在javascript中更改警察/字體大小

Question

您好，所以我想更改答案的大小，但它是在 javascript 中，我不知道如何更改它，因為我無法在我的 css 文件中更改它。

let questions = [
    {
        question: 'Quel est la capitale de la France?',

        answers:[
            { text : 'tokyo', correct:'false', index:1 },
            { text : 'juin', correct:'false', index:2 },
            { text : 'ab', correct:'false', index:3 },
            { text : 'paris', correct:'true', index:4 }
        ]
    },

    {
        question: 'Quel est la capitale de la belgique?',

        answers:[
            { text : 'tokyo', correct:'false', index:1 },
            { text : 'juin', correct:'false', index:2 },
            { text : 'ab', correct:'false', index:3 },
            { text : 'paris', correct:'true', index:4 }
        ]
    }

您可以像這樣更改文本字段的樣式：

 let q1,a1; let questions = [ { question: 'Quelle est la capitale de la France?', answers:[ { text: 'tokyo', correct:'false', index:1 }, { text: 'juin', correct:'false', index:2 }, { text: 'ab', correct:'false', index:3 }, { text: 'paris', correct:'true', index:4 } ] }, { question: 'Quelle est la capitale de la Belgique?', answers:[ { text: 'tokyo', correct:'false', index:1 }, { text: 'juin', correct:'false', index:2 }, { text: 'ab', correct:'false', index:3 }, { text: 'bruxelles', correct:'true', index:4 } ] } ] window.addEventListener("DOMContentLoaded",changeFontStyle); function changeFontStyle(){ q1 = document.getElementById("question1"); a1 = document.getElementById("answer1"); q2 = document.getElementById("question2"); a2 = document.getElementById("answer2"); let fontFam='Helvetica,"sans-serif"'; q1.style.color="#ff0000"; q1.style.fontSize="20pt"; q1.style.fontFamily = fontFam; q1.style.fontWeight="bold"; a1.style.color="#008800"; a1.style.fontSize="16pt"; a1.style.fontFamily = fontFam; a1.style.fontWeight="normal"; q2.style.color="#ff0000"; q2.style.fontSize="20pt"; q2.style.fontFamily = fontFam; q2.style.fontWeight="bold"; a2.style.color="#008800"; a2.style.fontSize="16pt"; a2.style.fontFamily = fontFam; a2.style.fontWeight="normal"; q1.innerHTML = questions[0].question; a1.innerHTML = questions[0].answers[3].text; q2.innerHTML = questions[1].question; a2.innerHTML = questions[1].answers[3].text; }
