HTML 5: Audio & Video tags Before HTML 5, there was no standard for showing videos on a web page. Before HTML 5, videos & audios could only be played with a plug-in (like flash). The HTML 5 , element specifies a standard way to embed a video in a web page. Your browser does not support the video tag. Your browser does not support the audio element.
CSS (Cascading Style Sheets) • Styles define HOW to display HTML elements, while HTML describes WHAT to display. • We can embed our CSS to HTML by several ways.
• A CSS rule set consists of a selector and a declaration block: • The selector points to the HTML element you want to style. • The declaration block contains one or more declarations separated by semicolons. • Each declaration includes a property name and a value, separated by a colon.
id and class The id selector uses the id attribute of an HTML tag to find the specific element. An id should be unique within a page, so you should use the id selector when you want to find a single, unique element. #en { text-align: center; color: red; } /*comment*/ The class selector finds elements with the specific class. The class selector uses the HTML class attribute. . center { text-align: center; color: red; }
p. center { text-align: center; color: red; }
Grouping Selectors To minimize the code, you can group selectors. h 1, h 2, p { text-align: center; color: red; }
