这里是连接.php
class DBConnection{
static protected $db;
function __construct(){
if(self::$db = new PDO(DBCON, USR,PSW)){
echo 'true';
}else{
// echo 'error';
}
}
}
$db = new DBConnection();
和css是
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
.row{
width: 100%;
height: 100%;
/* border: .5px solid ; */
}
.flex-row{
display: flex;
flex-direction: row;
width: 100%;
height: 100%;
}
.half-size{
width: 50%;
/* border: 1px solid; */
height: 100%;
}
.form{
text-align: center;
display: flex;
justify-content: center;
height: 100%;
flex-direction: column;

}
form{
/* border: 1px solid; */
margin-left: 20%;}
.input{

flex-direction: column;

}

box-shadow: 0px 2px 10px 1px #3ca6d8;
}
.form-wrapper{

.bgc{

每次我删除require_once 'Connection.php';我的css开始变得疯狂。
