The final appearance of the selected text will be both bold and italic. When you apply text formatting in a word processing application such as Microsoft Word, Google Docs, or LibreOffice Writer, the effects are generally cumulative. This means that each formatting command adds its specific visual style to the selected text without removing previously applied styles, unless the command is designed to toggle a specific style off. In this scenario, first clicking the bold formatting button applies a bold font style. Immediately clicking the italic formatting button while the same text remains selected then applies an italic font style on top of the existing bold style. Therefore, the text will display with both a heavier weight and a slanted appearance, resulting in a combined bold and italic effect. This additive nature of text styles allows users to layer various formatting options for desired document appearance, affecting the overall look of the selected characters within your word processor document. This principle of cumulative formatting is fundamental to understanding how text styles work in modern word processing tools.
