Basics of HTML, CSS & JS

“I think im finally understanding all of this”- Mikey, A Codefellows Student

what ive learned: HTML & CSS

chapter 2: Text (pp.40-61)

• HTML has six “levels” of headings, Browsers display the contents of headings at different sizes.
• By default, a browser will show each paragraph on a new line
• By enclosing words in the tags < b> and < /b> we can make characters appear bold. < i> will make them italic.
• When the browser comes across two or more spaces next to each other, it only displays one space.
• if you wanted to add a line break inside the middle of a paragraph you can use the line break tag < br/> To create a break between themes < hr />
• < strong> element indicates that its content has strong importance.
• If you use an abbreviation or an acronym, then the < abbr> The < blockquote> element is used for longer quotes that take up an entire paragraph

  Chapter 10: Intro CSS (pp.226-245)

• Block level elements look like they start on a new line.
• inline elements flow within the text and do not start on a new
• Selectors indicate which element the rule applies to.
• Declarations indicate how the elements referred to in the selector should be styled
• CSS declarations sit inside curly brackets and each is made up of two parts: a property and a value,
• You can also include CSS rules within an HTML page by placing them inside a < style>
• If the two selectors are identical, the latter of the two will take precedence.

• Javascrpit

• Its always best to keep JS code in its own file and foled with a.js extension
• js always activates where its called in html
• a script is a series of instructions a computer follows one by one
• js is case sensitive
• you should always write comments to explain what your code does or what you are trying to acheieve
