How to modify html files

HTML files are one of the most widely used file types on the web and are the building blocks of many websites around the world today. At the same time, it is also one of the basic elements for learning web development. Therefore, it is very important to learn how to modify HTML files. Whether you modify it slightly or write it from scratch, we need some basic tools and knowledge to process HTML files. Below is a detailed guide.

1. Understand HTML

Before we officially start, let’s first understand what HTML is. It is the abbreviation of HyperText Markup Language. HTML is a language for building web pages in a way that is easy to understand and read by using features such as elements, attributes, styles, and scripts.

2. Get the HTML file

Then we need to get the HTML file we want to modify. It can come from multiple sources, such as a folder stored on your local computer, a shared location, or a URL on the network. When modifying HTML files on the local computer, we can use a text editor such as Notepad on Windows or TextEdit on Mac to edit. For HTML files on the Internet, we need to use a web browser to obtain them. First, open the web page we wish to edit and find the page source code in the browser.

3. Open the file

Once we have the HTML file, we can open it and start editing. After opening the HTML file using a text editor, we can see some tags and text. Tags are the core component of HTML and are used to describe the structure and content of a document. They are enclosed by a left angle bracket (<) and a right angle bracket (>) and contain the name of the element, such as the

paragraph tag.

4. Edit the file

Add or modify text between the tags in the file to modify the HTML file. For example: If we want to add a sentence to a paragraph, we just add some text between the

tag and the

tag like this:

This is a paragraph. New additions are here.

We can also modify element attributes. Properties are characteristics of an element such as color, font size, style, etc. They are contained within an element tag and connect the attribute name and attribute value with an equal sign (=). For example, if we want to change the font color to blue, we can modify the HTML code as follows:

This is a paragraph.

5. Save the file

After completing editing, save the modified HTML file. Please note that you must save the file you want to modify with the correct file extension (.html or .htm). If you are copy-pasting an HTML file directly from a web browser, be sure to save the file as a single HTML file and not as a copy of the web page's source code.

6. View through the browser

Finally, view the changes we made. After saving the file, we can open it in a web browser to see the new changes. Can be viewed in browsers such as Chrome, Firefox, Safari, Internet Explorer and Edge.

Summary

The above are the basic steps on how to modify HTML files. Some simple modifications, such as changing text or attributes, are easy to do. If we want to create our own web pages, we need to have a deeper understanding of the HTML language and web development.
