幻灯片放映的样式问题

Question

嘿，伙计们，所以我在我构建的 jquery 滑块上设计了一个内容主体.....我的问题是我需要一些图片来拥有float: left，以便它们彼此对齐，但父级有一个 @ 987654323@ 如果我添加 float:left 它会从父 div 中消失......HTML：

 <div id="Content">
        <div class="main_Body">
            <div class="top-halfCont">
                <div class="online_training">
                    <div class="training_image">
                        <img src="images/onlinetraining_home_03.png" width="75" height="75" />
                    </div><!-- .training_image -->
                </div><!-- .online_training -->
                <div class="background_check">
                    <div class="background_image">
                        <img src="images/background_check_home_03.png" width="75" height="75" />
                    </div><!-- .background_image -->
                </div><!-- .background_check -->
                <div class="uninsured_alert">
                    <div class="uninsured_alert_image">
                        <img src="images/unisuredalert_system_03.png" width="75" height="75" />
                    </div><!-- .uninsured_alert_image -->
                </div><!-- .uninsured_alert -->
            </div><!-- .top-halfCont -->
        </div><!-- .main_Body -->
    </div><!-- #Content -->

风格：

/* main content #Content */
#Content {
    display:block;
    max-width:1200px;
    margin:0 auto;  
    background: white;
    position: relative;
    box-shadow: 5px 0px 13px #888888;
}
.main_Body {
    display:block;  
    margin: -6em 0 0 0;
    padding: 1em;
}
.online_training {
    display:block;
    width:200px;    
}
.training_image {
    width:75px;
    height:75px;
    margin:0 auto;  
}
.background_check {
    display:block;
    width:200px;
}
.background_image {
    width:75px;
    height:75px;
    margin:0 auto;  
}
.uninsured_alert {
    display:block;
    width:200px;
}
.uninsured_alert_image {
    width:75px;
    height:75px;
    margin:0 auto;  
}
