Here is the same CSS as before, but with the input box's text color set to black:
```
*, *:before, *:after { padding: 0; margin: 0; box-sizing: border-box; }
body { height: 100vh; background: #1c1c1c; }
.container { width: 40%; top: 50%; left: 50%; background: #2c2c2c; border-radius: 10px; min-width: 450px; position: absolute; min-height: 100px; transform: translate(-50%,-50%); }
#addtodo, #todolist { position: relative; padding: 30px 20px; }
#todolist { border-radius: 10px; width: 100%; background-color: #2c2c2c; margin-top: 10px; }
#addtodo input, #addtodo button { height: 45px; border-radius: 5px; font-family: sans-serif; position: relative; }
#addtodo input { width: 75%; padding: 12px; color: black; font-weight: 500; font-size: 15px; border: 2px solid #444444; }
#addtodo input:focus { outline: none; border-color: #3a9eff; }
#addtodo button { float: right; font-weight: 500; font-size: 16px; background-color: #3a9eff; border: none; color: #ffffff; cursor: pointer; outline: none; width: 20%; }
.todo { border-radius: 5px; align-items: center; justify-content: space-between; border: 1px solid #444444; cursor: pointer; background-color: #383838; height: 50px; margin-bottom: 8px; padding: 5px 10px; display: flex; }
.todo span { font-family: sans-serif; font-size: 15px; font-weight: 400; color: #e0e0e0; }
.todo button { background-color: #3a9eff; color: #ffffff; border: none; cursor: pointer; outline: none; height: 100%; width: 40px; border-radius: 5px; }
