Sure. Just apply the style to these CSS rules:
当然。只需将样式应用于这些 CSS 规则：
::-webkit-input-placeholder {
font-style: italic;
}
:-moz-placeholder {
font-style: italic;
}
::-moz-placeholder {
font-style: italic;
}
:-ms-input-placeholder {
font-style: italic;
}
Probably not all of these rules are needed. I always just reference CSS Tricksbecause I always forget how to do it.
可能不需要所有这些规则。我总是只引用CSS Tricks，因为我总是忘记如何去做。
Edit:Note that these rules cannot be combined into one selector. They must be declared separately as noted by Dave Kennedyin the comments below.
编辑：请注意，这些规则不能合并为一个选择器。正如Dave Kennedy在下面的评论中所指出的，它们必须单独声明。

Another way: the :focus selector is your friend. To make it only for the placeholder use the :not selector. This have the CSS rule only if the input field is NOT current selection. Define in your CSS :
另一种方式： :focus 选择器是你的朋友。要使其仅用于占位符，请使用 :not 选择器。仅当输入字段不是当前选择时才具有 CSS 规则。在你的 CSS 中定义：
.class-of-your-input-field:not(:focus) {
font-style:italic;
}
