Is there a way to get Source Mode to not show styles?

I think I solved the problem.
Now I am using the Inconsolata font and using the following css.

/* list Indent */
.mod-cm6 .HyperMD-list-line.cm-line {
    padding-top: var(--list-spacing);
    padding-bottom: var(--list-spacing);
    text-indent: 0 !important;
    padding-inline-start: 0 !important;
}

/* quote Indent */
.mod-cm6 .HyperMD-quote.cm-line {
    text-indent: 0 !important;
    padding-inline-start: 0 !important;
}

/* codeblock Indent */
.markdown-source-view.mod-cm6 .cm-line.HyperMD-codeblock {
    padding-left: 0;
    color: var(--code-normal);
}

/* all source mode font */
/* .markdown-source-view {
    font-family: var(--font-text);
    font-size: var(--font-text-size);
} */

/* codeblock font */
.cm-s-obsidian .HyperMD-codeblock {
    font-family: var(--font-monospace);
    font-size: var(--font-text-size);
}

/* inline-code font */
.cm-s-obsidian span.cm-inline-code {
    color: var(--code-normal);
    font-size: var(--font-text-size);
    background-color: var(--code-background);
    vertical-align: baseline;
}

/* ident line position */
.markdown-source-view.mod-cm6 .cm-indent::before {
    content: "\200B";
    display: block;
    width: 0;
    border-right: var(--indentation-guide-width) solid
        var(--indentation-guide-color);
    color: transparent;
    position: absolute;
    top: 0;
    bottom: 0;
    transform: none;
}

The indentation of the list and code block is now correct.
