PROBLEM TO BE SOLVED: To perform designation of a part in a page uniquely even when same elements coexist in the page, and prevent such a situation in which positional deviation of display of a tag to the designated part occurs, even when a display environment is varied.SOLUTION: Part designation is performed by using index information which indicates an order of designation elements corresponding to part designation portions, in plural elements, instead of part designation using a relative coordinate. Namely the relative coordinate related to the part designation portions is converted into index information which indicates the order of designation element corresponding to the part designation portions in the plural elements, and the index information obtained by the conversion is used for designating a part in the page. Therefore, even same elements coexist in the same page, designation of a part in the page is performed uniquely, and a situation in which positional deviation of display of a tag to the designated part occurs, can be prevented, even when a display environment is varied. |
