Text Widget

Do you know how to use HTML?

A little bit

In that case, you will need to use HTML to add your banner images to the Text widget – possible with some inline CSS to float to the 2 lower banners side-by-side.

Well in that case, then no. I don’t know HTML that well to just write it and insert it.
Can anyone else help?

Those are going to be really small ads? Your sidebar is only 178px wide?

Yes but I have other ads up that are 250 x 250.
I wanted to try a small tiled one with 4 125×125 ads to test it.

Those are getting cut off when the site is resized – does that matter?

What does that mean?! lol

Try looking at your site in a smaller browser window or on an iPad or phone. Those ads are outside the sidebar and thus get cutoff (or need a scrollbar). It’s not horrible, just asking if you were aware of it.

I wasn’t aware. but that is ok.

So back to your question, this really is basic HTML and CSS – so you might want to invest a bit of time learning more ?? – but something like this should work:

HTML:

<div class="fourads">
<div class="ad1">
Ad 1
</div>
<div class="ad2">
Ad 2
</div>
<div class="ad3">
Ad 3
</div>
<div class="ad4">
Ad 4
</div>
</div>

CSS:

.fourads {
  //add styles here if needed;
}
.ad1, .ad2, .ad3, .ad4 {
  width: 125px;
  height: 125px;
  border: 1px solid red;
  margin: 3px;
  float: left;
}

.ad3 {
  clear: both;
}
