Punctuating sentences

The rainbow stretched across the sky from the ice cream truck to the house down the lane.

The rainbow streched across the sky from, the ice cream truck to the, house down the lane.

There needs to be a comma after "sky" but no others. I can't think of a good reason to put a comma AFTER a preposition (from) or an article (the).

Based on the sentence, "The rainbow stretched across the sky from the ice cream truck to the house down the lane," the appropriate comma usage is as follows:

The comma should be placed after "sky," to separate the introductory phrase from the main clause. This is called a introductory comma. However, there should not be commas after the preposition "from" or the article "the" because they do not require comma usage.

To confirm this, you can refer to the website you provided, which explains different comma uses. The specific comma rule that applies to this sentence is the use of a comma after an introductory phrase.
