以下页面代码有一个问题，当我最小化网页时，布局变得困惑并且页面元素“DIV”受到干扰，请尝试并继续最小化浏览器以查看会发生什么，然后告诉我如何解决这个问题。

.banner{
        border:2px solid;
        background-color:#c9c9c9;
        position:absolute;

        top:0.5%;       
        height:21%;
        width:96%;
        align:center;
    }

.ban_pad{
        padding:10px;
    }


.search_block_position{
        position:absolute;
        left:2.5%;
        top:55%;
    }


.search_box{
        border-color:#4B8A08;
        border-style:solid;



    }


.search_button{
        border-color:#4B8A08;
        border-style:solid;
        background-color:#4B8A08;
    }


.logo{
        border:solid 2px #000;
        background-color:#00f;
        width:30%;
        height:60%;
        position:inherit;
        top:2%;
        right:.5%;
    }


.banner_items{
        border:solid 1px #000;
        position:absolute;
        top:51%;
        left:41%;
        color:#fff;
    }



</style>

<div class="ban_pad">
<div class="banner">

<img src="../images/logo.jpg" class="logo" alt="logo here">

<div class="banner_items" style="left:32%">
<img src="../images/add_book.jpg"><p style="position:relative;top:-18px;">Add</p>
</div>

<div class="banner_items">
<img src="../images/request_book.png"><p style="position:relative;top:-18px;">Request</p>
</div>

<div class="banner_items" style="left:50%">
<img src="../images/join_stuff.gif"><p style="position:relative;top:-18px;">join</p>
</div>

<div class="search_block_position">
<input type="submit" name="search_button" class="search_button" value="search" style="color:#fff">&nbsp;<input      type="text" name="search" class="search_box">
</div>

最佳答案

试试这个。它可能仍然需要一些修复，但它应该在主要浏览器中呈现得很好。该代码包括在线解释。
