Как разместить два элемента рядом друг с другом?

Question

Рассмотрим следующий код :

#wrapper {
    width: 500px;
    border: 1px solid black;
}
#first {
    width: 300px;
    border: 1px solid red;
}
#second {
    border: 1px solid green;
}

<div id="wrapper">
    <div id="first">Stack Overflow is for professional and enthusiast programmers, people who write code because they love it.</div>
    <div id="second">When you post a new question, other users will almost immediately see it and try to provide good answers. This often happens in a matter of minutes, so be sure to check back frequently when your question is still new for the best response.</div>
</div>

Я бы хотел, чтобы два div были рядом друг с другом внутри div-обертки.В этом случае высота зеленого div должна определять высоту оболочки.

Как я могу добиться этого с помощью CSS?

#wrapper {
width: 1200;
border: 1px solid black;
position: relative;
float: left;
}
#first {
width: 300px;
border: 1px solid red;
position: relative;
float: left;
}
#second {
border: 1px solid green;
position: relative;
float: left;
width: 500px;
}

<div id="wrapper">
    <div id="first">Stack Overflow is for professional and enthusiast programmers, people who write code because they love it.</div>
    <div id="second">When you post a new question, other users will almost immediately see it and try to provide good answers. This often happens in a matter of minutes, so be sure to check back frequently when your question is still new for the best response.</div>
