1. CSS My favourite ICT lesson By Federico Boschi Cascading Style Sheets

2. WHAT IS IT? CSS is a language that defines layout of HTML documents (web pages). CSS controls the visual aspect of the web pages, such as: The position and the style of HTML elements; Backgrounds; Colours and images; Text styles; Tag styles. CSS

3. IMPORT IT IN A HTML PAGE There are three modes to import a CSS in a html page: Inline; Built-in (into the head); styles External (into the head).

4. BASIC STANDARD In a CSS code, to define the styles of the tags, we need to write: tag { properly: valore; … } For example: p { color: red; text-align: justify;

5. THE COLOR The properly ‘color’ allows you to assign a color to a tag. For example: h1 { color: purple; } or with the hexadecimal code: h1 { color: #800080; }

6. THE BACKGROUND To assign a background color to a tag, we use the properly ‘background-color’: body { background-color: yellow; } Instead to insert a picture as background: body { background-image: url(file.jpg); }

7. FORMATTING TEXT To formatting the text there are a lot of properly: font-family: Garamond; defines the type of font font-size: 1px; defines the size of the text font-style: italic; defines the style of the text (italic or normal) font-weight: bold; defines the thickness of the text (bold or normal) text-align: justify; defines the alignment of the text (justify or center or left or right) text-decoration: underline; defines the line of the text (underline or overline or none)

8. POSITION AND SIZE OF OBJECTS To define the position of a object we can use some properly: margin-left: 5px; margin-right: 5px; margin-top: 5px; margin-bottom: 5px; Instead to define the size of a object: width: 70px; height: 40px;
