How do you add a margin in html (not css)? The challenge asks you to center an image and add 30 pixel to the bottom.

In the how to build a website tutorial, one of the challenge questions asks you to center the profile picture and add 30px to the bottom; the code they show is HTML. The video shows how to o this in CSS, but not HTML.

You can add css styles directly in the HTML by using the <style></style> tags in the <head> section of your HTML. For example if you wanted to add a margin-bottom to your <html> element then you could use either a local stylesheet in your HTML like so...

     html {
          margin-bottom: 30px;

Another way is to use in-line css on the tag itself - like...

<html style="margin-bottom: 30px;">

Does this help?

Hey Alicia,

I'm not sure which challenge you are referring to as you did not link from there (it's always best to use the "Get Help" button located in the challenge / video / quiz as this then links directly to where you are).

But, just double check, there is probably a tab in the challenge window that is the CSS file. You would just click on that to switch to the file. Often, the challenges will have multiple tabs for the different files needed in the challenge.


Thanks Jason...you were right, there was a tab and I did not see it. Thank you! I watched the videos twice and could not figure out why they were asking me to do these steps in HTML and not CSS.

I appreciate the tip on clicking the Get Help to ask a question as well.

This was a great opportunity to experience the help of the community.

Thanks again, Alicia

Can you link to the challenge that you're referring to? That said, you can add CSS styles in HTML via the style tag on the element or in the head of your HTML document.

Here is how you would add styles to the image via CSS:

/* this would be one way to do it */
img {
    margin-top: 0;
    margin-right: auto;
    margin-bottom: 30px;
    margin-left: auto;

And here is one way you could do the same thing via HTML:

<img src="whatever_your_src_is" style="margin-top: 0px; margin-right: auto; margin-bottom: 30px; margin-left: auto;" width="width_here" height="height_here" alt="alt_text_here">

Hope this helps!


thanks for your help Erik! Turns out there was a CSS tab that I missed, but this is good information for me to have as well.

I appreciate you taking the time to answer.
