Why can't you just mix elements together to create things?
Elements have a certain reactivity with other elements. Generally, you need to create ions of an element to then combine it with something else (if we are considering things solid at room temperature). This is why in chemistry class most of the things that you mix to get a reaction are aqueous.

How do you write a CSS definition for an element's class and ID?
There are 3 normal ways to refer to an HTML element with CSS. The first is to simple use the element itself, i.e. if you want to reference every , it would look like this:div {property:value;}Note that using the element's name gives the least amount of weight for selector specificity.The second way to refer to an HTML element is by class. Multiple elements on a page can use the same class. This is a good way to group elements together that will have similar styles. In CSS, you reference the element's class using a period and then the name of the class.For example, if I wanted to make a list of sodas, and I wanted all of the sodas to have green text, except for cola which I want to have underlined blue text, I can give each cola item a class of 'cola'. Here's an example:PepsiSpriteCoke7-UpA&W.cola{color:blue; text-decoration:underline;}li{color:green;}In this example, 'Sprite', '7-Up', and 'A&W' will be green, but 'Pepsi' and 'Coke' will be blue and underlined. The cascade dictates that rules for the same elements that live farther down the stylesheet will overrule anything above it for those elements, but classes have more value to selector specificity, so 'color:green' will not override 'color:blue' because '.cola' has more weight than 'li'.The third way to reference an element is by its id. Id's have the most weight of anything for selector specificity. In other words, an id reference will override any rules of a class or an element reference. Id's are useful for targeting individual elements. Note: An ID can only be used once! You cannot have more than one element per page with the same ID.Ids are referenced with a '#' symbol.Using the same example, I want 'Pepsi' to have orange text to show that it is my favorite in the list. An easy way to make only 'Pepsi' a target is to use an id:PepsiSpriteCoke7-UpA&W#favorite{color:orange; text-decoration:none;}.cola{color:blue; text-decoration:underline;}li{color:green;}In this example, 'Pepsi' would be orange with no underline. Note that I put 'text-decoration:none' inside the ruleset for '#favorite'. I did that because everything that has a class of 'cola' will be underlined, but since id's hold ten times the amount of specificity weight that classes do and 100 times the weight of an element reference, the underline would not show up.Also, in my examples, I use styles inside a style tag on the HTML page. This is not best practice and was only done for the purposes of these examples. Whenever possible, you should put your styles in an external stylesheet and use a tag to call them into the page.
