height.
Therefore, if the resolution is 1024, it is better to set your webpage to 1000 security. As shown in the following figure, the white space on both sides is larger, making it more visual and convenient to design floating layers.
Generally, the resolution is set to 800 for 770. But it is also set to 760.
These need to be understood and kept in mind, otherwise it is likely that they do not meet the requirements of the browser, But we generally set back a little smaller, the width of Some b
average score is increased. However, if it is not good, someone will always give a negative review, and the result will lead to a high standard deviation. For example, if there are 100 comments in total, 50 4 stars and 50 5 stars, the expected mathematical value is 4.5 stars and the standard deviation is 0.5. However, if there are 100 comments, the average score is 4.5, but for 25 3 stars and 75 5 stars, the standard deviation is 0.86. Even if you don't trust the latter, you may feel worse than
Performance can be understood as an indicator. In a certain environment, the system responds within a certain period of time.
L performance from the user's perspective
Response time of the software to user feedback. Note: If a user obtains a large amount of data, it will take a lot of time, but it takes a long time for the user to optimize data presentation (for example, to operate 1000 data records in the background, you can present 10 records first, and the other
is likely that they do not meet the requirements of the browser, But we generally set back a little smaller, the width of Some browsers with plug-ins or other things may change. Therefore, the resolution of 800 is generally set to around 760, and the resolution of 1024 is set to around 990.
In this way, I use guides and scales to divide the approximate range. Note that my division is exactly 770, and 1000. The website I want to do is at a resolu
