Everything was working correctly when I did not have routes, but now every time I go to /home, I get this error. Refused to load the font 'data:font/woff;base64,d09GRgABAAAAAIw4ABEAAAABQcAAAQABAAAAAAAAAAAAAAAAAAAAA…hgZiCKVViwAiVhsAFFYyNisAIjRLMJCgMCK7MLEAMCK7MRFgMCK1myBCgGRVJEswsQBAIrAA==' because it violates the following Content Security Policy directive: "default-src 'self'". Note that 'font-src' was not explicitly set, so 'default-src' is used as a fallback. I am

I want to understand why the following happen. Starting with this example: A <p> element without any special CSS rule on it has no text when the page is loaded, therefore height:0 . Due to javascript operations in the page, it starts having characters, thus the height is set to the default font-size , which allow us to see the text. How can I assure that this <p> has always the same height (with or without text inside it)

图片验证码工具类 文章 https://blog.csdn.net/lzxlfly/article/details/93381526 需求 session中放入登录验证码，一定时间后定时清除。 每次使用过验证码后清除，需要重新生成验证码。 工具类 package com.yuantiao.smartcardms.util; import javax.imageio.ImageIO; import java.awt.*; import java.awt.image.BufferedImage; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import java.util.Random; public class CaptchaCodeUtil { public static void main(String[] args) throws IOException { // CaptchaCodeUtil captchaCodeUtil = new CaptchaCodeUtil(); // captchaCodeUtil.createImageCode("changhe"); // captchaCodeUtil.write(new

今天我们将利用 tkinter 库制作以下的登录界面, 可以实现登录，并可以实现注册和登录，这里为了简单起见，使用 json 文件保存读取用户账号和密码 创建根窗口 首先，我们需要建立一个根窗口，控制其不能够缩放并设置其标题，调用 mainloop 方法来控制 from tkinter import * window = Tk ( ) # 建立根目录 window . title ( "Welcome" ) # 设置标题 window . geometry ( "500x400" ) # 设置窗口的大小 window . resizable ( width = False , height = False ) # 设置窗口不能够缩放 window . mainloop ( ) 到此，我们运行一下，便可以得到如下的效果 添加图片 然后我们来设置一下首页中图片，利用 PIL 和 Canvas 中的 create_image 方法加上控制一下位置，我们便可以实现，代码如下： from PIL import Image , ImageTk # 首页的图片 image = Image . open ( "./welcome.jpg" ) # 打开图片，保存在image对象中 img = ImageTk . PhotoImage ( image ) # 转化成tkinter中的图片对象 c =

尽管绝大多数人都知道inherit这个关键字，但是很容易遗忘，inherit可以用在任何css属性中，而且它总是绑定到父元素的计算值 举例来说，要把表单元素中的字体设置为与页面的其他部分相同，你并不需要重复指定字体属性，只需要利用inherit的特性即可 input ， button { font: inherit; } 与此类似，要把超链接的颜色设定为与页面中其他文本相同，还是可以用inherit a { color: inherit; } 来源： https://www.cnblogs.com/lilei-site/p/11785287.html

I was thinking of using java.awt.Font.createFont(int fontFormat, InputStream fontStream) and then building org.eclipse.swt.graphics.FontData and org.eclipse.swt.graphics.Font objects out of AWT java.awt.Font object. Since I haven't tried that option yet (I

It appears that the way to do this is to use IDWriteTextLayout::SetTypography to set an IDWriteTypography object to the layout which contains the various ligature-related font features with a value of zero to disable them. That works to disable the ligatures, but it also affects (disables) other typography settings that I don't want to mess with, such as kerning. After some experimentation, it turns out that I could
