Some browsers will have options to turn off certain dynamic figures, such as images, videos, flash files, and such. When these certain figures do not appear, an alternate message is displayed instead. This message is set with the "alt" attribute, which is only valid in a few tags. Also, when some browsers see that cursor is hovering over an image, the alternate text is displayed. It should be noted that the alt attribute is required for those who wish to comply with some w3 Document Type Declarations. ---- <img src="duck.jpg" alt="A duck" /> ----
There is an attribute which defines the name of the image to be displayed. The attribute is called as ALT or alternate.
ALT
Alt text (alternative text) is a word or phrase that can be inserted as an attribute in an HTML (Hypertext Markup Language) document to tell Web site viewers the nature or contents of an image. The alt text appears in a blank box that would normally contain the image.
You use the alt attribute on the image tag. The alt attribute takes a short description of the image for its value. For instance:If the browser failed to load the image (for instance, if it wasn't present on the server where I said it was) or if it had images turned off, or if were a screen-reader used by the visually impaired, then the alt text is display/read.The W3C makes an alt attribute a requirement on all valid IMG tags since HTML 4.01.
the tag is used to insert images. It is an empty element that only has attributes. Two attributes are required for the element: the src attribute and the alt attribute. The src attribute specifies the path of the image file. The alt attribute specifies an alternative text for the image, if the image is unavailable. The syntax for the tag is as follows: To know more check out the cronj IT site.
simply use the <img> tag... include the src attribute and link it to the images URL like so: <img src="http://www.whateverTheUrlIs.com"> you should also include the <alt> attribute to make your code perfect: <img src="........" alt=".....">
The alt attribute in HTML is used to attach a short description to an image. This description can be used by screen readers which are aiding the visually impaired. Browsers will also show the alt text while the page loads. If you have images in the browser turned off, the alt text will be displays in place of the image. Let's say we have an image that represents a stop sign. We use this image to stop the processing going on in our web application. <img src="stopsign.png"> The W3C requires an alt attribute. In this case, a good alt attribute won't simply describe the image, but rather describe what the image does. <img src="stopsign.png" alt="Stop Processing"> An alt tag is required on every image to maintain compliance with the W3C specifications.
It is acceptable to use an empty alt attribute on images when you are telling screen readers and other assistive technology that the image can be safely ignored.
Use the 'alt' attribute. Eg ""
A tag is a declaration of a HTML object whereas an Attribute is a property of an object.
The color of a hyperlink that has not been clicked can be specified by setting the "BGCOLOR" attribute in the HTML tag.
