描述

在创建网页时，Chrome DevTools 上的一切都按预期运行，直到我尝试了移动版本。为什么会发生这种情况？从来没有遇到过这样的问题。

重现步骤

这就是桌面版本的情况。

减小宽度后：

这是预料之中的。当我激活移动版时，它突然无法使用：

即使使用 flex + flex-wrap + flex-direction 或使用 grid + grid-template-columns: Repeat(auto-fit, minmax(250px, 1fr)); 的 .cards 类，它也不起作用移动设备。

环境

我使用的代码如下：

const data = [
  {
    CODIGO: "a1",
    NOME: "TESTING",
    CLASSE: "ALUNO",
  },
  {
    CODIGO: "a2",
    NOME: "TESTING",
    CLASSE: "ALUNO",
  },
  {
    CODIGO: "a3",
    NOME: "TESTING",
    CLASSE: "ALUNO",
  },
  {
    CODIGO: "a4",
    NOME: "TESTING",
    CLASSE: "ALUNO",
  },
  {
    CODIGO: "a5",
    NOME: "TESTING",
    CLASSE: "ALUNO",
  },
  {
    CODIGO: "a6",
    NOME: "TESTING",
    CLASSE: "ALUNO",
  },
];

const groupByKey = (list, key, { omitKey = false }) =>
  list.reduce((hash, { [key]: value, ...rest }) => {
    const item = omitKey ? rest : { [key]: value, ...rest };
    const group = hash[value] || [];
    return { ...hash, [value]: [...group, item] };
  }, {});

const result = groupByKey(data, "CLASSE", { omitKey: true });
const ALUNO = result.ALUNO;
const PROFESSOR = result.PROFESSOR;
const MIDIA = result.MIDIA;
const PASTOR = result.PASTOR;

document.addEventListener("DOMContentLoaded", function () {
  const listElements = {
    alunoList: document.getElementById("alunos"),
    professorList: document.getElementById("professores"),
    midiaList: document.getElementById("midia"),
    pastorList: document.getElementById("pastores"),
  };

  const createCard = (person, aluno = false) => {
    const card = document.createElement("div");
    card.classList.add("card");

    const cardImage = document.createElement("div");
    cardImage.classList.add("card__image");
    const image = new Image();
    image.src = `assets/img/${person.CODIGO}i.webp`;
    cardImage.appendChild(image);

    const cardContent = document.createElement("div");
    cardContent.classList.add("card__content");
    const cardTitle = document.createElement("div");
    cardTitle.classList.add("card__title");
    cardTitle.innerHTML = person.NOME;
    const cardText = document.createElement("p");
    cardText.classList.add("card__text");
    const cardLink = document.createElement("a");
    cardLink.setAttribute("target", "_blank");
    cardLink.setAttribute("href", `${person.CODIGO}.html`);
    const cardButton = document.createElement("button");
    cardButton.classList.add("btn");
    cardButton.classList.add("btn--block");
    cardButton.innerHTML = "Mais detalhes ➜";
    cardLink.appendChild(cardButton);
    cardContent.appendChild(cardTitle);
    cardContent.appendChild(cardText);
    cardContent.appendChild(cardLink);

    card.appendChild(cardImage);
    card.appendChild(cardContent);

    const li = document.createElement("li");
    li.classList.add("cards__item");
    li.appendChild(card);
    return li;
  };

  const addCardsToList = (personList, person, aluno = false) => {
    listElements[personList].appendChild(createCard(person, aluno));
  };

  ALUNO.forEach((person) =>
    addCardsToList("alunoList", person, (aluno = true))
  );
});

因为这从未发生在我身上，所以我什至不知道从哪里开始。我知道这是由于 CSS 造成的，但任何提示都会很棒。

谢谢！
