How to properly link the Bootstrap JS file?

Decentraland is a decentralized virtual reality platform based on Ethereum. Its LAND is ERC-721NFT. It is driven by MANA tokens for transactions and DAO governance. It supports users to create and deploy 3D scenes and bind ENS identities.

JSFiddle (https://jsfiddle.net/) is a one-stop online JavaScript programming platform that supports HTML/CSS/JS three-column real-time preview, multi-frame integration, Fork learning, account saving, minimalist startup, teaching embedding, device simulation and code sharing.

The movie ticketing system requires 5 core tables: cinemas (theaters), movies (movies), schedules (schedules), seats (seats), orders (orders), and the others are auxiliary; seats are dynamically generated according to schedules, and UNIQUEKEY is used to constrain them to prevent duplication. For small and medium-sized order systems, JSON can be used to store seat_ids, and high concurrency needs to be split into the order_seats table.

A reduce-only order is a risk control instruction that forces only the reduction or clearing of existing positions and prohibits the opening of new positions. It verifies positions in real time through order-level parameters, and supports manual opening on the four platforms of Binance, OKX, Bybit, and HTX. Limit orders can be used to lock the price and position boundaries. The API must explicitly pass "reduceOnly": true, and conditional orders must be enabled separately in templates such as take profit.

EVM compatibility means that the blockchain can execute the Ethereum Virtual Machine bytecode, so that Solidity contracts can be deployed and run without modification. Its essence is to unify execution standards, accelerate cold start through ecological reuse, reduce risks through security model inheritance, support multi-chain interoperability, and allow economic model optimization to improve the experience.

ERC-721 is the Ethereum NFT standard protocol. It achieves irreplaceability through unique tokenID and supports ownership query, secure transfer, fine-grained authorization, on-chain metadata and ERC-165 interface declaration to ensure cross-platform compatibility and verifiability.

Generative art NFTs are digital artworks that are programmable on the chain. Artists submit algorithm scripts instead of static images. Users use transaction hashes as seeds to dynamically generate unique visual content when minting. The image data is stored off-chain but the logic and metadata are solidified on the chain.

Transition does not take effect because class switching occurs in the same rendering frame, and the browser skips the intermediate state; adding the class to the next frame should be delayed, or forced to reflow; transitionend does not trigger pseudo elements and inherited attributes, and needs to monitor specific attributes and be compatible with Safari.
