商品描述

Practical, hands-on recipes to write more efficient CSS, with the help of the LESS CSS Preprocessor library

Overview

  • Learn something new in an Instant! A short, fast, focused guide delivering immediate results.
  • Use mixins, functions, and variables to dynamically auto-generate styles, based on minimal existing values.
  • Use the power of LESS to produce style sheets dynamically, or incorporate precompiled versions into your code.
  • Learn how to use existing mixin libraries, or to create your own that you can reuse in future projects

In Detail

CSS styling has been a key part of developing for the Internet since the early 1990s, but unlike JavaScript, has suffered from the inability to produce dynamic styles using functions, operators, and variables. LESS brings the power of all three and more to your CSS, allowing you to engage a more efficient, modular style of working, and making it easier to maintain your CSS styling in your projects.

Instant LESS CSS Preprocessor How-To is a practical, hands-on guide that provides you with a number of clear step-by-step exercises to help you take advantage of the power of LESS, and give you a good grounding in writing and compiling CSS style sheets using the LESS Preprocessor language.

This book looks at how you can incorporate LESS into your web pages, and either produce style sheets dynamically, or pre-compile them before including the final article into your site’s pages.

You will also learn how you can use the power of mixins, functions, and variables to help produce style sheets, and reduce the amount of code you need to write in your style sheets. We will also take a look at how you can incorporate a more modular style to your development workflow, which will help with making style sheets more manageable and easier to update in the future. We will also take a look at how you can build up libraries of reusable code that you can incorporate into your future projects.

You will learn everything you need to know to start using LESS to help produce more efficient style sheets in your site’s pages, and adopt a more modular development workflow, which will make it easier to maintain your sites in the future.

What you will learn from this book

  • Install and use LESS into your site.
  • Produce dynamic style sheets, or precompiling and including the final articles into your site’s pages.

詳細內容
CSS 樣式自 1990 年代初期以來一直是網際網路開發的關鍵部分，但與 JavaScript 不同，CSS 無法使用函數、運算符和變數來生成動態樣式。LESS 將這三者及更多功能帶入您的 CSS，讓您能夠採用更有效率的模組化工作方式，並使您在項目中更容易維護 CSS 樣式。
