Web Development

It provides a temporary hint. Remember: label → Identifies the field placeholder → Gives an example/hint A placeholder should not normally replace a proper label. 14. readonly

<input
    type="text"
    value="Customer ID: 1024"
    readonly>

The user can generally view the value but cannot edit it through the input. 15. disabled

<input
    type="text"
    value="Not available"
    disabled>

A disabled control cannot normally be interacted with or submitted as a successful form control. 16. maxlength Limits the number of characters.

<input
    type="text"
    name="username"
    maxlength="20">

17. minlength Specifies a minimum number of characters.

<input
    type="password"
    name="password"
    minlength="8">

18. autocomplete Helps the browser provide previously stored information.

<input
    type="email"
    name="email"
    autocomplete="email">

This can make forms faster and easier to use. 19. Form Attributes The <form> element itself has important attributes. For example:

<form action="/register" method="post">
    ...
</form>

action specifies where the form data should be sent. method specifies how the data should be submitted. Common methods include: GET POST We'll study HTTP methods and form submission more deeply when we reach backend development. 20. Putting It Together

<form action="/register" method="post">

    <label for="name">Full Name</label>
    <input
        type="text"
        id="name"
        name="name"
        required
        autocomplete="name">

    <label for="email">Email</label>
    <input
        type="email"
        id="email"
        name="email"
        required
        autocomplete="email">

    <label for="password">Password</label>
    <input
        type="password"
        id="password"
        name="password"
        minlength="8"
        required>

    <button type="submit">Create Account</button>

</form>

🧠 Remember type → What kind of input? name → Field's submission name id → Identifies the element value → Input's value placeholder → Hint required → Must be provided disabled → User can't interact normally readonly → User can't edit minlength → Minimum characters maxlength → Maximum characters Double Tap ❤️ For More ----- 1.66 ₽ · /balance_help

🌐 Web Development Roadmap — Part 21 HTML Input Types & Form Attributes In the previous lesson, you learned how to create forms. Now let's understand the different types of inputs and the attributes that make forms more useful. 1. Text Input

<input type="text" name="username">

Used for short text such as: • Name • Username • City • Job title 2. Email Input

<input type="email" name="email">

Used for email addresses.

<label for="email">Email</label>
<input type="email" id="email" name="email" required>

The browser can perform basic validation when the form is submitted. 3. Password Input

<input type="password" name="password">

Characters are normally hidden while the user types. Commonly used for: • Passwords • PIN-like fields • Secret values 4. Number Input

<input type="number" name="age">

Useful when the expected value is numeric. You can also specify limits:

<input
    type="number"
    name="age"
    min="18"
    max="100">

5. Date Input

<input type="date" name="birthdate">

Modern browsers can provide a date-selection interface. 6. File Input

<input type="file" name="resume">

Allows the user to select a file from their device. For example:

<label for="resume">Upload Resume</label>
<input type="file" id="resume" name="resume">

7. Checkbox

<input type="checkbox" name="terms">

Used when the user can select or deselect an option. Example:

<label>
    <input type="checkbox" name="terms" required>
    I agree to the terms and conditions
</label>

8. Radio Button Radio buttons are useful when the user should choose one option from a group.

<label>
    <input type="radio" name="experience" value="beginner">
    Beginner
</label>

<label>
    <input type="radio" name="experience" value="advanced">
    Advanced
</label>

The same name groups the options. 9. Search Input

<input type="search" name="query">

Designed specifically for search fields. Example:

<label for="search">Search</label>
<input type="search" id="search" name="query">

10. URL Input

<input type="url" name="website">

Used when the user needs to enter a website URL.

<input
    type="url"
    name="portfolio"
    placeholder="https://example.com">

11. name Attribute The name attribute identifies the field when form data is submitted.

<input type="text" name="username">

Think of it as the field's data key: name = username value = Rahul The backend can receive something conceptually like: username → Rahul 12. value Attribute value specifies a value for an input.

<input
    type="text"
    name="country"
    value="India">

The input starts with India as its value. For radio buttons and checkboxes, value identifies what was selected.

<input
    type="radio"
    name="plan"
    value="premium">

13. placeholder

<input
    type="text"
    placeholder="Enter your name">

Common use cases include: • Comments • Feedback • Messages • Descriptions 13. Select Dropdown A dropdown can be created using <select> and <option>.

<label for="city">City</label>

<select id="city" name="city">
    <option value="pune">Pune</option>
    <option value="mumbai">Mumbai</option>
    <option value="delhi">Delhi</option>
</select>

14. Complete Form Example

<form>

    <label for="name">Full Name</label>
    <input
        type="text"
        id="name"
        name="name"
        required>

    <label for="email">Email</label>
    <input
        type="email"
        id="email"
        name="email"
        required>

    <label for="password">Password</label>
    <input
        type="password"
        id="password"
        name="password"
        required>

    <label for="city">City</label>
    <select id="city" name="city">
        <option value="pune">Pune</option>
        <option value="mumbai">Mumbai</option>
    </select>

    <label for="message">Message</label>
    <textarea
        id="message"
        name="message">
    </textarea>

    <button type="submit">Register</button>

</form>

15. How a Form Works A typical form flow is: User enters information ↓ HTML form ↓ Submit ↓ Browser sends data ↓ Backend receives data ↓ Backend processes it ↓ Database may store it ↓ Response sent back HTML creates the form, but HTML alone doesn't create a complete registration or login system. JavaScript and backend technologies will later handle more advanced behavior and data processing. 🧠 Remember <form> → Form container <label> → Describes an input <input> → Single-line input <textarea> → Multi-line input <select> → Dropdown <option> → Dropdown option <button> → Button required → Makes a value required Understanding forms is essential because almost every real-world web application needs to collect information from users.

🌐 Web Development Roadmap — Part 20 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>

The Finance cell spans two rows. 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. Double Tap ❤️ For More ----- 2.64 ₽ · /balance_help

🌐 Web Development Roadmap — Part 19 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>
