Understanding how websites work is important, because without an understanding you would have a hard time debugging why certain parts or functionalities of a website may not be working.
Like a good coffee shop The web gives it to you while it’s hot Your device is the client The server provides without a drop. There’s no 25% tip to use TCP/IP, Just give that IP address a ping, and the CSS will com back squeeky clean.
The browser parses the HTML file first, and looks for links to CSS and Javascript. It sends requests back to the server for any CSS files it has found, and any Javascript. It generates a DOM tree from the HTML, the structure of the CSS, and compiles any Javascript. As the DOM tree is built, the CSS styles are applied, and the Javascript is executed. A visual representation of the page is painted to the screen which allows the user to see and interact with the website.
Finding assets and images is easiliy done by copying the link to the image/asset.
A sting is created using quotation marks. A number can be declared using the number without quotes.
A variable stores the placement of some data or value so that it can be referenced in your code.
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="utf-8" />
<title>My test page</title>
</head>
<body>
<p>This is my page</p>
</body>
</html>
Go inside the element
href="https://www.mozilla.org/"
Have an opening and closing tag
<a></a>
Together they make up use code
<a> href="https://www.mozilla.org/" </a>
An <article> encloses a block of related content that makes sense on it’s own (a blog post).
A <section> is for grouping together a part of a page that consittues one single piece of functionality, and should have a heading.
A typicle website will use semantic tags:
header: <header>.
navigation bar: <nav>.
main content: <main>, with various content subsections represented by <article>, <section>, and <div> elements.
sidebar: <aside>; often placed inside <main>.
footer: <footer>.
Search engines will use HTML tags to generate metadata so that a search engine knows what a page is about and can display approprate results to a user.
Metadata can be “officially” added to a website using the HTML tag. Metadata is used to describe additional information about a website and is good for optimoizing for SEO, adding a favicon, reading language correctly, etc.
Use the appropriate semantic element so that your website is readable and accessible to all
Add javascript to an HTML document by inserting the tag.
Use javascript for things like:
I’m so excited to begin to understand how APIs work and how I can send a request, and recieve a response from another server.
