php - 使用 CSS 对齐图像

Question

我有一个 HTML 输入，用于在 MySQL 表中搜索元素。我必须说我是 CSS 的新手。这是 HTMP 部分:

<div id="main">


        <div class="icon"></div>
        <h1 class="title">Especialidad Médica</h1>
        <h5 class="title">(selecciona la especialidad médica del doctor)</h5>

        <!-- Main Input -->
        <input type="text" id="search" autocomplete="off">

        <!-- Show Results -->
        <h4 id="results-text">Mostrando resultados para: <b id="search-string">Array</b></h4>
        <ul id="results"></ul>


    </div>

这是 CSS 部分:

我正在使用 AJAX 从 PHP 文件中获取结果。

这是 PHP 部分:

// Define Output HTML Formating
$html = '';

$html .= '<li class="result">';
$html .= '<img src="iconos_especialidades/logo"  width="94" height="94"  />';
$html .= '<a target="_blank" href="urlString">';
$html .= '<h3>nameString</h3>';
$html .= '</a>';
$html .= '</li>';

// Get Search
$search_string = preg_replace("/[^A-Za-z0-9]/", " ", $_POST['query']);
$search_string = $tutorial_db->real_escape_string($search_string);

// Check Length More Than One Character
if (strlen($search_string) >= 1 && $search_string !== ' ') {
    // Build Query
    $query = 'SELECT * FROM tb_especialidades WHERE especialidad LIKE "%'.$search_string.'%" OR especialidad LIKE "%'.$search_string.'%"';

    // Do Search
    $result = $tutorial_db->query($query);
    while($results = $result->fetch_array()) {
        $result_array[] = $results;
    }

    // Check If We Have Results
    if (isset($result_array)) {
        foreach ($result_array as $result) {

            // Format Output Strings And Hightlight Matches
            $display_function = preg_replace("/".$search_string."/i", "<b class='highlight'>".$search_string."</b>", $result['especialidad']);
            $display_name = preg_replace("/".$search_string."/i", "<b class='highlight'>".$search_string."</b>", $result['especialidad']);
            $display_url = 'opinar_doc_local.php';

            if ($result['icono'] == ""){
            $display_logo = "nada.jpg";
            }
            else {
            $display_logo = $result['icono'] ;
            }

            // Insert Name
            $output = str_replace('nameString', $display_name, $html);



            // Insert URL
            $output = str_replace('urlString', $display_url, $output);
            // Insert LOGO
            $output = str_replace('logo', $display_logo, $output);

            // Output
            echo($output);
        }
    }else{

        // Format No Results Output
        $output = str_replace('urlString', 'javascript:void(0);', $html);
        $output = str_replace('nameString', '<b>No se ha encontrado la especialidad buscada.</b>', $output);
        $output = str_replace('functionString', 'Sorry :(', $output);

        // Output
        echo($output);
    }
}

我的问题是我想在 div 的左侧获取图像，在图像的右侧获取文本，文本应垂直对齐到图像的中间。

也就是当前的输出:

我已经尝试将其添加到 CSS 文件中:

img {
    vertical-align: middle;
}

但是输出是一样的。

Answer 1

试试这个，如果添加 display-inline-block; and vertical-align: middle;在图像和 <h3> 上然后图像和<h3>将在彼此中间，但请记住一件事，您需要在两者上添加宽度才能使其正常工作。

ul#results li img{display: inline-block; vertical-align:middle;}
ul#results li h3{display: inline-block; vertical-align:middle;}

<ul id="results">
  <li>
    <img src="http://www.redsignal.net/staging/wp-content/uploads/2015/12/6_ui_ux_design_hov.png"/>
    <h3>  your txt her </h3>
      </li>
  </ul>
