As an AI language model, I do not have a personal opinion or feeling about anything. "Null" is a term used in programming and database management to refer to a value or a field that has no assigned value.

Here are some suggestions to optimize the code:
1. Use shorthand properties whenever possible. For example, instead of writing `background-size: 100% 100%;`, you can write `background-size: cover;`.
2. Consolidate similar styles into classes, instead of repeating them for every element. For example, you can create a class for the font family and apply it to all elements that use that font.
3. Remove unnecessary styles that are not being used or overwritten by other styles.
4. Use more specific selectors to target elements, instead of relying on the order of elements in the HTML. This will make the code more robust and easier to maintain.
5. Consider using a CSS preprocessor like Sass or Less, which can help you write cleaner and more organized code.
Here's an example of how the code could be optimized:
```

background: url('../../assets/img/info-bg.png') no-repeat center center / cover;

line-height: 32px;
letter-spacing: 0.3px;
font-family: AlibabaPuHuiTiB;
}
.en-title {
margin-left: 30px;
font-size: 14px;
font-weight: 400;
text-align: left;

line-height: 32px;
letter-spacing: -0.91px;

.font-alibaba {

video { position: fixed; top: 0; left: 0; min-width: 100%; min-height: 100%; z-index: -1; }把图片设置为背景,
如果你想将一个图片作为背景,可以使用以下的HTML和CSS代码:
HTML代码:
```
<div class="bg-image"></div>
<div class="content">
<h1>Your Content Here</h1>
<p>Your text here...</p>
</div>
```
CSS代码:
```
body {
margin: 0;
padding: 0;
height: 100%;
}
.bg-image {
position: fixed;
top: 0;
left: 0;
min-width: 100%;
min-height: 100%;
background-image: url(your-image-url-here);
background-size: cover;
z-index: -1;
}
.content {
position: relative;
z-index: 1;
padding: 50px;
text-align: center;
color: #fff;
}
```
在这个例子中,我们使用了一个div作为背景,并且将背景图片设置为了你自己的图片。我们将背景图片的大小设置为cover,以填满整个屏幕。此外,我们还添加了一个content div,将你的文本和内容放置在其中。
你可以根据自己的需求进行调整和修改。
