## Description

A minimalist plugin that automatically inserts non-breaking spaces (NBSP) after 
selected words and abbreviations. It helps prevent awkward line breaks (for example,
single-letter prepositions in Czech and Slovak). Works with most popular page builders
as well.

It automatically inserts non-breaking spaces (NBSP) after selected words or abbreviations
to prevent unwanted line breaks. This is especially important in languages where
short words (such as single-letter prepositions or conjunctions) should never appear
alone at the end of a line.

Unlike many traditional solutions that only work with the_content(),Speedx Smart
Line Breaks modifies text directly on the frontend. This means it also works reliably
with content generated by popular page builders such as Elementor, Divi, Bricks 
Builder, Kadence, Gutenberg, Classic Editor, and others.

The plugin has been tested on large content-driven websites, where performance and
reliability matter.

Simple setup, powerful control

After activation, the plugin already covers the most common Czech and Slovak typography
rules.
 You can easily extend or customize the behavior by adding your own words
or abbreviations in the settings.

Just enter words separated by commas, spaces, or new lines — Speedx Smart Line Breaks
will make sure those words stay connected to the following text.

This makes it ideal for:
 – Single-letter prepositions and conjunctions – Abbreviations–
Titles (Dr., Prof., etc.) – Numbers and units – Scales and measurements – Custom
language-specific rules – Examples of language-specific rules

🇨🇿 Czech / 🇸🇰 Slovak
 k, s, v, z, o, u, a, i, či, nebo, ale

🇩🇪 German
 Dr., Prof., z. B., u. a.

🇷🇺 Russian
 в, к, с, о

🇮🇹 Italian
 a, e, o

Speedx Smart Line Breaks is not limited to Czech or Slovak. Many languages have 
their own typographic conventions, and this plugin gives you full control to define
your own rules.

### Features

 * Works with common builders (e.g. Elementor, Divi, Bricks, Gutenberg, Classic 
   Editor, and more).
 * Simple setup – one field with a list of rules.
 * Minimal overhead – modifies only text nodes on the frontend.

## Installation

 1. Upload the plugin files to `/wp-content/plugins/speedx-smart-line-breaks/` or install
    the plugin via the WordPress Plugins screen.
 2. Activate the plugin through the “Plugins” screen.
 3. Go to Settings  Speedx Smart Line Breaks and adjust the list of words/abbreviations.

## FAQ

### Does it work with page builders?

Yes. The plugin adjusts text on the frontend using JavaScript, so it is generally
compatible with most builders and output methods.

### How does it work?

A non-breaking space (NBSP) is inserted after selected words/abbreviations. The 
browser then keeps the selected item together with the following word and prevents
a line break between them.

### Will it slow down my site?

In normal use the impact is minimal. The script runs once after the page loads and
modifies text nodes only.

### Is it compatible with cache plugins?

Yes. The modification happens in the visitor’s browser, so caching does not affect
it.

Skvělý plugin, který řeší přesně ten typografický detail, na který WordPress často
zapomíná. Vše funguje bez problému hned po aktivaci, nastavení je jednoduché a kompatibilita
s buildery je velké plus. Výsledkem je čistší a profesionálnější sazba textu bez
otravného zalamování. Super práce! 👌
