When writing a novel online, the space before each paragraph can be typed in the following ways: 1 Use the auto-space function in your text editor or writing software. These functions usually add a space at the end of the text. 2 Enter "t"(tab) in the text input box and press enter to add a space at the end of the text. 3. Use the "tab" key on the keyboard. After pressing the tab key, a tab will pop up. At this time, pressing the enter key will also cause a space to appear. 4. Use smart input devices such as enthusiasts in the field of online literature. These devices will automatically identify tabs and spaces in the text and fill them in automatically. It is important to note that the characters and format of spaces may be slightly different in different operating systems or text editors. Therefore, it is best to check the relevant instructions or examples when using these functions to ensure that the spaces in front of each paragraph are correctly typed.
