我当时正在做一个项目，其中包含一个搜索框，该搜索框用数据库中正确的查询来回响一个格式整齐的图像字符串。然而，在使用flexbox css的迷宫中，我成功地结束了：a它逃离了我的屏幕，b每个项目的s没有上下空格：(
这是我的代码：

<div id= "searchresults" style="width: 100vw; padding-bottom: 3vh; padding-top: 3vh; min-height: 10vh; height: auto; background-color:  #e7e7e7 ; display: flex; flex-wrap: wrap; align-content: space-between; justify-content: space-between;">
<?php
//Makes connection
include 'dxbase.php';
$conn = new mysqli($servername, $username, $password, $dbname);

if(isset($_POST["search"])){
$tempvardf = '%'.$_POST['search'].'%'; #############
//Defines SQL command to bring up data about the products matching the set search
$sql = "SELECT id, name, price, location, path FROM products WHERE name LIKE ?;"; #'%$_POST[search]%'
//Create a prepared statement
$stmt = mysqli_stmt_init($conn);
//Prepare the prepared statement
if (!mysqli_stmt_prepare($stmt, $sql)) {
    echo "SQL STATEMENT FAILED... OOF";
} else {
    //Bind paramaters to placeholder
    mysqli_stmt_bind_param($stmt, "s", $tempvardf);
    //Run paramaters inside database
    mysqli_stmt_execute($stmt);
    $result = mysqli_stmt_get_result($stmt);

    while ($row = mysqli_fetch_assoc($result)) {
        echo  "<div style='background-color: blue; padding: 1vw; width: 30vw; display: flex; flex-direction: column; align-content: space-between;'>";

        if(isset($row['path'])){
        echo "<img style='width: 28vw; height: 28vw; ' src=". $row['path'].">". "<br>";

        } else {
            echo "can't access image path";
        }
        echo $row['name']."<br>";
        echo "<s><i>".$row['price']."</i></s><br>"; #CHANGE THIS ONE TO ORIGINAL NONDISCOUNTED PRICE
        echo $row['price']."<br>";
        echo "</div>";
    }
    #echo "And that's it!";
}

} else {

}

?>
</div>

以下是所要求的css：

    font-family: "Lato", sans-serif;

.sidenav {
    height: 100%;
    width: 0;
    position: fixed;

    font-size: 25px;
    color: #818181;
    display: block;

}

/* Position the "next button" to the right */

}

/* On hover, add a black background color with a little bit see-through */
.prev:hover, .next:hover {
  background-color: rgba(0,0,0,0.8);
}

/* Caption text */
.slideshowtext {
  color: #f2f2f2;
  font-size: 15px;
  padding: 8px 12px;
  position: absolute;
  bottom: 8px;
  width: 100%;

.dot {

  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  transition: background-color 0.6s ease;
}

.active, .dot:hover {
  background-color: #717171;
}

/* Fading animation */
.fade {
  -webkit-animation-name: fade;
  -webkit-animation-duration: 1.5s;
  animation-name: fade;
  animation-duration: 1.5s;
}

@-webkit-keyframes fade {
  from {opacity: .4} 
  to {opacity: 1}
}

@keyframes fade {
  from {opacity: .4} 
  to {opacity: 1}
}

/* On smaller screens, decrease text size */
@media only screen and (max-width: 300px) {
  .prev, .next,.text {font-size: 11px}
}

只是澄清一下，这确实有效，而且我的数据库正确地响应了我的测试值，但不幸的是，数小时的努力试图破解一堵复杂的css墙却毫无结果。

有什么建议吗？
