Whether you’re a web developer who builds blog templates for a living, or a web-savvy blog owner who prefers to make changes to your template using HTML, CSS or JavaScript, you may be interested in some enhancements that we made to Blogger’s Template HTML Editor.
Your blog’s HTML template is the source code that controls the appearance of your blog. This template can be customized to appear however you’d like. The improved HTML template editor now supports line numbering, syntax highlighting, auto-indentation and code folding to make editing your template much easier.
