The main tool for creating web pagesany level of complexity is the hypertext markup language or Hypertext Markup Language (HTML). All language constructs are called "HTML tags", which determine the display of text on the page and the layout of the entire html page.
Why use HTML tags?The fact is that any document that is available on the user's computer is created in any particular program, and for its discovery the vast majority of cases need exactly the program in which it was created, or the equivalent.
With the advent of the Internet, the question arose aboutthe correct transfer of documents between users' computers, each of which can have its own computer, a unique set of installed programs. Moreover, the platforms themselves may differ - not all computers connected to the Network are running Windows. Thus, the document received on the Web may well be inaccessible to a specific user.
In order for any document to be correctIt is recognized on any computer, regardless of the platform and package of installed programs, and the HTML hypertext markup language has been developed. In the body of the document, special constructions are introduced, called HTML tags, and the entire document is saved in plain text format, which is accessible to all computers.
The HTML language is not a programming languagein the usual sense. HTML tags only show a special browser program, how to display text on the page. The browser interprets the markup language constructs and displays the requested page.
Язык разметки гипертекста содержит самые разные tags that belong to different groups. One of the largest groups are HTML text formatting tags. They contain all the information about how the text itself should look: its alignment, size, spelling and font style, indents, lists, and also contains many other properties. The formatting of the text is indicated by the attributes of the tags and entered into the tags. It should be borne in mind, however, that modern technologies for creating web pages rendering all the text formatting and displaying the whole page in a separate cascading style table file, attributes that can contain HTML text formatting tags are rarely used now.
The reasons for this phenomenon are that the use ofin the web design of cascading style sheets (SCC) in the creation of sites is very convenient. It is enough just to put all the design in the CSS file and connect to it all the pages of the site (or some). Such pages will always look the same. If you need to make changes to the design of certain elements of the page (heading of the second level, for example), it is enough to change only one entry in the CSS file. All headings of the second level (h2) on all pages connected to CSS will change. In particular, to make the headings green, it is enough to write only one line in the CSS file:
h2 {font-color: green}
And this is how a paragraph will be defined, aligned to the right, on a red background, with a blue text:
p {background-color: red; color: blue; text-alignment: right}
All HTML tag cloud contains a lotdesigns, but their study, as well as the study of the peculiarities of their use, seems absolutely necessary for a web designer, and especially for the layout designer, who without them will not be able to impose a page.
In addition, one should always bear in mind that inlately there has been an obvious division into "areas", which had not existed before, as there was no separate existence of layout, design and program part of web pages.
When creating serious sites,technologies, somewhat different from the traditional programs included in the package of office documents. Even for creating a simple web page, html tags are used.
