When I was working on a phased project in college, I encountered a very strange phenomenon: kindEditor's function of uploading images failed, but it worked just fine after removing the styles referenced by jsp. This indicated that there was a problem with the styles, so I deleted a style and tested it. , so the culprit falls on zoom. This is the first time we "met each other". Today is the weekend, a rare leisure time. Let me summarize it now:
First, let’s talk about the role of zoom: zoom is used to set objects. Zoom attribute value: normal |
Code 1-1 is as follows:
<meta http-equiv="Content-type" content="text/html; charset=UTF-8"> <style type="text/css"> .test{zoom:normal;} </style> <h1 id="zoom">zoom</h1> <h1 id="zoom">zoom</h1> <h1 id="zoom">zoom</h1>Figure 1-1
Code 1-2 is as follows:
<meta http-equiv="Content-type" content="text/html; charset=UTF-8"> <style type="text/css"> .test{zoom:normal;} </style> <img src="/static/imghwm/default1.png" data-src="./test.png" class="lazy" style="max-width:90%" style="max-width:90%" alt="HTML CSS??zoom learning_html/css_WEB-ITnose" ><br> <img src="/static/imghwm/default1.png" data-src="./test.png" class="lazy" alt="HTML CSS??zoom learning_html/css_WEB-ITnose" ><br> <img class="test lazy" src="/static/imghwm/default1.png" data-src="./test.png" alt="HTML CSS??zoom learning_html/css_WEB-ITnose" >
Figure 1-2
Summary:
a. Figure 1-1: As can be seen from the code The font size of the first "zoom" is "5pt", the font size of the second "zoom" uses the default value, and the font size of the third "zoom" is added to the "zoom:normal;" style list;
b. Figure 1-2 From the code, you can see that the width of the first image is "50", the height is also "50" and the size is "5pt". The second image size uses the default value. The "zoom:normal;" style list has been added to the three pictures;
Through the description of points a and b, we can get the conclusion: n normal is used to make the element use its actual size;

Code 2-1 is as follows:
<meta http-equiv="Content-type" content="text/html; charset=UTF-8"> <style type="text/css"> .test{zoom:3;} </style> <h1 id="zoom">zoom</h1> <h1 id="zoom">zoom</h1>
Figure 2-1
Code 2-2 is as follows:
<meta http-equiv="Content-type" content="text/html; charset=UTF-8"> <style type="text/css"> .test{zoom:3;} </style> <img src="/static/imghwm/default1.png" data-src="./test.png" class="lazy" alt="HTML CSS??zoom learning_html/css_WEB-ITnose" ><br> <img class="test lazy" src="/static/imghwm/default1.png" data-src="./test.png" alt="HTML CSS??zoom learning_html/css_WEB-ITnose" >

Code 3-1 is as follows:
<meta http-equiv="Content-type" content="text/html; charset=UTF-8"> <style type="text/css"> .test{zoom:300%;} </style> <h1 id="zoom">zoom</h1> <h1 id="zoom">zoom</h1>
Figure 3-1
Code 3-2 is as follows:
<meta http-equiv="Content-type" content="text/html; charset=UTF-8"> <style type="text/css"> .test{zoom:300%;} </style> <img src="/static/imghwm/default1.png" data-src="./test.png" class="lazy" alt="HTML CSS??zoom learning_html/css_WEB-ITnose" ><br> <img class="test lazy" src="/static/imghwm/default1.png" data-src="./test.png" alt="HTML CSS??zoom learning_html/css_WEB-ITnose" >
Fig. 3-2
Note: Due to the defect of zoom compatibility, there are not many actual applications. Just a general understanding is enough.

在css中,可用list-style-type属性来去掉ul的圆点标记,语法为“ul{list-style-type:none}”;list-style-type属性可设置列表项标记的类型,当值为“none”可不定义标记,也可去除已有标记。

区别是:css是层叠样式表单,是将样式信息与网页内容分离的一种标记语言,主要用来设计网页的样式,还可以对网页各元素进行格式化;xml是可扩展标记语言,是一种数据存储语言,用于使用简单的标记描述数据,将文档分成许多部件并对这些部件加以标识。

在css中,可以利用cursor属性实现鼠标隐藏效果,该属性用于定义鼠标指针放在一个元素边界范围内时所用的光标形状,当属性值设置为none时,就可以实现鼠标隐藏效果,语法为“元素{cursor:none}”。

转换方法:1、给英文元素添加“text-transform: uppercase;”样式,可将所有的英文字母都变成大写;2、给英文元素添加“text-transform:capitalize;”样式,可将英文文本中每个单词的首字母变为大写。

在css中,rtl是“right-to-left”的缩写,是从右往左的意思,指的是内联内容从右往左依次排布,是direction属性的一个属性值;该属性规定了文本的方向和书写方向,语法为“元素{direction:rtl}”。

在css中,可以利用“font-style”属性设置i元素不是斜体样式,该属性用于指定文本的字体样式,当属性值设置为“normal”时,会显示元素的标准字体样式,语法为“i元素{font-style:normal}”。

在css3中,可以用“transform-origin”属性设置rotate的旋转中心点,该属性可更改转换元素的位置,第一个参数设置x轴的旋转位置,第二个参数设置y轴旋转位置,语法为“transform-origin:x轴位置 y轴位置”。
