You have learned some new terms and concepts in CSS. If you don't understand the ones listed below you should go back and do the tutorial again! You don't need to remember it all but you do need to understand it when you read it:
- styles can appear in three different locations (an external file, an embedded style sheet or in-line) and the styles in those three locations can conflict with each other
- more specific styles (e.g. those applied with classes, ids or pseudoclasses) can override more general ones (types) if they conflict
- styles which appear later will override the earlier ones if they conflict
- a style sheet is a collection of style rule sets
- a selector (type, class or id) is the thing which tells the browser what you want to style with a rule set
- a rule set is a set of rules which will apply to the selected element(s) and is enclosed in curly brackets
- a rule is where you tell the browser how you want the thing(s) styled
- each rule will be an attribute (the specific thing you want changed for example color), a colon and at least one value (but possibly more separated by commas)
- if there is more than one value (e.g. a list of fonts) the browser will use the first one which works and ignore the rest
If you remembered all that well done. You still need to practise though to be sure you retain all the skills you have learned, That comes next.
If CSS ever fails to work try the W3C validator for CSS. It works much like the HTML one but just paste in the CSS not any HTML.
