今天則是在原有的基礎上，在 Project 詳細資訊中新增標籤與分類。

主要修改的部分為：

<div id="projectModal" class="modal">
    <div class="modal-content">
        <span class="close" onclick="closeProjectDetails()">&times;</span>
        <h2 id="modalTitle"></h2>
        <p id="modalDescription"></p>
        <div id="modalTags"></div>
        <div id="modalCategories"></div>
    </div>
</div>

新增 div#modalTags 與 div#modalCategories 作為放置標籤與分類的容器。

const modal = document.getElementById("projectModal");
const modalTitle = document.getElementById("modalTitle");
const modalDescription = document.getElementById("modalDescription");
const modalTags = document.getElementById("modalTags");
const modalCategories = document.getElementById("modalCategories");

function showProjectDetails(projectId) {
    const projectDetails = getProjectDetails(projectId);

    modalTitle.textContent = projectDetails.title;
    modalDescription.textContent = projectDetails.description;
    modalTags.textContent = projectDetails.tags;
    modalCategories.textContent = projectDetails.categories;

    modal.style.display = "block";
}

function getProjectDetails(projectId) {
    const projects = {
        1: {
            title: "Project 1",
            description: "詳細描述 Project 1...",
            tags: ["HTML", "CSS", "JavaScript"],
            categories: ["Web Development"]
        },
        2: {
            title: "Project 2",
            description: "詳細描述 Project 2...",
            tags: ["Vue", "React", "Angular"],
            categories: ["Frontend"]
        },
        3: {
            title: "Project 3",
            description: "詳細描述 Project 3...",
            tags: ["Node.js", "Golang", "Python"],
            categories: ["Backend"]
        }
    };
    return projects[projectId];
}
