The difference between273238ce9338fbb04bee6997e5552b95 and d8e2720730be5ddc9c2a3782839e8eb6 tags: Both are objects used to play multimedia files, the object element is used for IE browser, and the embed element is used for non- IE browser, in order to ensure compatibility, usually we use two elements at the same time, and the browser will automatically ignore tags it does not support. When using two elements at the same time, the d8e2720730be5ddc9c2a3782839e8eb6 tag should be placed inside the 273238ce9338fbb04bee6997e5552b95 tag.
