Systems and methods are disclosed herein for caching structural elements of electronic documents. A plurality of indices is stored in a data store. The plurality of indices corresponds to locations within an electronic document of portions of a stylized sub-element. A mutation to the electronic document is received and it is determined that the mutation pertains to a style of the stylized sub-element. Based on the mutation and the plurality of indices, the stylized sub-element is updated, and the portions of the updated stylized sub-element are caused to be displayed at a user device using a different style.

Systems and methods for caching structural elements of electronic documents

A method for updating a theme element of a presentation includes causing display of a user interface on a client computer of a user, the user interface comprising a first slide of the presentation and a first option to edit an element of the first slide, and receiving a user selection of the first option to edit the element of the first slide, wherein the user selection of the first option comprises a request to modify the element of the first slide. The method further includes causing the element of the first slide to be modified based on the user selection of the first option, receiving a user selection of a second option in the user interface to apply the modification to the element of the first slide to a theme of the presentation, causing the theme element corresponding to the element of the first slide to be updated based on the modification of the element of the first slide, and causing the modification of the element of the first slide to be propagated to elements of other slides of the presentation that are associated with the theme.

System and method for updating a master slide of a presentation

In a presentation document, changes to an element in a first slide of the presentation may be propagated throughout the presentation. A first slide may be displayed, in a user interface, with a first option to edit an element of the first slide. A selection of the first option may cause an edit to the first element. A second option may be displayed if the first element has a dependent relationship with a master element of the presentation. Upon selection of the second option, the master element may be updated based on the edit to the element of the first slide. The edit may be propagated to other elements of the presentation that have the dependent relationship with the master element.

Systems and methods are disclosed herein for caching structural elements of electronic documents. A plurality of indices is stored in a database. The plurality of indices corresponds to locations within an electronic document of portions of a structural element. A mutation to the electronic document is received. Based on the plurality of indices, it is determined that the mutation modifies the structural element. Based on the determination, the structural element is updated. The updated structural element is displayed at a user device.

A method to display changes to a master slide for a presentation includes receiving from a user on a client computer, a selection pertaining to the master slide in a presentation document comprising a plurality of slides, and identifying at least one slide in the presentation document that is dependent on the master slide. The method further includes providing, for display at the client computer, a presentation editing user interface comprising the master slide and the plurality of slides in the presentation document, the plurality of slides comprising the at least one dependent slide and one or more other slides that are not dependent on the master slide, wherein each dependent slide is automatically updated as edits are made to the master slide, and wherein the at least one dependent slide is to include a visual indicator that distinguishes the dependent slide from the other slides that are not dependent on the master slide.

System and method for highlighting dependent slides while editing master slides of a presentation

In a collaborative presentation document, changes may be propagated throughout related elements in dependent slides. When making a change to an individual slide in the presentation, if any master-dependent elements are found to exist in the presentation, an option is provided to allow the change to be added as a master element in the presentation. The added master element can be applied to the master slide and any resulting dependent slides.

A presentation document editing system provides master slides that can be associated with one or more other dependent slides in the presentation. When a slide in the presentation is edited, a preview of other slides in the presentation is displayed. When a master slide is edited, any dependent slides are shown in the preview with a visual indicator to distinguish the dependent slides from other slides in the presentation.

A method for rendering a document on a web browser includes receiving a portion of text within the document to be rendered on a web browser and determining a maximum height of the portion of text. A spacer element is inserted into the portion of text, where the spacer element has a height greater than the maximum height of the portion of text. A vertical position of the portion of text and the spacer element is adjusted by an offset, where a baseline of the portion of text is determined from the height of the spacer element and the offset. The portion of text is rendered on the web browser based at least in part on the baseline.

Mechanism for setting ascent and baseline for HTML elements

A system for collaborative presentation documents is provided that is capable of managing slides and elements of the document and modifications to the same using an index based list. Modifications to the document are distributed to multiple users in real time so that the presentation document is updated across all clients to reflect changes by any collaborative user.
