Question

因此，我想在页面上居中放置一个消息表单，但我不知道为什么，它如何起作用。我的html：

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title>Kapcsolat</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
    <link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Quicksand">
    <link rel="stylesheet" type="text/css" href="main.css">
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <div class="container">
        <nav class="navbar navbar-inverse navbar-fixed-top">
                <div class="container">
                    <div class="navbar-header">
                        <a href="index.html" class="navbar-brand">Sanyigarázs</a>
                    </div>
                    <div class="nav navbar-nav">
                        <li><a href="rolunk.html">Rólunk</a></li>
                        <li><a href="#">Kapcsolat</a></li>
                        <li><a href="weboldalrol.html">Weboldalról</a></li>
                    </div>
                    <!-- <form class="form-inline">
                        <input class="form-control mr-sm-2" type="search" placeholder="Ide írja keresését." aria-label="Keresés">
                        <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Keresés</button>
                    </form> -->
                </div>
        </nav>
        <div>
            <form id="uzenetes" action="emailtest.php" method="post">
                <table border="0">
                <tr>
                    <td>Név</td>
                    <td align="center"><input type="text" name="username"
                    size="20" maxlength="150" width="150"/></td>
                </tr>
                <tr>
                    <td>E-mail cím</td>
                    <td align="center"><input type="text" name="address"
                    size="20" maxlength="150" width="150"/></td>
                </tr>
                <tr>
                    <td>Tárgy</td>
                    <td align="center"><input type="text" name="subject"
                size="20" maxlength="150"/></td>
                </tr>
                <tr>
                    <td>Üzenet</td>
                    <td><textarea id="message" name="message" placeholder="Ide írja üzenetét..."  size="20" maxlength="150"></textarea></td>
                 </tr>
                    <td colspan="2" align="center"><input id="button" type="submit"
                    value="Elküldés"/></td>
                </tr>
                </table>
            </form>
        </div>
    </div>

</body>
</html>

我的css是：

    form { 
        margin: 0 auto; 
        width:250px;
        margin-top: 15%;
        }

和

body {
    font-family: 'Quicksand', sans-serif;
}
.thumbnail {
    transition: all 0.2s;
}
.thumbnail:hover {
    transform: scale(1.1);
}
p {
    text-align: center;
}
.jumbotron {
    border: 1px solid black;
}
.tested {
    font-size: 140%;
}
.bug {
    padding: 15px;
    border-top: 1px solid black;
}
.navbar-inverse {
    transition: all 0.2s;
}
.navbar-inverse:hover {
    transform: scale(1.1);
} 
.weboldalroltext {
    padding-bottom: 3px;
}
body { 
padding-top: 70px; 
}
.mainHeader {
    padding-bottom: 50px;
}
.navbar {
    padding-top: 5px;
    font-size: 20px;
}
.navbar-brand {
    font-size: 20px;
}
a:after {
    display: block;
    content: '';
    border-bottom: solid 3px #fff;
    transform: scaleX(0);
    transition: transform 250ms ease-in-out;
    padding: 5px 0px 0px 0px;
  }
  a:hover:after {
    transform: scaleX(1);
  }
.helloka {
    width: 300px;
    font-size: 25px;
}
hr {
    height: 10px;
    border: 0;
    box-shadow: inset 0 12px 12px -12px rgba(0, 0, 0, 0.5);
}
form {
    padding-left: 80%;
    padding-top: 10px;
    width: 150%;
}
h5 {
    font-size: 18px;
}

我在设计方面有点不好，所以如果我在CSS代码中做过糟糕的事情，请不要生气。所以我想要的是将#uzenetes表单居中放在屏幕上。感谢您的帮助，克里斯托夫。

从<div class="info"> <label for="input">Stream</label> <input id="input" type="text" name="someNameHere" value="http://hi5.1980s.fm/;" /> <input id="sent" type="submit" value="Set" /> </div> sent.addEventListener("click", function(evt) { player.src = value.value; player.volume = 1.0; });中删除width: 150%;和padding-left: 80%;。因为您已经在下面创建了第二个表单CSS。

form

 form { 
        margin: 0 auto; 
        width:250px;
        margin-top: 15%;
        }

body {
    font-family: 'Quicksand', sans-serif;
}
.thumbnail {
    transition: all 0.2s;
}
.thumbnail:hover {
    transform: scale(1.1);
}
p {
    text-align: center;
}
.jumbotron {
    border: 1px solid black;
}
.tested {
    font-size: 140%;
}
.bug {
    padding: 15px;
    border-top: 1px solid black;
}
.navbar-inverse {
    transition: all 0.2s;
}
.navbar-inverse:hover {
    transform: scale(1.1);
} 
.weboldalroltext {
    padding-bottom: 3px;
}
body { 
padding-top: 70px; 
}
.mainHeader {
    padding-bottom: 50px;
}
.navbar {
    padding-top: 5px;
    font-size: 20px;
}
.navbar-brand {
    font-size: 20px;
}
a:after {
    display: block;
    content: '';
    border-bottom: solid 3px #fff;
    transform: scaleX(0);
    transition: transform 250ms ease-in-out;
    padding: 5px 0px 0px 0px;
  }
  a:hover:after {
    transform: scaleX(1);
  }
.helloka {
    width: 300px;
    font-size: 25px;
}
hr {
    height: 10px;
    border: 0;
    box-shadow: inset 0 12px 12px -12px rgba(0, 0, 0, 0.5);
}
form {  
    padding-top: 10px;
}
h5 {
    font-size: 18px;
}
