[转]100% Table Height

Occasionally designers may want to center content in a web page and they want it centered both horizontally and vertically. The traditional method for doing that is to put the content into a table and to assign a values of 100% to the table's HEIGHT attribute and center to the ALIGN attribute. Recently, that approach has become more problematic.

You may have used this before and had it work but now, for some reason, new pages you create won't center vertically. You may be changing pages from standard HTML to XHTML and now tables don't respect the 100% HEIGHT attribute. Read on.

There are a few things you need to know here. There is not now, nor has there ever been a HEIGHT attribute for tables. Scour the HTML specifications and you will not find HEIGHT among the attributes for the table tag. The fact is, table height is invalid code. If you attempt to validate a page where you have assigned a height to a table, it will fail. Assigning a height to the table tag is not the answer. You can, however, legally assign a height using CSS.

Rendering Modes

But why, you ask, did it used to work and now it doesn't? Without going into a lot of specifics, the answer is that it has to do with the browser's rendering mode as determined by the document's DOCTYPE. You can read a lot more about that subject on Eric Meyer's companion site for his book Eric Meyer on CSS. The point is that browsers, rendering pages in quirks mode, expand tables to fill the 100% HEIGHT. Browsers rendering pages in standards compliance mode don't. That means that, if a page has a full and proper DOCTYPE, including the URI, or if it uses an XHTML DOCTYPE, the browser will render the page in standards compliance mode. If a page does not have a DOCTYPE, or if it has a partial DOCTYPE without the URI, the the browser will render the page in quirks mode. Newer web design software has begun inserting the full DOCTYPE in pages, so the pages get rendered in standards compliance mode.

[转]做网站的一些定律

1.250定律
  拉德认为:每一位顾客身后,大体有250名亲朋好友。如果您赢得了一位顾客的好感,就意味着赢得了250个人的好感;反之,如果你得罪了一名顾客,也就意味着得罪了250 名顾客。
  在你的网站访客中,一个访客可能可以带来一群访客,任何网站都有起步和发展的过程,这个过程中此定律尤其重要。

2.达维多定律
  达维多认为,一个企业要想在市场上总是占据主导地位,那么就要做到第一个开发出新产品,又第一个淘汰自己的老产品。
  国内网站跟风太严重,比如前段时间的格子网,乞讨网,博客网,一个成功了,大家一拥而上。但实际效果是,第一个出名的往往最成功,所以在网站的定位上,要动自己的脑筋,不是去捡人家剩下的客户。同理,买人家出售的数据来建站效果是很糟糕的。

3.木桶定律
  水桶定律是指,一只水桶能装多少水,完全取决于它最短的那块木板。这就是说任何一个组织都可能面临的一个共同问题,即构成组织的各个部分往往决定了整个组织的水平。
  注意审视自己的网站,是速度最糟糕?美工最糟糕?宣传最糟糕?你首先要做的,不是改进你最强的,而应该是你最薄弱的。

4.马太效应
  《新约》中有这样一个故事,一个国王远行前,交给三个仆人每人一锭银子,吩咐他们:“你们去做生意,等我回来时,再来见我。”国王回来时,第一个仆人说: “主人,你交给我们的一锭银子,我已赚了10锭。”于是国王奖励他10座城邑。第二个仆人报告说:“主人,你给我的一锭银子,我已赚了5锭。” 于是国王例奖励了他5座城邑。第三个仆人报告说:“主人,你给我的一锭银子,我一直包在手巾里存着,我怕丢失,一直没有拿出来。”于是国王命令将第三个仆人的一锭银子也赏给第一个仆人,并且说:“凡是少的,就连他所有的也要夺过来。凡是多的,还要给他,叫他多多益善。”这就是马太效应。
  在同类网站中,马太效应是很明显的。一个出名的社区,比一个新建的社区,更容易吸引到新客户。启示是,如果你无法把网站做大,那么你要做专。作专之后再做大就更容易。

Managing Hierarchical Data in MySQL

中文翻译:http://www.cnblogs.com/phaibin/archive/2009/06/09/1499687.html

下载:Joe Celko's.Trees and Hierarchies in SQL for Smarties.pdf

其它资源:http://www.itpub.net/thread-1233846-1-1.html

Introduction

Most users at one time or another have dealt with hierarchical data in a SQL database and no doubt learned that the management of hierarchical data is not what a relational database is intended for. The tables of a relational database are not hierarchical (like XML), but are simply a flat list. Hierarchical data has a parent-child relationship that is not naturally represented in a relational database table.
