The U.S. State Department launched a new Farsi-language Twitter feed Sunday in a bid to connect with internet users in Iran.
"US State Dept recognizes historic role of social media among Iranians. We want to join in your conversations," the department said in its first tweet.
The feed was launched just one day before opposition leaders and activists in Iran have called for a protest in support of the Egyptian revolution, according to Saham News. The rally is planned to coincide with the 25th day of Bahman, the 11th month of the Persian calendar.
Virtually every web designer I speak with is familiar with the ‘alt’ attribute: the part of the html ‘img’ tag that you use to provide an equivalent alternative for people who are unable to see the image. This includes people who are using a screen reader or people who are browsing the web with images turned off. What’s less commonly known is that there are five different classes of image used on web pages and each of those images requires a different approach to writing the ‘alt’ attribute.
The five different classes are:
* Eye candy.
* Clip art and stock images.
* Images that express a concept.
* Functional images.
* Graphs, complex diagrams and screenshots.
The ‘alt’ text you write will be different for each of these classes of image.
