joomla blog layout with helix

Hi Muntasir, thnx,
it works but then there is less margin-left like here: https://mero.arkiadesign.de/bodensysteme-21/service-bodensysteme/bodensysteme-projektberichte-2.html?field1%5B%5D=deutschland&gsearch=1&moduleId=393#gsearch-results

this is the same page but after filter searching (with search results)

can you give me the code so that margins before and after filtering are the same, thnx :-)

Update!!!! the code is not good for it chages each side!!!!

#sp-main-body{
  padding-left:40px !important;
}

This is not the right solution.
Your layout looks like you were activated Fluid Width option for the Main Body section, and then through CSS crutches began to correct it.
For example, this code for what?

@media (min-width: 1200px){
body.view-featured #sp-main-body .row{
    max-width: 1140px;
    margin:0 auto;
}

In fact, you recreate the CONTAINER option, which also does the same from the box. Remove padding-left: 40px, delete your code for body.view-featured #sp-main-body .row and simply disable the Fluid Width option for Main Body.

Pavel!!!!!!!!!!!
You saved not my day but my life!!!!!!!
Thnx so much. there where so many page with blog layout, joomla articles where I had the problem with no margins on the sides! I am so happy man!

Can u help me for another prob? It is about a displaying news nicely with joomla articles as source, where I can click on "read further".
The joomla article addon in PB is not very helpful for I need lists in the news text and this does not work. see here: https://mero.arkiadesign.de/
scroll down to the section "/ NEWS
AKTUELLE PROJEKTE" ( would like to send screenshot but dont know how, cant attach anything)

I wrote so much, I found another solution, thnx
