Align slider-widget and side-widget

Hello there!

I’m struggling to align two things in my site, the slider widget and the side widget with the latest posts, I need to “eliminate” the red area on this image:

So that the two sides end on the same “line”, the right one I already achieved to change the width, but on the left side, there’s always some issue with the image, or the title, or overlaying something, and I don’t know if there’s something already avaible on the theme to adjust this, also, I don’t know why is not aligned because the template that I have imported from colormag was aligned.

Anyway, thank you for your time and any help.
