Auto-generate LESS styles for sprite icons

阅读更多关于 Auto-generate LESS styles for sprite icons

问题 I have icon sprites image with each icon in a 20 by 20 pixel area. Each icon has several variants (black, colour, white small etc.). And have a significant amount of them. Instead of writing styles for each individual icon I'd rather just provide their names in my LESS file and let the processor generate styles for them. This is what I came up with but it doesn't seem to work. @icons: upvote,downvote,comment,new,notify,search,popup,eye,cross; @array: ~`(function(i){ return (i + "").replace(/[

Using LESS mixin to set variable multiple times but getting wrong results

阅读更多关于 Using LESS mixin to set variable multiple times but getting wrong results

问题 At the front, I started with less today... So any advice how to do that better is welcome! I have following .less file: .test(@target;@context) { @em: (@target / @context) * 1em; } .custom-field { position: relative; .test(30;16); padding-bottom: @em; .test(30;16); margin-bottom: @em; .test(320;16); max-width: @em; } I expect that padding-bottom and margin-bottom getting the value 1.875 and max-width: 20. But thats the output: .custom-field { position: relative; padding-bottom: 1.875em;

LESS strictImports

阅读更多关于 LESS strictImports

问题 I have a build that compiles several less files (all are actually imported into one master.less file). One of the options for the build is strictImports which suggests that it forces the evaluation of imports. Does anyone know if this have to do with operations in imported files, or am I completely missing the point? 回答1: The strictImports controls whether the compiler will allow an @import inside of either @media blocks or (a later addition) other selector blocks. See some of the comments

Netbeans 7.4 - exclude LESS partial source files from compiling to css

阅读更多关于 Netbeans 7.4 - exclude LESS partial source files from compiling to css

问题 This is mostly a nuisance problem (creating clutter in my css directory). I want to know if, in Netbeans 7.4 (or 8.0 beta?), there is any way to tag a LESS file to no be compiled on run/save. I have a library.less and vars.less file that are .mixins and @variables that get used site-wide in several other less files as includes but don't need to be compiled themselves as they produce effectively empty CSS. I'd like Netbeans OR lessc.cmd to ignore them if possible. Is it something that can be

上一次讲了如何在浏览器端解析less文件，这次是在cmd中使用npm中的less模块来解析详解如下首下我们去下载一个https://nodejs.org/en/ , 一路next之后，因为文件不大，就直接在C盘了当然我个人是不推荐在C盘的，你喜欢在哪个盘就哪个盘进入cmd 好，我们已经看到了node和npm的版本号了说明我们已经成功安装了如果没有看到，说明你需要在管理员权限下执行cmd 然后你需要创建两个文件夹在CMD中输入 npm config set prefix "C: \Program Files \nodejs \node_global" npm config set cache "C: \Program Files \nodejs \node_cache" 这样就应该正确了好下面，进入less中文网，我们看下怎么安装在安装这一项里面，我们可以看到，$符号就不用输了在cmd里面输入 npm install -g less，经过漫长的等待以后，恩，好了@_@ 如图所示，已经安装了下面要找到我们的lessc文件在哪个文件夹里面了来看C盘的nodeJS下的node_global文件夹里面找到了那我们就从CMD里面进入这个文件夹好，现在已经进入这个文件夹了下面就是一个转化语句了 lessc styles.less styles.css

LESS/SASS CSS opposite from minification/optimizations?

阅读更多关于 LESS/SASS CSS opposite from minification/optimizations?

问题 I wonder can I say that LESS/SASS CSS "pre-processors( I think they are called? )" is the opposite from optimizations like minification? I wonder if there will be any noticeable performance impact? or do you think easy of development is more important? I ask this because what LESS CSS generates is something like body #div1 #div2 p body #div1 #div2 p a:link, body #div1 #div2 p a:visited ... and I think it can really bloat up my CSS quite a bit. as you can see, such specificity is not required
