Three reasons to use CSS on a web page are:

1. Clean Source Code, 
2. Separation of Content and Presentation
3. Consistency of Page Design

It is a good reason to configure both the text color and the background color because  the page will not be plain and to attract people to read the page.


3. Describe one advantage to using embedded styles instead of inline styles.

Both styles are great for quick fixes or prototyping but embedded styles is easier to cut out of the final prototype and put into an external file when templates are done.


 Checkpoint 3.2

1. Describe a reason to use embedded styles. Explain where embedded styles are placed on a web page.

A reason to use embedded styles is it allows us to override the rules of an external style sheet. Embedded styles are set in the HEAD section of your web page.

2. Describe a reason to use external styles. Explain where external styles are placed and how web pages indicate that they are using external styles.

A reason to use external styles is that it can change that one external file, and have that change reflected on every page of your site that links to the external CSS file. Any or all methods of implementing CSS can be used on the same page. An external style is simply a link placed in the HEAD section of your web page to a separate file containing your style rules.

3. Write the code to configure a web page to associate with an external style sheet called mystyles.css.

body {
    background-color: lightblue;
}

h1 {
    color: navy;
    margin-left: 20px;
}

Weekly blog entries, Chapter 2: HTML basics

Checkpoint 2.1

Describe the origin, purpose, and features of HTML.

HTML was created as a language that would enable researchers to share, structure, cross-reference documents.
 
The purpose of HTML is to provide a set of general rules that suggest how content should look when rendered. A markup language doesn't dictate the methods used to display the content, nor does it have foreknowledge of the target context, so this control is imprecise.

Each individual markup code is referred to as an element or tag. (each tag has its purpose)

Heading elements are organized into six level: h1 to h6, as h1 is the largest. All text contained within headng tags is displayed with bold font weight.

A Uniform Resource Locator (URL) is a type of URI which represents the network location of a resource such as a web page and so on. The URL consists of the protocol, the domain name and the hierarchical location of the file on the web server.

URL is the full address to a web page, e.g. https://www.edmodo.com/

There are different kinds of domain names. E.g. top-level domain, second-level domain and third-level domain.

A domain name is part of the URL. It locates an organization or other entity on the internet. The purpose of the Domain Name System (DNS) is to divide the Internet into logical groups and understandable names by identifying the exact address and type of the organization.

Domain name, e.g. Edmodo.com
