我正在练习 HTML 和 CSS。我有一个与以下代码相关的问题-
.outer_class{
position: absolute;
width: 50%;
height: 30%;
top: 35%;
left: 25%;
background-color: red;
}
.inner_class{
position: relative;
width: 50%;
height: 50%;
top: 25%;
left: 25%;
background-color: yellow;
}
.div_input{
position: relative;
width: 70%;
height: 50%;
top: 25%;
left: 15%;
background-color: blue;
}
input[type="text"]{
box-sizing: border-box;
width: 100%;
height: 100%;
}<!DOCTYPE html>

<div class="outer_class">
<div class="inner_class">
<div class="div_input">
<input type="text" name="username">
</div>
</div>
</div>
</body>
</html>现在，当我将浏览器窗口调整到最小时，会显示一点蓝色 div。为什么会这样，我该如何解决？
提前致谢!
