How can you make a quotation mark appear before a paragraph using pseudo-elements?

Adding Quotation Marks with ::before in CSS

You can use the ::before pseudo-element to insert quotation marks or other decorative symbols before a paragraph. This allows you to add visual cues without changing the HTML content.

Key Points
  1. 1

    Use ::before with the content property to insert the quotation mark, e.g., content: '“';.

  2. 2

    Set position: relative on the parent if you need precise control over placement.

  3. 3

    Style the pseudo-element with font-size, color, margin, or transform to match your design.

  4. 4

    Combine with ::after for closing quotation marks if needed.

Example: Quotation Mark Before Paragraph

In this example, the ::before pseudo-element inserts a gray quotation mark before the paragraph. You can adjust font-size, color, and position to match your layout and style preferences.

Best Practices
  1. 1

    Use pseudo-elements for purely decorative symbols to avoid altering semantic HTML.

  2. 2

    Ensure the quotation mark does not overlap text by adjusting padding or positioning.

  3. 3

    Combine with ::after for closing quotes if needed for visual consistency.

  4. 4

    Test across different screen sizes and browsers for proper alignment and display.

Scenario Questions

0-2 years experience
  1. 1

    How would you add an opening quotation mark before every paragraph using only CSS, without touching the HTML?

  2. 2

    What happens if you forget to set display: block on the paragraph when using ::before to add a quote?

2-5 years experience
  1. 1

    A designer says the blockquote quotes look broken on mobile — the ::before quote is overlapping the text. How do you debug and fix this?

  2. 2

    We’re using ::before to add quotes in a CMS-generated blog, but sometimes the quote appears even when there’s no paragraph content. How do you prevent that?

5-8 years experience
  1. 1

    We’re building a multilingual content system where quote styles vary by locale — how would you architect the CSS to support this without bloating the stylesheet?

  2. 2

    A performance audit shows our ::before quote styles are causing layout thrashing on low-end devices. What’s the root cause and how do you optimize it?

8+ years experience
  1. 1

    Our legacy design system uses ::before for quotes across 20+ products — we’re migrating to a design token system. How do you plan the deprecation and ensure no visual regressions?

  2. 2

    We need to support screen readers properly while keeping visual quotes via CSS. How do you balance accessibility, maintainability, and design consistency at scale?

Follow-up Questions

  • What happens if the paragraph is inside a nested container with its own ::before styles?
  • How would you handle this if the quote needed to change based on language?
  • Why wouldn’t you just use an actual quote character in the HTML?
