Hi everyone,

We are using Trust theme by Impact. We recently created two custom modules in one page. The problem we are trying to solve is that when we add custom module 1 it works fine but then when we add custom module 2 it looks like it affects the css of custom module 1 so it breaks. How can we avoid that? ps: I tried adding the code for clarity but then my post was flagged as spam. Thanks in advance!

hi @HadeelGamal,

do you use the same classes in those modules or style settings?

The best practise - if you’re using style settings in the HTML+Hubl “tab” of the custom module is to write it like this:

```lia-code-sample
{% require_css %}
<style>
...
YOUR STYLE INFO
...
</style>
{% end_require_css %}

...

<div>
YOUR MODULE LAYOUT
</div>

```

to avoid possible rendering issues or style overwrites I add an auto-class to the modules like this

```lia-code-sample
<div class="moduleName-{{name|md5}}">
MODULE LAYOUT
</div>

```

the {{name}} function adds the name of the module(most times auto generated) as class. But to be 100% sure nothing is getting overwritten I add the [|md5](https://developers.hubspot.com/docs/cms/hubl/filters#md5) filter. This converts the name to a md5 hash. Therefore: You get auto generated classes

To access them you can write your module (only in the HTML+Hubl “tab”) like this

```lia-code-sample
{% require_css %}
<style>
.myModule.module-{{name|md5}}{
background:{{ module.styles.background_color.css }};
}
</style>
{% end_require_css %}

...

<div class="myModule module-{{name|md5}}">
YOUR MODULE LAYOUT
</div>

```

tipp: if you want to use the |md5 filter add something before it like “module-” (see in the example above).

Another option could be to use the [scope\_css](https://developers.hubspot.com/docs/cms/building-blocks/module-theme-fields-overview#generated-css) function but keep in mind that it doesn’t work for every style field.

```lia-code-sample
{% require_css %}
<style>
{% scope_css %}
...
SOME STYLE
...
{% end_scope_css %}
</style>
{% end_require_css %}

```

For posting code snippets in the community:

While writing an answer/post - click on the “…” in the post editor(the first icon from the right) and you’ll see the \</\> icon. This is the “code-option”

best,

Anton

Hello @HadeelGamal

You can utilize the `require_css` cope\_`scope_css` in your `module.html` file. However, it’s important to note that if you control CSS from the editor, conflicts may arise when using the module multiple times on the same page. To address this issue, you can scope the CSS to each individual module instance by enclosing the CSS within the ``scope_css` tag.

Please refer to the attached image for a clearer understanding of how to write CSS within `module.html`.

Hello @HadeelGamal

I have identified the issue in your code. It appears that you have added some CSS properties directly on the HTML & body tags within the second module. Unfortunately, these properties are conflicting with the rest of the page because they affect global elements.

To resolve this conflict, I have made the necessary modifications by enclosing the second module within a wrapper and applying the required CSS properties to this wrapper instead. This way, the changes will only affect the specific module and not interfere with other elements on the page.

Please review the attached image for a visual representation of the changes. In the image, I have marked the part of the CSS that needed to be removed from the global scope and applied it to the new wrapper.

Now, the second module should be working properly without affecting other parts of the page. To see the changes in action, you can check the link provided below.
