In today’s digital age, having knowledge of HTML is an essential skill for anyone who wants to create a website. HTML is the standard markup language for creating websites and is used to structure the content of web pages. In this article, we will provide a comprehensive guide on how to write html code , including key points, important points, and helpful points for beginners.

Getting started with HTML

To start writing HTML code, one needs a text editor like Notepad or TextEdit. These are basic editors that are pre-installed on most computers. They are simple to use and can be used to write and edit HTML files. Once you have a text editor, you can start writing your HTML code.

The basic HTML format starts with a “document type” tag (). This tells the web browser which version of HTML you are using. Following the document type tag, you will need to include the HTML opening tag () and the HTML closing tag (). All the content of your web page will be added between these two tags.

HTML tags are written inside angle brackets and tend to come in pairs (opening and closing tags). For example, the

tag is used to specify the title of the web page, and it should be closed with a tag. Different tags can be used for formatting, such as for bold text and for italic text.

Additional HTML Formatting Elements

HTML Formatting Elements include for important text and for smaller text. These tags can also be used for adding comments and computer code elements. HTML code can be written directly in the HTML markup without any CSS. This is useful for when you want to add a small piece of code to your web page.

The HTML title tag is used for specifying the title of a web page. It should be placed in the head section of your HTML document, between the

and tags. The title should be relevant to the content of the page and should include relevant keywords.

HTML DOM (Document Object Model)

HTML DOM (Document Object Model) is a programming interface for web documents. It represents the page so that programs can change the document structure, style, and content. The HTML html tag is the root element of an HTML document. HTML attributes provide additional information about html elements . They are always specified in the start tag and are separated from the tag name by one or more spaces. The HTML comment tag is used for adding comments to the code that are not visible on the web page. Comments are useful for adding notes to your code that explain what the code is doing.

Saving and Viewing HTML Documents

HTML documents can be saved as “.html” files and viewed in a web browser. To view your HTML document, simply open it in your web browser. Advantages of using HTML include its simplicity, compatibility with all web browsers, and accessibility. Disadvantages of using HTML include its limitations in creating complex designs and the need for additional languages like CSS and JavaScript for more advanced features.

Tips for Writing Good HTML Code

Tips for writing good HTML code include using proper indentation and commenting the code. Proper indentation makes the code easier to read and understand. Commenting the code helps others understand what the code is doing. Best practices for creating web pages include optimizing images, using responsive design, and ensuring accessibility for users with disabilities . Popular programming languages for web development include JavaScript , Python, and Ruby. These languages can be used to make web pages more interactive and dynamic.

Common issues with HTML code include broken links, incompatible tags, and slow loading times. Broken links occur when a link points to a page that no longer exists. Incompatible tags occur when tags are used incorrectly, and slow loading times occur when the page is too large or contains too many images.

Frequently Asked Questions — FAQs

What is HTML, and why is it important for web development?

HTML stands for Hypertext Markup Language, and it is the standard markup language for creating web pages. It is important for web development because it provides the structure and content of a web page.

What are HTML tags, and how do they work?

HTML tags are used to define elements within an HTML document. They are written inside angle brackets and tend to come in pairs (opening and closing tags). Tags can be used for formatting, adding comments, and inserting computer code into a web page.

What is the HTML DOM, and how does it work?

The HTML DOM is a programming interface for web documents. It represents the web page as a tree-like structure, with each element as a node in the tree. JavaScript can be used to manipulate the HTML DOM and dynamically update the content of a web page.

How can I ensure that my HTML code is optimized for search engines?

To optimize your HTML code for search engines, you should use proper heading tags, include relevant keywords in your content, and make sure your web pages load quickly. You can also use meta tags to provide additional information about your web page to search engines.

What are some common issues with HTML code, and how can I fix them?

Common issues with HTML code include broken links, incompatible tags, and slow loading times. To fix these issues, you should validate your HTML code using a tool like W3C Markup Validation Service, use best practices for web development, and test your web pages on multiple browsers and devices.

Can I use HTML alone to create complex web designs?

While HTML can be used to create simple web designs, it has its limitations in creating complex designs. To create more advanced features, you may need to use additional languages like CSS and JavaScript.

HTML Style Guide

A consistent, clean, and tidy HTML code makes it easier for others to read and understand your code.

Here are some guidelines and tips for creating good HTML code.

Always Declare Document Type

Always declare the document type as the first line in your document.

The correct document type for HTML is:

Use Lowercase Element Names

HTML allows mixing uppercase and lowercase letters in element names.

However, we recommend using lowercase element names, because:

• Mixing uppercase and lowercase names looks bad
• Developers normally use lowercase names
• Lowercase looks cleaner
• Lowercase is easier to write

Good:

Bad:

Close All HTML Elements

In HTML, you do not have to close all elements (for example the

element).

However, we strongly recommend closing all HTML elements, like this:

Good:

Bad:

This is a paragraph.

This is a paragraph.

Use Lowercase Attribute Names

HTML allows mixing uppercase and lowercase letters in attribute names.

However, we recommend using lowercase attribute names, because:

• Mixing uppercase and lowercase names looks bad
• Developers normally use lowercase names
• Lowercase looks cleaner
• Lowercase is easier to write

Good:

Bad:

Always Quote Attribute Values

HTML allows attribute values without quotes.

However, we recommend quoting attribute values, because:

• Developers normally quote attribute values
• Quoted values are easier to read
• You MUST use quotes if the value contains spaces

Good:

This will not work, because the value contains spaces:

Always Specify alt, width, and height for Images

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

Also, always define the width and height of images. This reduces flickering, because the browser can reserve space for the image before loading.

Good:

Bad:

Spaces and Equal Signs

HTML allows spaces around equal signs. But space-less is easier to read and groups entities better together.

Good:

Bad:

Avoid Long Code Lines

When using an HTML editor, it is NOT convenient to scroll right and left to read the HTML code.

Try to avoid too long code lines.

Blank Lines and Indentation

Do not add blank lines, spaces, or indentations without a reason.

For readability, add blank lines to separate large or logical code blocks.

For readability, add two spaces of indentation. Do not use the tab key.

Good:

Famous Cities

Tokyo

Tokyo is the capital of Japan, the center of the Greater Tokyo Area, and the most populous metropolitan area in the world.

London

London is the capital city of England. It is the most populous city in the United Kingdom.

Paris

Paris is the capital of France. The Paris area is one of the largest population centers in Europe.

Never Skip the Element

The element is required in HTML.

The contents of a page title is very important for search engine optimization (SEO)! The page title is used by search engine algorithms to decide the order when listing pages in search results.

• defines a title in the browser toolbar
• provides a title for the page when it is added to favorites
• displays a title for the page in search-engine results

So, try to make the title as accurate and meaningful as possible:

Omitting and ?

An HTML page will validate without the and tags:

Example

This is a heading

This is a paragraph.

However, we strongly recommend to always add the and tags!

Omitting can produce errors in older browsers.

Omitting and can also crash DOM and XML software.

Omitting ?

The HTML tag can also be omitted.

Browsers will add all elements before , to a default element.

Example

This is a heading

This is a paragraph.

However, we recommend using the tag.

Close Empty HTML Elements?

In HTML, it is optional to close empty elements.

Allowed:

Also Allowed:

If you expect XML/XHTML software to access your page, keep the closing slash (/), because it is required in XML and XHTML.

Add the lang Attribute

You should always include the lang attribute inside the tag, to declare the language of the Web page. This is meant to assist search engines and browsers.

Example

This is a heading

This is a paragraph.

Meta Data

To ensure proper interpretation and correct search engine indexing, both the language and the character encoding charset«> should be defined as early as possible in an HTML document:

Setting The Viewport

The viewport is the user’s visible area of a web page. It varies with the device — it will be smaller on a mobile phone than on a computer screen.

You should include the following element in all your web pages:

This gives the browser instructions on how to control the page’s dimensions and scaling.

The width=device-width part sets the width of the page to follow the screen-width of the device (which will vary depending on the device).

The initial-scale=1.0 part sets the initial zoom level when the page is first loaded by the browser.

Here is an example of a web page without the viewport meta tag, and the same web page with the viewport meta tag:
