HTML Forms
Forms allow users to enter and submit information on a webpage.
You see forms everywhere:
• Login pages
• Registration pages
• Search boxes
• Contact forms
• Checkout pages
• Job applications
• Feedback forms
1. The <form> Element
A form is created using <form>.
<form>
...
</form>
Example:
<form>
<label>Name</label>
<input type="text">
<button>Submit</button>
</form>
2. <label>
<label> describes what an input field is for.
<label for="name">Name</label>
<input type="text" id="name">
The for value should match the input's id.
label
↓
for="name"
↓
id="name"
↓
input
This also improves accessibility and makes the form easier to use.
3. Text Input
The most common input is a text field.
<input type="text">
A better version:
<label for="name">Full Name</label>
<input type="text" id="name" name="name">
4. Email Input
<label for="email">Email</label>
<input type="email" id="email" name="email">
The email type allows browsers to provide appropriate input behavior and basic validation.
5. Password Input
<label for="password">Password</label>
<input type="password" id="password" name="password">
The entered characters are normally hidden.
6. Number Input
<label for="age">Age</label>
<input type="number" id="age" name="age">
This is useful when the expected value is numeric.
7. Submit Button
<button type="submit">Submit</button>
When placed inside a form, this submits the form by default.
You can also write:
<input type="submit" value="Submit">
However, <button> is generally more flexible.
8. Required Fields
The required attribute tells the browser that a value must be provided.
<input
type="email"
id="email"
name="email"
required>
The browser can prevent submission when the required field is empty.
9. Placeholder
placeholder provides a hint inside an input.
<input
type="text"
placeholder="Enter your name">
Important: a placeholder is not a replacement for a <label>.
10. Radio Buttons
Radio buttons allow the user to select one option from a group.
<p>Gender</p>
<label>
<input type="radio" name="gender" value="male">
Male
</label>
<label>
<input type="radio" name="gender" value="female">
Female
</label>
The same name groups the radio buttons together.
11. Checkboxes
Checkboxes allow users to select multiple options.
<label>
<input type="checkbox" name="skills" value="html">
HTML
</label>
<label>
<input type="checkbox" name="skills" value="css">
CSS
</label>
Unlike radio buttons, multiple checkboxes can be selected.
12. Textarea
Use <textarea> for longer text.
<label for="message">Message</label>
<textarea
id="message"
name="message"
rows="5"
cols="30">
</textarea> | 69 |

10. Tables vs Layout
Tables should be used for tabular data.
Good use:
Employee | Department | Salary
Not recommended:
Using tables to position
a website's navigation,
images and buttons.
Modern layouts should use CSS Flexbox and Grid instead.
🧠 Remember
<table> → Entire table
<tr> → Table row
<th> → Header cell
<td> → Data cell
<thead> → Header section
<tbody> → Main data section
<tfoot> → Footer/summary section
Key Takeaway
A semantic table usually follows this structure:
<table>
↓
<thead> → column headings
↓
<tbody> → actual data
↓
<tfoot> → totals/summary
HTML tables are primarily about representing relationships between rows and columns. CSS will later control how the table looks.

HTML Tables
Tables are used to display information in rows and columns.
For example, a website might use a table to display:
• Employee information
• Product details
• Exam results
• Prices
• Sales data
• Schedules
1. Basic Table Structure
A simple HTML table looks like this:
<table>
<tr>
<th>Name</th>
<th>Role</th>
</tr>
<tr>
<td>Rahul</td>
<td>Developer</td>
</tr>
<tr>
<td>Priya</td>
<td>Designer</td>
</tr>
</table>
The structure is:
<table>
↓
<tr> → Table Row
↓
<th> → Header Cell
<td> → Data Cell
2. <table>
The <table> element defines the entire table.
<table>
...
</table>
Everything belonging to the table goes inside it.
3. <tr> — Table Row
<tr> creates a row.
<tr>
<td>Rahul</td>
<td>Developer</td>
</tr>
Each <tr> represents one horizontal row.
4. <th> — Table Header
<th> represents a header cell.
<tr>
<th>Name</th>
<th>Age</th>
<th>City</th>
</tr>
Browsers typically display header cells in bold.
5. <td> — Table Data
<td> represents normal data.
<tr>
<td>Rahul</td>
<td>25</td>
<td>Pune</td>
</tr>
6. Understanding the Structure
Consider:
<table>
<tr>
<th>Name</th>
<th>Department</th>
</tr>
<tr>
<td>Amit</td>
<td>Finance</td>
</tr>
</table>
7. <thead>, <tbody> and <tfoot>
For larger or more structured tables, HTML provides sections.
<table>
<thead>
<tr>
<th>Product</th>
<th>Price</th>
</tr>
</thead>
<tbody>
<tr>
<td>Laptop</td>
<td>₹60,000</td>
</tr>
<tr>
<td>Phone</td>
<td>₹30,000</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>Total</td>
<td>₹90,000</td>
</tr>
</tfoot>
</table>
The structure becomes:
<table>
├── <thead>
│ └── Header rows
│
├── <tbody>
│ └── Main data rows
│
└── <tfoot>
└── Summary/footer rows
8. colspan
colspan allows a cell to span multiple columns.
<tr>
<td colspan="2">Total Sales</td>
</tr>
Here the cell occupies two columns.
9. rowspan
rowspan allows a cell to span multiple rows.
<tr>
<td rowspan="2">Finance</td>
<td>Rahul</td>
</tr>
<tr>
<td>Priya</td>
</tr> | 1 796 |

HTML Lists —
,
&
1.
Lists are used whenever information needs to be presented as a group of related items.
1. Unordered List
An unordered list displays items with bullets.
<ul>
<li>HTML</li>
<li>CSS</li>
<li>JavaScript</li>
</ul>
It produces:
• HTML
• CSS
• JavaScript
<ul> means unordered list.
2. List Item
Each item inside a list uses <li>.
<li>HTML</li>
Think of it as:
<ul> → List container
↓
<li> → Individual item
3. Ordered List
An ordered list displays items in a sequence, usually using numbers.
<ol>
<li>Learn HTML</li>
<li>Learn CSS</li>
<li>Learn JavaScript</li>
</ol>
It produces:
1. Learn HTML
2. Learn CSS
3. Learn JavaScript
<ol> means ordered list.
4. When to Use Which?
Use <ul> when order doesn't matter:
<ul>
<li>Apples</li>
<li>Bananas</li>
<li>Oranges</li>
</ul>
Use <ol> when order or sequence matters:
<ol>
<li>Create an account</li>
<li>Verify your email</li>
<li>Log in</li>
</ol>
5. Nested Lists
A list can contain another list.
<ul>
<li>
Frontend
<ul>
<li>HTML</li>
<li>CSS</li>
<li>JavaScript</li>
</ul>
</li>
<li>
Backend
<ul>
<li>Node.js</li>
<li>Express</li>
</ul>
</li>
</ul>
The structure becomes:
• Frontend
• HTML
• CSS
•
JavaScript
•
Backend
• Node.js
• Express
6. Lists in Navigation
Lists are commonly used to structure navigation menus.
<nav>
<ul>
<li><a href="index.html">Home</a></li>
<li><a href="about.html">About</a></li>
<li><a href="contact.html">Contact</a></li>
</ul>
</nav>
CSS can later transform this into a horizontal navigation bar.
7. Lists in Real Websites
Lists are useful for many things:
• Shopping items
• Features
• Navigation menus
• Steps
• Skills
• Categories
• Search results
• Product specifications
For example:
<h2>My Skills</h2>
<ul>
<li>HTML</li>
<li>CSS</li>
<li>JavaScript</li>
<li>React</li>
</ul>
8. Important Rule
<li> should normally be used as a child of a list such as <ul> or <ol>.
Good:
<ul>
<li>HTML</li>
<li>CSS</li>
</ul>
Not appropriate:
<li>HTML</li>
<li>CSS</li>
🧠 Remember
<ul> → Unordered list → Bullets
<ol> → Ordered list → Numbers/sequence
<li> → List item → Individual item
Key Takeaway
<ul>
↓
Unordered group
↓
<li> Item
<li> Item
<li> Item
and
<ol>
↓
Ordered group
↓
<li> Step 1
<li> Step 2
<li> Step 3 | 2 100 |

HTML Images — <img> Tag
Images make webpages more visual and engaging. HTML provides the <img> element to display images.
1. Adding an Image
<img src="photo.jpg" alt="A beautiful landscape">
Unlike elements such as <p>, <img> does not need a closing tag.
2. The src Attribute
src stands for source.
It tells the browser where the image is located.
<img src="images/profile.jpg" alt="Profile photo">
The browser follows the path:
HTML
↓
src="images/profile.jpg"
↓
images folder
↓
http://profile.jpg
↓
Display image
3. The alt Attribute
alt provides alternative text describing the image.
<img src="profile.jpg" alt="Profile photo">
It is important for accessibility and can also be displayed if the image cannot be loaded.
A good alt describes the actual image:
<img src="dog.jpg" alt="Golden retriever sitting in a park">
Avoid unnecessary descriptions such as:
alt="image"
4. Images Inside Folders
Suppose your project looks like:
my-website/
├── http://index.html
├── http://style.css
└── images/
├── http://logo.png
└── http://profile.jpg
You can write:
<img src="images/logo.png" alt="Company logo">
5. Image Dimensions
You can specify dimensions using width and height attributes:
<img
src="profile.jpg"
alt="Profile photo"
width="300"
height="300">
However, modern websites commonly use CSS to control presentation and responsive sizing.
6. Absolute vs Relative Image Paths
Relative path:
<img src="images/photo.jpg" alt="Photo">
This refers to a file within your project.
An external image can use a full URL:
<img
src="https://example.com/photo.jpg"
alt="Example photo">
For real projects, images are often hosted as part of your application or through an image/CDN service.
7. Images as Links
You can place an image inside an anchor element:
<a href="https://example.com">
<img src="logo.png" alt="Example website">
</a>
Now clicking the image follows the link.
8. Decorative Images
Not every image provides meaningful information.
For a purely decorative image, an empty alt is appropriate:
<img src="decorative-line.png" alt="">
This tells assistive technologies that the image can be ignored.
9. Common Image Formats
You will commonly encounter:
JPEG / JPG → Photos
PNG → Transparency and graphics
SVG → Logos and scalable graphics
WebP → Modern web images
AVIF → Modern, highly compressed images
GIF → Simple animations
The appropriate format depends on the type of image and performance requirements.

Key Takeaway
The basic image structure is:
<img src="image.jpg" alt="Description of image">
The two most important attributes to remember are:
src → image location
alt → meaningful alternative text
