Why Line Breaks Break Formatting in Blogs | Rune

You've carefully written a blog post, but after pasting into your CMS, the formatting is broken. Sentences end abruptly. Paragraphs look wrong. The culprit? Line breaks from your source text. Here's why this happens and how to fix it.

How Line Breaks Differ

Hard Line Breaks

A "hard" line break (created by pressing Enter) tells the system to start a new line no matter what. In HTML, this is <br> or actually creates a new paragraph element.

Soft Line Breaks (Word Wrap)

A "soft" line break (automatic word wrap) adjusts based on screen width. Text flows naturally without forced breaks.

Why Source Text Has Line Breaks

When you write in certain editors or copy from PDFs:

• The text has hard line breaks at the edge of the visible area.
• These breaks become permanent in the text.
• Pasting into a blog CMS preserves these breaks.

The Blog Formatting Problem

What You Expect

This is a paragraph about productivity. It should flow naturally and wrap based on the reader's screen width. No breaks in the middle of sentences.

What You Get

This is a paragraph about productivity. It should
flow naturally and wrap based on the reader's
screen width. No breaks in the middle of
sentences.

The hard line breaks from the source make sentences wrap at wrong points.
