HTML Frames

Frame setting in html

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The HTML element defines a particular area in which another HTML document can be displayed. A frame should be used within a .

Using the element is not encouraged because of certain disadvantages such as performance problems and lack of accessibility for users with screen readers. Instead of the element, may be preferred.

Attributes

Like all other HTML elements, this element supports the global attributes.

This attribute specifies the document that will be displayed by the frame.

This attribute is used for labeling frames. Without labeling, every link will open in the frame that it’s in – the closest parent frame. See the target attribute for more information.

This attribute prevents resizing of frames by users.

This attribute defines the existence of a scrollbar. If this attribute is not used, the browser adds a scrollbar when necessary. There are two choices: «yes» for forcing a scrollbar even when it is not necessary and «no» for forcing no scrollbar even when it is necessary.

This attribute defines the height of the margin between frames.

This attribute defines the width of the margin between frames.

This attribute allows you to specify a frame’s border.

Example

A frameset document

doctype html> html lang="en-US"> head> head> frameset cols="400, 500"> frame src="https://developer.mozilla.org/en/HTML/Element/iframe" /> frame src="https://developer.mozilla.org/en/HTML/Element/frame" /> frameset> html> 

If you want to embed another HTML page into the of a document, use an element.

Frame setting in html

Определяет структуру фреймов на веб-странице. Фреймы разделяют окно браузера на отдельные области, расположенные вплотную друг к другу. В каждую из таких областей загружается самостоятельная веб-страница определяемая с помощью тега . С помощью фреймов веб-страница делится на два или более документа, которые обычно содержат навигацию по сайту и его контент. Механизм фреймов позволяет открывать документ в одном фрейме, по ссылке, нажатой в совершенно другом фрейме. Тег заменяет собой элемент на веб-странице. Допустимо использовать вложенную структуру элементов, это позволяет разбить один фрейм на две и более области.

При использовании фреймов примите во внимание их следующие особенности.

• Поисковые системы плохо работают с фреймовой структурой, поскольку на страницах, которые содержат контент, обычно нет ссылок на другие документы.
• Фреймы скрывают адрес страницы на которой находится посетитель и устанавливаемый через тег , и всегда показывают только адрес сайта. По этой причине понравившуюся страницу невозможно поместить в раздел «Избранное» браузера.
• Пользователь зачастую оказывается на сайте, совершенно не представляя, куда он попал, потому что всего лишь нажал на ссылку, полученную в поисковой системе. Чтобы посетителю сайта было проще разобраться, где он находится, на каждую страницу помещают название сайта, заголовок страницы и навигацию. Фреймы, как правило, нарушают данный принцип, отделяя заголовок сайта от содержания, а навигацию от контента. Представьте, что вы нашли подходящую ссылку в поисковой системе, нажимаете на нее, а в итоге открывается документ без названия и навигации. Чтобы понять, где мы находимся или посмотреть другие материалы, придется редактировать путь в адресной строке, что в любом случае доставляет неудобство.
• Большое число фреймов требует для браузера выделения больше памяти, чем обычно.

HTML — Frames

HTML frames are used to divide your browser window into multiple sections where each section can load a separate HTML document. A collection of frames in the browser window is known as a frameset. The window is divided into frames in a similar way the tables are organized: into rows and columns.

Disadvantages of Frames

There are few drawbacks with using frames, so it’s never recommended to use frames in your webpages −

• Some smaller devices cannot cope with frames often because their screen is not big enough to be divided up.
• Sometimes your page will be displayed differently on different computers due to different screen resolution.
• The browser’s back button might not work as the user hopes.
• There are still few browsers that do not support frame technology.

Creating Frames

To use frames on a page we use tag instead of tag. The tag defines, how to divide the window into frames. The rows attribute of tag defines horizontal frames and cols attribute defines vertical frames. Each frame is indicated by tag and it defines which HTML document shall open into the frame.

Note − The tag deprecated in HTML5. Do not use this element.

Example

Following is the example to create three horizontal frames −

         <body>Your browser does not support frames.</body>    

This will produce the following result −

Example

Let’s put the above example as follows, here we replaced rows attribute by cols and changed their width. This will create all the three frames vertically −

         <body>Your browser does not support frames.</body>    

This will produce the following result −

The Tag Attributes

Following are important attributes of the tag −

Specifies how many columns are contained in the frameset and the size of each column. You can specify the width of each column in one of the four ways −

Absolute values in pixels. For example, to create three vertical frames, use cols = «100, 500, 100».

A percentage of the browser window. For example, to create three vertical frames, use cols = «10%, 80%, 10%».

Using a wildcard symbol. For example, to create three vertical frames, use cols = «10%, *, 10%». In this case wildcard takes remainder of the window.

As relative widths of the browser window. For example, to create three vertical frames, use cols = «3*, 2*, 1*». This is an alternative to percentages. You can use relative widths of the browser window. Here the window is divided into sixths: the first column takes up half of the window, the second takes one third, and the third takes one sixth.

This attribute works just like the cols attribute and takes the same values, but it is used to specify the rows in the frameset. For example, to create two horizontal frames, use rows = «10%, 90%». You can specify the height of each row in the same way as explained above for columns.

This attribute specifies the width of the border of each frame in pixels. For example, border = «5». A value of zero means no border.

This attribute specifies whether a three-dimensional border should be displayed between frames. This attribute takes value either 1 (yes) or 0 (no). For example frameborder = «0» specifies no border.

This attribute specifies the amount of space between frames in a frameset. This can take any integer value. For example framespacing = «10» means there should be 10 pixels spacing between each frames.

The Tag Attributes

Following are the important attributes of tag −

This attribute is used to give the file name that should be loaded in the frame. Its value can be any URL. For example, src = «/html/top_frame.htm» will load an HTML file available in html directory.

This attribute allows you to give a name to a frame. It is used to indicate which frame a document should be loaded into. This is especially important when you want to create links in one frame that load pages into an another frame, in which case the second frame needs a name to identify itself as the target of the link.

This attribute specifies whether or not the borders of that frame are shown; it overrides the value given in the frameborder attribute on the tag if one is given, and this can take values either 1 (yes) or 0 (no).

This attribute allows you to specify the width of the space between the left and right of the frame’s borders and the frame’s content. The value is given in pixels. For example marginwidth = «10».

This attribute allows you to specify the height of the space between the top and bottom of the frame’s borders and its contents. The value is given in pixels. For example marginheight = «10».

By default, you can resize any frame by clicking and dragging on the borders of a frame. The noresize attribute prevents a user from being able to resize the frame. For example noresize = «noresize».

This attribute controls the appearance of the scrollbars that appear on the frame. This takes values either «yes», «no» or «auto». For example scrolling = «no» means it should not have scroll bars.

This attribute allows you to provide a link to another page containing a long description of the contents of the frame. For example longdesc = «framedescription.htm»

Browser Support for Frames

If a user is using any old browser or any browser, which does not support frames then element should be displayed to the user.

So you must place a element inside the element because the element is supposed to replace the element, but if a browser does not understand element then it should understand what is inside the element which is contained in a element.

You can put some nice message for your user having old browsers. For example, Sorry!! your browser does not support frames. as shown in the above example.

Frame’s name and target attributes

One of the most popular uses of frames is to place navigation bars in one frame and then load main pages into a separate frame.

Let’s see following example where a test.htm file has following code −

        <body>Your browser does not support frames.</body>    

Here, we have created two columns to fill with two frames. The first frame is 200 pixels wide and will contain the navigation menu bar implemented by menu.htm file. The second column fills in remaining space and will contain the main part of the page and it is implemented by main.htm file. For all the three links available in menu bar, we have mentioned target frame as main_page, so whenever you click any of the links in menu bar, available link will open in main page.

Following is the content of menu.htm file

   Google 
 
Microsoft 
 
BBC News   

Following is the content of main.htm file −

   
This is main page and content from any link will be displayed here.
 
So now click any link and see the result.
   

When we load test.htm file, it produces following result −

Now you can try to click links available in the left panel and see the result. The targetattribute can also take one of the following values −

Loads the page into the current frame.

Loads a page into a new browser window. Opening a new window.

Loads the page into the parent window, which in the case of a single frameset is the main browser window.

Loads the page into the browser window, replacing any current frames.

Loads the page into a named targetframe.
