Underlining or placing quotation marks around the titles is not standard practice as these symbols serve specific purposes in different contexts. Underlining is often used to indicate hyperlinks, while quotation marks enclose direct quotes or phrases taken from external sources. By avoiding these symbols for white paper titles, any potential confusion can be prevented, and consistency with common website standards can be maintained.
Additionally, using bolding for white paper titles aligns with the conventional formatting approaches for headings and titles throughout web pages. It visually organizes the content, creating a clear hierarchy of information and assisting users in easily skimming and identifying what each title signifies. Bolding the titles makes it more likely that readers will quickly notice and understand the significance of the white paper within the provided list.
Therefore, when displaying white paper titles on a website, bolding serves as the most appropriate style to accentuate their importance and distinguish them from the body text, without introducing potential misinterpretations that could arise from underlining or the use of quotation marks.
