What is a web page, how is it created and loaded? What should I do if the page is not available?

Every user of the worldwide network is familiarwith the term "site". This is an online resource that has its own address, name, owner and consists of a large (or not) number of web pages. They contain all the information that the creator or owner of the site wants to share with other users-visitors. It can be texts, pictures, audio and video files, as well as links to other data, etc. In the development of the entire site and each of its separate pages, experts from different fields take part: designers, copywriters, layout designers, programmers. As a result of their joint work, we get what we eventually see when we enter one or the other address in the address bar. However, people who do not have specific knowledge of how the Internet works and works do not fully understand what a web page is and how it is formed, functions, and loads. In this article, we will try to talk about this in an accessible and understandable language.

How does the web page start?

What are the stages of the process of creating a website page? In order to understand what a web page is, you need to understand how it is formed.

Design

Everything starts with the work of the designer. He, in accordance with the requirements and objectives of the customer, develops a layout of the future site. This layout is created for one, two or more pages. At this stage, the location of all necessary objects is determined, the selection of fonts, pictures, design in general. That is, initially the appearance of the pages is formed, from which a full-fledged site will be assembled.

Nesting

Then the coder is included in the work. Based on the layout developed by the designer, he makes the layout of the page, optimizing it for different browsers. To do this, create a normal document, for example, in "Notepad", which is saved with the extension. Html. It is in this language that a simple web page is written. HTML stands for HyperText Markup Language and is a set of tags that serve to implement a variety of tasks. This language is simple enough, but functional. With its help, a logical structure of the page is created and it is divided into separate elements - headings, lists, paragraphs, tables and other objects. In addition, tags determine the meaning of all content. They give the browser information about what to highlight, emphasize where to step back, where to insert a picture, and what to convert to a link. As a result, the page gets the appropriate view. However, to make it completely consistent with what the designer came up with, you also need to use CSS. These are cascading style sheets that specify the appearance of an html document, its appearance. With the help of CSS-tools you can "paint" the page in the right colors, apply this or that font style, add other design elements. Using HTML and CSS gives us a ready, beautifully designed page. But she still needs to give dynamism, and this is the programmer's business.

Programming

At this stage, you have already formedAn understanding of what a web page is and how it is created. However, that's not all. Pages are of several types - static, dynamic and interactive. The first ones relate to those that are created only using html and css. In order to make the page dynamic, you need the engine - CMS (or Content Managment System). This is a special program that generates a page from the data stored in the server database upon user requests. That is, the page is created when the request is received from the user. For its writing, languages ​​such as ASP, PHP, and others are used. As for the interactive pages, they include the so-called forms, through which the user and the server communicate. They are also written in the languages ​​of PHP, JavaScript, etc. Programming is a more complex process than layout, it requires qualitative specific knowledge of at least one (and better than several) of the listed languages.

How does the web page load?

To make the page available to everyoneusers of the Internet, its (that is, the document in which it is described) is placed on the web server. This is a computer that continuously works in anticipation of requests from browsers. When it receives it, it finds the requested resource (for example, a web page) and sends it to the appropriate browser. And the latter, in turn, displays a web page based on the information (signals) contained in the document.

Why can not I open a web page?

There are times when you enter a query(specify the address, write the word in the search box or click on the link), but the browser can not display the information you need and writes that the web page is not found. What is the reason and how to solve this problem?

First, you should check the url-address -whether it is specified correctly. If there is an error in some letter or sign, then the server will not be able to find the information adequate to your request, and the browser, respectively, display it. But if the address is correct, then why is the web page not available? The reason may be cookies. They are created by the web pages that you visited earlier, for storing some settings and other things. If such a file is corrupted, this may prevent normal page loading. To fix the situation, you need to delete it. To do this, in the browser settings, find the "Privacy" section, go to the content settings and select "All cookies and site data" in the window that opens. Click "Delete All."

The third reason may be slow workbrowser in connection with the use of a proxy server. To fix the problem, you need to change the settings. You can do this in the "Connections to the Internet" section. Select the network you are using, open the settings and look for the "Proxy" tab. Set the desired settings for its use. Now everything should work.

Conclusion

From this article, you learned about what isa web page, how it is formed and which specialists are involved in its creation. We also looked at how the site pages are loaded and displayed, why they might not open, and how to solve this problem. Now you know a little more about how the Internet functions and what its Web resources are.
