当屏幕大于或等于 600px 宽（包括我的代码）时，如何使用媒体查询制作一个 600px 宽的表单？

Question

I'm thinking the following...

@media only screen and (min-width: 600px) {
.form {
width: 600px}
}

Am I correct?

You don't really need a media query for this. If you set the width at 600px and a max-width to prevent it exceeding 100% it will work.

 form { width: 600px; max-width: 100%; margin: 0 auto; }

 <form> <fieldset> <legend>Example Form</legend> <div> <label>Name<br /><input type="text" name="name" /></label> </div> <div> <button>Submit</button> </div> </fieldset> </form>
