HTML & CSS

 





HTML & CSS:

                CSS Stands for “Cascading Style Sheet”. It was introduced in late 1996.

            CSS saves a lot of work and time.

With CSS, you can control the color, font, the size of text, the spacing between elements,  what background images or background colors are to be used, different displays for different devices and screen sizes, how elements are positioned and laid out, and much more!

 It is used to control the layout of various

            Web pages all at once.

Types of CSS:

            There are three types of the style sheet

1.      Inline styling

2.      Internal styling

3.      External styling

Inline Styling:

                An inline CSS is used to apply a style to a single HTML element.

An inline CSS uses the "style" attribute of an HTML element.

 

Example:

                Following are some examples of inline CSS.

1.         <h1 style="color:red;">A Red Heading</h1>

2.         <p style="color:green;">A Green paragraph.</p>

Internal Styling:

               

An internal CSS is defined in the <head> section of an HTML page, within a <style> element. Used to apply a style for a single HTML page.

Example:

The following example sets the text color of ALL the <h1> elements (on that page) to “silver” and the text color of ALL the <p> elements to red. In addition, the page will be displayed with a "powderBlue"

<html>

<head>

<style>

body {background-color: powderblue;}

h1   {color: selver;}

p    {color: red;}

</style>

</head>

<body>

 

<h1>This is a heading</h1>

<p>This is a paragraph.</p>

 

</body>

</html>

External Styling:

            An external style sheet is defined in a separate file saved with “.css” extension.

            To use an external style sheet, add a link to it in the <head> section of each HTML page by using <link> tag.

It is useful when the style is applied to many web pages

Example:

           

 

<html>

<head>

                        <link rel=”stylesheet” type=”text/css” href=”mystyle.css”>

</head>

<body>

 

<h1>This is a heading</h1>

<p>This is a paragraph.</p>

 

</body>

</html>

 

The file must not contain any HTML code and must be saved with a .css extension.

The external style sheet can be written in any text editor.

 

The "styles.css" file looks like:

 

"styles.css":

 

body {

 

  background-color: silver;

}

h1 {

  color: red;

}

p {

  color: blue;

}

Computer Graphics and image processing Mathematical Background

 Computer Graphics and image processing Mathematical  Background Numerical Background  1.1 Introduction  The instructed material in this course draws upon a numerical foundation in direct polynomial math.  We momentarily update a portion of the fundamentals here, prior to starting the course material in Chapter 2.  1.2 Points, Vectors, and Notation  Quite a bit of Computer Graphics includes conversation of focuses in 2D or 3D. Normally we compose such  focuses as Cartesian Coordinates for example p = [x, y]  T or q = [x, y, z]  T  . Point organizes are  accordingly vector amounts, instead of a solitary number for example 3 which we call a scalar  amount. In these notes, we compose vectors in striking and underlined once. Grids are composed  in striking, twofold underlined.  The superscript [...]  T indicates rendering of a vector, so focuses p and q are segmented vectors  (organizes stacked on top of ea...

Basics of Automata Theory

 Basics of Automata Theory  What is Automata Theory?  Introduction Automata Theory is an energizing, hypothetical part of software engineering. It set up its foundations during the twentieth Century, as mathematicians started creating - both hypothetically and in a real sense - machines that imitated certain highlights of man, finishing estimations all the more rapidly and dependably. The word machine itself, firmly identified with "mechanization", signifies programmed measures doing the creation of explicit cycles. Essentially expressed, the automata hypothesis manages the rationale of calculation concerning straightforward machines, alluded to as automata. Through automata, PC researchers can see how machines figure works and tackle issues and all the more significantly, how it affects a capacity to be characterized as calculable or for an inquiry to be depicted as decidable.  Robots are unique models of machines that perform calculations on a contribution by trave...

An Introduction to Computer Graphics and its Applications

An Introduction to Computer Graphics and its Applications Introduction to Computer Graphics: Illustrations are characterized as any sketch or a drawing or an extraordinary organization that pictorially addresses some significant data. PC Graphics is utilized where a bunch of pictures should be controlled or the production of the picture as pixels and is drawn on the PC. PC Graphics can be utilized in advanced photography, film, entertainment, electronic contraptions, and any remaining center innovations which are required. It is an immense subject and territory in the field of software engineering. PC Graphics can be utilized in UI configuration, delivering, mathematical item, movement, and numerous more. In most territory, PC design is a contraction of CG. There are a few apparatuses utilized for the execution of Computer Graphics. The essential is the <graphics.h> header document in Turbo-C, Unity for cutting edge and even OpenGL can be utilized for its implementation. It was d...
