This is the assessment of CMT119 Computational Thinking. There are four pages, and each page has one topic. The homepage simply introduces the structure of the web pages. The first page is going to an introductory guide. A brief computer scientist biography will be shown on the second page. The third page will talk about a short reflection on the module. At the left-hand side of each page, a navigation bar is provided for selecting the page. All pages use the CSS grid to achieve the layout, and all pages are responsive to adapt to different resolutions of the screens on different devices.
