CSS basic concepts How to make the web pages have the look we want, with the colors the edges and the types of letters and backgrounds that we want, To make a web page look more professional and more efficient, it is necessary to use the following technology that technology is known as CSS - CASCANDING STYLE SHEETS, there are different levels of css each level of css is built adding functions at a previous level. I advise you that if you want to learn CSS 2.1, so all current browsers are supported CSS3 has very interesting news, but it is currently under development and not all navigators support it. CSS is a very simple language that is composed of rules, each rule is formed by one or more selectors and a statement formed by a block of styles that define the styles to apply. In this example the html element is h1 so this rule it will be applied to all the level one users of the website. Each style declaration is defined between braces {} and is made up of pairs property .valor. Since the css language was released in 1996 the number of properties it has been increasing and currently has more than 200 properties. As happens with the html the css language is also developed by w3c the international agency that ensures the correct development of the web, on this w3c page you can check the official specification of the css.

But to start learning is not recommended since this is a site for experts I advise you to use the w3cshools, here you will find the tutorial of css plus the reference guide in which you will find all the properties of css grouped in different groups besides I encourage you to consult the article prepared by the wikipedia and I also recommend that you see the css training that is a css learning course that is organized in 4 weeks with learning topics that you start in week one and you have a term in week 4. important note : With HTML only the structure and content of the web pages are defined. In order to achieve that the web pages have the visual presentation that we want, that is to say, colors, type and size of letter, etc., it is necessary to use an additional technology. That technology is CSS, Cascading Style Sheets. CSS is a language that is made up of rules. Each rule is formed by one or more selectors, and a statement formed by a block of styles that defines the styles to apply for the elements of the document that comply with the selector. Each declaration of styles is defined between braces and is formed by couples Property, Value. Couples present themselves in the form Property: Value. I hope this helps them a lot on the way to their learning of programming css
