Artık resim hazır olduğunda, yapmamız gereken ikinci şey, küçük resmi oluşturduğumuz videoya bağlantı içeren basit bir HTML dosyası oluşturmak:

Next, we need to import jQuery in the head of the page: Then we use jQuery to set the display type (block) the width (500px to match the width of one 'frame' of our image) the height (203px) and the background of our link: ); Finally, we need to set the background so that the correct portion of our image is displayed; each 'frame' is 500px wide, so to show the first frame the x position of the background image should be 0px, to show the second it will be -500px, the third will be -1000px and so forth. Using a mousemove handler function, we can calculate the relative position of the cursor over the element as a percentage; we subtract the element's offset position from the event's pageX (this treats the left edge of the element as 0), then divide by the width of the element. Having done so we calculate the position of the background image by multiplying the percentage position by the total size of the composite image. We need the final result to be multiples of the element width (500px) so we divide the result by that value, round down using Math.floor(), then multiply back up to cancel out the division; if we don't do this the image will simply scroll 1px at a time. We subtract the resulting value from 0 so that all possible values are negative. Then we apply the background-position with CSS: The full script looks like this: );}); Western Norway at sunrise

Sonuç
Göz önünde bulundurulması gereken birkaç şey vardır: ilk olarak, yüzlerce 'kareye' sahip bir küçük resim oluşturmak mümkün olabilir, ancak bu çok düzgün bir animasyona yol açarken, aynı zamanda yüklenmesi uzun zaman alacak; ikincisi, fare pozisyonu tespiti sadece bir dokunmatik cihaz üzerinde çalışmayacak, bu yüzden bu teknik, bir şey elde etmediğiniz bir mobil cihazda kullanılabilirliğe zarar vermeyecektir.
Küçük resmin amacı, kullanıcıya bir bağlantının diğer ucunda ne olduğu hakkında daha fazla bilgi sunmaktır. Bağladığınız kaynak bir video olduğunda, tek bir görüntü genellikle yeterli bilgi değildir. CSS sprite tekniğini genişletmek, tek bir kareden daha fazlasını önizlemenin basit ve etkili bir yoludur.
Küçük resimlerde videoyu nasıl önizlersiniz? Tek bir görüntüden daha fazlasını kullanıyor musunuz? Yorumlarda bize bildirin.
