What is HTML and CSS? In 1989, Tim Berners-Lee invented the Web with HTML as its publishing language. HTML (HyperText Markup Language) was created to help programmers describe the content on a website like <this is a heading>, <this is a paragraph>. HTML uses tags to help you add paragraphs, headers, pictures, bullets, and other pieces of structure. Just like you would write something on a word document, HTML helps you write something on a website. CSS was first proposed by Hakom Lie and co-created by Bert Bos around 1996. Created to complement HTML, CSS (Cascading Style Sheets) is what makes a website look and feel amazing. Presentation and ease of use have been some of the qualities CSS has brought to web development. It is more involved with changing a website's style rather than its content. Kind of like changing the font size, font color, and positioning on a word document. CSS is in charge of the way the content looks on a page and what else goes on it to compliment that content. Why we need CSS? For example, CSS can be used to define the cell padding of table cells, the style, thickness, and color of a table's border, and the padding around images or other objects. CSS gives Web developers more exact control over how Web pages will look than HTML does.
