Online HTML Editor: Live Preview & Run HTML, CSS & JS

Are you looking for a way to write code online that is easy to use and gives you the features you need? Meet the Codlico HTML Editor. It is an online tool that makes your coding easier and more fun. The editor is developed in three sub-editors: one for HTML, a second for CSS, and a third for JavaScript. Each editor includes different tools to help you create web projects without extra work.

First, you’ll write a code. Next you format it and preview the project. In addition, during coding, the editor guides you step by step about its features.

In this tool, you can write HTML, CSS, and JS while also instantly formatting and previewing the code. Also, with shortcuts you can move a line or code block up or down, copy, cut, paste, or select text quickly. On the other hand, if your code is not well formatted so the formatter will fix it in milliseconds. For example, you press Ctrl + I, and the formatter cleans the code.

Whether you are a beginner learning frontend basics or a pro who wants a smooth coding flow, the Codlico HTML Editor fits your needs. In this post, I will show you the editor’s features and how the editor makes the coding process easier and more enjoyable. Now, let’s break down the features.

HTML Editor

The HTML Editor is where you build a web page structure with tags and elements. You write HTML code such as tags, attributes, and other elements. First, in the style tag you write will inline CSS or link an external stylesheet. Similarly, you place JavaScript in the script tag or connect an external script file.

CSS Editor

Now, the CSS Editor is your styling place. This is where you create styles for your HTML or develop an external stylesheet. It also includes line numbering, code folding, error detection, shortcuts, and a formatter. In addition, it has a color picker tool that helps you avoid guessing hex codes. For example, turn it on, pick a color, and the tool inserts the value into your code.

JS Editor

The JS Editor adds behavior to web pages. This editor only supports JS code in which you write code to make elements movable, respond to specific click functions, or manipulate. Moreover, there are line numbers, which help to track the code; code block expand/collapse; errors and syntax checker; handy shortcuts; and a code formatter, so with these features you can easily keep your code clean and make it easier to work with.

Briefly, the HTML, CSS, and JS editors have helpful tools for building, styling, and scripting. So, you complete all tasks in a few steps and with fewer errors in one place.

Real-Time Instant Preview/Output

Suppose that you’re drawing a design on your tablet, and each line instantly appears on the screen. Similarly, the real-time instant preview in this HTML editor does for your code. Even if you’re coding in any editor so each change is automatically displayed on the live preview. For example, adding a button or changing a color shows up live in the output. There are no delays.

First, you don’t switch between writing code and checking the result. Each keystroke shows your work right away. This speeds your work and keeps your focus.

In addition, you add libraries and web fonts without copying and pasting code. You plug in Bootstrap for layouts and Font Awesome for icons with no extra steps. This saves time.

Open Existing File (.html, .css & .js)

Open supported files like .html, .css, and .js from your device. The process is simple; first of all, click on the “Open” button or press (Ctrl + O) to browse files, then double-click on a supported file, and the code will load to the editor. In the same way, it also supports drag and drop for opening files. Normally, drag a file and drop it into the editor so the file will open without extra steps. For example, drop index.html to open that page. You can then edit HTML, CSS, or JavaScript.

Downloads: Code and Preview

Ready to save your code? The HTML Editor lets you download a single file, all your code at once, or a preview of your project. It makes the process quick and simple. Next, you see how to save and share your work with a few clicks.

Single & Zip Code Files Download

If you want to save one file from the HTML, CSS, or JavaScript editor, click the “Save” button or press Ctrl-S. The file is then downloaded to your device.

If you want to download all your code files, click the “Zip Download” button or press Ctrl-K. The editor bundles all the files into one zip file. Then you can transfer or store all the files together.

Download Preview as JPG & PDF

If you want to save a view of your project, go to the preview section and click the JPG button at the bottom left or press F10. Then the preview downloads as a JPG image.

If you prefer a PDF, click the PDF button in the same spot or press F12. Then the preview downloads as a PDF.

These download options enable you to save or share your code and its previews. Use these buttons to save, download, or share your project.

Appearance & Modes

Do you ever wonder what makes an editor easy to use? The HTML Editor shows a clear look and several modes that help you write code and view results. We review how it looks and how you can change its layout and behavior.

Action Panel

You use this panel to run common actions quickly. Additionally, it groups the tools you need to keep coding without extra clicks.

Open Existing File

You click this to load .html, .css, or .js files into the editor. This opens files you are already working on.

Save File

You click this to download the file you are editing. In addition, it saves a copy to your device.

Download All as ZIP File

Search in Code

You use this to find text in your project fast. For example, you can search for a class name or a tag.

Reset Editor Names

You click this to return editor titles to their default names. Moreover, this helps if you rename tabs and want to undo the changes.

65+ Devices Preview

You choose from over 65 device sizes or enter a custom size to test responsiveness in real time. In particular, you can check how the layout adapts to different screen widths.

Layout Modes

You change how you view the editor and the output by switching layout modes. First, you can view only the preview. Second, you can view only the code. Third, you can view both at once.

Full Preview Mode

This mode shows only the project output and hides the editors. As a result, you focus on the final page.

Full Code Editor Mode

Full code editor mode shows only the code editors and hides the preview. Therefore, you focus on writing and editing code.

Column Mode (Code + Preview)

Column mode shows the code editor on the left and the preview on the right side of the app. This enables editing and testing of results at the same time.

Dark/Light Mode

This feature toggles between dark and light themes to reduce eye strain or to match your preference. Additionally, the setting applies to the editors and the interface.

Full Screen Mode

You expand the editor to fill the screen or exit full screen when you finish. This mode gives you more space for editing and viewing.

Editor Resizing Mode

The editor’s default size is 700px, and also you can stretch it to full screen or shrink it back to its default size. Consequently, you have control over how much space is needed for the editor.

Editor & Preview Navigation

You are ready to work through your code. The HTML Editor’s navigation tools help you code more easily. We explore how these features add value to your workflow.

• Line Number: Every code row gets a clear number. You see the size of your project at a glance.
• Folding and Unfolding Code Blocks (Collapse/Expand): You hide or show sections such as HTML’s <body>, CSS {} or JS {} with a click or press Ctrl-Q. This helps you focus on the area you need.
• HTML Tags Hints: When you type a tag, the editor suggests options to keep you moving faster.
• Attributes and Token Hints in Tag: The editor shows attribute suggestions for tags. For example, it shows the attribute “href” in <a> and hints inside style and script tags.
• CSS Hints: The CSS editor shows property and value hints as you type. This helps you choose the right rule.
• JavaScript Hints: The JS editor shows keyword and method suggestions at the right time to help you write code faster.
• Colored Code (Both in Light and Dark Mode): Code uses color in light and dark themes so you read it more easily.
• Find & Replace: You search for code parts and swap them, including support for regex for power users.
• Active Line or Cursor Line Highlight: The editor highlights your current line so you always know where you are.
• Status Bar: The bottom-right bar shows your cursor line and column, plus total lines and character count. You track position and size this way.
• Built-in Code Error Checker: Errors and warnings get highlighted with clear marks. You spot and fix problems faster.
• Brackets Matching: Matching brackets light up so your code stays structured.
• HTML Tags Matching: HTML tags glow to show their pairs, which helps you avoid unclosed tags.
• Auto Close Brackets and Tags: When you start a bracket or tag, the editor finishes it for you. This saves a step.
• Auto Complete: The editor predicts and completes code as you type. You accept suggestions to keep flow.
• Color Picker in CSS Editor: You pick colors directly in the CSS editor to set styles quickly.
• Editor Zoom: You change the code view size with zoom in or out to fit your needs.
• Preview Zoom: You scale the live preview to check visual detail.

Editor Save System

Do you worry about losing your code? The HTML Editor uses a save system that keeps your work and enables you to keep coding. The editor saves every keystroke so if you close your browser tab by accident, your code stays safe and you can return to it.

Automatic Code Save

The editor saves each keystroke automatically. If you close the browser tab, the editor restores your code when you return. This removes the need to save by hand.

Save Code to ToolKit

You can save code to the ToolKit for later. You pick a group to store it, or it goes to “ungrouped” by default. You can rename, move, delete, or update saved code at any time. For example, if you do not choose a group, the code goes to “ungrouped”.

Other Events Save Systems

The editor also saves your cursor position so you return to the same spot. It remembers which tabs are open and your theme choice, dark or light. This helps you start where you left off.

For example, if you type an expression (i.e., div>ul>li) and then press Tab, the editor expands this expression into a complete code block. These shortcuts enable you to build structures in seconds. Instead of typing every tag, you let the editor do the work.

How to remember:

• > for child
• + for sibling
• ^ to climb up (close the current node)
• *n to repeat
• $ in class/text to inject the index
• () to group sub‑trees
• [...] for attributes
• {…} for text content

CSS Shortcuts

You style your project without extra typing. The CSS Editor’s shortcuts expand short codes into full CSS rules when you press a key. Now we check how it works.

Type m10 and press Tab. It expands to margin: 10px;. This saves you from typing each property in full. The feature speeds up styling and lets you focus on design, so you do not need to type every property when a shortcut expands it.

• m10 + Tab → margin: 10px
• p20-10 + Tab → padding: 20px 10px
• bd1-s#f00 + Tab → border: 1px solid #f00
• pos:a + Tab → position: absolute;

How to Get Started!

Are you ready to start coding with the Codlico HTML Editor? Open the editor in your web browser and create a new project by setting up files. Follow the below steps to start and get results:

Start Coding in HTML, CSS, or JavaScript:

There are three separate editors for HTML, CSS, and JS in which you can structure, style, and add functions. Next, add HTML tags, selectors, properties, and functions to build a page step by step in less time.

See Your Code Come Alive Instantly:

The editor shows a live preview as you type. Every change appears beside the editor, and the preview updates in real time. You catch layout or script issues quickly and fix them right away.

Code Formatter:

Use the formatter to format your written code; after formatting, it will become easier to read the code.

Test Responsiveness of Your Web Page:

Next, use the built-in over 65+ devices frames to check how your project looks on desktops, tablets, and phones. Adjust your CSS until the site works well on each device.

Save Your Work Locally:

Download your files to save them on your device. You store the files in a folder so you can open them later in any browser.

Export Your Project for Other Uses:

Lastly, export all your written HTML, CSS, and JavaScript code. Download a single file of code or download all at once as a zip file. For example, move index.html and styles.css into another project and continue working there.
