A multivalue attribute is the practice of maintaining more than a single value in a database column. Lets say for example you want to know the hobbies for a client. The proper way to handle this is to maintain the data in a one - to - many child table. Another way is a multivalue field. This in effect is a text field (varchar, etc) that will contain one or more values, separated by a comma (as an example).
This of course is NOT the way to go and will cause performance problems in parsing the information and make many reports and logical use of the data very difficult (but possible).

How can you disable a particular part in the source code of CSS?
Put /* block comments */ around it, for example: style { attribute: value; attribute: value; attribute: value; } style { /* attribute: value; */ attribute: value; attribute: value; } or style { /* attribute: value; attribute: value; */ attribute: value; } or /* style { attribute: value; attribute: value; attribute: value; } */ And while this won't validate, attribute renaming uses a lot less typing (and I use it myself): style { xattribute: value; attribute: value; attribute: value; }
