css - div 高度显示不正确

Question

我有一个 div 元素，里面有两个 div 元素，内部 div 是 float 的。但我想要具有自动高度的主 div。不固定。并且背景必须正确显示。当我将高度设置为 250px 时，背景仅显示 250px 区域。但是当我将高度设置为 auto 时，背景没有显示。如何使背景显示为自动高度？

我的 HTML 代码:-

<div class="ejz_wc" id="ejz_wc">
    <div class="ejz_wc_main" id="ejz_wc_main">
        <div class="ejz_wcm_txt">
            <h2 class="ejz_wc_1_h2">Welcome</h2>
            <p class="ejz_wc_msg">
            If you are new to us then Register a free account today .<br />
            We are here to give you entertainment
            </p>
            <div class="wclinks">
            <a href="<? echo $url; ?>/info/about.php">Learn moare about us</a><br />
            <a href="<? echo $url; ?>/info/payment.php">Learn more about Payment</a><br /><br />
            <a href="ez-register.php#free">Register</a> for a free Account<br />
            <a href="ez-register.php#performer">Register</a> for a Premium Account<br />
            </div>
        </div>
        <div class="ejz_wc_box">
            <div class="ejz_wcbox">
                <h3>Sign In</h3>
                <p>Sign in to us

                <center><a class="lnksnrg" href="ez-login.php"><div class="signin_ejz">Login</div></a></center>
                <h3>Not registered yet?</h3>
                Register now and get access to all items.</p>
                <br />
                <center><a class="lnksnrg" href="ez-login.php"><div class="register_ejz">Register</div></a></center>
            </div>
        </div>
    </div>
</div>

Answer 1

在“.ejz_wc_main”中提及overflow:hidden 将解决您的问题。

.ejz_wc_main {
    background: none repeat scroll 0 0 green;
    border-radius: 10px 10px 10px 10px;
    font-family: 'Segoe UI','Tahoma Bold','Arial Bold','Helvetica Bold',sans-serif;
    height: 100%;
    overflow: hidden;
    width: 100%;
}
