Different Size in CSS @page :first Result Whole @page in Same Size

Its about Print, and Print only. css: @page { size: A4 portrait; } @page :first{ size: 210mm 1000mm; } As CSS defined, should only first page with 1000mm height and rest pages are 297mm (A4) height. But in Chrome, from second page, looks like 297mm but all content is gone. Try it yourself, use Google Chrome, open http://fiddle.jshell.net/T4nnG/1/show/ and try print, see the preview, first page is right, and from second page, size is right, but content gone You can see more clearly by use "save as PDF", but if you choose a real printer, it will shrink first page, the bugs are same It may only

Python Scrapy 只会一遍又一遍地抓取相同的元素(Python Scrapy only scraping the same elements over and over again)

问题 我正在尝试学习 Scrapy,我正在 yelp 网站上学习这个 LINK 但是当 scrapy 运行时,它会一遍又一遍地抓取相同的电话、地址,而不是抓取不同的部分。 我使用的选择器是所有的“li”标签,属于页面的每个餐馆的特定类,每个LI标记包含我使用适当的选择器的每个餐厅信息,但Scape给了我的结果,重复形成2或3家餐馆。 出于某种原因,Scrapy 一遍又一遍地使用相同的部分,而当它们在 for 循环中完成时应该跳过它们。 这是代码 try: import scrapy from urlparse import urljoin except ImportError: print "\nERROR IMPORTING THE NESSASARY LIBRARIES\n" #scrapy.optional_features.remove('boto') url = raw_input('ENTER THE SITE URL : ') class YelpSpider(scrapy.Spider): name = 'yelp spider' start_urls = [url] def parse(self, response): SET_SELECTOR = '.regular-search-result' #Going over each li tags containg

bootstrap 3 navbar-top-fixed issue in android webview

I am working on a webapp which uses the latest bootstrap (3.1.1). I use this carousel sample app to build the main skeleton of the app. In each of the slides I will have my actual page content. In one of the slides I generate tables with a different width. The problem seems to appear only in Android Webview when the width of the table is bigger than the actual width of the device. The navbar gets white or invisible. I am not sure, but I can not see it. I am able to click on the navbar toggle(even though doesn't appear) and it does show the navbar items. Did anybody else had this problem before

使用 HTML 和 CSS 模仿 apple.com 的 globalsearch 输入字段(Mimic apple.com globalsearch input field with HTML and CSS)

问题 好的,所以如果您查看 http://www.marioplanet.com,您会看到我正在尝试为我的菜单栏模仿 apple.com 的设计,包括我的全局搜索栏。 现在,我正在尝试模仿 Apple 的全局搜索栏输入字段,尽可能接近,所以我需要一些帮助。 我希望该字段位于中间,我尝试使用maring: auto auto; 但这没有用.. 我也想使用 Apple 网站上的圆角技术,但我不知道该怎么做。 那是CSS3吗? 我还需要一个灰色的占位符字符串来读取Search ,但我认为我可以使用 JS 来实现它。 如果可以使用 HTML 或 CSS,请告诉我。 与输入字段左侧对齐的小聚光灯/放大镜图像很好,但不是必需的:) 好的,您可以查看该站点,但这里也是代码: 索引.htm: <div id="globalheader" class="apple"> <!--googleoff: all--> <ul id="globalnav"> <li id="gn-home"><a href="index.htm">Home</a></li> <li id="gn-catalog"><a href="catalog.asp">Shop!</a></li> <li id="gn-about"><a href="about.htm">About</a></li> <li id="gn

如何用伪元素制作一个弯曲的三角形语音气泡?(How to make a curved triangle speech bubble with pseudo-elements?)

问题 大家好,我正在尝试使用 CSS ::after伪元素制作一个弯曲的三角形语音气泡。 我创建了这样的DEMO : .test { position: relative; width: 430px; height: 175px; padding: 0px; background: #FFFFFF; -webkit-border-radius: 6px; -moz-border-radius: 6px; border-radius: 6px; } .test:after { content: ''; position: absolute; border-style: solid; border-width: 14px 14px 0; border-color: #FFFFFF transparent; display: block; width: 0; z-index: 1; bottom: -14px; left: 8px; } 我怎么喜欢这张照片? 回答1 您可以使用伪元素(及其诡计)来生成类似于此的内容: div { height: 200px; width: 350px; background: tomato; margin: 50px; position: relative; display: inline-block; } div:before { content: "

如果我允许用​​户添加 CSS,是否存在安全威胁?(Is there a security threat if I enable a user to add CSS?)

问题 让用户在(例如)社交网站中将自己的 CSS 规则添加到他的个人页面中是否不安全? 回答1 它不安全。 有多种方法可以将 JavaScript 嵌入到 CSS 中,这样它至少可以被某些浏览器执行。 谷歌“XSS CSS”并查看热门歌曲。 不要这样做,除非你愿意对 CSS 进行核心清理,并在清理不可避免地绕过并且用户的 cookie 受到损害时清理混乱。 回答2 允许他们以自由格式文本的形式输入 CSS(或上传文件)可能会导致安全问题。 给他们一个控制面板让他们自定义外观和感觉可能更安全(当然,有限制,可能无法构建一个让他们自定义一切的表单),并通过 CSS 实现自定义,同时存储他们的设置作为一组结构化数据库表中的值。 回答3 我想以前有人回答过这个问题。 历史教训:myspace 允许自定义 CSS 和脚本。 对于那些在 2003 年左右没有在网上闲逛的人来说,这是一个重大的安全威胁。 后来,作为卖点的大量用户生成的 CSS 成为平台的主要损害,因为许多更改和改进无法进行,因为他们有效地为他们的 CSS 钩子创建了一个公共 API。 所以让用户做 CSS 是一个非常非常糟糕的主意。

Fix full screen background image on Squarespace page

I'm having issues getting background images to display full screen (take up the whole background space) with a Squarespace page. My CSS was working but somehow it stopped working and now I have a gap on the bottom of the screen. The issues i've been having with Squarespace and how it sets up HTML for you, so recreating this issue really does not help. Instead, you can view the page at richiequake.com and use the password Help123 to access it. This issue happens in the Desktop version and Mobile version of the page. This is my CSS for Desktop: #collection-5de6d28545f1a7075b7a2741 #canvas{ max
