css问题，求知道的人帮助一下

图片说明
想达到是效果是上图

但是不知道怎么搜索栏跑到了下面。公告和搜索栏我是放在同个div下面的。但是不知道怎么不在一行里，css菜鸟求帮助啊。

        <div id="Scroll"> 
        <div id="ScrollMe" style="overflow: hidden; height: 27px; "> 
        <% 
                List<WebContent> listWebContent1 = WebContentAction.query("12",1,4);
                for (WebContent obj : listWebContent1) {
        %>
                <a href="<%=request.getContextPath()%>/website/webContent.jsp?category=12&parentID=12&id=<%=obj.getId()%>" title="<%=obj==null?"":obj.getName() %>"><%=StringUtil.substr(obj.getName(), 10)%></a>
                            <%
                                }
                            %>
        <br/> 
        <% 
                List<WebContent> listWebContent2 = WebContentAction.query("12",2,4);
                    for (WebContent obj : listWebContent2) {
        %>
                    <a href="<%=request.getContextPath()%>/website/webContent.jsp?category=12&parentID=12&id=<%=obj.getId()%>" title="<%=obj==null?"":obj.getName() %>"><%=StringUtil.substr(obj.getName(), 10)%></a>
                                            <%
                                                }
                                            %>
        <br/> 
        </div> 
        </div>

    <script>new srcMarquee("ScrollMe",0,1,900,27,3,3000,1000,27)</script> 
    </div>
    <div class="searchBox">
    <form method="post" id="searchform"  height= "27"action="<%=request.getContextPath() %>/website/search.jsp">
        <fieldset>
        <input id="search" name="search" type="text" value="" class="text_input" action="<%=request.getContextPath() %>/website/search.jsp" />
        <input id="search_a" name="submit" type="submit" value="" /> </fieldset>
    </form>
    </div>

    </div>
    </div>

无代码，无法解决。不过你看一下是否是高度，浮动，定位等的问题。

div里放2个div设置float，设置长度

        <div id="Scroll"> 
        <div id="ScrollMe" style="overflow: hidden; height: 27px; "> 
        <% 
                List<WebContent> listWebContent1 = WebContentAction.query("12",1,4);
                for (WebContent obj : listWebContent1) {
        %>
                <a href="<%=request.getContextPath()%>/website/webContent.jsp?category=12&parentID=12&id=<%=obj.getId()%>" title="<%=obj==null?"":obj.getName() %>"><%=StringUtil.substr(obj.getName(), 10)%></a>
                            <%
                                }
                            %>
        <br/> 
        <% 
                List<WebContent> listWebContent2 = WebContentAction.query("12",2,4);
                    for (WebContent obj : listWebContent2) {
        %>
                    <a href="<%=request.getContextPath()%>/website/webContent.jsp?category=12&parentID=12&id=<%=obj.getId()%>" title="<%=obj==null?"":obj.getName() %>"><%=StringUtil.substr(obj.getName(), 10)%></a>
                                            <%
                                                }
                                            %>
        <br/> 
        </div> 
        </div>

    <script>new srcMarquee("ScrollMe",0,1,900,27,3,3000,1000,27)</script> 
    </div>
    <div class="searchBox">
    <form method="post" id="searchform"  height= "27"action="<%=request.getContextPath() %>/website/search.jsp">
        <fieldset>
        <input id="search" name="search" type="text" value="" class="text_input" action="<%=request.getContextPath() %>/website/search.jsp" />
        <input id="search_a" name="submit" type="submit" value="" /> </fieldset>
    </form>
    </div>

    </div>
    </div>

    代码附上了

给你提供三个属性一般在审查元素调试下就出来了看看到底是哪出问题 position:absolute/relative display:block/... float:...

公告的那个DOM设置成float:left,搜索的设置成float:right
