Welcome back, aspiring web developers! In our previous articles, we covered the basics of HTML5 and its elements. Now, it’s time to take your web development skills to the next level by learning about HTML attributes, forms, and how to style your HTML with CSS.
Understanding HTML Attributes
HTML attributes provide additional information about HTML elements. They are always included in the opening tag and usually come in name/value pairs like name="value"
.
Common HTML Attributes
id
: Specifies a unique id for an HTML element.
<p id="unique-paragraph">This paragraph has a unique id.</p>
class
: Specifies one or more class names for an element, which can be used by CSS and JavaScript.
<p class="text-center">This paragraph belongs to the 'text-center' class.</p>
src
: Specifies the source of an image, script, or iframe.
<img src="image.jpg" alt="A beautiful scenery">
href
: Specifies the URL of a link.
<a href="https://www.example.com">Visit Example</a>
alt
: Provides alternative text for an image if it cannot be displayed.
<img src="image.jpg" alt="A beautiful scenery">
title
: Adds extra information about an element, displayed as a tooltip when the mouse hovers over it.
<p title="This is a tooltip">Hover over this text to see the tooltip.</p>
Example of Attributes in Use
<a href="https://www.example.com" id="example-link" class="link-class" title="Go to Example.com">Visit Example</a>
Creating Forms in HTML
Forms are essential for collecting user input. HTML forms use various elements to capture different types of data.
Basic Form Elements
<form>
: Defines the form.
<form action="/submit-form" method="post">
<!-- Form elements go here -->
</form>
<input>
: Defines an input field.
<input type="text" name="username" placeholder="Enter your username">
<label>
: Defines a label for an input element.
<label for="username">Username:</label>
<input type="text" id="username" name="username">
<textarea>
: Defines a multi-line text input.
<textarea name="message" rows="4" cols="50">Enter your message here...</textarea>
<button>
: Defines a clickable button.
<button type="submit">Submit</button>
Example Form
<form action="/submit-form" method="post">
<label for="name">Name:</label>
<input type="text" id="name" name="name" placeholder="Enter your name">
<label for="email">Email:</label>
<input type="email" id="email" name="email" placeholder="Enter your email">
<label for="message">Message:</label>
<textarea id="message" name="message" rows="4" cols="50" placeholder="Enter your message"></textarea>
<button type="submit">Submit</button>
</form>
Styling HTML with CSS
CSS (Cascading Style Sheets) is used to control the look and feel of your HTML elements. It allows you to separate the content from the presentation, making your code cleaner and more maintainable.
Adding CSS to HTML
- Inline CSS: Adds CSS directly to an HTML element using the
style
attribute.
<p style="color: blue; font-size: 18px;">This is a styled paragraph.</p>
- Internal CSS: Adds CSS within a
<style>
tag in the<head>
section of your HTML document.
<head>
<style>
p {
color: blue;
font-size: 18px;
}
</style>
</head>
- External CSS: Links to an external CSS file using the
<link>
tag.
<head>
<link rel="stylesheet" href="styles.css">
</head>
Basic CSS Syntax
CSS rules are made up of selectors and declarations. The selector points to the HTML element you want to style, and the declaration block contains one or more declarations separated by semicolons.
selector {
property: value;
property: value;
}
Example CSS Rules
/* Selects all <p> elements */
p {
color: blue;
font-size: 18px;
}
/* Selects the element with id="unique-paragraph" */
#unique-paragraph {
color: red;
}
/* Selects all elements with class="text-center" */
.text-center {
text-align: center;
}
Example of HTML with CSS
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Styled HTML Page</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<p class="text-center">This is a centered paragraph.</p>
<p id="unique-paragraph">This paragraph has a unique style.</p>
</body>
</html>
And here’s what the styles.css
file might look like:
p {
color: blue;
font-size: 18px;
}
#unique-paragraph {
color: red;
}
.text-center {
text-align: center;
}
