What is LaTeX?
• LaTeX is pronounced “lay-tech” or “lah-tech,”
not “la-teks.”

What is LaTeX?
• LaTeX is a document markup language used to
create documents in TeX.
• LATEX is the standard mathematical
typesetting program

• A computer language that consists of easily
understood keywords, names, or tags that
help format the overall view of a page and the
data it contains.
• Some examples of a markup
language are HTML and XML.
Typesetting can be defined as the process
of preparing and arranging text and
images for printing

Latex was created by the American computer scientist named
Leslie Lamport in 1983

Why Use LaTeX?
• Mathematical symbols and equations are easily integrated.
• Even complex structures such as footnotes, references, table
of contents, and bibliographies can be generated easily.
• Creates more beautiful documents.
• Portable, compatible, flexible, and cheap (or free)!

Markup versus WYSIWYG
To someone familiar with MS Word /Open Office Writer ….Latex is that you do not
interact with a graphical user interface (GUI), and you do not immediately see how
your document will be typeset.
Consider a typical WYSIWYG ("what you see is what you get") word processor, such
as Open Office Writer, shown in the screenshot below:

xlabel={ Students Name},
symbolic x coords={Tom, Jack, Hary, Liza, Henry}, % these are the specification of
coordinates on the x-axis.
xtick=data,
nodes near coords, % this command is used to mention the y-axis points on the top
of the particular bar.
nodes near coords align={vertical},

addplot coordinates {(Tom,50) (Jack,90) (Hary,70) (Liza,80) (Henry,60) };

Three Ways to Insert CSS
•External CSS
•Internal CSS
•Inline CSS

Inline CSS
<!DOCTYPE html>
<html>
<body>
<h1 style="color:blue;text-align:center;">This
is a heading</h1>
<p style="color:red;">This is a paragraph.</p>
</body>
</html>
An inline style may be used to apply a unique style for a
single element.

Internal CSS
<!DOCTYPE html>
<html>
<head>
<style>
body {
background-color: blue;
}
h1 {
color: maroon;
}
</style>
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
An internal style sheet may be used if
one single HTML page

External CSS
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="my
style.css">
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
mystyle.css
body {
background-
color: lightblue;
}
h1 {
color: navy;
margin-left: 20px;
}
With an external style sheet, you can change the look of an entire
website by changing just one file!
Each HTML page must include a reference to the external style sheet file
inside the <link> element, inside the head section.
