Question

当你找到＆＃34; hard＆＃34;简单的东西和简单的东西很难！

我不确定为什么我会在看起来非常简单的html和/或css问题上寻求帮助，但我在这里。

请查看截图，了解问题的视觉效果。即使我已经通过div和html语法检查，我的电子设备似乎到处都是，这也适用于我的页脚。我认为css是正确的，但也许我在某个地方错过了一个div。我需要一双新鲜的眼睛才能看到我明显不喜欢的东西。

所以我添加了我的getItem函数（）

＆＃13;

function getItem(){
   global $con;
    
    //limit to just getting 6 random products per page
    $get_item = "select * from items order by RAND() LIMIT 0,6";
    $run_item = mysqli_query($con,$get_item);
    
    //using while loop to get multiple data from items table
    
    while($row_item = mysqli_fetch_array($run_item)){
        
        $item_id = $row_item['item_id'];
        $item_cat = $row_item['item_cat'];
        $item_brand = $row_item['item_brand'];
        $item_title = $row_item['item_title'];
        $item_price = $row_item['item_price'];
        $item_image = $row_item['item_image'];
        
        
        
        echo "
				<div id='single_item'>
				
					<h3>$item_title</h3>
                    <img src='admin_area/item_imgs/$item_image'width=180' height='180'/>
					
            ";
    }
    
}





?>

＆＃13;

Answer 1

关于HTML的第一件事：

将<!DOCTYPE>更改为<!DOCTYPE html>

林38改变了 <input type="text" name="user_query" placeholder="Search a Product"/ >至<input type="text" name="user_query" placeholder="Search a Product" />

您还可以多次使用ID 猫 - ＆gt; id="cats"。在HTML中，每页只能有一个ID。它必须是独一无二的。

并且php函数中缺少</div>：

在该行<img src='admin_area/item_imgs/$item_image'width=180' height='180'/>之后添加此结束元素 - ＆gt; </div>

Answer 2

除了Simon的回答之外，您似乎还没有清除一些花车。据我所知，#sidebar和#content_area在#content_area内未被清除。在#content_area底部添加明确的修复程序应该可以解决问题。由于您在本地开发并且我们无法检查该代码，因此很难区分#content_area内的内容。
