Somewhat new to html and css - html

Question

I´ve been working with Html for a bit these last 2 weeks and just started css today. I understand some of the basics of css (some of the elements and how to make the code look neater) but there are a few things i dont quite understand and haven´t been able to find so far. Such as making an image smaller for example. Can anyone explain to me why this css code isn't working?
h1{
Color: #8a1319
}
.name {
color: #ba454b;
}
/*help with this part please? Cant figure out how to properly make it smaller*/
.joke{
border: 2px solid red;
max-height: 250px;
width: 50%;
}
body {
text-align:center;
background: powderblue
}
<div class="name">
<h1>Dylan Carlson</h1>
</div>
<section>
<h1 class="title">

Answer 1

Remove the DIV around the image and add joke to the class:
<img src="http://www.jeremychin.com/repository/tickled/0355.jpg" class="joke">
Since you had joke as a class of the DIV, it applied to the DIV and NOT the IMG. Thus, the max height of the DIV was 250px and since the picture was larger, it overlapped.
A bit of advice: Keep CSS at the lowest level you can (the IMG in this case and not the DIV).

Answer 2

You are editing the image's parent div, that's why it's not working. Use the image's class instead.
.image{
border: 2px solid red;
max-height: 250px;
width: 50%;
}

Answer 3

Css is not for creating things on the browser it is for styling elements. Ii is used to make things look as desired. The code as per your question will make a div (if styled on to) have a border with 2px in size with red colour and the div would be having width 50 percent as per the availability space and a maximum height of 250px
