CSS stands for cascading
style sheets Styles define how to display HTML elements Styles are normally
stored in Style Sheets Styles were added to HTML 4.0 to solve a problem
External Style Sheets can save you a lot of work External Style Sheets are
stored in CSS files Multiple style definitions will cascade into one.
Style
sheets are a very powerful tool for the Web site developer. They give you the
chance to be completely consistent with the look and feel of your pages, while
giving you much more control over the layout and design than straight HTML ever
did.
Types of CSS: There are three type Style sheets
a.
Inline Styles
b.
Internal Style Sheet
c.
External Style Sheet
Inline Styles: An inline style loses many of the
advantages of style sheets by mixing content with presentation. Use this method
sparingly, such as when a style is to be applied to a single occurrence of an
element.
For Example:
<p style="color: red; margin-left: 20px">
This is a paragraph
</p>
Internal Style Sheet: An internal
style sheet should be used when a single document has a unique style. You
define internal styles in the head section by using the <style> tag, like
this:
<head>
<style type="text/css">
hr {color: green}
p {margin-left:
20px}
body {background-image:
url ("images/kushtiwari.gif")}
</style>
</head>
The browser will now read the style definitions, and format the document according to it.
External Style Sheet: An external style sheet is ideal when the
style is applied to many pages. With an external style sheet, you can change
the look of an entire Web site by changing one file. 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>
Other CSS Questions
Question: Style Sheets Can Save a Lot of Work
Answer: Enforcing data integrity ensures the quality of the data in the database. For example, if an employee is entered with an employee_id value of 123, the database should not allow another employee to have an ID with the same value. If you have an employee_rating column intended to have values ranging from 1 to 5, the database should not accept a value of 6. If the table has a dept_id column that stores the department number for the employee, the database should allow only values that are valid for the department numbers in the company. Two important steps in planning tables are to identify valid values for a column and to decide how to enforce the integrity of the data in the column. Data integrity falls into these categories.
