HTML and CSS Editor: Basics

What is HTML and CSS Editor?

HTML and CSS editor is an advanced version of text editor. It provides an intuitive interface for writing and editing code and offers functionality to eliminate all sorts of errors, increase productivity, and turn your work into a pleasant pastime. The main features of code editors are

  • error checking,
  • syntax highlighting,
  • autocompletion,
  • formatting,
  • smart file browsing.

Depending on the manufacturer, this functionality may vary. Sometimes, you can get much more than that, while in other cases, you can enjoy only the essential instruments with all the extra bells and whistles coming with a paid version.

Since some developers prefer basic functionality and a primitive yet clean and neat interface, whereas the others adore customizing every detail of the appearance to meet the mood, each editor has its fan base. Though there is one thing for sure, whether you are a newbie or a seasoned developer, whether you prefer simple approaches or fancy ones, HTML and CSS editor is a highly recommended asset for your toolset.

The deal is, although a basic word processor that is native to any operating system lets you write code of any complexity right here right now, it has two significant flaws. First of all, originally, it is not intended for such purposes; therefore, there is no compiler or preview mode. Second, word processors are notoriously famous for adding mumbo-jumbo to the result snippet, nullifying all your attempts to create clean and optimized code. Let’s consider some more pros of using code editor in your work.

Pros of Using HTML and CSS Editors

The main advantages of using HTML and CSS editors over raw word processors are:

  • They create the cleanest code.
  • They speed up HTML coding.
  • They provide high productivity.
  • They have tools for troubleshooting.
  • They offer easier file editing.
  • They save time with autocompletion.
  • They support various languages, not only HTML and CSS but also JavaScript and PHP. Therefore, you can create the entire project within one interface using multiple tabs.
  • They have an easy integration of various files.
  • They come with extra functionality like built-in FTP, remote site management capability, multi-file finding and replacing, etc.
  • They are regularly updated so that you can enjoy the benefits of the new spec or even use tags or CSS properties that you do not know yet.

More so, you can add to this list some advantages of using WYSIWYG editors that are a particular type of code editors, such as:

Low-Code Website Builders

With Startup App and Slides App you can build unlimited websites using the online website editor which includes ready-made designed and coded elements, templates and themes.

Try Startup App Try Slides AppOther Products

  • A broad component library that includes lots of predefined graphics and templates;
  • A split-screen preview that displays all the changes;
  • Wide customization options;
  • No need for extensive coding skills so that even non-tech-savvy people can handle it.

To sum up, all you can do in the basic word processor is write, whereas, in HTML and CSS editor, you can create.

Differences Between WYSIWYG Editors and Code-based Editors

As you have already guessed, HTML and CSS editors come in two types. The first one is the WYSIWYG editor that stands for What You See Is What You Get. The second one is a basic code editor that mostly reminds a regular text editor with some substantial bells and whistles.

The first type focuses on providing a comfortable environment for non-tech-savvy people, all the inexperienced developers who only start their career and developers who want to save their precious time. As a rule, it includes ready-made templates or stylish field-tested units that meet all the current standards, instant preview, and a handy drag-and-drop playground with numerous customization options.

The Slides is a perfect case in point. It lets you shape your idea within minutes. It has more than 200 stylish slides, 30 panels, and a bunch of tiny components. Every element is easy to set up and customize. Unlike its competitors, it generates clean, fully optimized code that can be easily understood.

WYSIWYG Editors and Code-based Editors

Static css editor

Static App Editor

The Static.app CSS editor is a tool or feature within the Static.app platform, designed for editing CSS.

  1. Syntax Highlighting: A CSS editor offers syntax highlighting, making it easier to distinguish between different elements like selectors, properties, and values by coloring them differently.
  2. Code Autocompletion: This feature partially typed CSS properties or values, speeding up the coding process.
  3. Error Checking: A good CSS editor provide real-time error checking or linting, highlighting syntax errors or potential issues in your CSS code.
  4. Responsive Previews: the CSS editor offers a preview feature that allows developers to see how their styles will look on different devices or screen sizes.
  5. Integration with HTML and JavaScript: Offers seamless integration with HTML and JavaScript, allowing for a more comprehensive development experience.
  6. Version Control Integration: Integrates with version control systems like Git, allowing developers to track changes and collaborate more effectively.
  7. Customization and Extensions: Allows customization of the workspace and offer extensions or plugins to add additional functionality.

The second option is, of course, for developers who are ready to get their hands dirty. Although code-based editors do not have an instant preview and visual builder, they are still universal tools to create any project. They give you complete control over your code. You can easily extend its functionality with the help of third-party plugins. They provide freedom and give you all the necessary tools to realize a project of any scale.

To sum up, each type has its own merits. Depending on the situation, you may find a useful one or another. Sometimes experienced developers use WYSIWYG editors to save time; sometimes, newbies go for traditional code-based editors to gain experience and learn new stuff.
