Textarea col is not responsive

I am presenting some data in a grid. The problem is that it is not responsive,when i minimize the page, the textarea part goes out and the delete and edit buttons too.How can this be solved and also to make the cols for the textarea fit to the content?

Parent Component

 <div className='container tbl' style={{marginTop:'20px'}}>  
                {Object.entries(rules).map((rule) => (
                     <Rules key= {rule[0]} rules={rule} onLoad={getRules}/>
                ))}    
            </div>

Child Component

export default function Rules({rules, onLoad}:{rules:string[],onLoad:()=>void}) {
    
  return (
        <div key={rules[0]} className='tbl_rules'>
            <div className='box-1'><h6>{rules[0]}</h6></div>
            <div ref={focusDiv} className='box-2'>
                <RulesText />
            </div>
            <div className='box-3'>
            <button 
                id={rules[0]}
                type="button" 
                className="btn btn-sm btn-danger"
                onClick={onDeleteHandler}
                ><RiDeleteBin5Fill className='rules_icon'/>Delete</button>
            </div>
            <div className='box-4'>
                <button 
                id={rules[0]}
                type="button" 
                className="btn btn-sm btn-info"
                value={isEditing ? 'Save' : 'Edit'}
                onClick={onEditHandler}
                >
                <RiEdit2Fill className='rules_icon'/>{isEditing ? 'Save' : 'Edit'}</button>
            </div>
        </div>
  )
}

Child Component

export default function RulesText({ruleText, readOnlyStatus}:{ruleText:string, readOnlyStatus:boolean) {
    
    const[textValue, setTextValue] = useState(ruleText)
    
    return (
        <textarea  
            rows={5}
            cols={50}
            readOnly={readOnlyStatus}
            value={textValue}
           />
  )
}
