How to make the block increased in size when the switch is pressed(input radio)?

The situation is this: there are 3 blocks, the first has switches(radio buttons) labelы which acquire the style specified in the code when clicking on the text. Other 2 units are below and should increase in size when you press the switch. Not much kick I'm a beginner(self-taught), I can not figure out how to do it, tried but the design doesn't work. Here is the code and screenshots:

<div id="pricing" class="offer">
 <div class="container">
 <div class="offer-section">
 <!-- The switch block -->
 <div class="block-1 choose-block">
 <h3 class="title">Choose your perfect plan</h3>
 <span>you are</span>
 <form class="switcher">
 <input type="radio" id="individual" name="check" checked>
 <label class="switch-btn-1" for="individual">Individual</label>
 <input type="radio" id="company" name="check">
 <label class="switch-btn-2" for="company">Company</label>
 <p>Thus much I thought proper to tell you in relation to yourself, and to the trust I reposed in you.</p>
