替代样式表被认为是有害的（由我，暂时）

< link rel =" stylesheet" HREF ="巴兹"类型= QUOT;文本/ CSS" title =" Baz" media =" screen，projection" /> < link rel =" alternate stylesheet" HREF =" FOO"类型= QUOT;文本/ CSS" title =" Foo" media =" screen，projection" /> < link rel =" alternate stylesheet" HREF ="栏"类型= QUOT;文本/ CSS" title =" Bar" media =" screen，projection" /> 今天早上我删除了备用样式表，只留下了一个 基于cookie的样式表选择器。 为什么？ 仅仅因为所有主要CSS支持 浏览器[1]的当前行为是抢先下载*所有*链接样式表，包括交替显示。即使是Internet Explorer， 甚至没有提供切换样式表的机制，也表现出这种行为！在我的情况下，这会在初始[2]页面上增加35KB 加载。 确实有些浏览器[3]更进一步下载背景 图像在备用样式表中引用。 因此，在大多数浏览器实现默认样式表之前，我要去 回到基于cookie的样式方法。 < / rant> [1]在Internet Explorer 5+中注意到这一点， Mozilla 1.x，Opera 7.x，Safari 1.1和Konqueror 3.1，虽然它可能影响其他人。 [2] 10KB页面，5KB默认样式表。 [3]值得注意的是Konqueror，Safari。 - Toby A Inkster BSc（荣誉）ARCS 与我联系 - http://www.goddamn.co .uk / tobyink /？page = 132[Xposted, f''up to alt.html,comp.infosystems.www.authoring.stylesheets]For ages I have provided links to alternate stylesheets from my pages asper W3C recommendations:<link rel="stylesheet" href="baz" type="text/css" title="Baz"media="screen,projection" /><link rel="alternate stylesheet" href="foo" type="text/css" title="Foo"media="screen,projection" /><link rel="alternate stylesheet" href="bar" type="text/css" title="Bar"media="screen,projection" />This morning I removed the alternate stylesheets, leaving only acookie-based stylesheet selector.Why?Simply because the current behaviour of all major CSS-supportingbrowsers[1] is to preemptively download *all* linked stylesheets includingalternates when the page initially loads.

In my case, this adds an extra 35KB to the initial[2] pageload.Indeed some browsers[3] go even further and also download the backgroundimages referenced in alternate stylesheets.So until most browsers implement default style sheets sanely, I''m goingback to the cookie-based styling method.</rant>[1] Noticed this in Internet Explorer 5+, Mozilla 1.x, Opera 7.x, Safari1.1 and Konqueror 3.1, although it probably effects others.[2] 10KB page, 5KB default style sheet.[3] Notably Konqueror, Safari.--Toby A Inkster BSc (Hons) ARCSContact Me - http://www.goddamn.co.uk/tobyink/?page=132推荐答案 Toby A Inkster写道：Toby A Inkster wrote:这个时间我删除了备用样式表，只留下了一个基于cookie的样式表选择器。 为什么？ 只是因为所有主要CSS支持的当前行为替换。即使是Internet Explorer，它甚至不提供切换样式表的机制也表现出这种行为！ This morning I removed the alternate stylesheets, leaving only a cookie-based stylesheet selector.

But I think you could have a defaultpage in normal (X)HTML, with buttons or links to generate the same page withdifferent style sheets with server side help. That way, the spidershouldn''t miss any actual content.--cheers m Toby A Inkster< Us ****************** @ deadspam.com>在留言新闻中写道：< pa **************************** @ goddamn.co.uk> ...Toby A Inkster <Us******************@deadspam.com> wrote in message news:<pa****************************@goddamn.co.uk >...
