HTML it’s quite simple language, it is studied by all students of technical and humanitarian specialties in higher education institutions, and the present moment think it study and at the majority of schools. The HTML language give sample opportunities for development of web pages and giving of attractive appearance to them, however thus a number of restrictions is imposed. The basic from them, which is directly concerning graphics — all objects placed on the page must to have a rectangular shape. Even if the image something roundish, it will be squared. This is caused by the reason, that in files can be written down only rectangular images. Some problems can arise during using special symbols, and also the symbols which aren't entering on the the basic (English) table of symbols. It is connected with that some symbols are service symbols (are used for needs of the language) or can't be correctly displayed without special instruction to the browser on what language were used by preparation of the document.
To unrecognizability it is possible to make "themization", that is to change the appearance of any html-code in Drupal template: all standard forms, blocks, documents and lists. Formatting of text part are carried out by means of the featured settings in style of a font, headings, tables, lists and other elements. There is a possibility of inclusion of the hyperlinks indicating the web page, the file or other object. As a matter of fact, this most important property of HTML allowing this language to be called as a hypertext markup language.
HTML Language has a wide choice of means of a task of appearance of the web page. On the web page can be placed any programs of user. Working with formatting of the page, each Drupal developer, which work with HTML code considers distinctions hardware and the software used by different users on different monitors with the different modes. Most important factor of influencing by sight pages is the browser, used by the user. The programs for viewing of web pages developed by different firms possess different opportunities and a set of functions. There is a situation in which the browser of the user won't be able to reproduce all your ideas correctly.
Distinctions between browsers are shown first of all in sets of the processed tags — the HTML features. There is a set of tags standardized by consortium WWW (W3) — the organization controlling development of the World Wide web. Software developers in principle have to follow recommendations and standards of consortium — it is necessary for maintenance of continuity and compatibility of programs and systems of different generations. But not all manage to execute precisely everything that demands the standard. Some coders often try to bring in HTML something new — new tags, parameters, functions. Sometimes such innovations are accepted by other producers and become the standard, sometimes they remain properties of the specific program.
Fortunately in CMF Drupal the cross browser specific is already considered. Developers shouldn't adjust it under each browser separately. But for every developer, which work with Html technology in Drupal and enter any changes really important to remember about cross browser specific.
Drupal is closely connected with the HTML technology, but our developers, have all necessary knowledge to work with any HTML code, change site by bringing improvements in functionality and appearance.
