A.假設你的DIV總寬度是900px，我們可以這樣寫：

Q.為什麼IE對於margin的算法有些不同？

A.當我們針對div設定了浮動(float)屬性之後，IE瀏覽器就會將margin加倍計算。例如我們設定margin-left:5px;，IE會算成10px。解決的方法是在該浮動區塊加上「display:inline」即可解決這個問題。

Q.為什麼設定超連結的visited會失效？

A.超連結的樣式有一定的順序，如果你同時要設定visited(訪問過的連結)，或是active(作用中的連結)，必須要按照這個順序設定：a:link→a:visited→a:hover→a:active。我們不用死記順序，可以這麼記：love、hate

Q.如何在圖片上方放置flash？

A.有時候我們會看到有人的圖片上有flash的光圈特效，如果你要使用該特效，請將圖片設定為背景圖，然後在上方插入flash，記得要將flash設置為透明屬性：

Q.在火狐瀏覽器設定最小高度

A.一般對區塊設定高度(height)後，在火狐瀏覽器中如果輸入超過高度的文字，區塊不會被撐開。如果我們希望可以設定最小高度，同時又希望文字過多可以撐開區塊的話，可以將你的區塊改寫為：

The Restricted Access Document

The document “Restricted Information” is only available to user john with password orange and user sheri with password apple. The first time you click on “Restricted Information”, your web browser should prompt you for a user name and password. If it does not you may be using a web browser which is not HTTP authentication capable. 

Ingredients

NOTE: Please make sure you are setting this up in the directory that you want passwd protected. The .htpasswd file will end up in the wrong directory otherwise. For more infomation on how to use Unix, please check out our Unix Tutorial.

• The web document to be protected.Actually, access is restricted by directory so all files in the same directory will be protected. 
• The file .htaccess.This file should be in the directory which contains the documents to restrict access to. The contents of this file specify the name of the password file.For example if you were user jdoe with web documents in the local directory “/home/jdoe/public_html/goodstuff” that you wanted to restrict access to, your .htaccess might look like:

  AuthUserFile /home/jdoe/public_html/goodstuff/.htpasswd
AuthName jdoe_goodstuff
AuthType Basicrequire valid-user
Note that .htaccess will not work if there are extra spaces after AuthUserFile.

   

• The file .htpasswd.This file contains the passwords of the users.To create the .htpasswd file log in to this server using SSH, change directory to the directory you want to restrict access to, and type:

  htpasswd -c .htpasswd someuser

  for the first user (where someuser is the username). You will then be prompted twice for the user’s password. The -c option causes the .htpasswd file to be created. For each additional user type:

  htpasswd .htpasswd someuser

   

NOTE: There is no correspondence between the usernames and passwords used for accounts on this server and usernames and passwords in any specific .htpasswd file. A user doesn’t need to have an account on this system in order to be validated for access to files protected by HTTP-based authentication.

報道指出 , 雙方的討論仍然處於敏感階段 , 隨時都可能終止.

美聯社引述 Google發言人表示, 不會評論巿場傳言及揣測.

分析員普遍認為, 如果交易最終落實, 對兩家公司都有好處 . Google目前坐擁100億美元現金, 如果成功收購YouTube, Google在影像搜尋巿場就會一躍而成巿場領導; 另一方面, 隨著YouTube的流行程度增加 , Google亦能確保 YouTube的基建設施能應付巿場需求 .

Nielsen/NetRatings的資料顯示, 在七月份, YouTube網站流灠人次為3050萬 , 而Google Video只有930萬人次, Yahoo Video就有530萬人次.

此外 , YouTube用戶每日觀看超過 1億段影像短片.

今年初, 巿場有傳言指YouTube會成為主要媒體公司的收購目標, 行政總裁赫爾利當時表示, 公司不會放售, 日後更有可能會招股上巿
 

但是!!慘的是… FireFox竟然不支援這種屬性，於是剛剛查了FireFox的官網，查到下列解決的辦法
在embed中也加上wmode=”transparent”
ex: embed src=”images/xxx.swf” mce_src=”images/xxx.swf” wmode=”transparent” quality=”high” ……..
 

Main Headings

Hits represent the total number of requests made to the server during the given time period (month, day, hour etc..).

Files represent the total number of hits (requests) that actually resulted in something being sent back to the user. Not all hits will send data, such as 404-Not Found requests and requests for pages that are already in the browsers cache.

Tip: By looking at the difference between hits and files, you can get a rough indication of repeat visitors, as the greater the difference between the two, the more people are requesting pages they already have cached (have viewed already).

Sites is the number of unique IP addresses/hostnames that made requests to the server. Care should be taken when using this metric for anything other than that. Many users can appear to come from a single site, and they can also appear to come from many ip addresses so it should be used simply as a rough guage as to the number of visitors to your server.

Visits occur when some remote site makes a request for a page on your server for the first time. As long as the same site keeps making requests within a given timeout period, they will all be considered part of the same Visit. If the site makes a request to your server, and the length of time since the last request is greater than the specified timeout period (default is 30 minutes), a new Visit is started and counted, and the sequence repeats. Since only pages will trigger a visit, remotes sites that link to graphic and other non- page URLs will not be counted in the visit totals, reducing the number of false visits.

Pages are those URLs that would be considered the actual page being requested, and not all of the individual items that make it up (such as graphics and audio clips). Some people call this metric page views or page impressions, and defaults to any URL that has an extension of .htm, .html or .cgi.

A KByte (KB) is 1024 bytes (1 Kilobyte). Used to show the amount of data that was transfered between the server and the remote machine, based on the data found in the server log.

Referrers are those URLs that lead a user to your site or caused the browser to request something from your server. The vast majority of requests are made from your own URLs, since most HTML pages contain links to other objects such as graphics files. If one of your HTML pages contains links to 10 graphic images, then each request for the HTML page will produce 10 more hits with the referrer specified as the URL of your own HTML page.

Search Strings are obtained from examining the referrer string and looking for known patterns from various search engines. The search engines and the patterns to look for can be specified by the user within a configuration file. The default will catch most of the major ones.

Note: Only available if that information is contained in the server logs.

User Agents are a fancy name for browsers. Netscape, Opera, Konqueror, etc.. are all User Agents, and each reports itself in a unique way to your server. Keep in mind however, that many browsers allow the user to change it’s reported name, so you might see some obvious fake names in the listing.

Note: Only available if that information is contained in the server logs.

Entry/Exit pages are those pages that were the first requested in a visit (Entry), and the last requested (Exit). These pages are calculated using the Visits logic above. When a visit is first triggered, the requested page is counted as an Entry page, and whatever the last requested URL was, is counted as an Exit page.

Countries are determined based on the top level domain of the requesting site. This is somewhat questionable however, as there is no longer strong enforcement of domains as there was in the past. A .COM domain may reside in the US, or somewhere else. An .IL domain may actually be in Isreal, however it may also be located in the US or elsewhere. The most common domains seen are .COM (US Commercial), .NET (Network), .ORG (Non-profit Organization) and .EDU (Educational). A large percentage may also be shown as Unresolved/Unknown, as a fairly large percentage of dialup and other customer access points do not resolve to a name and are left as an IP address.

Response Codes are defined as part of the HTTP/1.1 protocol (RFC 2068; See Chapter 10). These codes are generated by the web server and indicate the completion status of each request made to it.
