People who design web pages relatively short, or just do not feel this good, it will find the information and sometimes do not go in the wrong direction.
HTMLHTML is used to create the skeleton - the logical layer (header, menu, footer, content, paragraph, etc.) - should not be used to shape the appearance of the HTML page, the background color, font, size anything (blocks of text, fonts, header etc). It is a knock once and for all: HTML is responsible for distributing the content into logical sections.
CSSCascading Style Sheets, or CSS are used to shape the look of our website. So we created using skeleton HTML page (header, menu, block the main text, footer, etc) and now using CSS, we can have an impact on the appearance of these elements, the size, margins, alignment (relations between) the color, etc. CSS can written (in fact we should do so) to an external file. Pointing to using CSS to specific elements of HTML tags is done by class (class = "name") and identifiers (id = "name").
HTML and CSS is used to make static pages. If you want to have a dynamic page (CMS, forum, portal, etc.) comes to us with the help of PHP.
PHPPHP is a programming language similar to C / C + + server-side (or on our hosting). By. me is quite simple, simpler than C / C + + (because its syntax is much simpler, such as the lack of variable declarations, and has a very substantial base built-in functions), some argue that by this simplification easier to program and easier to make mistakes - perhaps this is true, I find it hard to assess (rather encodes only in PHP).
Why do we need it PHP? If you want to create a dynamic page, then just write a script in PHP that such "sticky" We header, menu, content and footer. Depending on your choice from the menu script doklei us the right content to the header and footer menu. It's a simple example.
It is worth noting (for those green especially) that the PHP on the server generates HTML and sends it to the browser. So you can not preview a PHP page, we'll see only the effect of this script, which said generated HTML. In addition, application of this begs the obvious - PHP is an HTML generator, therefore, does not in itself be used to create pages and to make use of it you need to know HTML.
MySQLMySQL is a type of SQL database - one of the most popular (eg FOR IN zemnie used ;)). The database comes to our aid if we are a fairly comprehensive site that is growing all the time - comes its content. So it is such a forum, website, blog, etc. MySQL is based on SQL queries (like MS Access). All MySQL data can be represented precisely in these queries. But the base itself will not help us. To use MySQL you must also use PHP. Using PHP to connect to our database, we send the request (eg, "Get a list of userów" - "SELECT * FROM tabela_userzy ') charge response in the form of a PHP array and do this on what we want, for example, list the userów) .
Nowadays, web development is very fast and HTML itself is not enough. Increasingly, it is necessary to connect HTML + CSS + PHP + MySQL. But there is
This is just a small example. But the JS in conjunction with other languages can be a powerful tool for adding high interactivity on the site and reduces the load on the server (eg, AJAX).
