Question

这是我的网站：sanyigarazs.atw.hu

在“ Kapcsolat”页面上，有一个文本区域。

在Google Chrome浏览器中，它会调整为合适的大小，但是在某些浏览器（Edge，Mozilla）中，页面的其他元素比文本区域宽，这很烦人。

这是我的标记：

所以我想使textarea的大小等于其他元素（230像素），但是它仅在chrome浏览器中有效。

谢谢您的帮助，克里斯托夫。

Answer 1

首先，编辑您的HTML代码。

在您的HTML中删除textarea元素的size属性和input元素的width属性，因为它们无效。而且，您无需为size=20使用input，因为这是默认设置。

然后，像这样更改您的CSS：

input[type="text"],
textarea {
  width: 230px /* or you can use 100% */
  /* P.S. The resize option is not supported by Edge */
}

form { 
margin: 0 auto; 
width:240px;
font-size: 150%;
}

td {
    display: block;
    padding: 5px;
}

input[type="text"],
textarea {
  width: 230px
}

textarea {
    margin-top: 0%;
    resize: vertical;
}

#mobile {
    padding: 30px;
}

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(1.03);
} 

.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;
}

每个浏览器都有自己的预定义CSS样式表。要对其进行标准化，请使用“重置CSS”代码段。您可以在Google中找到一些代码。

将其放入reset.css文件中，并在包含mainn.css之前将其链接到头部。

html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
b, u, i, center,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, canvas, details, embed, 
figure, figcaption, footer, header, hgroup, 
menu, nav, output, ruby, section, summary,
time, mark, audio, video {
	margin: 0;
	padding: 0;
	border: 0;
	font-size: 100%;
	font: inherit;
	vertical-align: baseline;
}
/* HTML5 display-role reset for older browsers */
article, aside, details, figcaption, figure, 
footer, header, hgroup, menu, nav, section {
	display: block;
}
body {
	line-height: 1;
}
ol, ul {
	list-style: none;
}
blockquote, q {
	quotes: none;
}
blockquote:before, blockquote:after,
q:before, q:after {
	content: '';
	content: none;
}
table {
	border-collapse: collapse;
	border-spacing: 0;
}

为什么某些浏览器会自动“调整”页面上文本区域的大小？
