Insight is conducting a four-day class on ‘Introduction to HTML’ to the master trainers here. HTML is the most popular markup language for creating a website. A website is a virtual space for presenting a matter in a way that it turns on the visual modality of a person. But the imagery spins that most websites resort to are immaterial for a visually challenged person. The HTML lessons at Insight is a prerequisite and an attempt at discovering how a visually challenged person perceives a visual dominated realm. The class that began on 16 August will conclude on 19 August. Insight will assess the post-session performance of the participants to identify the potentiality of an advanced course in HTML.
