  2. Cascading Style Sheets • CSS stands for Cascading Style Sheets and is a simple styling language which allows attaching style to HTML elements. • CSS is a set of style definitions; styles that describe each HTML element. HTML used only as a formatting language, responsible for the basic layout of a page. CSS is used for design of pages. • popo

  3. Cascading Style Sheets • A CSS rule has two main parts: a selector, and one or more declarations: • The selector is normally the HTML element you want to style. • Each declaration consists of a property and a value. • A CSS declaration always ends with a semicolon, and declaration groups are surrounded by curly brackets: • p {color:red;text-align:center;} • OR • p • { • color:red; • text-align:center; • } • popo

  4. Cascading Style Sheets • <html> • <head> • <style> • Body{background-color:#b0c4de;} • </style> • </head> • <body> • <h1>My CSS web page!</h1> • <p>Hello world! This is example.</p> • </body> • </html> • popo

  5. Cascading Style Sheets • Grouping Selectors • Style to many selectors. • Just separate the selectors with a comma. • h1,h2,h3,h4,h5,h6 { color: blue } • popo

  6. Cascading Style Sheets • CSS Class • CSS classes allow to apply a style to a given class of an element. • Class is specified by including a period (.) before the selector name. • The syntax for declaring a Class selector is as follows: • .Class Name { property:value; ... } • For example, • .na { color:#0000FF;background-color:green; } • To apply this style to the HTML, using the following code: • <p class="na">This is a sample using a Class selector.</p> • popo

  7. Cascading Style Sheets • CSS ID • Allow to assign a unique identifier to an HTML element. • ID is specified by including a number sign (#) before the selector name. • The syntax for declaring an ID selector is as follows: • #[ID Name] { property:value; ... } • For example, • #popo { color:#FF00FF; } • To apply this style to the HTML, using the following code: • <p id=“popo">This is a sample using an ID selector.</p> • popo

  8. Cascading Style Sheets • Three Ways to Insert CSS • External style sheet • Internal style sheet • Inline style • popo

  9. Cascading Style Sheets • External Style Sheet • Used when the style is applied to many pages. • Each page must link to the style sheet using the <link> tag. • The <link> tag goes inside the head section: • <head> • <link rel="stylesheet" type="text/css" href="mystyle.css" /> • </head> • An external style sheet can be written in any text editor. • Style sheet should be saved with a .cssextension. • popo

  10. Cascading Style Sheets • Css file (check.css) • hr {color:brown;margin-left:100;} • p {margin-left:20px;color:red;font-size:20px;} • body {background-color:grey;} • Html file • <html><head> • <link rel="stylesheet" type="text/css" href="check.css" /> • </head> • <body> • <hr> • <p >This is a sample using an ID selector.</p> • </body></html> • popo

  11. Cascading Style Sheets • Internal Style Sheet • Used when a single document has a unique style. • Internal styles included in the head section of an HTML page, by using the <style> tag, like this: • <head><style type="text/css"> • hr {color:brown;margin-left:100;} • p {margin-left:20px;color:red;font-size:20px;} • body {background-color:grey;} • </style></head> • <body> • <hr> • <p >This is a sample using an ID selector.</p> • </body></html> • popo

  12. Cascading Style Sheets • Inline Styles • Style sheets by mixing content with presentation. • To use inline styles use the style attribute in the relevant tag. • The example shows how to change the color and the left margin of a paragraph: • <p style=“color:red;margin-left:320px;font-size:50px;“ >This is a paragraph.</p> • popo

  13. Cascading Style Sheets • CSS properties used for background effects: • popo

  14. Cascading Style Sheets • Background-attachment • The background-attachment property specifies whether a background stays fixed on the screen. • Possible values are "fixed" (background stays in the same place when scrolling) and • "scroll" (background moves with the rest of content when scrolling). • <HTML> <HEAD> • <style> • body {background-attachment: fixed; background-image: url("2.jpg"); background-repeat: no-repeat; } • </style> </HEAD> • <BODY> <center> • <table height=900 width=200 style="background-color=red"> • <tr><td style="font-size=20px;">asdf<tr><td style="font-size=20px;">asdf • </center></table> </BODY> • </HTML> • popo

  15. Cascading Style Sheets • Background-color • The background-color property specifies the color of the background. • popo

  16. Cascading Style Sheets • Background-position • The background-position property specifies the position of the background. • Two percentage values: The first value indicates the horizontal percentage, and the second value indicates the vertical percentage. • <HTML> <HEAD> • <style> • body { background-image: url("2.jpg"); background-repeat: no-repeat; • background-position: 10% 20%; } • </style> • </HEAD> • <BODY> • </BODY> • </HTML> • popo

  17. Cascading Style Sheets • Background-repeat • The background-repeat property specifies whether a background image repeats itself. • The default is "repeat", which means repeating the image in both the x- and y- directions. • You can also specify no-repeat. • <HTML> <HEAD> • <style> • body { background-image: url("2.jpg"); background-repeat: no-repeat;} • </style> • </HEAD> <BODY> • </BODY></HTML> • popo

  18. Cascading Style Sheets • Text Color • This text is styled with some of the text formatting properties. • The text-align, text-transform, and color, aligned, and the space between characters is specified. • <h1 style="background-color:red;color:blue;">popo • popo
