如何在文本周围添加一个小框？

Question

我有以下代码：

// Preloader
 $(window).on('DOMContentLoaded', function() {
    if ($('#preloader').length) {
      $('#preloader').delay(1000).fadeOut('slow');
    }
});

* {
    padding: 0;
    margin: 0;
    box-sizing: border-box;
}

@import url('https://fonts.googleapis.com/css2?family=Montserrat+Alternates:wght@500;700&family=Montserrat:wght@400;600&family=Oswald:wght@500&family=Pacifico&family=Roboto:ital,wght@0,400;0,900;1,500&display=swap');

#preloader {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  z-index: 9999;
  overflow: hidden;
  background: white;
   display: flex;
    justify-content: center;
    align-items: center;
}


.svg-file path {
    fill: transparent;
    stroke-width: 3;
    stroke: rgb(1, 36, 133);
}

.svg-file.z-logo path {
    stroke-dasharray: 550;
    stroke-dashoffset: 0;
}

.svg-file.z-logo path {
    animation: animate-zlogo 3s linear infinite;
}

svg {
    filter: drop-shadow(2px 2px 3px rgba(0, 0, 0, 1));
    transform: scale(2);
}

.svg-file h2 {

    transform: translate(0, 50px) skewX(-210deg) rotate(-6deg);
    font-size: 3em;

}

.svg-file span {
    animation: dots 2.5s steps(6, end) infinite;
    font-size: 5em;
    display: block;
    transform: translate(0, 65px) skewX(-210deg) rotate(-6deg);
    background-color: rgb(5, 46, 80);

    40% {

    }

    60% {

我想在它周围添加一个小框，以便更好地向您展示我正在寻找什么样的输出，那么我想要这个：

所以，我现在缺少的是黑色的background box，我不希望牛被page cover 填充，它的高度和宽度应该与上图大致相同。将其视为网站的预加载器。在页面中间，一个带有h 徽标的中小型框显示在里面，就像上面显示的那样。

注意：动画应该在盒子里面，不应该在盒子外面，所以当你运行上面的代码时，动画应该在黑盒子里。我只是在寻找有关如何准确设置盒子尺寸的帮助，如图所示。我稍后会调整测量值，但现在我正在寻找要显示的框的输出。

我尝试使用与之前提出类似问题的人相同的逻辑，但它不起作用，它给了我一个黑屏，这不是我想要的。我希望整个屏幕为white，但如上图所示，此图像的背景框为黑色。

预期输出：

动画应该在inside盒子里完美地运行，正如你所见，盒子在屏幕中间，屏幕上有一个whitebackground。

Answer 1

您在 .svg-file div 上设置黑色背景...并将 svg 缩放到 0.66 (2/3)。

// Preloader
 $(window).on('DOMContentLoaded', function() {
    if ($('#preloader').length) {
      $('#preloader').delay(2000).fadeOut('slow');
    }
});

* {
  padding: 0;
  margin: 0;

使用 ::before 伪

// Preloader
$(window).on('DOMContentLoaded', function() {
  if ($('#preloader').length) {
    $('#preloader').delay(1000).fadeOut('slow');
  }
});
