我确实有这段 html 和 css 代码，我希望我的表（id =“表”）在“框”中的位置更高。但是在标有“Kalkulatory macierzowe”的标题上方有一点边距。所以我该如何解决？HTML

<div id = "box">    
<div class = "table" id = "table">
<div id = "header">Kalkulatory macierzowe</div>

<div id = "table1">
<div class = "header">Wyznacznik [2x2]</div>
    <form id = "row1">
        <input type = "text" class = "det1"/><!--first row-->
        <input type = "text" class = "det1"/>
    </form>
    <form id = "row2">
        <input type = "text" class = "det1"/><!--second row-->
        <input type = "text" class = "det1"/>
    </form>
    <div class = "count"><a href = "#"  onclick="det('det1','caclValue2')">Wylicz</a></div>
        <input type = "text" id = "calcValue2"/>
    </div>

<div id = "table2">
<div class = "header">Wyznacznik [3x3]</div>
 <form id = "row1"><!--first row-->
    <input type = "text" class = "det"/>
    <input type = "text" class = "det"/>
    <input type = "text" class = "det"/>
 </form>
 <form id = "row2"><!--second row-->
    <input type = "text" class = "det"/>
    <input type = "text" class = "det"/>
    <input type = "text" class = "det"/>
</form>
<form id = "row3"><!--third row-->
    <input type = "text" class = "det"/>
    <input type = "text" class = "det"/>
    <input type = "text" class = "det"/>
</form>
<div class = "count" onclick="det(3,'det')"><a href = "#">Wylicz</a></div>
<input type = "text" id = "calcValue1"/>
</div>

<div id = "table3">
<div class = "header">Macierz odwrotna [2x2]</div>
 <form id = "row1">
    <input type = "text" class = "det2"/><!--first row-->
    <input type = "text" class = "det2"/>
 </form>
 <form id = "row2">
    <input type = "text" class = "det2"/><!--second row-->
    <input type = "text" class = "det2"/>
</form>
<div class = "count" onclick="invertedMatrix(2,'det2')"><a href = "#">Wylicz</a>    </div>
</div>
</div>
</div>

听起来你需要这个：

body {margin: 0;}
