The style of y "Tweet" button disappears whem i adding !DOCTYPE html.当我添加 !DOCTYPE html 时,y“Tweet”按钮的样式消失了。
<!DOCTYPE html>
<html>
<head>
<title>Buttons</title>
<link rel="stylesheet" href="styles/buttons.css">
</head>
<body>
<button class="buttonYT">SUBSCRIBE</button>
<button class="JOIN">JOIN</button>
<button class="Tweetb">Tweet</button>
</body>
</html>
css part of Tweet button from button.css来自 button.css 的推文按钮的 css 部分
.tweetb {
background-color: rgb(29, 155, 240);
color: white;
border: none;
height: 36px;
width: 74px;
border-radius: 20px;
font-weight: bold;
font-size: 15px;
cursor: pointer;
margin-left: 8px;
transition: box-shadow 0.15s;
vertical-align: top;
}
.tweetb:hover {
box-shadow: 5px 5px 10px rgba(0, 0, 0, 0.15);
}
From your screenshot, the class name for the tweet button is TweetBT
, whereas in your button.css
it's .tweetBT
, which should be .TweetBT
.从您的屏幕截图中,推文按钮的类名是
TweetBT
,而在您的button.css
中是.tweetBT
,应该是.TweetBT
。
As the class name is not matching, the CSS is not applied.由于类名不匹配,因此不应用 CSS。 It's not an issue with !DOCType Html.
这不是 !DOCType Html 的问题。
