网页设计基础之CSS（三） 1.CSS的盒子模型 ①盒子模型的初步认识 Margin(外边距) - 与其它盒子的距离 Border(边框) - 手机盒子的厚度 Padding(内边距) - 填充泡沫的厚度 Content(内容) - 内容注意：虽然盒子模型拥有外边距，边框，外边距，宽和高这些基本属性，但是并不要求每个元素都必须定义这些元素 ②盒子模型的相关属性边框属性 1.样式综合设置： border-style:上边右边下边左边注意边框的顺序、如果样式为nomal或没有时，后续不可加属性 border-style的复合书写形式：上边左右边下边；上下边左右边；上下左右边 2.设置边框宽度： border-width：上边宽度右边宽度下边宽度左边宽度注意边框的顺序 3.设置边框颜色： border-color：上边颜色右边颜色下边颜色左边颜色注意边框的顺序边框透明色： transparent 或者 border-color：transparent 内边距属性 padding：上内边距右内边距下内边距左内边距 padding的相关属性的取值可为auto自动外边框属性当对块级元素应用宽度属性width，并将左右的外边距都设置为auto时，可使块级元素水平居中 .header { width : 100px ; margin : 0 auto

JButton JBtn=new JButton("sdfd"); JBtn.setBorder(BorderFactory.createLineBorder(Color.CYAN,5)); JBtn.setBackground(Color.GREEN); JBtn.setMargin(new Insets(5,5,10,10)); Any advice? 回答1: The borders are part of the button and

Indexing into arrays of arbitrary rank in C#

阅读更多关于 Indexing into arrays of arbitrary rank in C#

问题 I need to iterate over an array of arbitrary rank. This is for both reading and writing, so GetEnumerator will not work. Array.SetValue(object, int) doesn't work on multidimensional arrays. Array.SetValue(object, params int[]) would require excessive arithmetic for iterating through the multidimensional space. It would also require dynamic invocation to get around the params part of the signature. I'm tempted to pin the array and iterate over it with a pointer, but I can't find any

pytorch中池化层MaxPool2d函数

阅读更多关于 pytorch中池化层MaxPool2d函数

对于输入信号的输入通道，提供2维最大池化（max pooling）操作 class torch . nn . MaxPool2d ( kernel_size , stride = None , padding = 0 , dilation = 1 , return_indices = False , ceil_mode = False ) 参数kernel_size，stride, padding，dilation数据类型：可以是一个int类型的数据，此时卷积height和width值相同; 也可以是一个tuple数组（包含来两个int类型的数据），第一个int数据表示height的数值，tuple的第二个int类型的数据表示width的数值参数： kernel_size(int or tuple) - max pooling的窗口大小 stride(int or tuple, optional) - max pooling的窗口移动的步长。默认值是kernel_size padding(int or tuple, optional) - 输入的每一条边补充0的层数 dilation(int or tuple, optional) – 一个控制窗口中元素步幅的参数 return_indices - 如果等于True，会返回输出最大值的序号，对于上采样操作会有帮助 ceil

Data Format is as such: 123 Pie Crust Struct1 a is stored as 3 separate parameters. However, struct2 is two separate parameters with both 2nd and 3rd line stored to the char str[] . The problem is when

web前端入门到实战：内边距属性、外边距属性

阅读更多关于 web前端入门到实战：内边距属性、外边距属性

一、内边距属性 1.定义：边框和内容之间的距离就是内边距 2.分开写 padding-top:数字px； padding-left:数字px； padding-bottom:数字px； padding-right:数字px； 3.连写： padding：上右下左； 4.注意点：（1）给标签设置内边距之后，标签占有的宽度和高度会发生变化（2）内边距也会有背景颜色 web前端开发学习Q-q-u-n： ⑦⑧④-⑦⑧③-零①②，分享学习的方法和需要注意的小细节，不停更新最新的教程和学习方法（详细的前端项目实战教学视频） <style> div{ font-size: 25px; width:100px; height: 100px; border: 1px solid red; background-color: green; } .box1{ padding-top:20px; } .box2{ padding-left: 30px; } .box3{ padding-bottom: 40px; } .box4{ padding-right:50px; } .box5{ padding:40px 60px 70px 80px; } </style> <body> <div class="box1">我是段落一</div> <div class="box2">我是段落二</div
