Topic 8: Web page design
- What is the difference between HTML and CSS?
- HTML (hypertext markup language) describes the structure and content of a page. CSS (cascading style sheets) describes how it looks: colours, fonts and layout.
- What are the head and body sections of an HTML page for?
- Head: information about the page that is not shown in the main window, such as the title and links to style sheets. Body: the content displayed in the browser.
- Which HTML elements are used for headings, paragraphs and lists?
- h1 to h6 for headings (most to least important), p for a paragraph, ul for an unordered list, ol for an ordered list and li for each list item.
- Which HTML elements create a hyperlink and an image, and which attributes do they need?
- a creates a link, with href giving the destination. img inserts an image, with src giving the file and alt giving a text description.
- Why should every image have alt text?
- It is displayed if the image does not load and is read out by screen readers for visually impaired users.
- What are the parts of a CSS rule?
- A selector, which says which elements to style, and a declaration block in curly brackets holding property: value pairs, each ending with a semicolon.
- What is the difference between a type selector and a class selector in CSS?
- Type selector (h1): styles every element of that type. Class selector (.price): styles any element with class="price". These are the two selector kinds named in the 9210 specification.
- Which CSS properties does the 9210 specification list?
- background-color, color, text-align, font-family, font-size, font-weight and font-style. A rule is written selector { property : value }.
- Where is CSS placed in 9210 exam questions?
- In an embedded style sheet: a style element inside the page. Exam questions only use embedded style sheets.
- Give three key differences between HTML5 and earlier versions of HTML
- Any three: supports facilities previously needing add-ons; better support for web applications through scripting and new APIs; easier graphics and multimedia with the svg, canvas, audio and video tags; new semantic elements such as header and article.
- Server-side vs client-side scripting
- Server-side scripts run on the web server to generate pages dynamically. Client-side scripts run in the browser to add extra functionality to a page.
