HTML is a “web” page presented as a file. In other words, this is a kind of file extension, as well as a markup language used on the World Wide Web.

With its help, we can not only view the content of sites, but also create “web” pages.

The language itself was created by an English scientist named Tim Berners-Lee. Its development was carried out in Geneva in the building of the European Center for Nuclear Research, around 1986 - 1991. Initially, HTML was supposed to be a language that would allow the exchange of technical and scientific documentation among ordinary people (that is, those who are not any specialists in the field of design layout). However, later, it became the basis for the “life” of the Internet.

HTML is a tagged markup language, thanks to which the average user can create a relatively simple, but at the same time beautifully designed document.

How to open a html file. Instructions.

Method number 1. Using a text editor.

If you need to make any changes to a file of this format, you need to open it using a text editor. This can be done using the standard Notepad program. But it is best to use the Notepad++ program. It allows you to quickly find the required “piece” of code, highlights syntax, is intuitive, and so on.

1. Before opening the html extension file, you need to download this program and then install it.

2. Now right-click on the desired file, hover over the “Open with” option and select “Notepad++”. (If the program is located in the main menu, as shown in, then clicking on the “Open with” item is not necessary).

3. A window with a “code” will open in front of you, which you can now edit.

Method number 2. Using a web browser.

If you just want to view the file you downloaded/created, then . Moreover, it can be anything, be it Opera, Mozilla or Chrome.

Double-click on your file with the left mouse button. If nothing happens, then right-click on it and select the “Open with” option. Then select the required (most frequently used) browser from the pop-up menu.

In these simple ways you can both edit and open your html files.

The most common problem that prevents users from opening this file is an incorrectly assigned program. To fix this in Windows OS, you need to right-click on the file, in the context menu, hover the mouse over the “Open with” item, and select “Select a program...” from the drop-down menu. As a result, you will see a list of installed programs on your computer, and you can select the appropriate one. We also recommend checking the box next to “Use this application for all HTM files.”

Another problem that our users also encounter quite often is that the HTM file is corrupted. This situation can arise in many cases. For example: the file was downloaded incompletely as a result of a server error, the file was damaged initially, etc. To resolve this problem, use one of the recommendations:

• Try finding the file you need in another source on the Internet. You may have luck finding a more suitable version. Example Google search: "File filetype:HTM" . Just replace the word "file" with the name you want;
• Ask them to send you the original file again, it may have been damaged during transmission;

Nowadays, any web programmer can confidently answer the question: HTML - what is this extension? But not everyone is a web programmer. Surely there are people who are not yet ready to give the correct answer to such a question. Therefore, let's look at the concepts related to this, so to speak, from the beginning.

HTML - what is it?

HTML (Hypertext Markup Language) is a common language for marking up Internet documents (not a programming language!). Almost all web pages are created using it. The latter differ from ordinary documents containing text and other elements (images, tables) in that they contain special descriptors (tags) that are necessary for the text to be understandable by any browser. The HTML extension (or HTM) is a sign that the file belongs to the category of web documents.

HTML tags are special instructions that contain information about the structure and formatting of a web page. Each tag is included in the text inside angle brackets<>. Almost all tags are paired and contain an opening and closing part, affecting the text inserted within these parts.

Examples of using HTML tags can be seen by opening any web page in Tag View. To do this, in the browser menu you need to select the “View” - “As HTML” item. For some browsers, hotkeys also work: Ctrl + U, when pressed in a separate browser tab, the same page opens in a mode that allows you to see HTML codes.

From the history of markup language standards

There are different versions of HTML. The language is constantly being improved, so a new version is released almost every year. Different web browsers (programs for viewing HTML pages) are developed by different companies and differ in the interpretation of individual tags and their support. As a result, the same HTML code is displayed differently by different browsers, and some browsers do not understand individual tags at all.

Before 1990, hardly anyone in the world would have correctly answered the question: HTML - what is it? Documentation for this language was first published in 1991. The author, physicist Tim Berners-Lee, came up with it as a tool that allows you to turn a set of characters transmitted over the network into headings, links and paragraphs. It soon became the standard language for marking up documents on the Internet.

In its development, it has gone from the initial edition to HTML 5 and continues to improve. This language contains descriptors for both structure and formatting. Subsequently, standard CSS technology was adopted, which involves separating the formatting description into a separate CSS file, leaving the description of the document structure for HTML tags. As a result, some descriptors were no longer used.

HTML Document Structure

It is clearly regulated and must contain several mandatory tags. These include:

• Tag- type of document and its characteristics.
• Tags - indicate the starting and ending boundaries of the document.
• Tags - limit the service section of the document, which contains instructions for browsers, search robots, as well as links to files and scripts.
• Tags - to enter instructions to browsers and search robots.
• Tags - set the main title of the document; it is visible only in the top tab of the browser window.
• Tags - limit the visible part of the document.

Tags that are useful to know

The functions of commonly used tags should be understandable to any copywriter; adding them to the text is possible in any text editor. They can be used when formatting text without having a special editor at hand. The following HTML codes, in particular, are commonly used:

• - to highlight a paragraph.
• 
  text
  - to wrap text to the next line.
• highlighting in bold - to highlight in bold.
• in words-to highlight text in words.
• anchor - to insert any anchor - a word or object that initiates a transition to the link specified in the tag. Instead of the word "anchor" write "HERE" or enter any other word, phrase, object; Instead of the word “link”, insert the Internet address where the link leads.

• Heading

  - to highlight the first level heading.

• Subtitle

  - the same for the 2nd level heading, etc. up to the sixth level.

How to create an HTML file in a regular editor

A web page (that is, an HTML file) can be typed in any text editor (for example, Notepad). But all tags will have to be entered manually. The advantage of this method is the absolutely minimized code. Disadvantages - requires good knowledge of hypertext markup language and the inability to immediately see the results of your work. Therefore, this method is only suitable for creating very simple web pages.

HTML editors

Almost all specialists use special HTML editors. The most popular of them are Macromedia HomeSite and Dreamweaver MX. They allow you to automatically enter many tags, highlight text and service code elements, and immediately view the result in a special window. But these programs are paid.

For a beginner, it is better to first test your skills using freely distributed editors. The most popular of them include Notepad++, Komodo Edit, Aptana, Alaborn iStyle and KompoZer. Each of these programs has its own advantages, provides the user with greater or lesser functionality, and has its own interface. To choose the one that suits you, you need to try working in each of them. This is easy to do because you don't have to pay to try.

In addition to these editor programs, there are visual design tools (for example, HoTMetal Pro). When creating web pages, they completely eliminate the need to manually enter HTML descriptors. However, such programs produce excessively redundant code, the amount of which significantly exceeds the required minimum size. In addition, manual editing of the code is often required to bring it to the desired quality.

Familiarization with the material in this article, we hope, will allow even a novice user to have no doubt about the answer to the question: HTML - what is it?

The most common cause of problems with opening the HTM file is simply the lack of appropriate applications installed on your computer. In this case, it is enough to find, download and install an application that serves files in the HTM format - such programs are available below.

Clue

Please note that some encoded data from files that our computer does not read can sometimes be viewed in Notepad. In this way we will read fragments of text or numbers - It is worth checking whether this method also works in the case of HTM files.

What to do if the application from the list has already been installed?

Often an installed application should automatically link to an HTM file. If this does not happen, then the HTM file can be successfully linked manually with the newly installed application. Simply right-click on the HTM file, and then from the available ones select the "Choose default program" option. Then you need to select the “View” option and find your favorite application. The entered changes must be approved using the "OK" option.

Programs that open the HTM file

Windows

Mac OS

Linux

Why can't I open the HTM file?

Problems with HTM files can also have other causes. Sometimes even installing software on your computer that supports HTM files will not solve the problem. The reason for the inability to open and work with the HTM file may also be:

Inappropriate HTM file associations in registry entries
- corruption of the HTM file we open
- HTM file infection (viruses)
- too little computer resource
- outdated drivers
- removing the HTM extension from the Windows registry
- incomplete installation of a program that supports the HTM extension

Fixing these issues should result in freely opening and working with HTM files. In case your computer still has problems with files, you need to take the help of an expert who will determine the exact cause.

My computer does not show file extensions, what should I do?

In standard Windows system settings, the computer user does not see the HTM file extension. This can be successfully changed in the settings. Just go to the "Control Panel" and select "View and Personalization". Then you need to go to "Folder Options" and open "View". In the "View" tab there is an option "Hide extensions of known file types" - you must select this option and confirm the operation by clicking the "OK" button. At this point, the extensions of all files, including HTM, should appear sorted by file name.

The htm format, invented more than twenty years ago, is a language for developing web documents. In this format not only websites can be created, but also music collections, books, etc.

Many people are interested in the difference between htm and . Previously, they did have some differences - html was used on Unix systems, and htm was supported on Windows. Today they are no different and work according to the same scheme.

What program to open the HTM file

First of all, you can open the htm file in: Firefox, IE, Opera (on Windows), Apple Safari (for Mac OS), etc.

If you have Windows, then development applications such as Microsoft Visual Studio 2010 and Adobe ExtendScript are suitable. For Mac OS, Adobe GoLive and Adobe Creative Suite for Mac are used. In addition, there is a cross-platform Adobe ColdFusion Builder 2 program.

If you choose how to open an htm file for editing, choose, even the simplest of them allow you to edit and save htm content.

Accordingly, if you use Linux, then Opera for Linux or Firefox for Linux, Konqueror (browser), text editor gedit or GNU Emacs will be useful to you.

How to edit HTM files conveniently

So, we can edit the file both in Notepad and in special development applications, for example in Visual Studio 2010. However, in the second case it will be much more convenient, since in Notepad all tags will have to be entered manually. In addition, some programs do not have special highlighting, and reading the code will be very inconvenient. If you use a special application, then due to its intelligent functions it will itself offer you various tag options and tell you that you forgot to put a closing tag if this happens.

If you created an HTM file, do not forget to save it using the htm extension.

The file should immediately open in the browser as a web page. If you click on the file, but it does not open, then go to the browser, click on the “Open” item, specify the path to the document.

So, in this review, we briefly looked at what it is and how to open an htm file, as well as features that should be taken into account in order to make working with this format more convenient. The advantage of this extension is its versatility - many programs allow you to view such documents.
