I’ve worked with Flash for several years and have always been slightly dissatisfied with the markup needed to embed a movie in web pages. When I recently published a site in XHTML, my dissatisfaction with the markup grew as I realized that it simply wasn’t valid in this context and was bloating my pages to unacceptable levels. A leaner, standards-compliant method of embedding Flash movies was called for.

The Twice-Cooked Method

Flash has always shipped with some method of generating an HTML page to contain Flash movies. Initially, it was a tool called AfterShock. Since the release of Flash 4, authors can export HTML pages with embedded movies from within the Flash authoring environment. This markup produced by Flash is the de facto standard that you’ll find in 99% of sites that use Flash movies.

Sebagai teks alternatif, atribut (bukan tag) alt ditujukan untuk memberi informasi tambahan yang serupa pada konten non-teks. Jadi, jika suatu konten non-teks tidak ditampilkan/terbaca, pengguna/pengunjung tidak akan kehilangan informasinya. Teks alternatif (teks alt) dapat berupa teks pendek atau bahkan deskripsi yang agak panjang.
