本課程主要教授採用Bootstrap框架於網站前端介面設計。Bootstrap是一組用於網站和網路應用程式開發的開源前端（所謂「前端」，指的是展現給終端使用者的介面。與之對應的「後端」是在伺服器上面執行的程式碼）框架，包括HTML、CSS及JavaScript的框架，提供字體排印、表單、按鈕、導航及其他各種元件及Javascript擴充套件，旨在使動態網頁和Web應用的開發更加容易。

Bootstrap is an open source toolkit for developing with HTML, CSS, and JS. Quickly prototype your ideas or build your entire app with our Sass variables and mixins, responsive grid system, extensive prebuilt components, and powerful plugins built on jQuery.
Bootstrap has become a very popular tool in front-end projects over the years. The framework's ease-of-use along with its cross-browser compatibility, support for mobile user interfaces, and responsive web design capabilities, make it an essential building block for any modern web application. The course will enable you to rapidly build elegant, powerful, and responsive interfaces for professional-level web pages using Bootstrap 4.
This course is of three main parts as follows,
(1) The first is the style sheet, which contains some basic CSS for almost every HTML.
(2) The second part is the components. They can be reused by just copying and pasting code.
(3) The last part is the JavaScript plugin, which includes some very common additional elements that cannot be found elsewhere.
