+<h1>HTML Basics</h1>
+<p>I know that:
+	<ul>
+		<li>inline styles override all others.</li>
+		<li>index.html is one of the industry standard default file names, as well as index.htm, index.php, index.asp, index.aspx and more.</li>
+		<li>iframes are used to embed documents within other documents.</p>
+		<li>
+			CSS files are linked by using the following code:
+			<br>
+			<code>&lt;link rel="stylesheet" type="text/css" href="../css/main.css"&gt;</code>
+		</li>
+		<li>
+			JS files are linked by using the following code:
+			<br>
+			<code>&lt;script type="text/javascript" src="scripts/scripts.js"&gt;&lt;/script&gt;</code>
+		</li>
+		<li>
+			Adding the date when the window loads:
+			<br>
+			<code>
+				// onload of window
+				<br>
+				window.onload = dateInsert;
+			</code>
+		</li>
+		<li>
+			Ternary operators work by using:
+			<br>
+			<code>[condition] ? [value if true] : [value if false]</code>
+		</li>
+		<li>The later a CSS file is imported, the more power it has over the document - i.e. the last stylesheet imported will overwrite the styling in all of the other stylesheets.</li>
+		<li>To add another page, one can use an <code>&lt;iframe&gt;</code> or the jQuery <code>.load()</code> method.</li>
+	</ul>

+		<h2>Cookies</h2>
+		<p>
+			Cookies are not, unfortunately, the treats made of dough. They are, in fact, small text files, stored in binary, usually one-line long, which store relevant
+			information about websites visited by a computer. This might include a selected language, or ad preferences. Some websites even use
+			cookies to store passwords that are set to ‘remember’. Thus, cookies need strong security and the ID of each one must be unfathomably
+			difficult to find without permission, to reduce the risk of hacking. Cookies are stored on the computer, as opposed to the website.
+			Because both HTTP and HTTPS don't transmit user data, none of the websites you visit know who you are. Therefore, whenever you
+			visit a webpage, it reads the cookies it stored on your computer last time you visited it, in order to find out information like your email address.
+			Many people are against cookies, due to privacy concerns; under new GDPR regulations, all end users in Europe must now be notified of
+			cookie use on each website they visit (if the website uses cookies). Many sites also give an option to refuse cookies.

+        <h2>CSS</h2>
+        <p>
+            CSS, Cascading Style Sheets, are web documents that allow stylisation of HTML documents. CSS allows you to change the size, style, font, and colour of text; margins and padding; background colours and border styles. To change the appearance of something in CSS, there must be the following format:
+            h1 {
+            Background-color: red;
+            }
+            which would make the background colour of heading 1 tags (big headings) red. The spellings in CSS are American, for example color, and semicolons are extremely important. The following hyperlink has a list of all the CSS commands and what they do when you click on them.
+
+
+            Cascading Stylesheets (CSS) allow the size, style, font & colour of text; background colours & border styles and more to be changed in HTML pages.
+            A page without CSS can be very bland and boring:
+            <br>
+            <img class="presentation-image" src="../images/without_css.jpg">
+            <br>
+            But one with CSS looks a lot more presentable:
+            <br>
+            <img class="presentation-image" src="../images/with_css.jpg">
+            <br>
+            CSS declarations use the <i>tag names</i> (e.g. <code>p</code>), <i>classes</i> and IDs of
+            the elements on the page in order to style them. IDs are written with a preceding hashtag,
+            classes are written with a preceding full stop and tag names are written without any preceding characters.
+            The styles themselves (like <code>height</code>) should all end in semicolons. A comment in CSS is started
+            with <code>/*</code> and ended with <code>*/</code>.
+            Here are some example declarations:
+            <br>
+            <code>
+                p {<br>
+                    /* this changes the font size of all p elements */<br>
+                    &nbsp;&nbsp;&nbsp;&nbsp;font-size: 3rem;<br>
+                }<br>
+                .class_name {<br>
+                    /* this changes the height of all elements with the class name 'class_name' */<br>
+                    &nbsp;&nbsp;&nbsp;&nbsp;height: 200px;<br>
+                }<br>
+                #id_name {<br>
+                    /* this changes the font of all elements with the ID 'id_name' */<br>
+                    &nbsp;&nbsp;&nbsp;&nbsp;font-family: 'Roboto'<br>
+                }<br>
+            </code>
+            <br>

+        <h2>HTML</h2>
+        <p>
+            Hypertext Markup Language is the standard language used by browsers to display webpages.
+            HTML was invented by Tim Berners-Lee in 1990, and uses tags. This means that in order to define
+            an element (something like a heading or paragraph), you use a <i>tag</i> - such as <code>&lt;p&gt;</code>,
+            which displays a simple paragraph. Most tags must be closed with closing tags - like <code>&lt;/p&gt;</code>,
+            however some elements, like those for images (<code>&lt;img&gt;</code>) and linking external resources
+            (<code>&lt;link&gt;</code>) are auto closing: they don’t need a closing tag. For example, an image is defined as follows:
+            <br>
+            <code>&lt;img src="image_source_url"&gt;</code>
+            <br>
+            A comment in HTML is started with <code>&lt;!--</code> and ended with <code>--&gt;</code>.
+            <br>
+            HTML is closely linked with CSS and JavaScript.
+        </p>

+		<h2>HTTP</h2>
+		<p>
+			HTTP is Hypertext Transfer (or Transport) Protocol, the underlying data transfer protocol used on the World Wide Web. It defines what actions web servers and browsers should take in response to commands. For example, when a URL is opened or hyperlink (which is a URL) clicked, your web browser actually sends an HTTP request to the server which hosts the website you're trying to access, in order to fetch it and display it on your screen. Obviously, for each web server to understand these requests, the server and request must both follow this protocol.

+			(TLS) - an encryption protocol invoked by an HTTPS request, that enables authentication and encryption on the webpage being visited. SSL is
+			essentially the usage of ‘digital passports’, and it functions by ‘hopping onto’ TCP protocols. It does not resend ‘lost’ packets or
+			‘miscommunicated' data, because this increases security.

+		<h2>Hyperlinks</h2>
+		<p>
+			A hyperlink is simply a link on the web to another resource. It uses a special kind of command that jumps you to different content in your web browser - usually to another page. 
+			<br>
+			Hyperlinks are often denoted by blue underlined text or content which turns the cursor into a pointing hand when hovered over; however, they can be styled however the web designer wishes; their appearances do not change their function.
+			<br>
+			Website owners reserve the right not to be hyperlinked without permission.
+			<br>
+			Hyperlinks are defined in HTML as follows:
+			<code>&lt;a href="LINK GOES HERE"&gt;TEXT GOES HERE&lt;/a&gt;</code>

+        <h2>JavaScript</h2>
+        <p>
+            JavaScript (JS) is a high-level, client-side language, meaning that it is like a human language
+            (rather than, for example, binary) and runs on the end user's computer. It is used for many purposes,
+            including editing content on a webpage, performing mathematical operations and storing variables.
+            Each line of JavaScript should end in a semicolon, for example:
+            <br>
+            <code>
+                // this code sets the content of the element with the ID "id_name" to "Hello World!"<br>
+                document.getElementById("id_name").innerHTML = "Hello World!";
+            </code>
+            <br>
+            A single line comment in JS is denoted by a double forward slash (<code>//</code>); a multi line comment
+            is started with <code>/*</code> and ended with <code>*/</code>.
+        </p>
