Adding Image on the web page:

Images can improve the design and the appearance of a web page. For adding pictures into the web page, we can use the <img> tag. The <img> tag is an empty tag which mean it has no ending tag (i.e. no </img>) associated with it. The following formats of image are used on the webpage-

  • JPG (Joint Photographic Group),
  • JPEG (Joint Photographic Experts Group),
  • PNG (Portable Network Graphics),
  • GIF (Graphics Interchange Format),
  • SVG (Scalable Vector Graphics),
  • BMP (bitmap)

The syntax of using <img> tag is:

<img src = “path or URL” alt = “alternate_text”>

 

Attributes used in <img> tag:

The <img> tag has two required attributes: src and alt. The attributes: align, border, hspace, and vspace are not supported in HTML5.

 

The “src” attribute of IMG Tag:

–This attribute helps in specifying the image’s source, which means this, instruct your web browser from which location it must fetch the particular picture (in other words specify the path). src attribute takes path or URL as its value in quotes.

–The source’s image may exist locally on your computer (need a path to specify) or may reside somewhere in the web server (need URL to specify).

–For images in your local PC, if the image and the webpage are in the same folder on the local computer, you have to write only the image name and format. Otherwise you have to write the full path of the image.

Example-1: HTML code to add an image called logo.jpg which is stored on the desktop to a webpage that is located on the desktop-

Example-2: HTML code to add a picture called logo.jpg which is stored in the “picture” folder of F drive to a webpage that is located on the desktop-

 

The “alt” attribute of IMG Tag:

–This attribute of Image Tag or <img> tag allows you in defining an alternative text in case your browser becomes unsuccessful in loading the image.

–There may be situations when your browser might not be able to display that particular image either because of slow connection or server error or any other reason.

–Moreover, search engines take up those alternate texts given to images and help to find articles or content related to that text.

Example-3: HTML code to add an image called sagc_logo.jpg which is stored on the desktop to a webpage that is located on the desktop-

 

The “width” and “height” attribute: 

–In case you need a specific size of the image for fitting it into your web page, you can use the width and height attribute of the IMG tag.

You can use both px (pixels) and % (percent) as a relative unit for specifying size (here height and width) of the image.

If the size of the image is 200×150, then the first number (200) indicates the width and the second number (150) indicates the height.

Example-4: HTML code to add a picture called logo.jpg in 200×300 dimension which is stored in the “photo” folder of E drive to a webpage that is located on the desktop-

You can also use the style attribute to specify the width and height of an image.

The above HTML code can also be written using “style” attribute-

 

Hyperlink:

You might know that hyperlink which is a powerful means of browsing from web pages and websites. It is developed for sending the readers or those who will perform surfing from one web page to another without opening a new tab or window. This is in general term said to as link and is given a reference to jump to another page or document or from one part of the same page to another using a hypertext. The Anchor tag (<a>) in HTML can be defined as a means to create a hyperlink.

Anchor can link your current page on which the text is being converted to hypertext via <a> (anchor tag) to another page. This anchoring from one page to another is made possible by the attribute “href”, which can be abbreviated as (hypertext reference).

Syntax:

<a href= “url” > link text/image </a>

The href attribute specifies the destination address of the link. The link text or image is the visible part (Visit our HTML tutorial). Clicking on the link text or image will send you to the specified address.

 

Types of hyperlink: Three types of hyperlink. They are-

  • Global: Linking with different websites.
  • Local: Linking with different web pages of the same website.
  • Internal: Linking with different sections of the same web page.

 

Attributes used in anchor(<a>) tag:

 

Example-1: Link text is “EduPointBD” and URL is http://www.edupointbd.com . HTML code-

 

Anchor tags can be used to create hyperlink through images also. Here’s a code snippet to show how to perform that.

Example-2: Link image is “logo.png” and URL is http://www.edupointbd.com . HTML code-
