Remove padding in text block

Squarespace is dynamic, as websites need to be as they get viewed on a huge number of screen sizes and resolutions. It is also on a grid system, so the block has to stay within those bounds. The slight variation in the padding is simply coming from those constraints. The padding you are setting is effectively a minimum of 5%, it is not an absolute value.

Using this code and targeting specific text blocks should mean that the background only gets applied around the text and should be more consistent:

#block-dd85f78398b41a11242b {
  .sqs-html-content {
    background-color:green;
    padding:5%;
  }
}
