In an exemplary method, metadata of a web page can be obtained. The metadata can specify a first-screen key element and include a first-screen-strategy extended attribute. A value of the first-screen-strategy extended attribute can indicate whether a page-defined first-screen display strategy is mandatory or optional. An element of the web page can be parsed in such a way as to determine whether the element is the first-screen key element. When the element is the first-screen key element, a first screen of the web page can be displayed. When the element is not the first-screen key element and a first-screen display criterion is met, a first screen of the web page can be displayed. The first-screen display criterion can be a function of the value of the first-screen-strategy extended attribute. ## Claims ### Claim 1 A method for displaying a web page, comprising: obtaining metadata of a web page, the metadata specifying a first-screen key element and including a first-screen-strategy extended attribute, a value of the first-screen-strategy extended attribute indicating whether a page-defined first-screen display strategy is mandatory or optional;

or when the value of the first-screen-priority extended attribute indicates the priority for displaying the first-screen of the web page is normal, sending a layout-region-change request and parsing a next element of the web page. ### Claim 6 (depends on 4) The method according to claim 4, wherein, when the value of the first-screen-priority extended attribute indicates the priority for displaying the first-screen of the web page is high, the displaying of the first screen of the web page includes: painting all of elements of the first screen in one painting process, none of the elements of the first screen being painted prior to the one painting process. ### Claim 7 (depends on 5) The method according to claim 5, wherein, when the value of the first-screen-priority extended attribute indicates the priority for displaying the first-screen of the web page is normal, and after sending a layout-region-change request, the method further includes: updating a layout region of the first screen of the web page; and sending a screen-paint request for painting the updated layout region. ### Claim 8 An electronic device for displaying a web page, comprising a processor, a display system, and a memory, the memory having thereon encoded instructions that causes the electronic device to display a web page on the display system by a process comprising: obtaining metadata of a web page, the metadata specifying a first-screen key element and including a first-screen-strategy extended attribute, a value of the first-screen-strategy extended attribute indicating whether a page-defined first-screen display strategy is mandatory or optional; parsing an element of the web page in such a way as to determine whether the element is the first-screen key element; when the element is the first-screen key element, displaying a first screen of the web page; and when the element is not the first-screen key element and a first-screen display criterion is met, displaying a first screen of the web page, the first-screen display criterion being a function of the value of the first-screen-strategy extended attribute. ### Claim 9 (depends on 8) The electronic device according to claim 8, wherein the first-screen display criterion includes: the value of the first-screen-strategy extended attribute indicating that the page-defined first-screen display strategy is optional. ### Claim 10 (depends on 9) The electronic device according to claim 9, wherein the first-screen display criterion further includes: a browser-defined first-screen display strategy being satisfied. ### Claim 11 (depends on 8) The electronic device according to claim 8, wherein the metadata further includes a first-screen-priority extended attribute, a value of the first-screen-priority extended attribute indicating whether a priority for displaying the first-screen of the web page is high or normal. ### Claim 12 (depends on 11) The electronic device according to claim 11, wherein, when the element is not the first-screen key element and the first-screen display criterion is not met, the process further includes: when the value of the first-screen-priority extended attribute indicates drat the priority for displaying the first-screen of the web page is high, proceeding to parse a next element of the web page without sending a layout-region-change request;
