n Wireless AP/routing devices are mainly M and M pro
1. Support LevelThe support degree represents the probability that the itemsets {x, y} appear in the total itemsets. The formula is:Support (X→Y) = P (x, y)/P (i) = P (x∪y)/p (i) = num (xuy)/num (i)Where I represents the total set of items. Num () indicates the number of itemsets2. Confidence level (Confidence)The confidence level indicates the probability of Y being rolled out by the association rule "X→y" in the case where prerequisite X occurs. That is, in the set of items containing x, the l

Recently, dedecms5.3 and dedecms5.5 encountered an incredible problem: when adding a column, the IE kernel browser cannot save the column content. After searching for the website for half a day, I couldn't find a solution. I found that the official search result of dedecms was "topic content" which could not be saved or modified. I opened the following two files in the Dede/templets directory.Catalog_add.htm is about 519 rowsCatalog_edit.htm: about 426 rowsPlace

the popularity of Apple devices, 5G wireless network cards are installed in the latest MBP/MBA/IPAD, so 5G users are also quite impressive. At the same time, in newer Windows laptops, dual-band wireless network adapters are also increasingly used. This test mainly verifies the specific performance of wireless transmission under 2G and 5g. The output conclusions serve as a reference for the future use of wireless devices. In this test, four devices are used:

/address Restriction
You can use the smtpd_client_restrictions parameter to restrict the host name or IP address of the client that initiates an SMTP connection to the Postfix. One or more parameter values can be specified, separated by commas. The restriction rules are executed in the query order, and the first rule that meets the conditions is executed. Available rules include:
Reject_unknown_client: if the client's IP address does not have PTR records in the DNS, the client's connection reque
parameter is not used by default.
The-t parameter specifies the table to be saved. By default, all tables are saved. The following shows the output of iptables-save without loading any rules.
