trying to figure out the class contact-info, font-size: 0.9em; then remove padding,margin, list styling/?

I'm unsure what you mean but to write the CSS code for getting doing this would be like:

css .contact-info{ font-size:0.9em; padding:0; margin:0; list-style-type:none; }

If your trying to do this within the html page then use this:

class="contact-info" style=" font-size:0.9em; padding:0; margin:0; list-style-type:none;" then your closing tag here

the task states: Select the unordered list with the class contact-info and set the font size to 0.9em. Then, remove all margin, padding, and list styling.

to select an element with a specific class you can use

element.class-name {


}

since the tasks ask you to select an unordered-list with a class of contact info you would use

ul.contact-info {


}

to remove margin, padding and list styling you would just set the margin and padding attributes to 0 inside the selector and set the list-style to none:

ul.contact-info {
font-size:0.9em; 
padding:0; 
margin:0; 
list-style:none;
}

this was tricky because it was not part of the tutorial and what I followed into my work-space.

the ul. before the contact-info worked

thank you!
