Now that you’re aware of the benefits an HTML formatter brings, let’s walk you through using one. It all begins with accessing the online HTML formatter and pasting your original HTML code into the provided editor space. From there, you can select your desired indentation preferences, opting for spaces or tabs, and specify the number of spaces if spaces are chosen. You also have the option to configure the line wrapping options. This determines after how many characters lines should wrap, or you can choose not to wrap lines at all.

Once you’ve customized your settings, click the ‘Format HTML’ button to start the formatting process. You can then view the neatly formatted HTML code in the output area. The primary purpose of using an HTML formatter is to transform minified or unindented HTML code into a well-formatted and more readable output.

Paste Your Ugly HTML Code

To begin the transformation process, simply paste your minified or unindented HTML code directly into the online formatter. This direct copy-paste method is a quick way to input your code into the online HTML formatter’s text area. Alternatively, if you have an HTML file on your computer, you can also upload it directly to the formatter. Either way, getting your code into the formatter is as simple as a few clicks.

Customize Formatting Settings

Once your code is loaded into the formatter, the subsequent step involves personalizing your formatting settings. These settings allow you to create an output that matches your coding preferences and standards. For instance, you can customize the indentation style and size in the online HTML formatter. This gives your code a consistent look according to your or your project’s coding standards.

You also have the ability to select the desired indentation level for your formatted HTML code. Additionally, the tool provides the option to set line wrapping at a specific character count, improving the readability of your code. The formatting service may also allow you to specify the file encoding of the HTML document, ensuring the proper parsing and display of characters.

Retrieve Your Formatted HTML Output

After your code has been formatted, you can obtain your HTML output. The HTML formatter displays the code with clear indentations and syntax highlighting, while also preserving spaces and tabs between content tags to maintain valid content. This formatted HTML code can be saved locally by right-clicking on the page and choosing ‘Save as…’, allowing you to download it as an HTML file.

If you wish to download a complete webpage, you can select the ‘Webpage, Complete’ option, which saves the HTML along with a folder of associated resources like images and scripts. To make storage or sharing easier, the saved HTML file and its associated resources can be compressed into a single zipped file.

The Mechanics Behind HTML Code Formatting

Behind its functioning, the HTML formatter is driven by some intriguing technology. One key aspect is that online HTML formatter tools often use JavaScript formatting libraries that employ regular expressions to parse and beautify your code. This combination of technologies allows for efficient and reliable code formatting, ensuring that your HTML code is not only readable but also properly structured.

Leveraging JavaScript for Code Formatting

JavaScript is one of the pivotal technologies powering an HTML formatter. Online HTML formatter tools use JavaScript formatting libraries combined with regular expressions to indent your code and organize your HTML tags. Since the use of client-side JavaScript libraries for formatting occurs within your browser, your HTML data does not leave your local environment. This not only ensures speedy formatting but also enhances your privacy by reducing the chances of data interception.

The Role of Regular Expressions in Cleaning HTML Data

Another vital technology harnessed by HTML formatters is regular expressions, also known as regex. Regex is a sequence of characters that define a pattern for searching, matching, and manipulating text. In the context of HTML formatting, regex patterns can efficiently target specific sequences, characters, or structures within your HTML content, aiding the data cleaning process. For instance, a simple regex pattern such as <[^>]*> could be utilized to strip all HTML tags from your textual content. Regex can also be employed to selectively remove attributes or values from HTML elements, like class attributes or inline style definitions.

More complex regex patterns are capable of extracting specific data from HTML tags, for instance, hyperlinks using patterns designed to target the href attribute within anchor tags. One unique aspect of regex in HTML formatting is managing spaces. Regex must distinguish between whitespaces within text, which should remain, and those adjacent to block elements, which can be removed. Understanding this function of regex is key to preventing unexpected results in formatted HTML layouts and preserving intended content spacing.

Ensuring Security and Privacy with Online HTML Tools

As you utilize online HTML formatting tools, the security and privacy of your data emerge as key concerns. The good news is that this online tool, an HTML formatter, takes this very seriously. They have implemented measures to ensure your data is not only safe but also private. These tools do not save any user data on the server, offering a layer of privacy and peace of mind to users.

They also prevent potential security risks associated with data sharing by ensuring that the formatted HTML output does not expose your data to third parties.

No Server-Side Data Storage

One key measure that ensures your data’s privacy is the fact that HTML formatter tools do not save any user data on the server. This means that once you’ve formatted your HTML code and retrieved your output, your original code isn’t stored anywhere on the formatter tool’s servers.

Hence, you can confidently format your code, knowing that your data is safe and private.

Safe Handling of HTML Data

In addition to not storing your data, online HTML formatting tools also ensure the safe handling of your HTML data. Here are some security measures they implement:

  • They use HTTPS (SSL/TLS) to encrypt the data exchanged between the web server and your browser, preventing data interception.

  • They employ input and output validation practices to prevent security issues like injections or cross-site scripting attacks.

  • To verify legitimate user submissions and prevent automated or fraudulent submissions, these tools use tokens and captchas.

Finally, these tools ensure data security by not making your data visible to any third parties, as part of their commitment to privacy.

Before and After Using an HTML Formatter

  • Decrease page load times

  • Improve website performance However, this results in a code that is compressed to one line, with all white spaces, line breaks, and comments removed.

While this is great for performance, it creates a code that is hard to read and manage.

Here’s how to manually minify your HTML output:

The Beautified HTML Code Output

Now, let’s consider the same code after it has been formatted by an HTML formatter. The proper indentation in the beautified HTML code clearly displays parent/child relationships, emphasizing hierarchy and improving code readability. Line breaks and spacing around attributes within tags enhance the clarity of the code’s intent, making it easier to understand and modify.

Moreover, the beautified HTML output ensures that:

  • The character set declaration precedes all other elements for proper rendering

  • A simple and clear title of the site is included

  • Semantic classes and IDs are used in the beautified code

  • Images include alternate text along with height and width attributes for greater rendering efficiency and accessibility.
