Web designers can use fonts to fully reflect the emotions to be expressed in the design. Font selection is a kind of emotional and intuitive behavior. However, no matter What font you select, you must follow the overall idea of the web page and the needs of the browser. For example, the bold Chinese cha

We recommend that you use lbs as the unit for pixel-based printing.The most suitable font size for webpage text display is about 12 lbs. Many comprehensive websites now use a 9 lb font size because there are many contents to be arranged o

What makes the code "better"
Basic theorem of readability
The code should be written so that others can understand the time it takes to minimize it.
Is it always as small as possible?

Designing react components still takes a lot of time, because the readability of the jsx is poor. Another bad thing is that you can't use normal if statements in your HTML code. React's loyal users will tell you that with ternary operations, there is no need to use conditional judgment. But I assure you that when you read or edit the code again, yo
1. Definition Introduction(1). XML definitionThe Extensible Markup Language (extensible Markup Language, XML), which is used to tag electronic files with a structured markup language that can be used to tag data, define data types, is a source language that allows users to define their own markup language. XML uses the DTD (document type definition) document type definition to organize the data, a unified format, cross-platform and language, and has long been recognized as a standard in the indu
. So you have to provide an exception handling mechanism to enhance the robustness and fault tolerance of your program. How do I do exception handling? First of all, the exception is caused by a program error, grammatical errors are not related to exception handling, must be corrected before the program runs.

A reference is syntactically a value variable but has the semantics of a pointer.
The input parameter is a value parameter or a const reference, and the output parameter is a pointer. The input parameter can be a const pointer, but must not be a non-const reference parameter, exc

1.1 XML definition
The Extensible Markup Language (extensible Markup Language, XML), which is used to mark an electronic file with a structured markup language, can be used to mark data, define data types, and is a source language that allows users to define their own markup language. XML organizes data using the DTD (document type definition) document types definition, which has long been recognized by the industry as a standard for consistency, cross-platfor
In order to standardize program code writing, improve the readability of the code, reduce maintenance costs, improve office efficiency, the proposed program in the following several specifications:
First, the Unified VBScript and ASP program writing specifications:
(i) Variable naming rules:
Since it is not necessary to declare variables in ASP and VBScript, and not to declare the types of variables, in order to improve the
many "homemade" web pages, the most common problem is that the contrast between the title and the body font is low, and the information level of the entire page is not obvious. Just adjusting the font size is not enough to make a comparison, the header font should be heavier than the text, that is, the font should be thicker, make sure they are conspicuous enough to be more easily noticed by the eyes.

temporary variables been renamed to more meaningful names? When the Boolean variable is true, can the variable express its meaning exactly? The names in the enumeration contain prefixes or suffixes that can represent their classes. A named constant is named according to the abstract entity it represents, not the number it represents. Naming rules can distinguish between local data, class data, and global data. Rules can distinguish between type names, named constants, enumeration types, and var
For testing, writing assertions seems simple: we only need to compare results to expectations, usually using the assertion method, such as the Asserttrue () or Assertequals () method provided by the test framework. However, for more complex test scenarios, the assertion validation results with these bases can be quite awkward.
The main problem with using these base assertions is that the underlying details mask the test itself, which we do not want to see. In my opinion, we should try to make t
Naming Conventions are necessary to enhance the readability of the Code, so that you can understand what you want to express at a Glance. Standards are rules that make the code easier for later maintenance, it can also greatly improve the development efficiency. A normal website has a lot of JS Code. If you do not follow certain rules during the compilation process, you will not be able to understand what you wrote after writing it. This is a very tro
