Magento – how to remove css files from a custom template

csslayouttheme

I am using a separate template file only for one category For that i have set up a separate page layout everything is working fine

content from my page.xml

<page_product_view_brand translate="label">
        <label>Product View (left)</label>
        <reference name="root">
            <action method="setTemplate"><template>page/product_view_brand.phtml</template></action>
            <!-- Mark root page block that template is applied -->
            <action method="setIsHandle"><applied>1</applied></action>


        </reference>
        <reference name="head">
            <action method="removeItem"><type>skin_css</type><name>css/screen.css</name></action>
        </reference>
    </page_product_view_brand>

This page is uses totally different css files. So i want to remove all the css that is loading other than my required ones.

But i am not able to remove the css from my document.What am i doing wrong

EDIT:
Two places in page.xml

<block type="page/html_head" name="head" as="head">
 <action method="addCss"><stylesheet>css/screen.css</stylesheet></action>
</block>
.....................
<block type="page/html_customhead" name="customhead" as="customhead">
 <action method="addCss"><stylesheet>css/screen.css</stylesheet></action>
</block>

You're best of adding any changes to the local.xml to ensure the new rules are processed last.

[...]
<page_product_view_brand>
   <reference name="head">
      <action method="removeItem"><type>skin_css</type><name>css/screen.css</name></action>
   </reference>
   <reference name="customhead">
      <action method="removeItem"><type>skin_css</type><name>css/screen.css</name></action>
   </reference>
</page_product_view_brand>
[...]

Should do the trick

Magento – calling css using layout xml

You have an error in your xml, the <layout> tag at the end should be closed, but I will assume that it's a copy/paste mistake and that is not the problem

Your problem is here:

<default>
    <reference name="root">
        <block type="core/template" name="page_head" output="toHtml" template="page/html/head.phtml" />
        <action method="addCss"><stylesheet>css/normalize.css</stylesheet></action>
    </reference>
</default>

What you are doing is:

Referencing the root block in all pages, adding to it a block of type core/template that is using the page/html/head.phtml as its template.
Calling the addCss method of the page/html block (since the root is of that type if you look in the page.xml layout file)

What you should be doing is referencing the head block as the addCss function is in that one.

Now before answering your main question, I would like to put out a few remarks:

It is my understanding from reading the tutorials that Magento will load the default handle and apply to all the pages in this .xml file.

This is somewhat true, except that anything in the <default> handle, will applied website-wide, not just for pages of that particular layout file.

which class is used to load action method="addCss"? (I have looked in various Mage/Core/Block folders)

If you look at the page.xml file, you can find it. In fact there are 2 methods to add CSS files, addCss and addItem

<block type="page/html_head" name="head" as="head">
    <action method="addCss"><stylesheet>css/styles.css</stylesheet></action>
    <action method="addItem"><type>skin_css</type><name>css/styles-ie.css</name><params/><if>lt IE 8</if></action>
    <!-- etc. -->
</block>

From the type of the block, page/html_head, you would be able to figure out that the block is Mage_Page_Block_Html_Head. (It's in the format of module/path)

how do I set up the .xml file to add css to the pages in my module?

Since you need the css to be ONLY in you module's pages, you cannot put it in the <default> handle. As it would be loaded in all pages throughout the website.

But what you can do, is create your own "default" handle, and make all other handles "extend" it.

So using all that info, this is how your XML would look like:^tl;dr

<layout>
    <!-- First we create the default handle that should be applied to all
         of the module pages in this layout file-->
    <user_register>
        <reference name="head">
            <!-- There is no need to reference the root handle, we just
                 reference the head handle and call the addCss method -->
            <action method="addCss"><stylesheet>css/normalize.css</stylesheet></action>             
        </reference>
    </user_register>
    <!-- The next handle will match the BASE_URL/user/register/form path -->
    <user_register_form>
            <!-- This is the tag which "extends" the user_register handle-->
            <update handle="user_register"/>
            <block type="core/template" name="prefcentre_regform" output="toHtml" template="ps/prefcentre/signup.phtml" />
    </user_register_form>
</layout>

where do I need to locate my css for magento to find them?

Since you used css/normalize.css as the path for the CSS file, it should be located at frontend/default/default/css and not inside a subfolder.

Debugging Magento 2 CSS Files in Chrome Developer Tools

Google Chrome shows the source of the CSS and M2 uses LESS which is then coimpiled into CSS.

Chrome gets the LESS file source from the Source Maps provided in your theme files.

To update or edit styles of a Magento 2 theme you should do so by updating the less files and compiling either using Grunt or M2's server side LESS compilation.

You can find full details of CSS preprocessing in M2 in there documentation
