Issue

In case you have applied a custom background image or color to your site, SharePoint lists in quick edit mode might not be obvious for end users, and they might find it difficult to use the editing feature in the list, see the following image for example:

Not cool, right? We can't see the borders.

Solution

We need to apply a CSS customization to convert the background of the search box into white, to improve the user experience, and make it more visible. To fix it, please follow these steps:

Step 1: Open branding and site customization tool

Go to Site Settings > ShortPoint Dashboard > Site Customizations > Customize my site.

Step 2: Paste Custom CSS code

Go to Utilities > Custom CSS and paste the following CSS code:

.ms-listviewtable .ms-listviewgrid td{
  border-color: #777 !important;
}

.ms-listviewtable .ms-listviewgrid th{
  border-color: #777 !important;
}

.ms-InlineSearch-Outline-Empty {
    border-color: #777
}

Now click Apply, then Publish.

Result

Better, right? :)

You can change to ones you like as well.

Thank you!
