Already shown in the previous 3D product display I have already mentioned how to make a cube, and there are numbers on it. Theoretically, it is more complicated than this, although it is not that cool~ I won’t go into details here.
CSS:
html { background: -webkit-radial-gradient(center, ellipse, #430d6d 0%, #000000 100%); background: radial-gradient(ellipse at center, #430d6d 0%, #000000 100%); height: 100%; } .stage { -webkit-perspective: 1000px; width: 20em; height: 20em; left: 50%; top: 50%; margin-left: -10em; margin-top: -10em; position: absolute; } .cube { position: absolute; width: 100%; height: 100%; -webkit-transform-style: preserve-3d; -webkit-transform: rotateX(-20deg) rotateY(-20deg); } .cube * { background: -webkit-linear-gradient(left, rgba(54, 226, 248, 0.5) 0px, rgba(54, 226, 248, 0.5) 3px, rgba(0, 0, 0, 0) 0px), -webkit-linear-gradient(top, rgba(54, 226, 248, 0.5) 0px, rgba(54, 226, 248, 0.5) 3px, rgba(0, 0, 0, 0) 0px); -webkit-background-size: 2.5em 2.5em; background-color: rgba(0, 0, 0, 0.5); position: absolute; width: 100%; height: 100%; border: 2px solid rgba(54, 226, 248, 0.5); -webkit-box-shadow: 0 0 5em rgba(0, 128, 0, 0.4); } .font { -webkit-transform: translateZ(10em); } .back { -webkit-transform: rotateX(180deg) translateZ(10em); } .left { -webkit-transform: rotateY(-90deg) translateZ(10em); } .right { -webkit-transform: rotateY(90deg) translateZ(10em); } .top { -webkit-transform: rotateX(90deg) translateZ(10em); } .bottom { -webkit-transform: rotateX(-90deg) translateZ(10em); }
Similarly: stage serves as the stage, cube sets the effect of the sub-element to 3d, then each face is rotated and translateZ is set to form a cube.
Set the backgroud for each surface and set the small grid code:
background: -webkit-linear-gradient( left, rgba(54, 226, 248, 0.5) 0px, rgba(54, 226, 248, 0.5) 3px, rgba(0, 0, 0, 0) 0px), -webkit-linear-gradient( top, rgba(54, 226, 248, 0.5) 0px, rgba(54, 226, 248, 0.5) 3px, rgba(0, 0, 0, 0) 0px); -webkit-background-size: 2.5em 2.5em;
Background settings, 3 pixel strips from left to right, from top to bottom Go to the 3 pixel bar below; then set the background size to 2.5em 2.5em, and then repeat the background, the effect is as follows (I added a border):
#The complete effect now:
You can see that the cube has been formed, just add animation at the end, no need I think the animation is very complicated, but it is actually very simple~
Define an animation frame:
@-webkit-keyframes spin { from { -webkit-transform: translateZ(-10em) rotateX(0) rotateY(0deg); transform: translateZ(-10em) rotateX(0) rotateY(0deg); } to { -webkit-transform: translateZ(-10em) rotateX(360deg) rotateY(360deg); transform: translateZ(-10em) rotateX(360deg) rotateY(360deg); } }
The name is spin, and it starts with translateZ(-10em) rotateX(0) rotateY(0deg); At the end: translateZ(-10em) rotateX(360deg) rotateY(360deg); That is, rotate 360 degrees around the x and y axes at the same time.
Finally add this animation attribute to our cube:
.cube { -webkit-animation: 6s spin linear infinite; position: absolute; width: 100%; height: 100%; -webkit-transform-style: preserve-3d; -webkit-transform: rotateX(-20deg) rotateY(-20deg); }
Set the time to animation time 6s, animation spin, speed to uniform linear, infinite loop infinite;
For more detailed parameter settings, you can refer to w3cSchool~ In the future, I will also write a separate blog introducing the properties of CSS3~
Okay, the final effect is complete~
For The original website looks slightly different:
Because it adds an extra radial gradient to each face, then we add:
.cube *:before { display: block; background: -webkit-radial-gradient(center, ellipse, rgba(0, 0, 0, 0) 30%, rgba(0, 128, 0, 0.2) 100%); background: radial-gradient(ellipse at center, rgba(0, 0, 0, 0) 30%, rgba(0, 128, 0, 0.2) 100%); content: ''; height: 100%; width: 100%; position: absolute; }

html5的div元素默认一行不可以放两个。div是一个块级元素,一个元素会独占一行,两个div默认无法在同一行显示;但可以通过给div元素添加“display:inline;”样式,将其转为行内元素,就可以实现多个div在同一行显示了。

html5中列表和表格的区别:1、表格主要是用于显示数据的,而列表主要是用于给数据进行布局;2、表格是使用table标签配合tr、td、th等标签进行定义的,列表是利用li标签配合ol、ul等标签进行定义的。

固定方法:1、使用header标签定义文档头部内容,并添加“position:fixed;top:0;”样式让其固定不动;2、使用footer标签定义尾部内容,并添加“position: fixed;bottom: 0;”样式让其固定不动。

HTML5中画布标签是“<canvas>”。canvas标签用于图形的绘制,它只是一个矩形的图形容器,绘制图形必须通过脚本(通常是JavaScript)来完成;开发者可利用多种js方法来在canvas中绘制路径、盒、圆、字符以及添加图像等。

html5中不支持的标签有:1、acronym,用于定义首字母缩写,可用abbr替代;2、basefont,可利用css样式替代;3、applet,可用object替代;4、dir,定义目录列表,可用ul替代;5、big,定义大号文本等等。

html5废弃了dir列表标签。dir标签被用来定义目录列表,一般和li标签配合使用,在dir标签对中通过li标签来设置列表项,语法“<dir><li>列表项值</li>...</dir>”。HTML5已经不支持dir,可使用ul标签取代。

html5是指超文本标记语言(HTML)的第五次重大修改,即第5代HTML。HTML5是Web中核心语言HTML的规范,用户使用任何手段进行网页浏览时看到的内容原本都是HTML格式的,在浏览器中通过一些技术处理将其转换成为了可识别的信息。HTML5由不同的技术构成,其在互联网中得到了非常广泛的应用,提供更多增强网络应用的标准机。

3种取消方法:1、给td元素添加“border:none”无边框样式即可,语法“td{border:none}”。2、给td元素添加“border:0”样式,语法“td{border:0;}”,将td边框的宽度设置为0即可。3、给td元素添加“border:transparent”样式,语法“td{border:transparent;}”,将td边框的颜色设置为透明即可。
