This document discusses HTML forms, including:
- HTML forms allow users to enter and submit data through text boxes, buttons, checkboxes, radio buttons, and other controls.
- Forms are defined using <form> tags which specify an action and method for submitting data.
- Common form controls include text fields, passwords, checkboxes, radio buttons, buttons, textareas, and select menus.
- Accessible forms should use <label> tags, <fieldset> and <legend> elements to organize groups of controls.
- CSS can style forms and individual controls using properties like :focus and outline.
- Form layout can be controlled through <br>, tables, or CSS float and clear properties.
This slide guides through the differences of the Span and Div tags in HTML.

What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.

Here I am mentioning basic elements , attributes and tags of HTML with styling them
JavaScript Events:
HTML events are "things" that happen to HTML elements. When JavaScript is used in HTML pages, JavaScript can "react" on these events.
What can JavaScript Do?
Event handlers can be used to handle, and verify, user input, user actions, and browser actions:
Things that should be done every time a page loads
Things that should be done when the page is closed
Action that should be performed when a user clicks a button
Content that should be verified when a user inputs data

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

3. HTML Forms
HTML Forms are a common and important part of
the web.
Registration / login systems
Search facilities
HTML can be used to build forms.
Define the text boxes, buttons, checkbox, radio
buttons, etc.
HTML has no power to process the data entered
into a Form.
The browser passes the data to scripts on the web
server.
e.g. PHP, ASP.NET, Ruby
4. The Structure of Forms
All HTML forms are constructed using the <form>
element.
Identifies the start and end of an HTML form
5. The Structure of Forms
The action attribute specifies the URL of the script
to which the data will be sent.
It is a required attribute
The method attribute specifies how the data will
be sent.
The values can be get or post.
We can nest most elements inside the <form>
element, e.g. <p>,<div>, <table>.
6. Form Controls
We can create button
using <input> tag or
<button> tag. What is the
difference?
7. Form Controls
Form controls are the elements like the text boxes
and buttons used to gather data from the user.
Most form controls are created using the <input/>
element.
Empty element
The type attribute is used to specify the type of
control.
The name and id attribute is used by the script that
receives the data.
Syntax :
9. Form Controls – Text Fields
A value of ‘text’ for the type attribute specifies a text field.
The size attribute is used to define the visible size of the
text field.
The maxlength attribute is used to limit the number of
characters that can be entered.
The value attribute can be used to specify a default value
for the text field.
10. Form Controls - Password
A value of ‘password’ for the type attribute creates
a password field.
The characters entered will be replaced with
asterisk or bullet characters.
11. Form Controls – Checkboxes
Checkboxes allow users to select multiple options
from a list.
A value of checkbox for the type element specifies
a checkbox.
The checked attribute can be used to make the box
checked when the page loads.
The value attribute is used to associate a piece of
data with the checkbox.
13. Form Controls – Radio Buttons
Radio buttons allow users to select a single
option from a group.
Selecting one deselects all the others
To work together, all the radio buttons must
have the same value for the name attribute.
The checked attribute allows the radio
button to be selected.
14. Form Controls – Buttons
A value of submit for the type element specifies
a submit button.
The submit button submits the form and sends
the contents of to the URL specified in the
action attribute.
The value attribute can be used to change the
default text on the button
15. Form Controls – Buttons
A value of reset for the type element specifies a reset
button.
The reset button sets all controls back to their default
values.
Reset buttons are rarely used.
A value of button for the type element specifies a
normal button.
The normal button does nothing by default. We put
JavaScript code in such button.
16. Form Controls – Multiline Text
Field
The <textarea> element is used to create a
multiline text field.
The cols and rows attributes specify the size
of the text area.
A default value can be added as content in the
<textarea> element.
17. Form Controls – Select Menus
The <select> element is structured like a
list
The <option> element defines each item in the list.
Again a value can be associated with the item.
18. Form Controls – Select Menus
By default, the select menu works as a drop down
list.
We can add a size attribute to make it a scrolling menu.
19. Accessible Forms – The <label>
Element
The <label> element is used to associate a text
description with a form control.
The form control needs an id attribute.
The for attribute of the label element links the label to
the control.
Clicking on the label automatically places focus on
the form element.
All forms should use label elements.
21. Accessible Forms – The <fieldset>
and <legend> Elements
The <fieldset> element is used to group related
form controls together.
The <legend> element is used to give this
group a title.
Browsers provide default styling for the
<fieldset> element.
22. Accessible Forms – The <fieldset>
and <legend> Elements
Browsers render the <fieldset> as a box
containing the form controls that are part of the
<fieldset>.
Screen readers will read the <legend> content
before the each <label> element.
E.g. Contact Details Email
23. Accessible Forms
We have the same disadvantages
discussed previously.
Browser support
How does the user know the access key?
Tab order breaking conventional flow
24. Form Controls and Valid Documents
The <label>, <input/>, <textarea> and <select>
elements are all inline elements.
Need to be nested inside a block level element for the page
to be valid.
Form controls must be nested inside a <form>
element.
26. CSS and Forms
The :focus pseudo class specifies a style for
when the form control is being focused.
The outline property is commonly used to
highlight the form control.
27. CSS and Form – Attribute
Selectors
We can use an attribute selector to target
specific types of form control.
In this example, only form controls with a type
attribute of text will be affected by the rule.
29. Form Layout
By default, browsers apply little styling to form.
Possible approaches
1. Use <br/> elements
2. Use an HTML table
3. Use the CSS property
30. Form Layout – Using <br/>
Elements
<br/> elements can be used to place
different elements on different lines.
Limited control
Adding presentation information through HTML!
31. Form Layout – Using Tables
A simple table can be used to control form layout
33. Form Layout – Using CSS
We can use the float
property to make form
controls wrap onto the
same lines.
The clear property
makes the labels start
new lines.
34. Forms and Mobile Devices
‘free text’ input is difficult for many mobile
devices.
Mobile devices often have input limitations.
Use controls that do not require the user to type.
Tab order can help users select controls.
