Google Docs uses a standard font when you create a document. If you aren’t happy with its appearance, here’s how you can change the default font instead of manually adjusting it each time.
创建文档时，Google文档会使用标准字体。 如果您对它的外观不满意，可以通过以下方法更改默认字体，而不必每次都手动调整它。
Fire up your browser, open a Google Docs file, and then change the font. Click the drop-down box and make sure the Style is set to “Normal Text,” as well. This refers to the main text style (excluding titles or headings) used throughout your document.
启动浏览器，打开一个Google Docs文件，然后更改字体。 单击下拉框，并确保将样式设置为“普通文本”。 这是指整个文档中使用的主要文本样式(标题或标题除外)。
Note: Certain formatting can also be applied to the default font, such as size, bold, underline, color, and highlight color.
注意：某些格式也可以应用于默认字体，例如大小，粗体，下划线，颜色和突出显示颜色。
Type out a few words or lines in the font of your choice, and then highlight them with your mouse.
用您选择的字体键入一些单词或行，然后用鼠标突出显示它们。
Next, click Format > Paragraph Styles > Normal Text, and then select “Update ‘Normal Text’ to Match.”
接下来，单击格式>段落样式>普通文本，然后选择“更新'普通文本'以匹配。”
Before you save your changes to Normal Text, you can change the default font for titles and headings, as well.
在保存对普通文本的更改之前，您还可以更改标题和标题的默认字体。
To do so, select one of the options from the drop-down menu, and then begin to type in the font you want. We’ve chosen “Title” for this part, but you can change any of the options listed below.
为此，请从下拉菜单中选择一个选项，然后开始键入所需的字体。 我们为此部分选择了“标题”，但是您可以更改下面列出的任何选项。
Then, just as before, head to Format > Paragraph Styles > Title, and then click “Update ‘Title’ to Match.”
然后，像以前一样，转到“格式”>“段落样式”>“标题”，然后单击“更新“标题”以匹配”。
To save this as the default style every time you open a new document, click Format > Paragraph Styles > Options, and then click “Save as My Default Styles.”
要在每次打开新文档时将其保存为默认样式，请单击格式>段落样式>选项，然后单击“另存为我的默认样式”。
If you ever want to reset the font back to the original defaults, go to Format > Paragraph Styles > Options, and then click “Reset Styles” to revert them.
如果您想将字体重置为原始默认设置，请转到“格式”>“段落样式”>“选项”，然后单击““重置样式””将其还原。
That’s it! Next time you open a new document and type, your text will be in your chosen font by default.
而已！ 下次打开新文档并键入时，默认情况下，文本将采用您选择的字体。
