What does html5 consist of?
HTML5 consists of document structure, layout (Flexbox, Grid), multimedia, canvas, forms, API and other features, including semantic markup, web storage and web sockets, providing richer, more flexible and interactive style web development experience.
##Composition of HTML5
HTML5 is a breakthrough technology in the field of web development, which introduces many new functions and features. HTML5 consists of the following main parts:1. Document structure
HTML5 uses semantic markup to define the structure of the document, including<nav>, <section>, <aside>, and <footer>. These elements help browsers and search engines understand how content is organized.
Flexbox and Grid are two powerful tools in HTML5 for creating flexible and responsive layouts. Flexbox allows for flexible arrangement of elements along a horizontal or vertical axis, while Grid provides finer layout control and can create complex layouts.
3. MultimediaHTML5 introduces support for audio (

Do I need to use flexbox in the center of the Bootstrap picture?
Apr 07, 2025 am 09:06 AM
There are many ways to center Bootstrap pictures, and you don’t have to use Flexbox. If you only need to center horizontally, the text-center class is enough; if you need to center vertically or multiple elements, Flexbox or Grid is more suitable. Flexbox is less compatible and may increase complexity, while Grid is more powerful and has a higher learning cost. When choosing a method, you should weigh the pros and cons and choose the most suitable method according to your needs and preferences.
How to calculate c-subscript 3 subscript 5 c-subscript 3 subscript 5 algorithm tutorial
Apr 03, 2025 pm 10:33 PM
The calculation of C35 is essentially combinatorial mathematics, representing the number of combinations selected from 3 of 5 elements. The calculation formula is C53 = 5! / (3! * 2!), which can be directly calculated by loops to improve efficiency and avoid overflow. In addition, understanding the nature of combinations and mastering efficient calculation methods is crucial to solving many problems in the fields of probability statistics, cryptography, algorithm design, etc.

std::unique removes adjacent duplicate elements in the container and moves them to the end, returning an iterator pointing to the first duplicate element. std::distance calculates the distance between two iterators, that is, the number of elements they point to. These two functions are useful for optimizing code and improving efficiency, but there are also some pitfalls to be paid attention to, such as: std::unique only deals with adjacent duplicate elements. std::distance is less efficient when dealing with non-random access iterators. By mastering these features and best practices, you can fully utilize the power of these two functions.

How to implement data storage on H5 page production
Apr 05, 2025 pm 11:57 PM
H5 page data storage provides a variety of options to allow pages to store data and avoid amnesia after refresh. Common methods include: localStorage: permanently store string data, suitable for storing important and persistent data. sessionStorage: Temporarily store string data during the session, suitable for storing shopping cart products and other data that do not need to be saved for a long time. IndexedDB: Database-level storage, which can store a large amount of structured data, but the API is complex. The data format is unified into a string, and complex data needs to be converted in JSON. At the same time, pay attention to data security, error handling and multi-page synchronization.
