CSS: display a long string line-line with checkbox

I have a string with 255 characters (no space) and want to display it inline with a checkbox, not under. I have tried inline; inline-block; ... but it doesn't work. Anyone help?

<div class="item">
    <input type="checkbox" id="a">
    <label for="a">a</label>
</div>
<div class="item">
   <input type="checkbox" id="b">
<!-- 255 characters string here -->
    <label for="b">eyDlDLuT8A8AMTeyHSBXj4BeiWefQc1KWilxVWe7m7Vja1m9eEDc8iJ778jvaR2pCN2PcPcIWexrHehXSPJGqWaiSWfqSZL3AuZfOB0U3hlOCQMFWmqHWsERpWrF5YynmiJnn5mZoUP9TDPjW379O38BuBH9Q5zYlIRWgxAskcFT4DJAejiiIeu78jt1jsUU90RqV499IigZSqluOaJY3sptm0qADxE5M1JmnfEB9a8v7yihlrDq3Yy1MVMofBF</label>

<div class="item">
    <input type="checkbox" id="c">
    <label for="c">c</label>
