Sass的使用

╄→гoц情女王★ 提交于 2020-12-16 18:42:42
Sass是一种CSS预处理语言。 首先要了解什么是CSS预处理器? CSS预处理语言是一种新的专门的编程语言,编译后形成正常的css文件,为css增加一些编程特性,无需考虑浏览器的兼容性(完全兼容css3),让css更加简洁、适应性更强,可读性更佳,更易于代码的维护等诸多好处。 CSS预处理语言有Scss(Sass) 和Less、Postcss。 那么Scss和Sass有什么区别呢? Sass 有两种语法规则(syntaxes),目前新的语法规则(从 Sass 3开始)被称为 “SCSS”,它是css3语法的的拓展级,就是说每一个语法正确的CSS3文件也是合法的SCSS文件,SCSS文件使用.scss作为拓展名。第二种语法别称为缩进语法(或者 Sass),它受到了Haml的简洁精炼的启发,它是为了人们可以用和css相近的但是更精简的方式来书写css而诞生的。它没有括号、分号,它使用行缩进的方式来指定css 块,虽然sass不是最原始的语法,但是缩进语法将继续被支持,在缩进语法的文件以.sass为拓展名。 特性概览: CSS书写代码规模较大的Web应用时,容易造成选择器、层叠的复杂度过高,因此推荐通过Sass预处理器进行CSS的开发,Sass提供的变量、嵌套、混合、继承等特性,让CSS的书写更加有趣与程式化。 Scss的使用语法: ·注释: 注释分为三种:/* */css中显示,/

Is it possible to generate plain-old XML using Haml?

故事扮演 提交于 2020-05-10 04:25:55
问题 I've been working on a piece of software where I need to generate a custom XML file to send back to a client application. The current solutions on Ruby/Rails world for generating XML files are slow, at best. Using builder or event Nokogiri, while have a nice syntax and are maintainable solutions, they consume too much time and processing. I definetly could go to ERB, which provides a good speed at the expense of building the whole XML by hand. HAML is a great tool, have a nice and straight

asp.net 视图引擎归类

心已入冬 提交于 2020-03-12 05:17:54
1. ASPX View Engine 第一个也是我们最熟悉的---aspx,相信做过WebForm开发对Aspx都比较了解: 小示例: <%@ Control Inherits="System.Web.Mvc.ViewPage<IEnumerable<Product>>" %> <% if(model.Any()) { %> <ul> <% foreach(var p in model){%> <li><%=p.Name%></li> <%}%> </ul> <%}else{%> <p>No products available</p> <%}%> 设计目标: 一个用于呈现Web Froms页面的输出的视图引擎。 优点: •与ASP.NET MVC紧密集成 •对于以往ASP.NET开发人员有更好体验 •智能感应 •能选择其它语言的 CodeDom provider (例如: C#, VB.NET, F#, Boo, Nemerle) •立即编译或预编译的views 缺点: •在Asp.net MVC中容易与经典的Asp.net模式混淆起来,并且Asp.net MVC已不再支持它们。 (例如: ViewState PostBack) •能有助于反模式的"标签团" •智能感应强迫样式总是不在内联的代码块。 •设计简单模板时会凌乱。 2.

如何在另一个div内对齐3个div(左/中/右)?

我只是一个虾纸丫 提交于 2020-02-26 13:20:36
我想在容器div中对齐3个div,如下所示: [[LEFT] [CENTER] [RIGHT]] 容器div的宽度为100%(未设置宽度),调整容器大小后,居中div应该保持居中。 所以我设置: #container{width:100%;} #left{float:left;width:100px;} #right{float:right;width:100px;} #center{margin:0 auto;width:100px;} 但它变成: [[LEFT] [CENTER] ] [RIGHT] 有小费吗? #1楼 如果您不想更改HTML结构,也可以通过添加 text-align: center; 包装器元素和 display: inline-block; 到居中元素。 #container { width:100%; text-align:center; } #left { float:left; width:100px; } #center { display: inline-block; margin:0 auto; width:100px; } #right { float:right; width:100px; } 现场演示: http : //jsfiddle.net/CH9K8/ #2楼 这是当我以 图像 为中心元素时必须对接受的答案进行的更改:

Postgres error with Sinatra/Haml/DataMapper on Heroku

问题 I'm trying to move a simple Sinatra app over to Heroku. Migration of the Ruby app code and existing MySQL database using Taps went smoothly, but I'm getting the following Postgres error: PostgresError - ERROR: operator does not exist: text = integer LINE 1: ...d_at", "post_id" FROM "comments" WHERE ("post_id" IN (4, 17,... ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. It's evident that the problem is related to a type mismatch in

Conditionally use a content_for wrapper in haml

非 Y 不嫁゛ 提交于 2020-01-17 03:55:53
问题 I am trying to find a more DRY way to do the following: - if request.xhr? :javascript {my javascript} - else = content_for :scripts do :javascript {my javascript} I reuse this pattern in many haml files, so I am wondering what is the best way to abstract out the conditional logic. Ideally, I'd like to achieve something like the following in my haml files: optional_content_for :scripts do :javascript {my javascript} Thanks! 回答1: This seems to solve my need, in case anyone else has the same
