cly — Wed, 21 Sep 2016 17:08:30 +0800

各位大神在使用 pdfkit 生成 pdf 有遇到标点符号在行首的问题？如何解决！！试了各种 css 换行样式，不起作用，望各位大神指定迷津！！！我用的 gem 包！！！

.t4 { word-break:normal; word-wrap:break-word; text-justify:inter-ideograph; hyphenate:auto; font-family:FangSong; font-size:16pt; line-height:24pt; }

求教各位大神，看源代码和 gem 源码时如何抓住重点？

学习 ROR 将近 10 个月，开始看些开源源码和 gem 源码，但是总是看着看着想睡觉，看 readme 看一遍还是记不住，还需要照着敲，是自己目的性不强吗？跪求各位大神指点，如何在看源代码和 gem 源码时抓住重点？如果方便，请传教一些经验。还有就是想请教一下 railscasts-china 为什么访问不了了？谢谢！！！

报错了说：wrong number of arguments (1 for 2) ，找了好久没搞定，求大神指点迷津，谢谢
