Nowadays, web development is essential in every domain. It allows sharing data and information with people on a large scale. For companies, it is now more important than it has ever been to have visibility on the net so they can promote their products and services, but also keep their customers close. Web development refers to the process of coding a website in a specific computer language. There are multiple languages to build a website like HTML/CSS, Javascript, PHP… but today we’ll tackle HTML/CSS and try to give a general idea of their utility.
HTML that stands for HyperText Markup Language and CSS for Cascading Style Sheets are closely related and complementary. We can’t use one without the other.
To clarify the difference between those two languages, we can suppose that HTML represents the hidden part of an iceberg and CSS the visible one. HTML was released in 1993. At that time more importance was given to information and data, CSS came out 3 years later to properly exhibit data graphically talking. Javascript makes the website content interactive and dynamic.
Let’s illustrate that with an example.
HTML :
<p> Hello ENCGHUB. </p>
CSS :
p {
font-size : 12px;
Color: red;
}
The result will be displayed this way:
Hello ENCGHUB.
HTML can run different types of content like texts, links, lists,forms, tables, media (pictures, audio, videos) or external integrations like video players for example.
CSS comes to properly visually display those types of content. CSS properties are text style, font character, text colour, background colour, alignment, zones, dimensions, opacity…
Using HTML/CSS allows :
-
-
- to define semantically correct content so search engines like google, yahoo and bing can read it !
- Visually display with CSS the content coded using HTML.
- To guarantee pages accessibility.
- To enhance the search engine optimization (SEO).
- To offer a pleasant user experience.
