Hide Tagged Posts On Tumblr Page

Question

Okay, so here's the deal. I've searched for about a week now on multiple sites including this one on how to hide specifically tagged posts from the Index Page & Tagged Page from my Tumblr blog. To make it easier, keep in mind that I do have some knowledge of html & css, as this is my 4th Tumblr theme that I've made within a year, and am getting better as I go along. So, to not waste your time I have already repeatedly tried these methods:

    1. <div id="posts {TagAsClasses}"></div>
    2. <div class="posts {TagAsClasses}"></div>
    3. {block:Posts}
       {block:HasTags}{block:Tags}<span class="tagged-{URLSafeTag}">{/block:Tags}{/block:HasTags}
       (*post content would go here*)
       {block:HasTags}{block:Tags}</span>{/block:Tags}{/block:HasTags}
       {/block:Posts}

None of these worked. Originally I had an id selector for my post content but changed it to a class since every time I would put in {TagAsClasses} it would mess up the entire page and posts div to no longer correspond to the CSS.

When I tried class, my page looked exactly the same, completely ignoring the {TagAsClasses}.

When I tried the third method, I had to use this for the CSS:

    .tagged-HIDDEN {
    {block:IndexPage}
    display:none !important;
    {/block:IndexPage}
    {block:TagPage}
    display:inline !important;
    {/block:TagPage}
    }

"HIDDEN" would of course would be any tag I put in for the posts I want to hide. When I do this, involving "!important" (this was what I was instructed to do from a another blog I visited), my blog won't even load when I get to a page that has the posts I want hidden (I use pagination). When I take out "!important", my blog loads but the tagged posts will show up, just with the CSS a little messed up.

I've tried everything, I even tried to change

    <span class> to <span id>

after I changed

    <div id posts> to <div class>

because I thought the span would become stronger and work, but the I ended up getting the same thing as when I used "!important" as I mentioned earlier.

So now that you've seen all the options I've tried, here's my complete html/css of my blog: ℂħёℓ§εå ...............

Ignore the missing head and !D0CTYPE html tags, they're in my blog they just won't show up here.

Answer 1

Here's what I did, basically I used tumblr's META tags to have different CSS depending on the page.

<head>
//Your head and CSS stuff here
{block:IndexPage}
<style>
.BLOCKME {display:none !important;}
</style>
{/block:IndexPage}
</head>

This will block any post with the tag BLOCKME from being displayed on the main page, you can also use {block:TagPage} {block:PermalinkPage} and {block:SearchPage}

A side note as well your posts must also contain class="{TagsAsClasses}"
