Cnblogs-Theme-SimpleMemory: A Cnblogs Skin You Configure, Not Fork

What SimpleMemory is, and the problem it removes

Cnblogs gives every account a blog, but the stock templates are plain and the settings page exposes only a handful of options. SimpleMemory sits on top of that: the README describes it as an extension and beautification plugin built on the Cnblogs SimpleMemory theme, and its three advertised properties are out-of-the-box use, a configurable interface, and compatibility with PC, tablet and mobile. That is the whole pitch. You are not replacing Cnblogs. You are restyling it.

The audience is narrow and specific. It is for people who already write on Cnblogs and want a denser, more magazine-like reading experience without moving their archive to a static site generator. The repository's only topic is cnblogs, and the online demo is a live Cnblogs blog, which tells you the project has no ambition beyond that platform. If you are choosing a blogging engine rather than a skin, this is not a candidate.

How the theme loads: a built bundle, not a plugin runtime

The build is the architecture. The repository root holds src/, dist/, webpack.config.js, postcss.config.js and a package.json whose scripts run webpack and then PostCSS over src/style/simpleMemory.css to produce dist/simpleMemory.css. In other words, the stylesheet you actually load is a compiled artifact, and the source CSS is not what the browser sees.

The dependency list explains what the bundle contains. It pulls in bootstrap, gsap, highlight.js, clipboard, snapsvg-cjs, optiscroll and popperjs, among others. Those are not Cnblogs platform libraries; they are bundled into the theme. That is why the theme can animate, highlight code and offer a custom scrollbar on a platform that offers none of it natively. It also means the page weight is the theme's responsibility, and every one of those libraries is a piece you inherit when you paste the bundle into your blog.

There is a second delivery path. The README links a jsDelivr badge for the repository, which is the normal way a Cnblogs user would load a GitHub-hosted asset, and the homepage points at a versioned documentation path under v2.1. The dist/ directory and the docs/ directory are both checked in, so the published documentation and the published bundle live in the same repository as the source. The trade-off is that a fix in src/ only reaches users after a build and a release, not when the commit lands.

Installing SimpleMemory on a Cnblogs blog

The README does not walk through installation; it links to the documentation site at bndong.github.io/Cnblogs-Theme-SimpleMemory/v2.1/dist/ and to a live demo blog. What the repository does tell you is how the maintainer builds and serves the artifacts locally, and that workflow is the honest starting point if you want to inspect or modify the theme before using it.

Clone the repository and install the dev dependencies. The package.json declares webpack, PostCSS and the rest under devDependencies, so a plain install is enough to get the toolchain:

git clone https://github.com/BNDong/Cnblogs-Theme-SimpleMemory.git
cd Cnblogs-Theme-SimpleMemory
npm install

The build script is the one named build. It runs webpack against webpack.config.js and then pipes the source stylesheet through PostCSS into dist:

npm run build

After that, the repository offers a local preview server on port 3100, served from dist with CORS enabled. This is useful for checking a change before you touch your blog:

npm run server

You should then be able to open http://localhost:3100 and see the built theme assets. For the actual blog, the documented route is the documentation site's configuration page plus the theme settings in your Cnblogs account; the README gives no copy-paste snippet for that step, so treat the documentation as the source of truth for which files to paste where. Note the version mismatch you will encounter: package.json declares version 2.0.0 while the newest release tag is v2.1.7, so the package field is not a reliable version indicator.

Where SimpleMemory stops being the right choice

The theme is bound to Cnblogs. Every asset is delivered through the platform's settings, and the demo, the documentation and the topic all assume a Cnblogs account. If your plan is to migrate off Cnblogs, or to run the same theme on a self-hosted site, there is nothing here for you. The bundle is not packaged as a standalone npm library you can drop into an arbitrary HTML page, and the README documents no such use.

The second limitation is the build dependency. Because the shipped CSS is compiled from src/style/simpleMemory.css through PostCSS, and the JavaScript goes through webpack, changing anything real means running the toolchain. A user who only wants to tweak a colour can edit the built file, but that edit will be overwritten the next time the bundle is regenerated, and it will not match the source. There is no documented CSS variable layer or runtime theming API in the README; the configurability it advertises lives in the theme's interface settings, not in a stylesheet you own.

The third is maintenance visibility. The last push to the repository was on 2026-03-29, and the newest release is v2.1.7 from 2025-08-25. That is recent enough that the project is not abandoned, but the gap between releases means a bug you hit today may already be fixed on the default branch v2 without a tagged release. The README's own badges still reference the master branch for last commit and licence, which is a sign the documentation has not fully caught up with the branch rename.

How it compares to building your own Cnblogs skin

The realistic alternative is not another Cnblogs theme; it is writing the CSS and JavaScript yourself and pasting that into the Cnblogs settings page. The difference in approach is total. A hand-rolled skin starts from the platform's markup and adds exactly what you need, which keeps the page light and leaves you with code you can read line by line. SimpleMemory instead ships a bundle that already contains bootstrap, gsap, highlight.js, snapsvg and optiscroll, and gives you configuration knobs on top of it. You trade control over page weight for a layout that works on day one.

The second alternative is moving to a static site generator and hosting the result yourself. That removes the platform constraint entirely and gives you a build you own, but it also moves comments, search visibility and the archive you already have on Cnblogs. SimpleMemory's value proposition depends on you not wanting to make that move. If you would make it eventually, the theme is a delay rather than a solution.

Licence, upgrade cost and what a version bump means

The README states the project is released under the MIT License and links a LICENSE file at the repository root, so the source is permissive. One inconsistency is worth flagging: the package.json license field reads ISC, not MIT. For a theme you load as a built asset rather than redistribute as a package, this is unlikely to matter, but if you plan to fork or repackage it, read the LICENSE file itself rather than either metadata field. This is not legal advice; it is a pointer to the two conflicting statements.

Upgrading is a manual operation. There is no documented migration script and no rollback procedure in the README. Release history shows v2.1.5 in July 2024, v2.1.6 in December 2024 and v2.1.7 in August 2025, so the cadence is roughly one or two tagged releases a year. Before upgrading, keep a copy of the settings you configured in your Cnblogs theme panel, because the README does not describe an export or import path for them. If a release changes the expected configuration shape, the only recovery is restoring your previous values by hand.

Editorial conclusion

Adopt SimpleMemory if you already publish on Cnblogs and want a configurable layout without maintaining a build pipeline; the repository's last push was on 2026-03-29 and the newest release is v2.1.7 from 2025-08-25, so read the changelog before assuming a fix landed. Do not adopt it if you need a self-hosted site, server-side rendering, or a theme you can modify without a webpack and PostCSS toolchain. Before you commit, verify which branch your blog's settings page points at, since the default branch is v2 while the README's commit and licence badges still link to master, and check the licence file in the repository rather than the package.json field, which reads ISC.
