- HTML and CSS are the languages we use to create web pages.
- Web servers store and serve Web pages, which are created from HTML and CSS.
- Browsers retrieve pages and render their content based on the HTML and CSS.
- HTML is an abbreviation for Hyper Text Markup Language and is used to structure your web page.
- CSS is an abbreviation for Cascading Style Sheets, and is used to control the presentation of your HTML.
- Using HTML we mark up content with tags to provide structure. We call matching tags, and their enclosed content, elements.
- An element is composed of three parts: an opening tag, content and a closing tag.
- There are a few elements, like <img>, that are an exception to this rule.
- Opening tags can have attributes. We have seen a couple: type and align.
- Closing tags have a “/” after the left angle bracket, in front of the tag name to distinguish them as closing tags.
- Your pages should always have an <html> element along with a <head> element and a <body> element.
- Information about the Web page goes into the <head> element.
- What you put into the <body> element is what you see in the browser.
- Most white space (tabs, returns, spaces) are ignored by the browser, but you can use these to make your HTML more readable (to you).
- CSS can be added to an HTML Web page by putting the CSS rules inside the <style> element. The <style> element should always be inside the <head> element.
- You specify the style characteristics of the elements in your HTML using CSS.
