To minify
The verb “to minify” means to make something smaller. In web design and development this refers to the process of removing unnecessary whitespace and other characters from HTML, CSS, and JavaScript to make them download more quickly. While many developers minify their HTML, CSS, and JavaScript using a program, I don't recommend it in most cases. Because programs tend to be very literal and can remove things that should be left in the file. Instead, if you need to minify your HTML, CSS, and JavaScript, you should do it manually and very carefully.
What Can Be Removed to Minify HTML? To minify HTML effectively, you can remove: Carriage returns, White space surrounding tags (such as tabs to indent the code), Closing slashes (/) on tags in documents that are not using an XHTML doctype. You should never remove quotation marks around tag attributes. What Can Be Removed to Minify CSS? To minify CSS effectively, you can remove: Carriage returns, White space surrounding CSS properties (such as tabs to indent the code), The last semicolon (;) in a style property.
To validate
When you validate a web language like HTML, XML, or CSS, you are checking it against the standard for that language. In most cases, the standard you want to validate against is defined at the top of the document in the DTD.
Example: to validate an HTML 4 we need to indicate: <!DOCTYPE HTML PUBLIC "//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/strict.dtd">
Tracking or Kerning
The adjustment of spacing between pairs of letters in words. Usually defined by the font family. Kerning creates letter forms similar to ligatures when the letters are pushed together until they are touching. Kerning is a form of micro whitespace that allows you to control the legibility of text on Web pages.
Typography
Letters, numbers and symbols define the design of the types used in any web. Typography is normally referred to the global design more than to a specific family or category.
