This is one I saw a short time ago, was still in response to the layout of distress, but learned this, feel much easier. Flex Layout TutorialPage layout is a key application of CSS.The traditional solution for layout, based on the box model, depends on the Display property + Position property + Float property. It is very inconvenient for those special layouts, for example, vertical centering is not easy to achieve.In 2009, the website proposed a new s
view to define a position based on the relative relationship between different views in the layout.The goal of Constraintlayout is to help reduce the number of nested views, which can improve the performance of layout files. The layout class also makes it easier to define layouts than when using relativelayout, because we can now pin any side of one view to the other, without having to prevent the entire view from going to any other side.For example,
According to the CSS3 specification, the viewport units consist mainly of the following 4:
VW:1VW equals 1% of viewport width
VH:1VH equals 1% of the viewport height
Vmin: Choose the smallest of VW and VH
Vmax: Pick the biggest one in VW and VH
Measured in viewport units, viewport width 100vw, height 100vh (vertical screen on the left, horizontal on the right)For example, in the desktop-side browser viewport size is 650px, then 1VW = 650 * 1% = 6.5px (This is theoretica
The Android interface has a layout and components that work together, and the layout is like a frame in a building, and the component is equivalent to the bricks and mortar in the building. The components are arranged in order according to the layout requirements and form the interface that the user sees. Android's five major layouts are linearlayout (linear layout), Framelayout (single frame layout), relativelayout (relative layout), Absolutelayout (
Find the private channel for the VPN Intranet to log on to the Internet. The author is located in a branch. There are two network lines, one is frame relay to the headquarters of the company, and the other is the normal ADSL bandwidth, only 512 K. The entire branch uses the K broadband Internet shared by each user, the available bandwidth becomes very small, and the network application experience is not smooth. I have heard that the Internet egress ba
NAT analysis (intranet users access the server through domain names) 1. environment hypothesis: the private network address of the Intranet server is 192.168.2.20., port 80 of the server is mapped to port 80 of port 202.101.1.1, and the domain name www.sina.com is applied. The IP address of the Intranet PC is 192.168.2.2, now we configure the following command on
Sandbox), also known as Sandbox, is one of the most widely used technologies in the information security field in recent years. Google Chrome and MS Office2010 all use sandbox technology to improve their security. In the current IT field, Sandbox technology is widely used in the anti-virus software industry. For example, IT is used for virus experiments and various sandbox Security modes in user applications.
So what is sandbox technology? Simply put, sandbox is an "environment" that provides a

If the message is true, then the user with the intranet IP address can be completely through the router settings to solve the remote access and management problems.Is the message true?According to small understanding, early in 2013, the peanut shell has been resolved in the
To protect Intranet security, I believe that firewall programs are installed on the Intranet of the vast majority of organizations. As a result, the idea of many network administrators attempting to remotely control the Intranet workstation on the internet is forcibly "contained. This is not the case. Because my local network is installed with a firewall and only

In the development, sometimes we need to send remotely, or through 3G and 4G, or other WiFi environment to send a small amount of data, and do not want to spend so much cost to develop a cloud server, this time the emergence of a router to expose an intranet IP for external network access. In fact, the implementation name of this method is called port mapping .

The idea of Intranet penetration is derived from the idea of Trojan horse-bastion hosts are the easiest way to break through from the inside. A large website, a large company, a large target, and an external target, administrators will always do everything they can to strengthen prevention and fix vulnerabilities. It is almost impossible to use conventional methods.
