Notes on Using Online HTML Editors
Online HTML editors provide great convenience for front-end development, web design, and content editing. But users should still attend to certain important details to have a good development experience and efficient results.
-
A number of online web content composers lack both automatic saving and cloud backup features. You should check if the project is compatible with local downloads, cloud backup, or GitHub connection to prevent losing your code.
-
Some browsers may make it difficult for editors to work properly (for instance, Safari and old versions of IE). You should install and run the newest Chrome or Edge if you wish to see the best performance.
-
Know how resources are introduced and what the quota system is ahead of time. Certain tools restrict the inclusion of items like JS libraries and images in the free version, which changes how the site looks.
-
Some online HTML code editors are not built for large-scale web development projects. Some development tools are better for showing how something works, checking results, or writing code.
Though these tools allow designers to be creative, many additional features require working with code, configuring frameworks, and so on. First-time users need to understand the technical part of the tools.
