+We need to create a ```h1``` element with the text ```Hello World```, then we need to give all elements on your page the color of ```green``` in our ```body``` element's style declaration, and finally, we need add  to our ```body``` element  font-family of ```monospace```.
+
+ ### Solution
+ 
+ #### 1. Create a ```h1``` element with the text ```Hello World```:
+ 
+ add ```h1``` after ```</style>``` element:
+ 
+ ```css
+    <h1>Hello World</h1>
+```
+
+#### 2. Give all elements on your page the color of ```green``` and font-family of ```monospace``` in our ```body``` element's style declaration:
+
+add between ```<style>``` and ```</style>```:
+
+ ```css
+    color: green;
+    font-family: monospace;
+```
+
+#### Full solution
+
+```css
+<style>
+  body {
+    background-color: black;
+    color: green;
+    font-family: monospace;
+  }
+</style>
+
+<h1>Hello World</h1>
+```
