As with HTML, these indentations help keep our code organized and legible. Knowing a few common terms and the general syntax of CSS is a great start, but we have a few more items to learn before jumping in too deep. Specifically, we need to take a closer look at how selectors work within CSS. Selectors, as previously mentioned, indicate which HTML elements are being styled. It is important to fully understand how to use selectors and how they can be leveraged.
The first step is to become familiar with the different types of selectors. Type selectors target elements by their element type. The following code shows a type selector for division elements as well as the corresponding HTML it selects. Class selectors are a little more specific than type selectors, as they select a particular group of elements rather than all elements of one type.
Class selectors allow us to apply the same styles to different elements at once by using the same class attribute value across multiple elements.

Here the ID selector will only select the element containing the id attribute value of shayhowe. These selectors are also only the beginning. Many more advanced selectors exist and are readily available. All right, everything is starting to come together. Using a single external style sheet allows us to use the same styles across an entire website and quickly make changes sitewide.
Other options for referencing CSS include using internal and inline styles. You may come across these options in the wild, but they are generally frowned upon, as they make updating websites cumbersome and unwieldy. Because we are linking to CSS, we use the rel attribute with a value of stylesheet to specify their relationship. Furthermore, the href or hyperlink reference attribute is used to identify the location, or path, of the CSS file. In order for the CSS to render correctly, the path of the href attribute value must directly correlate to where our CSS file is saved.
In the preceding example, the main. If our CSS file is within a subdirectory or subfolder, the href attribute value needs to correlate to this path accordingly. For example, if our main.

Every web browser has its own default styles for different elements.
How Google Chrome renders headings, paragraphs, lists, and so forth may be different from how Internet Explorer does. To ensure cross-browser compatibility, CSS resets have become widely used.
These resets generally involve removing any sizing, margins, paddings, or additional styles and toning these values down. Because CSS cascades from top to bottom—more on that soon—our reset needs to be at the very top of our style sheet. Doing so ensures that those styles are read first and that all of the different web browsers are working from a common baseline. There are a bunch of different resets available to use, all of which have their own fortes. If you are feeling a bit more adventurous, there is also Normalize.
As previously mentioned, different browsers render elements in different ways. Which browsers you wish to support, and to what degree, is a decision you will need to make based on what is best for your website.
