HTML Coding for Beginners: A Comprehensive Guide

Learning HTML coding can seem daunting at first, but with the right guidance, you can master the basics in no time. HTML is the backbone of the web, and understanding its structure is essential for building websites.

HTML coding is made up of elements, which are represented by tags. These tags are used to define different parts of a web page, such as headings, paragraphs, and images. Every element has a corresponding closing tag, which is used to end the element.

To write HTML code, you need to use a text editor or an Integrated Development Environment (IDE). A text editor is a simple tool that allows you to write and edit plain text files, while an IDE provides a more comprehensive set of tools for coding, debugging, and testing.

HTML Attributes are a crucial part of writing clean and effective HTML code. Always quote attribute values, as developers normally do, and it makes the code easier to read.

Quoted values are also a must if the value contains spaces. This is a simple yet important rule to follow.

To make your web page more accessible, always specify the alt attribute for images. This attribute tells the browser what text to display if the image can't be loaded.

You should also define the width and height of images to reduce flickering and improve performance.

Here are some common image attributes to keep in mind:

Always quote attribute values, as it's a good practice that developers normally follow. This makes the code easier to read.

Always specify the alt attribute for images. This attribute is important if the image for some reason cannot be displayed.

It's a good idea to define the width and height of images. This reduces flickering, because the browser can reserve space for the image before loading.

The alt attribute tells the browser what text to display if the image can't be displayed and should be included with any image. It's an accessibility feature, and screen readers will read the alt text aloud.

You can set the height and width of an image using the "height" and "width" attributes. However, it's a good idea to only set one of them so the image scales correctly.

Here are the key image attributes to include:

HTML tags are the building blocks of HTML coding, and they play a crucial role in determining how web browsers display content.

Tags have three parts: the opening tag, the content, and the closing tag.

The opening tag is the part of the tag that starts with a less-than symbol (<) and tells the browser what type of content to expect.

The content is the actual text or media that is being displayed on the web page.

The closing tag is the part of the tag that ends with a forward slash (/) and tells the browser that the content has ended.
