Honestly, I'm not the best person to ask about this. But I can give you some tips and also basic HTML. I'll leave some helpful links at the bottom of this page. (I also added a black box and changed to font to make it easier to read.)
The first thing you need to do is add some text to your webpage (unless it's image-exclusive)! You can do so using the p tags, or you can add headings using the following: h1, h2, h3, h4, h5, h6. h1 is the largest, while h6 is the smallest.
You can add links using the a tag! Like this:
Links can be added to most elements.
Images! Yeah! Woo! You can add height="...px" or width="...px" to change the width and height.
You can wrap the a tag around the img tag to create an image that is a link.
The tags you typically use to add text don't support line breaks as you know them. You can't press enter to create a new line, but it's okay! You've got the br tag to help.
The hr tag creates a horizontal line that you can use to divide your text...I personally don't use this one, but it's good to know that it exists.
The last thing I'll be showing you here is lists. You can use ul to make an unordered list, or ol to make an ordered (numbered) list!
You can add as many li tags as you'd like!
That's all I've got for you today, kiddos. Here are some helpful links, as promised.
