Product description text is becoming stacked

Topic summary

A single product’s description renders in a stacked/narrow layout on a Shopify store, while other products display normally. The issue appears isolated to that product page.

Suspected cause:

  • Pasted/embedded HTML in the product description likely introduced restrictive layout styles or malformed markup.

Proposed fixes and checks:

  • CSS overrides: add max-width/width rules for the description containers in the theme’s base.css (main stylesheet). This did not take effect because the base.css file is reported as corrupted.
  • Content cleanup: in the product editor, use “Clear formatting,” then save. If unresolved, switch to “Show HTML,” copy the description, sanitize it with an online HTML cleaner, paste back, and save.
  • Workaround for corrupted stylesheet: inject the CSS directly into theme.liquid (the theme’s main layout file) above the tag so the browser loads the fix.

Status and next steps:

  • Clearing formatting alone did not resolve it; CSS added to base.css was ineffective due to file corruption.
  • Further action is to clean the description HTML and/or place the CSS fix into theme.liquid. No confirmed resolution yet; troubleshooting is ongoing.

Hi. As you can see in image my product description has just become stacked, and I am not sure why.

This specific product is (link here), and it is only this product that has this issue.

It looks awful so if I could please get some help to get it back to normal format like this, that would be great:

Hi @salil2000 ,

Please go to Actions > Edit code > Assets > base.css file and paste this at the bottom of the file:

.product__info-container .product__description .page-width {
    max-width: 100%;
    padding: 0;
}
.product__info-container .product__description .product__info-wrapper {
    max-width: 100% !important;
    width: 100% !important;
}

Hi @salil2000 ,

Can you share your store URL so that I can help you check further?

Look forward to your response.

Best,

Hi @salil2000

You copied the HMTL of the description, which caused the issue. Please go to edit that product, in Description, click Clear formatting to solve the issue.

Unfortunately this did not work. Thanks.

Did you save your product page after Clear formatting? Or you can click Show HTML, copy description of that product, use an online straightforward HTML tool to clear HTML of description, paste it back to description of that product, save and check again.

Hi @salil2000 ,

I checked and your base.css file code is currently corrupted, so when you add new code it won’t recognize it.

Please try adding the following code at theme.liquid file, above the ‘’ tag:
