This property also includes direction/text-align/text-indent/float/overflow/position ... Wait a m

I checked the code carefully and couldn't find anything wrong. There is no way, I can only check error correction like normal, try to change the code in the CSS. When I changed the code in the hover pseudo-class link (as shown in the c

As we all know, fixing bugs are essential for all software projects in the future. Some unexpected problems exist for programmers when a software is delivered to a customer or handed over to a tester for testing. There are mature bug tracking systems, such as bugzero, bugzilla, and redmine.Solving bugs is a headache. It is generally caused by the following reasons:(1) design defects;(2) not fully considered

don't even care if others want to use these functions. Unfortunately, as a Team Project, users of this software cannot be limited to myself, and we also need to consider other target users. It's easy to write software for myself. I just need to use it myself. It's nice. User Experience is good. It doesn't matter if I don't care for myself. However, considering that this is a Team Project for other users at the same time, there are more things: good looking, there is enough prompt information, a

Many years of testing experience often finds that some bugs cannot be fixed smoothly. These bugs often have four steps: 1. It was finally solved in the detected version, but it took more than a week in the middle. 2. Planned solutions will be implemented in subsequent versions. 3. I decided to never fix it, but it turned into a potential bomb and was forced to fix it in subsequent versions. 4. I decided to

During the software testing process, different people often test the same project, so repeated bug submission may occur, affecting the entire project and personnel: This wastes the time and effort of testers and affects the testing progress. A waste of time for developers to repeat bugs If a developer calculates performance based on the number of bugs, the relationship between the develop

the bugs in the program. You can demonstrate it yourself, or you can give detailed steps that can lead to an error in the program. If the program goes wrong, the programmer collects additional information until it finds the cause of the error, and if the program does not go wrong, then they will ask you to continue to focus on the issue and gather relevant information.In the bug report, try to figure out what the facts are (ex: "I'm on the computer"
