and space in HTML tips and techniques

There more to white-space than the spacebar. Computers have many ways of encoding space in documents, be they emails, PDFs, or HTML. The non-breaking space character (  character in HTML) is commonly used to separate strings and denote a string that should not be put onto a separate line after the space.

What are HTML entities?

In HTML or emails containing HTML some characters need to be encoded as HTML entities in order to be read by a computer. These include currency symbols like € or £ or the less than or greater than symbols: < and >. The HTML entities are special strings that denote such characters. Here are some examples:

• Non-breaking space ;
• Less than < <
• More than > >
• Ampersand & &
• Euro € €
• Pound £ £

What is nbsp and what does it do?

Spaces in emails

Emails are notoriously difficult to style and space content. For many years developers and email markerters have styled emails using tables and unfortunately that is still the case today. However table cellpadding or css padding properties let you space content quite accurately using HTML.
