lc_glass

Frosted glass focus areas with `lc_glass_*`

Use lc_glass_* on infographic slides when you want a soft, frosted “glass” panel over part of your artwork—great for drawing attention to KPIs, callouts, or busy charts without redesigning the whole slide.

When to use it

Highlight a metric or message with a subtle frosted panel
Soften a busy background behind text or charts
Pair with narration highlights so the glass area appears when you want it in the story

Download sample SVG — includes a glass rectangle named lc_glass_1 you can try in Cast.

What you need in your SVG

A rectangle (<rect>) whose ID includes lc_glass_ (for example lc_glass_1 or chart_lc_glass_focus).
The rectangle’s position and size in the design tool define where the frosted area appears on the slide.

This page covers standalone glass on the slide. For click-to-reveal modal glass, use lc_action.

How to set blur in Cast

Open your Custom (infographic) slide in Cast Designer.
Open Override SVG Variables for that slide (same place you personalize other SVG IDs).
Find the variable that matches your glass rectangle’s ID (for example lc_glass_1).
Enter a blur amount as a simple number, or add px if you prefer—examples: 10, 20, 13.5px.
Leave the value empty if you want Cast to use the default blur strength.

Blur strength

You can use values from 0 (very little blur) up to 100 (strongest).
If you leave the field blank, Cast applies a comfortable default blur (20px).
If you enter a number above 100, Cast treats it as 100.

Tips for a polished look

Match the glass rectangle’s corners to your layout (rounded corners in the SVG carry through to the effect where supported).
Adjust blur in small steps until the background feels readable but still softened.
Avoid IDs that contain lc_glass_effect unless you intend that separate behavior—stick to names like lc_glass_* for this frosted panel.

Designer view (placeholder)

Use this spot for a screenshot of Override SVG Variables or the slide editor showing the glass variable.

Playback & narration (placeholder)

Optional second visual: glass during playback or with highlights.

During playback, the frosted area follows the same highlight behavior as other slide elements you configure in narration—so you can reveal or soften the panel as the story progresses.

If something looks wrong

What you notice	What to try
No frosted area	Check that the shape is a rectangle and the ID includes `lc_glass_`.
Cast won’t save the blur	Use a number between 0 and 100, or add `px` after the number (for example `24px`).
Too strong or too soft	Lower or raise the blur value in small steps.

Simple example

In your SVG, a glass region might look like this (sizes and position are up to your design):

<rect id="lc_glass_kpi" x="120" y="180" width="420" height="180" rx="16" />

Then set your preferred blur in overrides (for example 18).
