In this article, we will discuss HTML syntax and pattern. If you maintain your HTML code in an organized, consistent, and clean manner, it will be easier to read, understand, and maintain.
Here are some guidelines for those who would like to learn how to write proper HTML code.
First Always Declare Document Type
Make sure you declare the document type at the very beginning of your document.
HTML documents should be typed as follows:
Close All HTML Tags
It is unnecessary to close all HTML elements like <p> tag in Html.
It is highly advised that you must close all HTML elements given in below example:
<p> Mr Examples
Use Lowercase Element Names
When naming elements, HTML allows uppercase and lowercase letters to be used together.
It is advised, however, that element names should be in lowercase, as follows:
- Mixed upper- and lowercase names look sloppy and are challenging to read.
- Lowercase names are usually used by developers.
- Utilizing lowercase is more appealing.
- There is less confusion when writing in lowercase.
Example:  Bad Practice
Always Quote Attribute Values
HTML Syntax allows attribute values without quotes.
Quoted attribute values are recommended, however, since:
- Attribute values are typically quoted by developers.
- Readability is improved by quoted values.
- Any value containing spaces MUST be enclosed in quotes.
The value contains spaces, so this won’t work:
Spaces and Equal Signs
Equal signs are permitted to have spaces around them in HTML. The space-less format is easier to read and makes it easier to group entities.
Example:  Bad Practice
Blank Lines and Indentation:
When we talk about HTML Syntax then, Indentations, spaces, and blank lines should never be added without cause.
When splitting lengthy or logical codes, add blank lines to enhance readability.
Added two spaces of indentation makes it more comfortable to read. It would be best if you did not use the tab key.
Good Table Example
Good List Example
Use Lowercase Attribute Names
You may use either capital or lowercase letters for an attribute’s name in HTML when it comes to HTML Syntax.
Attribute names should be lowercase, nevertheless, for the reasons stated below.
- Case-sensitive names are more professional looking than those that mix capitalization and lowercase letters.
- Coders often only capitalize the first letter of a name.
- The lowercase version is the more aesthetically pleasing one.
- Less mental energy is required while using lowercase letters.
Not Readable Document
Images should always include width, height and alt
Alt attributes should always be set for images. In the event that a picture cannot be portrayed for some reason, this attribute is essential.
Ensure that images are always described in terms of their width and height. Because of this, flickering is decreased. The browser can commit the area before loading the picture. This is an excellent guide to HTML Syntax.
Shorten Your Code
Scrolling right and left are not fortunate for reading HTML code in an HTML editor.
Whenever possible, dodge writing lengthy code lines. The HTML Syntax & Pattern is defined here.
Don’t Ignore the <title> :
HTML mandates the title element. SEO (search engine optimization) relies heavily on the content of a page title. In search results, search engines use page titles to determine their order. This document describes the proper HTML Syntax and pattern.
A title element consists of the following:
- Defining the title of the toolbar in the browser
- When a page is added to favorites, it receives a title.
- Search engine results include a title for the page.
Are you skipping the head?
There is also the choice of skipping the HTML <head> tag.
Head is default added to all elements before the body in most browsers.
Omitting <html> and <body>?
You should always add the <html> and <body> tags!
There may be errors in older browsers if you forget the <body> tag.
A DOM or XML software crash can also occur when <html> and <body> are forgotten.
Is empty HTML closed?
The closing of empty elements is optional in HTML.
The language and the character encoding of the HTML document should both be represented as earlier as feasible <meta charset=”charset”> to confirm the text will be appropriately comprehended and indexed by search engines.
Don’t Miss lang Attribute:
It is still advised to have the lang attribute within the <html> tag to declare the language of the Web page. Search engines and browsers will benefit from this when it comes to HTML Syntax .
Viewports are areas of a website which are visible to the user as they navigate it. Mobile phones have smaller screens than computers, so they will differ depending on the device as it comes to HTML Syntax.
On all your web pages, you should include the following:
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
It tells the browser how to regulate the size and dimensions of the page.
By setting the width=device-width part, the width of the page is determined by the device’s screen width (which may vary).
When the browser preferably loads the page, the initial-scale=1.0 part sets the zoom level.
The following are examples of web pages without and with viewport meta tags:

You should write short comments on a single line, like this:
<!– This is a comment –>
For comments that span more than one line, write them as follows:
When long comments are indented with two spaces, they are much simpler to understand and analyze. Adhering to the principles of HTML Syntax is a recommended best practice.
You should use straightforward syntax for linking to style sheets if you wish to follow HTML Style Syntax And Pattern. (the type attribute is not necessary)
The following is an example of a short CSS rule that can be shortened:
It is best to document lengthy CSS rules over numerous lines:
font-family: “Arial Black”, Helvetica, sans-serif;
Please keep this in mind:
- Ensure that the opening bracket and the selector are on the same line
- The opening bracket should be preceded by one space
- You should use two spaces for indentation
- You should use a semicolon after each property-value pair, including the last one
- You should only use quotes around values if they contain spaces
- Do not include leading spaces in the closing bracket
Load external scripts using simple syntax (the type attribute is not needed):
Proper File Extensions:
A .html extension is required for HTML files (.htm is also acceptable).
.htm vs .html – What’s the difference?
It does not matter whether the extension is .htm or .html – Any web browser and the server will treat both as HTML.
Lower Case File Names:
Other web servers (Microsoft, IIS) don’t care about case: “Newyork.jpg” works too.
You must be careful with mixed case. Even little faults can destroy your site if you switch to a case-sensitive server.
Lowercase file names prevent these issues.
It is standard practice for web servers to add a default filename to URLs without specifying one (for example, “https://mrexamples.com/”)
The default.html, default.html, or default.htm file.
Your server must be configured with a default file name of “index.html”, not “default.html”.
In most cases, server configurations allow for more than one default filename; you can usually set up an unlimited number.
Importance of HTML Syntax And Pattern
Importance of HTML Syntax and Pattern The syntax and pattern of HTML play a vital role in creating well-structured and readable web pages. Here are some reasons why they are important:
- Consistency: HTML syntax and pattern provide a standard set of rules that ensure consistency across different web pages. This consistency makes it easier for users to navigate the web and find the information they need.
- Accessibility: HTML syntax and pattern help to ensure that web pages are accessible to everyone, including people with disabilities. By following the correct syntax and pattern, web developers can create web pages that are compatible with assistive technologies such as screen readers.
- Search Engine Optimization (SEO): HTML syntax and pattern play a crucial role in SEO. Search engines use these rules to crawl and index web pages, which affects their ranking in search results. By following the correct syntax and pattern, web developers can improve the visibility of their web pages in search results.
- Readability: HTML syntax and pattern make web pages more readable by providing structure and hierarchy. Headings, paragraphs, and lists are just a few examples of HTML elements that help to organize content and make it easier to read.
