Thank you for your answer. I am creating a new topic.
I don’t know what you mean by the following advice.
About 1 and 2, should I replace all the code in the contents with the following code?
About 3, where can I change url?

– To change the images of Layout position 4 (cordia policy) you need make these steps:
1, Go to admin >> CMS >> Static blocks >> codia_policy
2, Go to content replace by code:

<div class=”policy “>
<div class=”container”>
<div class=”row”>
<div class=”policy-child col-md-3 col-xs-6 col-phone-12″>

</div>
<div class=”policy-child col-md-3 col-xs-6 col-phone-12″>

</div>
<div class=”policy-child col-md-3 col-xs-6 col-phone-12″>

</div>
<div class=”policy-child col-md-3 col-xs-6 col-phone-12″>

</div>
</div>
</div>
</div>

3, change url=”wysiwyg/codia/banner/banner-between_1.png”}}
