Today, we begin our journey into web development by discussing HTML. Who can tell me what HTML stands for?
HyperText Markup Language!
Exactly! HTML structures our web content using various tags. Can anyone share how we might display a title on a webpage?
We would use heading tags, like `<h1>`.
Correct! Remember, headings range from `<h1>` to `<h6>`. A simple mnemonic to help you remember is 'High to Low - Headings Show'. Let's look at a basic HTML structure next.
What does the `<!DOCTYPE html>` line mean?
Great question! This declaration tells the browser to expect HTML5. Let's recap: HTML gives structure, tags define elements, and we use headings for hierarchy. Keep these in mind as we move forward!

Now, let's shift our focus to CSS. What do you think CSS does in relation to HTML?
It styles the webpage!
Exactly! CSS stands for Cascading Style Sheets. It allows us to control everything from colors to layout. Can someone give me an example of how we might change text color?
We could use a rule like `p { color: blue; }`.
Spot on! Another memory aid is to think 'CSS for Color, Style, and Structure.' Next, let's discuss the different ways to apply CSS to our HTML.
Isn't it possible to use inline, internal, and external CSS?
Exactly! When using external CSS, it's best for larger projects. It keeps your HTML clean. Remember: Separation leads to better organization.

Let's explore some essential HTML elements. Can anyone tell me about the significance of lists in HTML?
They help organize information, right?
Especially true! We can use ordered lists with `<ol>` and unordered lists with `<ul>`. Any examples of list items?
Steps for making a sandwich can be listed.
Good example! Now, when it comes to CSS selectors, what's the difference between class and ID selectors?
Class selectors can style multiple elements, but IDs are unique to one element.
Right, and remember, for classes, we use a dot prefix, while IDs use a hash. Let's summarize today's points before moving on. We learned about the structure of HTML elements, how to create lists, and the importance of selectors in CSS.

Front-End Essentials (HTML, CSS)
This section covers the essential technologies for front-end web development, primarily focusing on HTML and CSS.
HTML (HyperText Markup Language) is the backbone of any webpage. It structures content using elements defined by tags, such as <h1> for headings and <p> for paragraphs. Attributes within these tags provide additional functionality, like the href in <a> tags for creating hyperlinks.
CSS (Cascading Style Sheets) complements HTML by defining the visual aspects of a web page, including colors, fonts, and layout. CSS rules can be applied inline, internally within a page, or externally through separate files. This section breaks down common HTML elements, CSS properties, selectors, and their best practices in web design. By mastering these tools, learners gain the ability to create complete web pages that are both functional and visually attractive.
