Part 1: HTML
HTML (Hypertext Markup Language) is the foundation of the web. So it’s the markup language use to create the structure and content of web pages. HTML is a relatively simple language that consists of tags and attributes, which are use to define different elements of a web page.
Here are some of the key elements you’ll need to know when working with HTML:
- Headings: Headings are use to structure the content of a web page. There are six levels of headings, from H1 (the most important) to H6 (the least important).
- Paragraphs: Paragraphs are use to group together blocks of text. They’re defined using the
- Links: Links allow users to navigate between different web pages. They’re defined using the
<a>tag, and can include attributes like
hrefto specify the target page.
- Images: Images are use to add visual content to a web page. So they’re defined using the
<img>tag, and include attributes like
srcto specify the image file.
- Lists: Lists are use to group together related items, either in an ordered (numbered) or unordered (bulleted) format.
- Forms: Forms allow users to input data into a web page, and can be use for things like registration, login, and search. They’re defined using the
<form>tag, and can include various input fields like text boxes and checkboxes.
Part 2: CSS
CSS (Cascading Style Sheets) is use to style the visual appearance of a web page. So It allows you to control everything from the color and font of text, to the layout and positioning of different elements. CSS is written in a separate file from the HTML, and is linked to the HTML using the
Here are some of the key concepts you’ll need to know when working with CSS:
- Selectors: Selectors are use to target specific HTML elements and apply styles to them. You can use selectors like
#idto target different types of elements.
- Properties: Properties are used to define specific styles for an element, like
background-image. So you can set multiple properties for an element by separating them with semicolons.
- Units: Units are used to specify measurements for different styles, like
em(based on font size), and
%(percentage of parent element).
- Box model: The box model is a way of conceptualizing the layout of an HTML element. So it includes the content area, padding, border, and margin.
- Layout: CSS can be use to control the layout of a web page, including the positioning and size of different elements. Techniques like flexbox and grid can be use to create more complex layouts.
