- 4. CASCADING STYLE SHEET (CSS) • Cascading style sheet are used to format the layout of Web pages. • They can be used to define text styles, table sizes, and other aspects of Web pages that previously could only be defined in a page’s HTML.
- 5. ADVANTAGES OF CSS • CSS simplifies design changes. • Separating content from design enables you to create different style sheet for different audiences and devices. • As you get advanced with CSS, you can even create multiple style sheets for the same Web page.
- 6. CSS SYNTAX A CSS rule set consist of a selectors and a declaration block. A CSS declaration always end with a semicolon, and a declaration groups are surrounded by curly braces. p {color: red; text-align: center;} p-Selector. {color: red; text-align: center;}-Declaration. Where color and text-align is property, and blue and center is value.
- 7. TYPES OF CSS STYLES There are three types of CSS. 1. Internal (Embedded) Styles. 2. Inline Styles. 3. External Styles.
- 8. INTERNAL STYLES • It holds the CSS code for the webpage in the head section of the particular file. • This makes it easy to apply styles like classes or id’s in order to reuse the code. • The downside of using an internal stylesheet is that changes to the internal stylesheet only effect the page the code is inserted into.
- 9. EXTERNAL STYLES • It is a .css file that you link your website to. • This makes it so that what ever you changes in the .css sheet, will effect every page in your website. • This prevents you from having to many code changes in each page. This is for “global” site changes.
- 10. INLINE STYLES • It is specific to the tag itself. • The inline style uses the “HTML” style attribute to style a specific tag. This is not recommend, as every CSS changes has to be made in every tag that has the inline style applied to it • .The inline style is good for one an individual CSS changes that you do not use repeatedly through the site.
- 11. CSS SELECTORS CSS selectors allow you to select and manipulate HTML elements. CSS selectors are used to find (or select) HTML elements based on their on id, class, type, attribute, and more. CSS selectors are .. 1. The element selector. 2. The id selector. 3. The class selector.

- 13. The id selector The id selectors uses the id attribute of an HTML elements to select a specific element. The id selectors is used if you want to select a single ,unique element.To select an element with a specific id,write a hash character ,followed by the id of the element. Example #para1 { text-align: center; color: red; }
- 14. The class selector Class selectors selects elements with a specific class attribute. To select elements with a specific class, write a period character, followed by the name of the class. Example .center { text-align: center; color: red; }
- 15. Example of CSS <html> <head> <style> #rcorners { Border-radius:25px; Padding:20px; Width:200px; Height:150px; } </style></head> <body> <table border=“1” id=“rcorners”cellpadding=“10”> <tr><th colspan=“5”>EMPLOYEE DETAILS</th></tr> <tr> <td>Name</td> <td>Salary</td> </tr> <tr><td>anu</td><td>10000</td ></tr> <tr><td>manu</td><td>10000</ td></tr> </body> </html>
